WARNING: IF THE TROUBLE CONDITION PROTECTIVE SIGNALING SYSTEM SOUNDS
AND/OR FLASHES, IT IS A WARNING OF A POSSIBLE SERIOUS SITUATION AND
REQUIRES IMMEDIATE ATTENTION.
CAUTION: The SAFEPATH® printed circuit boards are sensitive to static electricity and have
delicate components mounted on a board. Discharge any static electricity from your
body by touching a grounded object, such as a metal screw, which is connected to
earth ground. Handle the board by its edges and be careful not to twist or flex it. The
SAFEPATH Panel is to be installed in a static free area, and the installer is to properly
attach grounded wrist straps before touching any static sensitive areas. After handling
SAFEPATH® printed circuit boards, the panel should be tested in accordance with
Section 3-5 “System Checkout” of this manual to verify that the printed circuit board is
functioning properly.
This SAFEPATH® Panel will not work without power. The SAFEPATH® Panel is powered by 120VAC
or 220VAC. 24VDC re-chargeable batteries provide back-up power. If both sources of power are cut off
for any reason, the SAFEPATH® Panel will not operate.
DO NOT assume any installation, operation and testing details not shown in this manual.
The SAFEPATH® Panel shall only be operated with the dead front panel properly in place.
WARNING: FOR PROPER OPERATION, THE SAFEPATH® PANEL SHALL BE CONNECTED TO

WARNING: CERTAIN HARDWARE FUNCTIONS ON THE SAFEPATH PANEL ARE NOT
SUPERVISED. IF ANY SUCH HARDWARE FUNCTIONS FAIL, THE SAFEPATH®
PANEL MAY NOT PROVIDE THE INTENDED WARNING AND/OR NOT INDICATE A
TROUBLE CONDITION. THE FOLLOWING ARE NOT SUPERVISED:
1. THE "SHORT CIRCUIT" DETECTION CIRCUITRY FOR ANYONE OR ALL OF
THE EIGHT CONTACT INPUTS.
THE FOLLOWING HARDWARE FAILURES WOULD PREVENT THE SAFEPATH
PANEL FROM INDICATING A TROUBLE CONDITION:
1. THE "OPEN CIRCUIT" DETECTION CIRCUITRY FOR ANY ONE OR ALL OF THE
EIGHT CONTACT INPUTS.
2. THE AUDIO SUPERVISION CIRCUITRY FOR EACH OF THE
TWO OUTPUT
CHANNELS.
3. THE STATUS CONTACT.
THESE HARDWARE FUNCTIONS SHALL BE PERIODICALLY CHECKED FOR
PROPER OPERATION.
Section 1-3 - Compliance with Applicable Codes, Regulations, Laws,
Standards, and Guidelines
COMPLY WITH ALL OF THE LATEST APPLICABLE CODES, REGULATIONS, LAWS, STANDARDS,
AND GUIDELINES.
WARNING: FOR EMERGENCY, HAZARDOUS, SECURITY, LIFE SAFETY, AND FIRE
PROTECTIVE SIGNALING SYSTEM APPLICATIONS USING THE SAFEPATH
PANEL INSTALLATION, TESTING AND MAINTENANCE SHALL BE PERFORMED
BY QUALIFIED PERSONNEL IN ACCORDANCE WITH ALL THE LATEST
NATIONAL FIRE PROTECTION ASSOCIATION (NFPA), UNDERWRITER’S
LABORATORY (UL), NATIONAL ELECTRIC CODE (NEC), OCCUPATIONAL
SAFETY AND HEALTH ADMINISTRATION (OSHA), STATE, COUNTY, LOCAL,
PROVINCE, DISTRICT, FEDERAL, AND OTHER APPLICABLE BUILDING AND
FIRE STANDARDS, GUIDELINES, REGULATIONS, LAWS, AND CODES
INCLUDING, BUT NOT LIMITED TO, ALL APPENDICES AND AMENDMENTS AND
REQUIREMENTS OF THE LOCAL AUTHORITY HAVING JURISDICTION (AHJ).
It is recommended that the local AHJ inspect and approve the proposed placement of all the notification
appliances.
Section 1-4 - Property Insurance Recommendation
The SAFEPATH® Panel is not a substitute for insurance. All users should have adequate levels of life and
property insurance.
1-2
Section 1-5 - Audio Output Considerations
WARNING: AUDIBLE SIGNALS MAY MASK MEDICAL EQUIPMENT MONITORING ALARMS.
WHERE MEDICAL EQUIPMENT MONITORING ALARMS ARE IN USE, DO NOT
USE AUDIBLE SIGNALS; PROVIDE VISUAL NOTIFICATION APPLIANCES IN
HIGHLY VISIBLE LOCATIONS.
CAUTION: The output of the audio system may not be heard in all cases. Sound can be blocked
or reduced by walls, doors, carpeting, wall coverings, furniture, insulation, bed
coverings, and other obstacles that may temporarily or permanently impede the output
of the audio system. Sound is also reduced by distance and masked by background
noise. The output of the audio system may not be sufficient to alert all occupants,
especially those who are asleep, those who are hearing-impaired, those who are
wearing devices that plug or cover the ears, and those who have recently used drugs
or alcohol. The output of the audio system may not be heard by an alert person if the
output device is placed in an area which is isolated by a closed door, or is located on a
different floor from the person in a hazardous situation or is placed too far away to be
heard over ambient noise such as, but not limited to, running water, traffic, air
conditioners, machinery or musical appliances.
If live microphone announcements, audible tones and/or voice messages cannot be readily heard and
understood clearly within the protected areas as intended, it will be necessary to increase the number
and/or sound output intensity of speakers within those areas so that they are heard and understood
clearly when activated.
Section 1-6 - RF Interference
The SAFEPATH® Panel has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at owners expense.
Section 1-7 - General
Each manufacturer's fire alarm control panel, and notification appliances operate differently and have
different features. Before specifying, installing, operating, testing, maintaining or servicing a system,
carefully read the installation, operation and testing manual for each piece of equipment and applicable
codes.
Additional copies of this manual may be obtained from:

Chapter 3 - Installation and Setup
Section 3-1 - Introduction
The lives of people depend upon the safe and proper installation of the SAFEPATH® Panel. Please read,
understand and carefully follow the specific installation instructions set forth below to avoid damage to the
SAFEPATH® Panel and equipment connected to it. Only qualified personnel in accordance with the
procedures in this manual should conduct installation.
WARNING: SHUT OFF ALL POWER BEFORE STARTING THE INSTALLATION. ELECTRICAL
SHOCK CAN CAUSE DEATH OR SERIOUS INJURY.
WARNING: DO NOT CONNECT AC POWER OR BATTERY BACKUP POWER UNTIL SYSTEM
WIRING HAS BEEN CONNECTED, MODULES HAVE BEEN INSTALLED, AND
FIELD WIRING HAS BEEN INSPECTED.
CAUTION: The SAFEPATH® printed circuit boards are sensitive to static electricity and have
delicate components mounted on them. Before handling either a board or any
component on a board, discharge any static electricity from your body by touching
a grounded object such as a metal screw, which is connected to earth, ground.
Handle the board by its edges, and be careful not to twist or flex it. The
SAFEPATH® Panel is to be installed in a static free area and the user is to properly
attach grounded wrist straps before touching any static sensitive areas. After
handling SAFEPATH® printed circuit boards, verify that the printed circuit boards
are undamaged and functioning properly.
The installer, prior to installation should consult with the authorities having jurisdiction
(AHJ).
Section 3-2 - Fire Alarm Control Panel Interface Wiring Applications
The SAFEPATH® Panel can be connected to either the FACP alarm output dry contact or to the
FACP Notification Appliance Circuit (NAC). If it is connected to the NAC, then the Notification
Appliance Circuit Interface Module (NACIM) shall be used. Follow the NACIM instruction sheet
(P83478) for proper mounting and wiring.
The SAFEPATH® Panel may be connected to either a “silenceable” or “non-silenceable” notification
appliance circuit depending upon system requirements. When the SAFEPATH® Panel is connected to
a “silenceable” NAC circuit on the FACP, activating the FACP’s alarm silence switch will silence it.
The Strobe NAC circuit on the SAFEPATH® Panel will also be silenced. In order for the strobes to
remain in alarm when the audible is silenced, the Strobe NAC circuit must be connected to a “nonsilenceable” NAC circuit on the FACP.
A SAFEPATH® Panel connected to a “non-silenceable” NAC circuit cannot be silenced from the
FACP.
“TROUBLE”, Form C relay terminals are available for monitoring the condition of the SAFEPATH®
Panel at the FACP.

Section 3-4 – Prepare a System Wiring Diagram
Wiring Guidelines
Although the SAFEPATH Panel products incorporate signal verification and noise filtering circuitry on
their inputs, induced voltages or noise on the input wiring can cause improper operation. Therefore, use
shielded twisted pair wire for all dry contact input wiring.
The shield of each cable should be connected only at one end. Each shield of each cable that
connects to the SAFEPATH Panel is to be connected to the grounding points provided near the
knockout locations on the chassis (see Figure 3-17 on Page 3-15).
The National Electrical Code (NFPA-70) defines two types of circuits for protective signaling systems:
power limited circuits and non-power limited circuits. The SAFEPATH® Panel circuits are non-power
limited.
WARNING: ALL SAFEPATH® PANEL DRY CONTACT INPUT WIRING AND AUDIO WIRING
SHOULD BE ROUTED AWAY FROM ANY HIGH VOLYAGE OR HIGH CURRENT
WIRING (SUCH AS AC OR DC POWER WIRING, AUDIO POWER WIRING, AND
MOTOR OR RELAY ACTUATION WIRING). DRY CONTACT INPUT WIRING SHALL
BE INSTALLED IN SEPARATE CONDUIT. FAILURE TO DO SO MAY CAUSE
ELECTRICAL SHOCK RESULTING IN PROPERTY DAMAGE AND SERIOUS
INJURY OR DEATH TO YOU AND/OR OTHERS.
3-4
CAUTION: The National Electric Code limits the maximum number of conductors that can be
installed in conduit and wiring boxes depending on the size of the conduit, the volume
of the boxes, and the gauge of the wire used. Make sure that wiring used for
SAFEPATH® Panel installation complies with the latest NEC, NFPA, Local, State,
County or Province requirements.
Field Wiring Connections
All SAFEPATH® Panel wiring terminals are designed to accept #12 AWG through #22 AWG wiring (one
wire per terminal). Proper wire gage considerations for the NAC Circuit must take into account current
requirements versus length of run.
Prepare System Wiring Diagram.
1. Prepare a system-wiring diagram to include all Notification Appliances, ancillary equipment, and
internal connections and power sources as required.
Visual Notification Appliance Output Wiring
Available alarm strobe current is a maximum of 2 Amps at 24VDC. Table 3-1 shows available strobe
current using the standard calculation for a Temporal Code 3 signal. The SAFEPATH® Panel does
not include any optional modules. Complete calculation information for other configurations is located
in Section 3-8 Backup Battery Calculations.
Wire gauge may vary for each visual notification appliance output circuit on the panel. Wire gauge
selection should involve consideration of all factors including, wire loop length, maximum current draw of
each appliance, number of appliances, and maximum voltage drop allowable.

Central Amplified Speaker Notification Appliance Output Wiring
The audio alarm current of the amplifier module depends on the number of speakers on the circuit, length
and gauge of wire of the audio circuit, and the audio mode in use.
When laying out each NAC circuit for the speakers, calculate the total wattage required. A good
engineering practice is to not exceed 85% of the amplifier rating that you plan to use. If your calculations
exceed this, an amplifier having increased power capacity is required or replacing the entire SAFEPATH®
Panel with greater capacity.
Wire gauge may vary for each audio appliance output on the panel. When:
•
Speaker (with transformer) appliances are used with supervised audio amplifier module
(central amplified outputs). Wire gauge selection should involve consideration of all
factors including, wire length, appliance power ratings, and the number of appliances.

•
The central amplified output is either a selectable 25, 70.7 or a 100 volt audio output,
rated for 40, or 80 watts maximum, depending upon the amplifier and its configuration.
The output meets Class B supervision requirements for notification appliance circuits.
Each output circuit shall have a UL LISTED, 10K Ohm, 1W EOLR installed across the
last audio notification appliance. If the output is unused, it shall have a UL LISTED, 10K
Ohm, 1W EOLR across the output terminals. Each amplifier module contains the required

WARNING: ALL PROTECTIVE SIGNALING SYSTEMS REQUIRE PERIODIC TESTING. ALL
PROTECTIVE SIGNALING SYSTEM EQUIPMENT SHALL BE TESTED BY
QUALIFIED PERSONNEL AT LEAST TWICE A YEAR FOR PROPER
OPERATION, OR MORE OFTEN IF REQUIRED BY CODES, REGULATIONS
AND LAWS. FAILURE TO MAINTAIN AND TEST PROTECTIVE SIGNALING
SYSTEM EQUIPMENT CAN RESULT IN NOT DETECTING EQUIPMENT
FAILURE THAT CAN CAUSE PROPERTY DAMAGE AND SERIOUS
PERSONAL INJURY OR DEATH TO YOU AND/OR OTHERS DURING AN
EMERGENCY SITUATION.
Section 3-7 – Ground Fault Detection Sensitivity Adjustment
Ground fault detection sensitivity can be adjusted for a set point between 40K Ohms and 500K Ohms.
Selecting a high resistance set point will increase the circuit sensitivity to ground fault conditions. A
high resistance may cause many false trouble conditions.
Selecting a low resistance will decrease the circuit sensitivity and will greatly reduce susceptibility to
false trouble conditions. The lower resistance allows for lower ground fault resistance before a ground
fault conditions occurs.
Before the sensitivity is adjusted, it is imperative to correct (clear) all trouble conditions.
NOTE:
The ground fault detection sensitivity set-point shall be the same value as the FACP.
Adjustment Procedure
1. Place "GRND FLT ENB DIP switch in the ON position (SW4, POS 1). See Figure 3-18 on Page
3-17.
2. Disconnect the wire between earth ground and the earth ground terminal on the Mother Board.
(See Figure 9-2 on Page 9-5 for location.)
3-18
3. Rotate the shaft of the Ground Fault Detection Sensitivity potentiometer (R53) fully
counterclockwise. (See Figure 9-2 on Page 9-5 for location) The potentiometer is a 12-turn
device, there will be need to rotate the shaft repeatedly. The potentiometer produces a clicking
sound when rotated beyond its end point.
4. On the Mother Board (SCMB), place a resistor with the desired set-point value (40K Ohm to 500K
Ohm, +/- 5% Tolerance) between the +24VDC terminal on TB4 and the earth ground terminal.
See Figure 3-10 on Page 3-10.
5. Slowly rotate the shaft of the Ground Fault Detection Sensitivity potentiometer clockwise. When
a ground fault is indicated by the trouble LED's, the sensitivity set-point is set correctly.
6. Disconnect the resistor used to set the sensitivity level.
7. Reconnect the wire between the earth ground terminal on the Mother Board and earth ground.
Section 3-8 - Battery Care and Backup Battery Calculations
Installation and Care of Sealed Lead Acid Batteries
Sealed lead acid batteries are designed to operate in standby service for approximately five years.
This is based upon a normal service condition where there is an ambient temperature of 20 degrees
C (68 degrees F) and batteries are completely discharged once every three months. LENGTH OF
SERVICE LIFE WILL BE DIRECTLY AFFECTED BY THE NUMBER OF DISCHARGE CYCLES,
DEPTH OF DISCHARGE, AND AMBIENT TEMPERATURE.
Use Guidelines:
Avoid installation and/or operation in close proximity to heat sources. While the operating
temperature range is 0 to 49 degrees C (32-120 degrees F), battery life will be maximized at an
ambient temperature of 20 degrees C (68 degrees F).
Batteries may generate ignitable gases. Because of this, batteries shall be installed in a wellventilated location, away from spark producing equipment.
Batteries shall not be installed in an atmosphere where organic solvents or adhesives may be
present. The batteries shall not be cleaned with oils, thinners, or similar substances. The
case and cover of the batteries are ABS plastic resin, which may suffer damage from these
chemicals.
Batteries shall not be installed in a heavy vibration or shock location.
Batteries shall have a minimum separation of ¼” between cells.
Insulated gloves shall always be worn when handling batteries.
WARNING: Batteries shall not be crushed, incinerated, or dismantled. The electrolyte
contains sulfuric acid, which can cause serious damage to eyes and skin. If
contact does occur, flush with water and seek immediate medical attention.
Batteries of different capacities, age, or manufacturer shall not be used together.
Battery Storage
Batteries which are to be stored for an extended period of time should be given a supplement charge
monthly. Batteries should never be stored in a discharged condition.
The self-discharge rate of batteries is approximately 3% per month when the storage temperature is
maintained at 20 degrees C (68 degrees F). The self-discharge rate will vary depending upon
temperature. Cooler temperatures cause the self-discharge rate to decrease. Warmer temperatures
cause the self-discharge rate to increase.
3-19
Calculating Backup Battery Requirements
A battery calculation worksheet is available at the back of this manual for assisting in calculating
battery backup.
It is necessary to calculate the current draw for battery backup requirements, The current
requirements depend on the system configuration and the optional modules installed. Battery Backup
current has two separate calculations that are added together. They are Standby Current and Alarm
Current.
CAUTION: The SAFEPATH® Power Supply generates 24VDC at a maximum of 6 Amps. The
sum of the currents from all modules, speaker circuits, and Strobe NAC circuits,
and Speaker Amp circuits (when SALL-15S are used) determine the current output
of the panel and cannot exceed 6 Amps. If the SAFEPATH® Panel output current
exceeds 6.0 amps, it is recommended that strobe circuits be routed through an
external power supply.
Standby Current
Standby current consumes the largest part of the storage battery capacity.
Table 3-4 represents the Standby Current of the Single Circuit SAFEPATH® Panel using the test
signal as the supervision signal. Standby calculations can use the appropriate value from this table.
The Single Circuit SAFEPATH® Panel Models in this table contain the Power Supply (DCPS), Digital
Voice Module (MDX-2) and the listed amplifiers.
Standby Current from any optional module used is listed in Table 3-5. These values added to the
Panel current complete the total Standby current for the panel
Model

Maximum strobe current on each amplifier in the panel is 2 Amps at24VDC.
Maximum “SPKR AMP” current on each SALL-15S Module is 2 Amps at 24VDC.
Standby Current Calculating Procedure
1. From Table 3-4, select the desired value of current from the proper model.
2. From Table 3-5, select the standby current from all modules selected for the panel and add them
to the value of Step 1. (If multiple RMS-2 Modules are used, calculate the standby current for
each one.)
3. Multiply the results of Step 2 by the number of standby hours required. (i.e. 24 or 60). Record this
value as the Standby Amp-hours.
Alarm Current
Table 3-7 lists the alarm current for each amplifier.
If no strobes are installed the strobe current is zero. If strobes are installed, add the current ratings of
the strobes.
UL alarm speaker current calculations are measured with a full SIN wave input with a maximum
output are as follows:

Alarm Current Calculating Procedure
1. Using Table 3-7, calculate the alarm current for each amplifier module installed.
2. Using Table 3-5, add up the alarm currents of all optional modules. If multiple Remote
Microphone Stations (RMS-2) are used, calculate the alarm current of just one.
3. Add together the strobe current from the amplifiers NAC circuit.
4. Total the results of Steps 1 through 3.
5. Divide Step 3 results by 12 (5 minutes of alarm) or 4 (15 minutes of alarm) and record this value
as Alarm Amp-hours.
Calculating Backup Battery Requirements
Good engineering practices recommend the total Amp-hours required for backup should not
exceed 80% of the Backup Battery capacity.
Backup Battery Calculation Procedure
1. Add the total Standby Current to the total Alarm Current.
2. Multiply Step 1 by 1.25. This is the minimum Backup Battery requirement for this Panel.
3. Record results on the battery calculation worksheet at the end of this manual.

Actions that Initiate Alarms
Section 4-2 - Operator’s Console
An operator’s console, which allows for manual override of the automatic message playing, is
provided. The operator’s console includes a microphone, a RESET pushbutton, a TROUBLE
ACKNOWLEDGE pushbutton, and a main AUTOMATIC/MANUAL switch. There are two LEDs to
indicate NORMAL for normal operation and TROUBLE for any Panel trouble condition. Opening the
enclosure door accesses the operator’s console.
Section 4-3 - Supervision
A trouble condition indicates that the supervisory functions have detected a malfunction in the panel.
When a trouble condition is detected, the panel may not be able to receive and/or remember
message requests from the control panel. The installer and/or user must make sure that any
message requests to the panel during a trouble condition are reactivated if necessary, when the
panel is returned to normal.
If a trouble condition is detected by any of the supervisory functions, the panel Form C status relay
(normally energized) will change state, the green NORMAL LED will turn “OFF”, and the amber
TROUBLE LED will turn “ON”. The status relay contact closure must be properly connected to and
used by the control panel to indicate a system trouble. At the same time an amber trouble location
LED will identify the location of the trouble condition. If a trouble condition is indicated, follow the
procedures in Chapter 7 "Troubleshooting”.
WARNING: DO NOT LEAVE THE PANEL IN A TROUBLE CONDITION AS, IT MAY NOT
PLAY WARNING MESSAGES WHICH COULD RESULT IN PROPERTY
DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS. IF
THE PANEL INDICATES A TROUBLE CONDITION:
(1) PROVIDE UL REQUIRED ALTERNATIVE SIGNALING AND
(2) HAVE QUALIFIED SERVICE PERSONS IMMEDIATELY REPLACE
UNIT(S) THAT HAVE MALFUNCTIONED.
4-1
WARNING: MESSAGES REQUESTED BEFORE AND DURING A TROUBLE CONDITION MAY
NOT BE HEARD, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS
INJURY OR DEATH TO YOU AND/OR OTHERS. IF MESSAGES REQUESTED
BEFORE AND DURING A TROUBLE CONDITION ARE STILL NECESSARY, THEY
SHOULD BE REPEATED WHEN THE SAFEPATH® PANEL IS RETURNED TO
NORMAL.
Visual Notification Appliance Output Circuit Supervision
The visual notification appliance output circuit is supervised for open and short circuits when the output is
de-energized. Output circuit supervision requires installation of the supplied UL LISTED, 10K Ohm EOLR
on the output circuit. Any sensed trouble will illuminate the “STR” LED on the amplifier module. See
Figure 7-1 on Page 7-2 for LED location.
Audio Notification Appliance Output Circuit Supervision
The audio notification appliance output circuit is supervised for open and short circuits when the output is
de-energized. The circuit is unsupervised when the output is energized. Output circuit supervision
requires installation of the supplied UL LISTED, 10K Ohm EOLR on the output circuit. Any sensed
trouble will illuminate the “SPK” LED on the amplifier module. See Figure 7-1 on Page 7-2 for LED
location.
Amplified Speaker Notification Appliance Power Output Circuit Supervision
The amplified speaker notification appliance power output circuit supervised for open and short circuits
when the output is de-energized. Output circuit supervision requires installation of the supplied UL
LISTED, 10K Ohm EOLR on the output circuit. Any sensed trouble will illuminate the “PWR” LED on the
SALL-15S module. See Figure 7-1 on Page 7-2 for LED location.
Amplifier Supervision
A supervisory tone plays through the amplifier during standby for supervision purpose. Any sensed
trouble illuminates the “AMP” LED on the amplifier module. See Figure 7-1 on Page 7-2 for LED location.
Ground Fault Supervision
The SAFEPATH® Panel supervises for ground fault conditions on field wiring that is not electrically
isolated. The supervised wiring includes contact inputs, visual NAC circuits, audio NAC circuits, amplified
speaker NAC circuits, trouble audible output circuits, remote microphone station wiring and MDX-2 wiring.
All other wiring is electrically isolated. Ground fault supervision may be enabled and disabled by switching
the ground fault enable switch on (GND FLT ENB, SW4, POS 1). See Figure 3-18 on Page 3-17.
Remote Microphone Supervision (Optional RMS-2)
The audio circuit is supervised on the Remote Microphone Station PCB.
Section 4-4 - Actions That Initiate Alarms
Table 4-1 indicates what can initiate an alarm condition and the resulting SAFEPATH Panel actions.
NOTE: The list is arranged in order of priority (e.g., number 1 in Table 4-1 supersedes number 2

Chapter 5 - Operational Procedures
Section 5-1 - Operator Instructions
The SAFEPATH® Panel provides an operator console for manually activating the panel. The operator
console includes a microphone, a green NORMAL LED, a yellow TROUBLE LED, a “RESET” momentary
switch, a TROUBLE ACKNOWLEDGE momentary switch, and a MANUAL/AUTOMATIC switch. The
operator interface allows the operator to manually override automatically playing pre-recorded messages
with live announcements or an evacuation tone, to silence internal and external trouble audibles, and to
ascertain if the panel has detected a trouble condition. The operator instructions on the dead front panel
are shown in Figure 5-1 on Page 5-3.
The TROUBLE and NORMAL LEDs identify to the operator the condition of the SAFEPATH® Panel. The
yellow TROUBLE LED will be illuminated whenever there is a trouble detected by the Panel. If no
troubles are detected, the green NORMAL LED will be illuminated.
The TROUBLE ACKNOWLEDGE push-button allows the operator to silence the trouble audibles, both
internal and external. When a trouble condition is detected, both the internal and external trouble
audibles are sounded. When the ACKNOWLEDGE push-button is depressed, the internal and external
trouble audibles will be silenced. The trouble audibles will resound for subsequent trouble conditions.
The Form C trouble output contact will remain in the trouble condition and the TROUBLE LED will remain
illuminated until all trouble conditions have been corrected.
The AUTOMATIC/MANUAL switch has two positions, manual (down) and automatic (up). When the
AUTOMATIC/MANUAL toggle switch is in the automatic position, pre-recorded messages may be
selected to play via dry contact inputs. When the AUTOMATIC/MANUAL switch is in the manual position,
pre-recorded messages will not play, the visual notification appliances are energized, and the evacuation
tone sounds.
Section 5-2 - To Make Live Announcements
From Panel
1. Hold the microphone within 2 inches of your mouth, press the push-to-talk switch and begin speaking.
From Optional Remote Microphone Station (RMS-2)

3. Attempt to play a message file. If the file plays then the digital voice module trouble indicator LED is
broken.
If, after the above procedure is completed, the trouble condition persists, the trouble condition is caused
by failed circuitry on the Digital Voice Module. There are no field correctable failed circuitry problems on
the digital voice module. Digital Voice Modules with failed circuitry shall be replaced immediately,
following the “SAFEPATH® Module Replacement Procedure”, set forth at the end of this section.
Procedure J
On the Single Circuit Mother Board (SCMB), the green NORMAL LED is “OFF”, the yellow TROUBLE
LED is “ON”, and the MDX-2 SYSTEM NORMAL LED is “OFF”, SYSTEM TROUBLE LED is “ON”, and
the TROUBLE LED is “STEADY ON”, then the digital voice module is partially or completely inoperative.
The Digital Voice Module can be rendered inoperative by:
1.
2.
3.
4.
Too low input voltage on the Digital Voice Module.
Failed audio channel on the Digital Voice Module.
Failed Message Kit (SMK or PMK)
Other failed circuitry on the Series MDX-2 or Output Channel Module (MDV-OCM).
If the error was either due to the first or third cause, the Digital Voice Module will not play
messages. If the error was due to the second cause, the Digital Voice Module might play
messages.
When the digital voice module is rendered inoperative, perform the following:
1. Verify that the input voltage is 24 ± 5VDC.
2. Attempt to play messages on all installed audio channels.
3. Remove Message Kit (SMK or PMK). If the “TROUBLE” LED on the MDX-2 goes to a 2 Blink pattern,
then the Message Kit is in error. Replace Message Kit.
There are no field correctable failed circuitry problems. Digital Voice Modules with failed circuitry shall be
replaced immediately, following the “SAFEPATH® Module Replacement Procedure”, set forth at the end
of this section.
Procedure K
On the Single Circuit Mother Board (SCMB), the green NORMAL LED is “OFF”, the yellow TROUBLE
LED is “ON”, and the MDX-2 SYSTEM NORMAL LED is “OFF”, SYSTEM TROUBLE LED is “ON”, and
the TROUBLE LED flashes a “2-blink pattern”, then a message memory EPROM error has occurred on
the MDX-2 module. A message memory EPROM error may be caused by:
1. Pre-programmed message memory EPROM's not installed into Series MDX-2 in proper order.
2. No messages programmed into message memory EPROM's.
7-10
3. Missing or improperly installed message memory EPROM's.
4. One or more of the messages were not programmed completely.
5. Failed circuitry on the MDX-2.
If the error was due to one of the first four causes, the trouble will clear automatically when the cause is
corrected. The first four causes should only occur when power is first turned on to the Series MDX-2.
When a message memory error is indicated, perform the following:
1. Verify that the preprogrammed message memory EPROM's were installed in the correct sockets on
the Series MDX-2. See Figure 9-3 on Page 9-7 for proper chip location. An EPROM must always be
installed in socket S14. If between one and two minutes of message memory is required, the first
EPROM must be installed into socket S14 and the second EPROM into socket S12.
2. Verify, at least one message is programmed into the message memory EPROM's.
3. Verify that all message memory EPROM's are inserted into their sockets properly.
4. Verify that there are no partially programmed messages on the message memory EPROM's. This can
only be done using commands on the serial port, which is located on the optional Ground Fault
Detection/Computer Interface Module.
If, after the above procedure is completed, the trouble condition persists, the trouble condition is caused
by failed circuitry on the Series MDX-2. There are no field correctable failed circuitry problems on the
Series MDX-2. Series MDX-2's with failed circuitry shall be replaced immediately, following the
Replacement Procedure, set forth at the end of this section.
Procedure L
On the Single Circuit Mother Board (SCMB), the green NORMAL LED is “OFF”, the yellow TROUBLE
LED is “ON”, and the MDX-2 SYSTEM NORMAL LED is “OFF”, SYSTEM TROUBLE LED is “ON”, and
the TROUBLE LED flashes a “4-blink pattern”, then an audio channel error has occurred. An audio
channel error may be caused by:
1. Too low an audio level while playing a message.
2. Pause in message while playing a message that lasts longer than 3 seconds.
If the error occurs while playing a file, then the error was due to the first cause. If the error occurs
immediately after turning on power to the Series MDX-2, the error was due to the second cause.
If the error was due to either cause while playing a message, the trouble will clear automatically when
audio is again detected while a message is playing. If the error is due to the third cause, the trouble will
clear automatically when the output is no longer loaded down while a message is playing. If the error was
due to the fourth cause, the trouble will clear automatically when the module is properly installed and
input power is cycled off and on.
When an audio channel error is indicated, perform the following:
1. Have the message re-recorded, shortening duration of the pause.

Section 9-2 - Single Circuit Mother Board (SCMB)
Wheelock, Inc. Part Number 108974
The Single Circuit Mother Board provides all signal handling capabilities between itself and the amplifier
modules, terminal blocks for output wiring, and connectors for handling signals from the digital voice
module.
The Single Circuit Mother Board is illustrated in Figure 9-2 on Page 9-5.
A single amplifier module is connected to the SCMB.
A single channel from the Digital Voice Module (MDX-2) is connected to the SCMB. The digital voice
module is mounted on the power supply cover and wired to the Mother Board. The digital voice module
channel will play through the amplifier module installed.
The microphone input is located in the lower right corner of the board and is used for live voice
announcements.
Form C contacts are available for remote monitoring of Alarm Status and Trouble Status. Also remote
trouble power is available at 24VDC, 0.100 Amps, that is non-supervised.
Single Circuit Mother Board supervises the Digital Voice Module (MDX-2), Power Supply, and the
amplifier module (SAA-40S, SAA-80S/SE, or SALL-15S) for proper operation. The microphone is
supervised for connection.
The channel play contacts from the digital voice module (MDX-2) are monitored to determine their status
(e.g. active or inactive). If the channel play contact is inactive, the control module routes a supervision
tone to the amplifier circuit module and monitors the amplifier for functionality. If the channel playing
contact is active, the control module routes the audio from that MDX-2 line output to the amplifier circuit
module. Wiring used to monitor the channel play contacts and to route the line output from the Digital
Voice Module is supervised for open and short circuit conditions.
The Power Supply module is supervised for two conditions: low AC input power, and low battery voltage.
The wiring between the controller module and the battery charger is supervised for open and short circuit
conditions.
The amplifier module is supervised for two failure conditions: field wiring trouble conditions and amplifier
audio output trouble conditions. The SCMB only supervises the audio output during standby conditions.
When either a message is playing from the Digital Voice Module or a live announcement is being made
from the microphone, the field wiring and audio output are not supervised.
The strobe NAC circuit can be used with standard non-synchronized strobes or the circuit can be place in
the SYNC mode for synchronizing Wheelock, Inc. synchronized strobes. Synchronization is accomplished
by turning “ON” DIP Switch SW5, Position 3 (SYNC) on the SAMB.
The strobe NAC circuit on the amplifier module is also supervised in the standby mode for field wiring
trouble conditions.
If at any time a trouble condition is detected, the SCMB will energize the internal audible, the external
trouble audible circuit, and transfer the Form C trouble contact to the trouble position, turn “OFF” the
NORMAL LED, and turn “ON” the TROUBLE LED.
There are two fuses on the Mother Board. F1 is the fuse for the external trouble audible circuit, and F2 is
the fuse for the Remote Microphone Station power. Both fuses are rated at 0.5A. See Figure 9-2 on
Page 9-5 for fuse location.

Section 9-5 - Supervised Audio System Amplifier/Signal Circuit
Module, 40 Watts (SAA-40S)
Wheelock, Inc. Part Number: 105493
The supervised audio system amplifier/signal circuit module, 40 watts (SAA) provides audio amplification
for the SAFEPATH® system. The amplifier can be selected to have either a 25V or a 70.7V audio output.
The amplifier contains a switch mode power supply, a linear amplifier, and supervision circuitry.
The switching power supply is used to provide a constant DC voltage to the amplifier while the input
voltage is allowed to fluctuate over its operating range. The amplifier amplifies the low-level 600-ohm
audio to 40 watts output at either 25V or 70.7V. The supervision circuit monitors field speaker wiring
integrity, field strobe wiring integrity, and amplifier functionality.
The module can be field configured for either 25V or 70.7V output. The configuration is done using a twoposition slide switch (S1) on the printed circuit board. One position (down) configures the amplifier to
have a 25V output and the other position (up) configures the amplifier to have a 70.7V output. See Figure
9-5 on Page 9-10 for switch location.
The amplifier supervises both the strobe field wiring and the speaker field wiring with a DC current. The
strobe field wiring is supervised with a reverse polarity technique, which applies a DC voltage with one
polarity to supervise the wiring and then reverses the polarity to energize the strobes. The speaker field
wiring is supervised with a DC current, which is removed when audio is being played. Both field-wiring
circuits are only supervised in the standby state. The amplifier is supervised by monitoring the amplifier
output for audio. The state of each of the three supervision features is indicated via three LEDs on the
module. See Figure 9-5 on Page 9-10 for LED locations.
There are two fuses on the printed circuit board, F1 and F2. Fuse F1 is the main fuse for the entire
board. F2 is the fuse for the strobe power. See Figure 9-5 on Page 9-10 for fuse locations.
Two UL LISTED 10K Ohm, 1W, End of Line Resistors are included with this module.

Wheelock, Inc. Part Number: SAA-80S 105495, SAA-80SE 105496
The supervised audio system amplifier/signal circuit module, 80 watts (SAA) provides audio amplification
for the SAFEPATH® system. The amplifier can be selected to have either a 25V or a 70.7V audio output.
The SAA-80SE (European version) is 100V audio output only. The amplifier contains a switch mode
power supply, a linear amplifier, and supervision circuitry.
The switching power supply is used to provide a constant DC voltage to the amplifier while the input
voltage is allowed to fluctuate over its operating range. The amplifier amplifies the low-level 600-ohm
audio to 80 watts output. The supervision circuit monitors field speaker wiring integrity, field strobe wiring
integrity, and amplifier functionality.
The SAA-80S module can be field configured for either 25V or 70.7V output. The configuration is done
using a two-position slide switch (S1) on the printed circuit board. One position (down) configures the
amplifier to have a 25V output and the other position (up) configures the amplifier to have a 70.7V output.
See Figure 9-6 on Page 9-12 for switch location.
The SAA-80SE module is configured for a 100V output only. The two-position slide switch is removed.
The amplifier supervises both the strobe field wiring and the speaker field wiring with a DC current. The
strobe field wiring is supervised with a reverse polarity technique, which applies a DC voltage with one
polarity to supervise the wiring and then reverses the polarity to energize the strobes. The speaker field
