Chapter 2: Safety Precautions
2.3 Compliance with Applicable Codes,
Regulations, Laws, Standards, and Guidelines
Comply with all of the latest applicable codes, regulations, laws, standards, and guidelines.
WARNING: Ensure that for emergency, life safety applications
using the Series SPB Audio Booster, installation, testing and
maintenance is always 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 Authority Having Jurisdiction (AHJ) inspect and approve the
proposed placement of all the notification appliances.
2.4 Property Insurance Recommendation
The Voice Evacuation System containing the SPB Series Audio Booster panel is not a substitute
for insurance. Make sure that you have adequate levels of life and property insurance.
2.5 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
Series SPB Audio Boosters Manual, Revision A

Chapter 2: Safety Precautions
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,
increase the number and/or sound output intensity of speakers within those areas
so that they are heard and understood clearly when activated.
2.6 RF Interference
The Series SPB Audio Booster 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 is required to correct the interference at his own
expense.
2.7 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.

Figure 4-9 Alarm and Trouble Connections
The Trouble relay changes state whenever a trouble condition occurs on the Audio Booster circuit
board and when the TROUBLE LED D73 lights. As shown in Figure 4-14, connecting to the
common terminal (C) and the normally open terminal (NO) would prevent current flow through
the relay contacts in the normal operating condition. A trouble condition causes the relay to
switch states, allowing current to flow. When there is no power (DC IN or BATTERY) the
common and normally open contacts are shorted.
1. If required, connect the Expansion Out. Ensure that a UL Listed 10K Ohm 1/2W EOLR
is connected for supervision.
2. Connect External Trouble circuit to the proper Trouble (TRB) connections.
3. Connect the panel to earth ground, following the National Electrical Code (NEC) and

4.6.2 Checkout Procedure
Connect AC power, then connect batteries.
NOTE: When the AC power source is applied to the panel, the battery voltage check circuitry is
activated. If batteries are not connected within 20 seconds, the panel trouble circuit activates. The
battery voltage check circuitry re-checks for batteries every two minutes. If the batteries are
installed during the two-minute period, the panel remains in trouble until the next re-check.
D11 AC LED (Green) should be “ON” to indicate normal operation.
If D73 TROUBLE LED (Yellow) is “ON,” a trouble condition is indicated. STOP TESTING.
Refer to Chapter 8 of this manual, then troubleshoot and correct the problem before you resume
testing. See Figures 8-1 and 8-2 for location of LEDs.
Perform the following tests:
4.6.2.A Strobe Circuit Test (SPB-80/4 Only)
1. Switch SW2 to the CC position (depressed to the bottom).
2. Short the STB IN terminals. The Strobe Output Circuit should flash. Red LEDs D70
STB1 OUT and D57 STB2 OUT are lighted. Remove the short.
4.6.2.B Audio Output Test
Play a digital message or use the built-in microphone on the SP40S voice evacuation panel and
test the audio output circuit(s).
WARNING: Perform mandatory testing of all protective
signaling systems as required. Test all protective signaling system
equipment using 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 serious
personal injury or death to you and/or others during an emergency
situation.
4.7 Ground Fault Detection
Ground fault detection sensitivity is 600K Ohms for Class B, Style Y connections.
NOTE: The Ground Fault LED D34 may flicker while STB-IN is operated in Cooper Wheelock
Pass-Through Mode (JP5 removed). This DOES NOT indicate the presence of an actual Ground
Fault Trouble.

Chapter 4: Installation
4.8 Battery Care and Backup Battery Calculations
4.8.1 Caring for 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 is 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 is maximized at an
ambient temperature of 20 degrees C (68 degrees F).
Batteries may generate ignitable gases. Because of this, install batteries in a well-ventilated
location, away from spark producing equipment.
DO NOT install batteries in an atmosphere where organic solvents or adhesives may be present.
DO NOT clean the batteries with oils, thinners, or similar substances. The case and cover of the
batteries are ABS plastic resin, which may suffer damage from these chemicals.
DO NOT install batteries in a heavy vibration or shock location.
ALWAYS wear insulated gloves when handling batteries.
DO NOT use together batteries of different capacities, age, or manufacture.
WARNING: DO NOT crush, incinerate, or dismantle batteries.
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.
4.8.2 Storing Batteries
For batteries that are to be stored for an extended period of time, give a supplement charge
monthly.
NEVER store batteries 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 varies depending upon
temperature. Cooler temperatures cause the self-discharge rate to decrease. Warmer temperatures
cause the self-discharge rate to increase.
Series SPB Audio Boosters Manual, Revision A

Chapter 4: Installation
4.8.3 Calculating Backup Battery Requirements
A Worksheet for assisting in calculating batteries is available in Chapter 11.
Due to the current drain on the battery, the maximum battery size for the Series SPB Audio
Booster SPB-80/4 and SPB-160 is 33Ah. For the SPB-320, each SPB-160 has its own backup
batteries. The enclosure can accommodate up to 12Ah. Larger batteries may necessitate a
separate battery box.
It is necessary to calculate the current draw for batteries requirement. The current requirement
depends on the system configuration and the appliances connected to the speaker output circuits.
Batteries current has two separate calculations that are added together: Standby Current and
Alarm Current.
4.8.3.A Standby Current
The standby current consumes the largest part of the storage battery capacity. The standby current
of the Series Audio Booster panel is 0.120 Amps.
1. If splitters are used, calculate the amount of standby current used by the splitters and add
it to the Audio Booster’s standby current.
2. Multiply this value by the number of standby hours required. Normally this is 24 hours.
This represents the total Standby Capacity Required in Amp-Hours for the panel.
4.8.3.B Alarm Current
The maximum alarm current for the Series SPB Booster panel is 10.1 Amps (9.6 Amps for audio,
0.50 Amps for auxiliary power).
1. Calculate strobe output current by adding the current draw of all strobes. Current draw is
in Amps.
2. Calculate speaker output current by totaling all the speaker wattage settings. Multiply the
sum by 0.054. The result is the current draw in Amps.
3. Add the strobe current, the speaker current, and auxiliary current together. The result is
the total alarm current in Amps.
4. To operate for 5 minutes of alarm on battery power, multiply Step 2 by 0.083 hrs. To
operate for 15 minutes of alarm on battery power, multiply Step 3 by 0.25 hrs. The result
is the total alarm Capacity Required in Amp-Hours.
4.8.3.C Battery Calculations
Good engineering practices recommend the total Amp-hours required for backup should
not exceed 90% of the Backup Battery capacity. The Audio Booster has been UL approved
for up to 33Ah batteries.
1. Add the total Standby Capacity Required to the total Alarm Capacity Required.
2. Multiply Step 1 by 1.1. This is the minimum Backup Battery requirement for this panel.
3. Record results on worksheet.

5.1 Introduction
This chapter describes the operating characteristics of the Series SPB Audio Booster Panel.
Included is information about the following panel features:
Supervision
Audio Notification Appliance Output Circuit Supervision
Amplifier Supervision
Actions that Initiate Alarms
5.2 Supervision
A TROUBLE LED 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 broadcast
messages from the host voice evacuation panel.
If a trouble condition is detected by any of the supervisory functions, the internal sounder of the
SP40S voice evacuation panel operates, the audio booster Form “C” TROUBLE relay (normally
energized) changes state, and the yellow TROUBLE LED turns “ON.” The Trouble Status Relay
may be used to provide an external audible or visual alert to indicate that the audio booster is in a
trouble condition. At the same time, one of the yellow trouble location LEDs identifies the
location of the trouble condition. If a trouble condition is indicated, follow the procedures in
Chapter 8 "Troubleshooting.”
WARNING: Do not leave the panel in a trouble condition, as it
may not play warning messages from the voice evacuation panel,
which could result in 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.
WARNING: Messages requested before and during a trouble
condition may not be heard, which could result in 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 panel is returned to normal.
Series SPB Audio Boosters Manual, Revision A

Chapter 5: Operation
5.1.1 Audio Notification Appliance Output Circuit Supervision
The SPB-80/4 has one 80-watt circuit, while the SPB-160 has two 80-watt circuits. The SPB-320
has four 80-watt circuits. The audio notification appliance output circuit uses Class B, Style Y
wiring, and is supervised for open and short circuits. Output circuit supervision requires
installation of UL Listed 10K Ohm, 1/2W EOLR on the output circuit. A sensed open circuit
trouble will illuminate D18 for AUD2 and D30 for AUD1 audio open LED. See Figures 8-1 and
8-2 for LED location.
5.1.2 Visual Notification Appliance Output Circuit Supervision
(SPB-80/4 only)
The SPB-80/4 has two 2-amp visual notifications circuits. The visual notification appliance
output circuit on the SPB-80/4 uses Class B, Style Y wiring, and is supervised for open and short
circuits. Output circuit supervision requires installation of UL Listed 10K Ohm, 1/2W EOLR on
the output circuit. A sensed strobe open circuit trouble illuminates D53 for STB1, D69 for STB2.
See Figure 8-1.
5.1.3 Amplifier Supervision
A supervisory tone plays through the amplifier section during standby for supervision purpose.
Any sensed trouble illuminates D77 “AMP” LED indicator. See Figure 8-2 for the SPB-160 for
LED indicator location.
5.1.4 Ground Fault Supervision
The panel supervises for ground fault conditions on Class B, Style Y field wiring that is not
electrically isolated. The supervised wiring includes contact inputs and audio NAC circuit
outputs. All other wiring is electrically isolated. If a ground fault condition exists, D100 GF LED
indicator illuminates. See Figures 8-1 and 8-2 for LED indicator location.
5.2 Actions that Initiate Alarms
A 1V, 25V, or 70.7V input from a voice evacuation panel initiates the voice output. On the SPB80/4, a selection of either a 8-33 VDC NAC input or a contact closure connected to the strobe
input activates the two 24VDC, 2A strobe output circuits.
