ShorTing Spring
NOTE: A shorting spring is provided between terminals 2 and 3 of the mount-
ing plate to enable wiring checks after the system has been wired, but prior
to installation of the final product. This spring will automatically disengage
when the product is installed, to enable supervision of the final system.

NOTE: V suffix refers to high volume device,

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 indoor WaLL or CeiLing produCTS
1. Attach mounting plate to junction box as shown in Figures 4 and 5. The
mounting plate is compatible with 4˝ x 4˝ x 2 1 /
8
˝ junction boxes. If using
a back box skirt or trim ring, attach the mounting plate to the skirt or
trim ring and then attach the entire assembly to the junction box (see
Figures 4, 5, 6 and 7).
2. Connect field wiring to terminals, as shown in Figure 1.
3. If the product is not to be installed at this point, use the paint cover to
prevent contamination of the mounting plate.
4. To attach product to mounting plate, remove the paint cover, then hook
tabs on the product housing into the grooves on the mounting plate.
5. Then, swing 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. For tamper resistance, the standard captivated
mounting screw may be replaced with the enclosed Torx screw.
k SerieS mounTing
1. K Series products may be used indoors or outdoors. They must be in-
stalled using the proper SpectrAlert Advance weatherproof back box. Do
not attempt to use boxes other than those specified for use with the
product.
2. The plastic weatherproof back box is equipped with removable side
flanges for mounting. The back box may be secured directly to the wall
or ceiling using the flanges(plastic or metal back boxes) or by using the
knockout plugs(plastic back boxes). Knockout plugs are provided to
mount directly to the wall or ceiling or to a 1900 weatherproof electrical
box, see Figure 12.
3. Threaded holes are provided in the sides of the box for ¾ inch conduit
adapters. Knockout plugs in the back of the box can be used for ½ or
¾ inch rear entry. Unused holes must be sealed. Plugs and O-Rings are
provided with the box for this purpose.
4. It is the responsibility of the installer to make sure that all openings and
connections are sealed properly. Outdoor installations that are protected
from direct exposure to rain are still subject to condensation or leakage
through hidden areas, such as a soffit.
5. Water may pool on the back box due to condensation or direct exposure
to rain or snow. Use watertight fittings for all wiring connections, includ-
ing the knockout plugs on the back of the box. When using the plastic
plugs to fill unused threaded holes, make sure the O-rings supplied are
properly positioned on the plug. The plugs must be sealed with PTFE
thread seal tape.
