BEFORE INSTALLING
Please read the System Sensor Voice Evacuation
Application Guide, which provides detailed information on speaker notification devices, wiring
and special applications. Copies of this manual are
available from System Sensor. NFPA 72, CAN/ULC
S524 and NEMA guidelines should be observed.
Important: The notification appliance used must be
tested and maintained following NFPA 72 requirements.
GENERAL DESCRIPTION
System Sensor series of notification appliances offer
a wide range of audible and visible devices for life
safety notification. The SPCW8 speaker is designed
to be used at either 25 or 70.7 volts, with field selectable tap settings from ⅛ to 8 Watts. These products are designed for high efficiency sound output
with low total harmonic distortion to offer high fidelity sound output.
Its clear audibility is designed to meet life safety
needs from fire to emergency communication messages. With its wide frequency range it can also
be used for general signaling such as paging and
background music. The SPCW8 speaker is listed
1 I56-0005-000R
05-20
400 – 4000 Hz (Fire Alarm)
200Hz – 15KHz (General Signaling)
to ANSI/UL 1480, CAN/ULC S541 and CSA C22.2
No. 205 requirements for public mode and general
signaling applications as well as ANSI/UL 2043 plenum rated. Speaker is suitable for indoor and damp
installations.
FIRE ALARM SYSTEM CONSIDERATIONS
All wiring must be installed in compliance with the
National Electrical Code (NEC , Canadian Electrical Code) and applicable local codes. System Sensor
recommends installing fire alarm speakers in compliance with NFPA 72, ANSI/UL 1480 , CAN/ULC
S524 and NEC 760.
WIRING AND MOUNTING
All wiring must be installed in compliance with the
National Electric Code and the local codes as well as
the authority having jurisdiction. Wiring must not
be of such length or wire size which would cause
the notification appliance to operate outside of its
published specifications. Improper connections can
prevent the system from alerting occupants in the
event of an emergency.
Wire sizes up to 12 AWG (3.31 mm²) may be connected to the wiring terminals. The terminals are
pre-set to accommodate 12 AWG wiring.

Make wire connections by stripping about 3/8” of
insulation from the end of the wire. Then slide the
bare end of the wire under the appropriate clamping plate and tighten the clamping plate screw.
1. Connect the speaker as shown in Figure 1.
2. Set speaker volume by selecting voltage input
jumpers as shown in Figure 2.
3. Mount according to instructions for the application’s appropriate configuration.
WIRING TERMINALS
1. Speaker Positive (+). Line in and out
2. Speaker Negative (COM). Line in and out.
NOTE: Do not loop electrical wiring under terminal
screws. Wires connecting the device to the control
panel must be broken at the device terminal connection in order to maintain electrical supervision.
SET SPEAKER VOLUME
In order to select the tap settings for given voltage
input (25V or 70.7V) select the jumper selections as
noted. Use the jumper connector to select tap setting for the desired speaker volume.

System Sensor offers a wide range of power settings
for your life safety needs, including ⅛,¼,½,1, 2, 4
and 8W.

Signal levels exceeding 130% rated signal voltage
can damage the speaker. Consequently, an incorrect
tap connection may cause speaker damage. This
means that if a 25V tap is selected when a 70.7V
amplifier is being used, speaker damage may result.
Therefore, be sure to select the proper taps for the
amplifier voltage/input power level combination
being used.

WARNING
THE LIMITATIONS OF SPEAKERS
Always make sure that the individual speakers
are tested after installation per NFPA regulations.
The speakers may not be heard. The loudness of
the speaker meets (or exceeds) current Underwriters
Laboratories’ standards. However, the speaker may
not alert a sound sleeper or one who has recently
used drugs or has been drinking alcoholic bever-
ages. The speaker may not be heard if it is placed
on a different floor from the person in hazard or
if placed too far away to be heard over the ambient noise such as traffic, air conditioners, machinery or music appliances that may prevent alert
persons from hearing the alarm. The speaker may
not be heard by persons who are hearing impaired.
