BEFORE INSTALLING

Please read the System Sensor Voice Evacuation

Application Guide, which provides detailed in-

formation 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 require-

ments.

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 se-

lectable tap settings from ⅛to 8 Watts. These prod-

ucts are designed for high efficiency sound output

with low total harmonic distortion to offer high fi-

delity sound output.

Its clear audibility is designed to meet life safety

needs from fire to emergency communication mes-

sages. With its wide frequency range it can also

be used for general signaling such as paging and

background music. The SPCW8 speaker is listed

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 ple-

num 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 Electri-

cal Code) and applicable local codes. System Sensor

recommends installing fire alarm speakers in com-

pliance 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 con-

nected to the wiring terminals. The terminals are

pre-set to accommodate 12 AWG wiring.

AVAILABLE POWER SETTINGS

System Sensor offers a wide range of power settings

for your life safety needs, including ⅛,¼,½,1, 2, 4

and 8W.

Sound levels data per UL 1480 and CAN/ULC-S541

can be found in Table 1. Directional characteristics

CAUTION

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.

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 clamp-

ing 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 applica-

tion’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 con-

nection 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 set-

ting for the desired speaker volume.

¾ inch knockouts are provided for conduit entry

way. Compatible with plenum rated cable and ple-

num whip flex conduit.

To remove the ¾ inch knockout, we recommend

you use a flat head screwdriver, place the blade of

the flat head screwdriver in the inner edge of the

knockout. Strike the screwdriver as you work your

way around as shown in Figure 4:

FLUSH MOUNTING INSTALLATION

1. Connect field wiring to terminals, as shown in

Figure 1.

2. Select the power tap settings using the jumper for

⅛, ¼, ½, 1, 2, 4, 8W.

3. Mount speaker to supplied back can using

mounting screws provided.

CAUTION

Factory finish should not be altered: Do not paint!

CEILING TILE INSTALLATION (WITH BACK CAN)

1. Place ceiling tile with finished surface facing

up over a large garbage can (provides support and

saves clean up time).

2. Cut hole in the center of the ceiling tile using the

SB-SPC8 tile support opening as a template.

3. Flip the ceiling tile over and position the SB-SPC8

tile bridge on the unfinished side of the ceiling tile.

4. Punch out knockout in the supplied back can and

wire per the NEC. The back can is listed to accom-

modate plenum cable or plenum cable whip and

feed cable or whip through the knockout.

5. Install the SB-SPC8 tile bridge to the backcan

using the supplied clips and customer supplied

screws.

6. Connect field wiring to terminals, as shown in

Figure 1.

7. Select the power tap settings using the jumper for

⅛, ¼,½, 1, 2,4,8W.

8. Install the ceiling speaker using (4) 8-32 screws

provided with the ceiling speaker, sandwiching the

SB-SPC8 tile bridge and ceiling tile in between. The

screws anchor into the extruded threaded holes in

the SB-SPC8 tile bridge.

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 ambi-

ent noise such as traffic, air conditioners, machin-

ery or music appliances that may prevent alert

persons from hearing the alarm. The speaker may

not be heard by persons who are hearing impaired.
