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 7.) This spring will automatically disengage when
the product is installed, to enable supervision of the final system.

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.
MOUNTING AND REMOVNG APPLIANCE
1. Attach mounting plate to junction box using two of the provided Philips
head screws. (See Figures 8 and 9.)
2. Connect field wiring according to terminal designations. (See Figure 5.)
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, press the
locking button after loosening the captive mounting screw.
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.

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 10.)

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 11 and 12.)
2. The wall mount box must be mounted with the up arrow pointing up. (See
Figure 13.)
