BEFORE INSTALLING
Please read the System Sensor Voice Evacuation Application Guide, which
provides detailed information on speaker notification devices, wiring and spe-
cial applications. Copies of this manual are available from System Sensor.
US: NFPA 72 and NEMA guidelines should be observed. System Sensor also
recommends installing fire alarm speakers in compliance with NFPA 72,
ANSI/ UL 1480 and NEC 760. Important: The notification appliance used
must be tested and maintained following NFPA 72 requirements.
CANADA: CAN/ULC S524 guidelines should be observed. System Sensor
also recommends installing fire alarm speakers in compliance with CAN/ULC
S524 and CEC. Important: he notification appliance used must be tested and
maintained following CAN/ULC S536 requirements
GENERAL DESCRIPTION
System Sensor series of notification appliances offer a wide range of audible
and visible devices for life safety notification. Our indoor speaker strobes
come with 7 field selectable candela settings. The candela setting can be veri-
fied when the unit is installed, by looking into the small window on the front.
The strobe portion is designed to be used in 12 VDC, 24VDC, or 24V FWR
(full wave rectified) systems. The speaker is designed to be used at either 25
or 70.7 volts, and it will operate at any one of four input power levels. Our
speaker strobes are suitable for dry and damp environments. These products
are electrically backwards compatible with previous generation of System
Sensor speakers, speaker strobes, and strobes. With its low total harmonic
distortion, the System Sensor L-Series offers high fidelity sound output.
USA: Speakers Strobes are public mode notification appliances intended to
alert occupants of a life safety event. The speaker is listed to ANSI/UL 1480
(public mode) and the strobe is listed to ANSI UL 1638 (public mode).
FIRE ALARM SYSTEM CONSIDERATIONS
USA: System Sensor recommends installing fire alarm speakers in compliance
with NFPA 72, ANSI/UL 1480 and NEC 760.
Canada: System Sensor recommends installing fire alarm speakers in compli-
ance with CAN/ULC S524 and Canadian Electrical Code.

SYSTEM DESIGN
The system designer must make sure that the total current drawn by the de-
vices on the loop does not exceed the current capability of the panel supply,
and that the last device on the circuit is operated within its rated voltage. The
current draw information for making these calculations can be found in the
tables within this manual. For convenience and accuracy, use the voltage drop
calculator on the System Sensor website (www.systemsensor.com).
When calculating the voltage for the last device, it is necessary to consider
the voltage drop due to the resistance of the wire. The thicker the wire, the
smaller the voltage drop. Note that if Class A wiring is installed, the wire
length may be up to twice as long as it would be circuits that are not fault
tolerant. The total number of strobes on a single NAC must not exceed 69 for
24 volt applications.
All products meet the light output profiles specified in the appropriate UL
Standards. (See Figure 6.)
