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 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. Our line of speakers is designed

to be used at either 25 or 70.7 volts, and operate at any one of four input

power levels. Our speakers are suitable for dry and damp environments.

These products are electrically backwards compatible with previous genera-

tion of System Sensor speakers. With its low total harmonic distortion, the

System Sensor SPL series offers high fidelity sound output. Wall and ceiling

products may be used interchangeably (wall products may be used on ceiling

and ceiling product may be used on wall).

The speakers, and all power level settings, are listed to ANSI/UL 1480 require-

ments for public mode applications.

FIRE ALARM SYSTEM CONSIDERATIONS

All wiring must be installed in compliance with the National Electrical Code

(NEC) and applicable local codes. System Sensor recommends installing fire

alarm speakers in compliance with NFPA 72, ANSI/UL 1480 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 appli-

ance 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 (2.5 mm²) may be used with the mounting plate. The

mounting plate ships with the terminals set for 12 AWG wiring.

Make wire connections by stripping about

" 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.

See Figure 1 for wiring terminals and strip guide reference.

1. Connect the speaker as shown in Figure 1.

2. There are two rotary switches on the back of the product. The first switch

is used to select either 25 or 70.7 volts input and the second switch is used to

select the input power of ¼, ½, 1 or 2 watts. (See Figure 2.)

MOUNTING

1. Attach mounting plate to junction box. The mounting plate is compatible

with 4" x 4" x 2

" or deeper junction boxes. (See Figures 4 and 5.)

1. Connect field wiring to terminals, as shown in Figure 1.

2. If the product is not to be installed at this point, use the protective dust

cover to prevent contamination of the wiring terminals on the mounting plate.

3. To attach product to mounting plate, remove the protective dust cover, hook

tabs on the top of the product housing into the grooves on mounting plate.

4. Then, hinge the product into position to engage the pins on the product

with the terminals on the mounting plate. Make sure that the tabs on the back

of the product housing fully engage with the mounting plate.

5. Secure product by tightening the single mounting screw in the front of the

product housing.

CAUTION

The “hold in place” snaps are not intended to secure the product to the back

box. The product must be secured to the back box using the screws provided.

CAUTION

Factory finish should not be altered: Do not paint!

CAUTION

Do not over tighten mounting plate screws; this may cause mounting plate

to flex.

SHORTING SPRING FEATURE

System Sensor notification appliances come with a shorting spring that is pro-

vided between terminals 2 and 3 of the mounting plate to enable system con-

tinuity checks after the system has been wired, but prior to installation of the

final product. (See Figure 3.) This spring will automatically disengage when

the product is installed, to enable supervision of the final system.

AVAILABLE POWER SETTINGS

System Sensor offers a wide range of power settings for your life safety needs,

including ¼, ½, 1, and 2W.

Sound levels data per UL 1480 can be found in Table 1. Directional character-

istics can be found in Table 2.

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.

TAMPER SCREW

For tamper resistance, the standard captive screw may be replaced with the

enclosed Torx screw.

1. To remove the captive screw, back out the screw and apply pressure to the

back until it disengages from the housing. Replace with the supplied Torx

screw. (See Figure 6.)

SURFACE MOUNT BACK BOX MOUNTING

1. The surface mount back box may be secured directly to the wall or ceiling.

A grounding bracket with ground screw capability is provided if needed. For

wall see Figure 7, and for ceiling see Figure 8.

NOTE: Ceiling Surface Mount Back Box, SBBCRL/CWL is a common back box

for ceiling horn strobes, strobes and ceiling speakers and speaker strobes. Use

the top mounting holes for ceiling speaker and speaker strobe products. (See

Figure 10.)

3. Threaded knockout holes are provided for the sides of the box for ¾ inch

conduit adapter. Knockout holes in the back of the box can be used for ¾

inch rear entry.

4. To remove the ¾ inch knockout, we recommend you use a flat head screw-

driver, 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 11.

5. V500 and V700 raceway knockouts are also provided. Use V500 for low

profile applications and V700 for high profile applications.

6. To remove the knockout turn pliers up, as shown in Figure 12.
