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
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.
See Figure 1 for wiring terminals and strip guide reference.
1. Connect the speaker. (See 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 AND REMOVING APPLIANCE
1. Attach mounting plate to junction box. (See Figures 4 and 5.)
2. Connect field wiring to terminals. (See Figure 1.)
3. 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.
4. To attach product to mounting plate:
a. Remove the protective dust cover.
b. Hook the tabs on the top of the product housing into the grooves on mount-
ing plate.
c. Pivot the product into position to engage the terminals on the mounting
plate. Make sure that the tabs on the back of the product housing fully en-
gage with the mounting plate.
d. Hold product in place with one hand, and secure product by tightening the
single mounting screw in the front of the product housing.
Ceiling Models only: To remove product from the mounting plate, loosen the
captive mounting screw and press the locking button.
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 a Torx
screw (sold separately).
1. To remove the captive screw, back out the screw and apply pressure to the
back of the screw until it disengages from the housing. Replace with Torx
screw. (See Figure 6.)

NOTE: Wall speaker shown in this example.
INSTALLING A SURFACE MOUNT BACK BOX
1. The surface mount back box may be secured directly to the wall or ceiling.
Use of grounding bracket with ground screw is optional. (See Figures 7 and 8.)
2. The wall mount box must be mounted with the up arrow pointing up. (See
Figure 9.)
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 conduit
adapter. Knockout holes in the back of the box can be used for rear entry.
Wall-mount option supports ½ inch conduit; ceiling-mount option supports
½ inch or ¾ inch conduit.
4. To remove the ¾ inch knockout, place the blade of a flat-head screwdriver
along the outer edge and work your way around the knockout as you strike
the screwdriver. (See Figure 11.)
NOTE: Use caution not to strike the knockout near the top edge of the
surface mount back box.
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. (See Figure 12.)
