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 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
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

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.

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.
