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.
Section 1-5 - Audio Output Considerations
! Warning:
! Caution:
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.
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.
1-3
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 the user’s own
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

Chapter 3 - Installation and Setup
Section 3-1 - Introduction
The lives of people depend upon your 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.
OFF ALL POWER BEFORE STARTING THE INSTALLATION.
! Warning: SHUT
ELECTRICAL SHOCK CAN CAUSE DEATH OR SERIOUS INJURY.
NOT CONNECT AC POWER OR BATTERY BACKUP POWER UNTIL
! Warning: DO
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 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) must 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 “non-silenceable” NAC circuit on the FACP instead of to the SAFEPATH®
Panel.
A Panel connected to a “non-silenceable” NAC circuit cannot be silenced.
“TROUBLE”, Form “C” relay terminals are available for monitoring the condition of the
SAFEPATH® Panel.

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 3-16).
All input and output circuits on the Dual-Circuit SAFEPATH® Panel are considered non-power
limited circuits. Power limited wiring within the SAFEPATH® Panel must have a 1/4” separation.
! Warning:
ALL SAFEPATH® PANEL DRY CONTACT INPUT WIRING AND AUDIO
WIRING SHOULD BE ROUTED AWAY FROM ANY HIGH VOLTAGE OR
HIGH CURRENT WIRING (SUCH AS AC OR DC WIRING, AUDIO POWER
WIRING, AND MOTOR OR RELAY ACTUATION WIRING). DRY CONTACT
WIRING SHOULD BE INSTALLED IN SEPARATE CONDUIT FROM THESE
WIRINGS. FAILURE TO DO SO MAY CAUSE LELECTRICAL SHOCK
RESULTING IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH
TO YOU AND /OR OTHERS.
! 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 Notification 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.
THE MAXIMUM CURRENT OUTPUT OF THE DUAL-CIRCUIT SAFEPATH® PANEL 24VDC
POWER SUPPLY IS 6 AMPS.
Visual Notification Appliance Output Wiring
Available alarm strobe current varies depending on the amount of alarm current used by the
Dual-Circuit SAFEPATH® Panel modules without the strobe function. The audio alarm current of
the amplifier module(s) depends on the number of speakers on the circuit, length and gauge of
wire of the audio circuit, and the audio mode in use. Table 3-1 shows available strobe current for
each model using the standard calculation for a Temporal Code 3 signal. The SAFEPATH® Panel
3-5
does not include any optional modules. The maximum strobe output on each amplifier
module is 2 Amps. Complete calculation information for other configurations is located in
Section 3-7 – Backup Battery Calculations.

Note 2: A maximum of 4.6 Amps is available for a combination of Speaker Power and Strobe currents.
Note 3: A maximum of 5.5 Amps is available for a combination of Speaker Power and Strobe currents.
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.
When laying out each NAC circuit for the speakers, calculate the total wattage required. Good
engineering practice is to not exceed 85% of the amplifier rating that you plan to use. If calculations
exceed this, an larger capacity amplifier or additional amplifier(s) can solve this problem.

Section 3-7 - 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 of ¼” separation 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.
3-23
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.
Calculating Backup Battery Requirements
It is necessary to calculate the current draw for battery backup requirement, 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 24 VDC 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.
Backup Battery Worksheet
Worksheet for assisting in calculating battery backup is available as Appendix B.
Standby Current
Standby current consumes the largest part of the storage battery capacity. Table 3-4 represents
the Standby Current of the Dual-Circuit SAFEPATH® Panel using the test signal as the
supervision signal. Standby calculations can use the appropriate value from this table. The DualCircuit 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 on Page 3-26. These values
added to the Panel current complete the total Standby current for the panel
Standby Current Calculating Procedure
1. From Table 3-4 on Page 3-25, select the desired value of current from the proper Model.
2. From Table 3-5 on Page 3-26, select the standby current from all modules selected for the
panel and add them to the value of Step 1. (If multiple RMS-3, SPL and/or NACIM 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.

Table 3-5 lists the alarm current of the Dual-Circuit SAFEPATH® Modules. Table 3-7 on Page 327 lists the alarm current for each amplifier. If no amplifiers are installed in the amplifier slot the
current for that slot is zero.
If no strobes are installed in the zone, the current is zero. If strobes are installed, add the sum of
the current ratings of the strobe in each circuit to the corresponding amplifier.
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 on Page 3-27, 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 RMS-3 with
an AIM-3, calculate the alarm current for one. If SPL and/or NACIM Modules are used,
calculate the alarm current for each one.
3. Add together the strobe current from both amplifier NAC circuits.
4. Total the results of Steps 1 through 3.

Chapter 4 - OPERATION
Section 4-1- Introduction
This chapter describes the operating characteristics of the SAFEPATH® Panel. Included is
information about the following SAFEPATH® Panel features:
Operator's Console
Supervision
Visual Notification Appliance Output Circuit Supervision
Audio Notification Appliance Output Circuit Supervision
Amplified Speaker Notification Appliance Power Output Supervision
Amplifier Supervision
Remote Microphone Station Supervision (Optional RMS-3)
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, a main “AUTOMATIC/MANUAL” switch, an “ALL-CALL ON/OFF”
switch, two “Zone” select switches, and “NORMAL”, “TROUBLE”, Zone ”SELECT”, Zone
“ALARM” and an all-call “SELECT” LEDs. Opening the enclosure door accesses the operator’s
console. See Figure 5-1 on Page 5-3 for front panel layout.
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 returns 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
SAFEPATH® Panel is in Standby mode. Output circuit supervision requires installation of the
supplied UL LISTED, 10K Ohm EOLR resistor on the NAC circuit. Any sensed trouble will
illuminate the “STR” LED on the amplifier module. See Figure 3-18 for LED location.
Audio Notification Appliance Output Circuit Supervision
The audio notification appliance output circuit is supervised for open and short circuits when the
SAFEPATH® Panel is in Standby mode. Output circuit supervision requires installation of the
supplied UL LISTED, 10K Ohm EOLR resistor on the output circuit. Any sensed trouble will
illuminate the “SPK” LED on the amplifier module. See Figure 3-18 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 SAFEPATH® Panel is in Standby mode. Output circuit supervision requires installation of
the supplied UL LISTED, 10K Ohm EOLR resistor on the output circuit. Any sensed trouble will
illuminate the “PWR” LED on the SALL-15S module. See Figure 3-18 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 3-18 for LED
location.

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” push button, a “TROUBLE ACKNOWLEDGE” push-button switch, a
“MANUAL/AUTOMATIC” switch, an “ALL-CALL” switch, “ZONE 1”, and “ZONE 2” switches. 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 console
instructions located on the dead front panel and 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 “MANUAL/AUTOMATIC” switch has two positions, manual (down) and automatic (up).
When the “MANUAL/AUTOMATIC” toggle switch is in the automatic position, pre-recorded
messages may be selected to play on individual circuits via dry contact inputs. When the
“MANUAL/AUTOMATIC” switch is in the manual position, pre-recorded messages will not play,
the visual notification appliances are energized, and the evacuation tone sounds on all circuits.
NOTE: When a dry contact closure occurs on any programmed input (IN1 through IN8), the
“ALL CALL”, “ZONE 1”, and “ZONE 2” switches have no control over the output
unless the live microphone is used. Live microphone is the highest priority,
messaging source and overrides dry contact inputs.
The “ALL-CALL” switch overrides “ZONE 1” and “ZONE 2” switch positions allowing
audible signals to be heard regardless of the position of these switches.
The “ZONE 1” and “ZONE 2” on/off switches are used to select zones for live audible from
the microphone. When a zone is switched “ON” the respective strobe circuit is also
energized.

TROUBLE LED is “ON”, and the TROUBLE LED flashes a “4-blink” pattern, 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.
7-13
3. The optional Output Channel Module for channel two is not installed or is improperly installed.
The number of output channels installed must agree with the number of output channels used in
the Programmed Message Kit (PMK). The Standard Message Kit (SMK) is always
programmed for single channel output.
4. Failed audio channel on Series MDX-2 or an optional Output Channel Module.
If the error occurs while playing a file, the error was due to one of the first three possible causes.
If the error occurs immediately after turning on power to the Series MDX-2, the error was due to
the last possible cause.
If the error was due to the first or second 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.
2. Verify that the optional Output Channel Module is installed properly.
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 or Output Channel Module (MDV-OCM) and these components if
defective shall be replaced immediately following Section 7-1 - SAFEPATH® Module
Replacement Procedure on Page 7-14.

Section 9-2 - Dual-Circuit System Mother Board (DCMB)
Wheelock, Inc. Part Number: 107372
The Dual-Circuit System Mother board (DCMB) provides all signal handling capabilities between
the DCDC and the amplifier modules, terminal blocks for output wiring, and connectors for
handling signals between the DCDC and the digital voice module.
The DCMB is illustrated in Figure 9-2 on Page 9-4
Up to two amplifier modules may be connected to the DCMB. The amplifier modules may be
installed in any order in slots 1 and 2. Installing an amplifier module in slot 1 and 2 will result in
the module’s output appearing in the correspondingly numbered terminal block (labeled “Zone 1”
and “Zone 2”). For example, when an amplifier module is installed in slot 1, the amplifier
module’s output appears at the terminal block labeled “Zone 1”.
Up to 2 channels from the Digital Voice Module (MDX-2) may be connected to the DCMB. The
digital voice module is inserted into J5. The digital voice module channel will play through Zone 1
and Zone 2 if amplifier modules are installed.
IN1 through IN8 are the dry contact inputs used to trigger the automatic alarm circuits. With the
MDX-2 Module installed, IN1 through IN8 provide access to as many as 8 programmed
messages on the MDX-2.
If the MDX-2 is not used and the Shunt PCB is used, IN1 initiates Zone 1 and IN2 initiates Zone
2. IN3 through IN8 are not used.
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 24 VDC, 0.100 Amps that is non-supervised.

Dual-Circuit SAFEPATH® Motherboard (DCMB)

Section 9-3 - Dual-Circuit Control Module (DCDC)
Wheelock, Inc. Part Number: 107373
The Dual-Circuit Control Module (DCDC) provides all of the control capabilities for the
SAFEPATH® panel. The controller module supervises the Digital Voice Module (MDX-2), DualCircuit Power Supply (DCPS), and amplifier modules (SAA-40S, SAA-80S/SE, and SALL-15S) for
proper operation. The microphone is supervised for connection.
The channel playing contacts from the digital voice module (MDX-2) are monitored to determine
their status (e.g. active or inactive). If the channel playing contact is inactive, the control module
routes a supervision tone to each of the amplifier circuit modules and monitors the amplifier for
functionality. If the channel playing contact is active, the control module routes the audio from
that channel’s line output from the digital voice module to the respective amplifier circuit module.
Wiring used to monitor the channel playing contacts and to route the line outputs from the digital
voice module is supervised for open and short circuit conditions.
The DCPS module is supervised for three conditions: low AC input power, battery wiring trouble,
and battery voltage low. The wiring between the controller module and the battery charger is
supervised for open and short circuit conditions.
The amplifier modules are supervised for two failure conditions: field wiring trouble conditions and
amplifier audio output trouble conditions. The controller module 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.
If at any time a trouble condition is detected, the controller module will energize the internal
audible and the external trouble audible circuit transfer the Form C trouble contact to the trouble
position, turn off the “NORMAL” indicator, and turn on the “TROUBLE” indicator.
Synchronized signal for the Strobe NAC circuits can be energized by turning ON DIP switch SS.
This will cause the Wheelock Synchronized Strobes to flash at the same time.
Other controls from the DIP Switches are, Remote Microphone ON/OFF (RM), and selection of
supervisory tone from the built in tone generator (T1, T2, T3).
There are two 0.5A fuses on the printed circuit board. F1 is the fuse for Remote Microphone
power, and F2 is the fuse for the external trouble audible. See Figure 9-3 on Page 9-6 for fuse
location.

Section 9-4 - Digital Voice Module (MDX-2)
Wheelock, Inc. Part Number: 105094
The Digital Voice Module (MDX-2) is a plug-in module that provides playback capability of prerecorded messages. The MDX-2, when activated, provides a pre-recorded tone and/or message
to the Dual-Circuit SAFEPATH® Panel which then broadcasts it through the amplifiers and to the
audio appliances.
The MDX-2 can have up to 8 pre-recorded messages that can be initiated by dry contact closure
or open collector for each one. Figure 9-4 on Page 9-8shows the location of these inputs. Up to 2
minutes of audio storage are recorded on UV-erasable EPROM memory chips. Any dry contact
closure or open collector can include Acknowledgment of the playing file and Reset initiation.
(The reset switch is required to be in a locked enclosure.)
The memory chips are normally recorded at Wheelock, Inc. The Standard Message Kit (SMK)
which has 8 common messages and tones, is programmed for a single channel output. Jumper
wires are in place on the MDX-2 so the same message will play on both channels. The
Programmed Message Kit (PMK) is tailor made to the customer’s desires including separate
messages on the two channels. The location of these kits are shown in Figure 9-4 on Page 9-8
The MDX-2 has a maximum of two line-level outputs that can play two different messages, one to
each amplifier, simultaneously. This is done by installing an Output Channel Module (AM-MDVOCM), Wheelock, Inc. Part Number 105097 on the MDX-2 Module.
The MDX-2 for the Dual-Circuit SAFEPATH® Panel is configured for the same message to be
transmitted on both amplifier modules. This is done with the jumper wires in the upper right hand
corner shown in Figure 9-4 on Page 9-8.
The Standard Message Kit (SMK) has a variety of configurations. Consult the current Wheelock,
Inc. Catalog for the up to date configurations.

Section 9-6 - SAA-40S (Supervised Audio System Amplifier/Signal Circuit
Module, 40 Watts)
Wheelock, Inc. Part Number: 105493
The SAA-40S is a supervised audio system amplifier/strobe circuit module. It is capable of
providing 40 watts of audio amplification and a 24V, 2.0 Amp strobe NAC circuit for the
SAFEPATH® Panel. The amplifier section can select either a 25V or a 70.7V audio output. The
amplifier contains a switch mode power supply, a linear amplifier, and supervision circuitry.
The switch mode 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 board 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. The down position configures the
amplifier for a 25V output and the up position configures the amplifier for a 70.7V output. See
Figure 9-6 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 printed circuit board. See Figure 9-6 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 9-6 on Page 9-11 for fuse locations.
Two UL LISTED 10K Ohm, 1W EOLR Resistors are included.

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® Panel. The amplifier can be selected to have either a 25V or a
70.7V audio output. The SAA-80SE (Export version) has only a 100V audio output. The amplifier
contains a switch mode power supply, a linear amplifier, and supervision circuitry.
The switch mode 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 board of the SAA-80S 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. The
down position configures the amplifier to have a 25V audio output and in the up position
configures the amplifier to have a 70.7V audio output. See Figure 9-7 on Page 9-13for switch
location.
The board of the SAA-80SE 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 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 printed circuit board. See Figure 9-7 on

The module supervises the strobe NAC circuit field wiring, the speaker amplifier audio field wiring,
the speaker amplifier power NAC circuit field wiring, and the amplifier. The strobe NAC circuit
field wiring and the speaker amplifier power wiring are 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 strobe NAC circuit. The speaker amplifier audio NAC circuit field
wiring is supervised with a DC current, which is removed when audio is being played. Both fieldwiring circuits are only supervised in the standby condition. The amplifier is supervised by
monitoring the amplifier output for audio. The state of each of the four supervision features is
indicated via four LEDs on the printed circuit board. See Figure 9-8 on Page 9-15 for LED
locations.
There are three fuses on the printed circuit board, F1 and F2, and F3. Fuse F1 is the fuse for the
