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 3.

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.
MOUNTING
1. Attach mounting plate to junction box. The mounting plate is compatible
with 4" x 4" x 2 / " or deeper junction boxes. (See Figure 7.)

2. Connect field wiring to terminals, as shown in Figure 4.
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, remove the protective dust cover, hook
tabs on the top of the product housing into the grooves on mounting plate.
5. 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.
6. Secure product by tightening the single mounting screw in the front of the
product housing.
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.
Factory finish should not be altered: Do not paint!
Do not over tighten mounting plate screws; this may cause mounting plate
to flex.

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 of the screw until it dis-
engages from the housing. Replace
with the supplied Torx screw. (See
Figure 8.)
SURFACE MOUNT BACK BOX MOUNTING
1. The surface mount back box may be secured directly to the wall. A ground-
ing bracket with ground screw capability is provided if needed. For wall see
Figure 9.
FIGURE 9. WALL SURFACE MOUNT BACK BOX
2. The wall mount box must be mounted with the up arrow pointing up. (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. NOTE: Use caution not to strike the knockout near the top edge
of the surface mount back box.
