Outdoor Mounting Installations
K Series Devices
K Series products are designed to be NEMA 4X watertight and operate in a
wide temperature range and can be used either indoors or outdoors. Do not
attempt to use a box other than the one supplied with the product or recom-
mended for the product, as doing so may compromise the NEMA 4X rating.
It is strongly recommended that the device be installed at the same time as
the watertight back box to avoid water accumulation and potential damage.
If you have to replace a device, it is strongly recommended that you replace
the outdoor back box as well.
K series products come with a plastic NEMA 4X outdoor rated back box, as
well as removable side flanges for mounting, weatherproof threaded plugs and
o-rings. The -R series devices do not come with our outdoor rated back box.
The -R series products are intended for use with our WTP watertight NEMA
3R surface mount plates or with use of our NEMA 4X SA-WBB or MWBB
series of metal outdoor watertight back boxes.
NOTE: Shorting Spring feature only available on K series Speaker and Speaker
Strobes.
We offer K series for our wall and ceiling mount horns, strobes and horn/
strobes, See Figure 1. As well as for our wall and ceiling mount Speaker and
Speaker Strobes, See Figure 2.
K SERIES MOUNTING
The following instruction procedures to use when installing the K series de-
vices. All wiring and installations must be in compliance with the National
Electric Code (NEC) and all applicable local electrical and building codes.
1. The weatherproof back boxes come equipped with side flanges for
mounting. The plastic versions come with removable side flanges. We
recommend securing the back box directly to the wall or ceiling using
these flanges. If this approach is not possible or is undesirable for aes-
thetic reasons, installers can use the small screw plugs on the back of the
supplied weatherproof back box to mount directly to the wall or ceiling,
or to a weatherproof electrical back box. For the wall mount products,
an up arrow is indicated on the back box for orientation purposes. If
the small screw knockouts are removed, they must be sealed with an
outdoor or marine rated silicone. For horn, strobes and horn/strobes you
can use the center holes for a single gang box and for a double gang box,
you can use the four outer holes, See Figure 3. For speakers and speaker/
strobes they can only be mounted to a 4x4 weatherproof electrical box. It
is recommended that you use a screwdriver to remove the screw knock-
outs as shown in Figure 4.
2. The back box also includes threaded holes on the top and bottom of the
back box for ¾ inch NPT conduit adapters. In addition, conduit knock-
outs in the back of the box are provided for ¾ inch NPT conduit en-
try. When using the rear conduit entry holes, the unused holes on the
top and the bottom of the outdoor back box must be properly sealed.
Threaded Plugs and O-rings are provided with the product for this pur-
pose. It is recommended to put Teflon tape on the threads of the conduit
plugs to ensure a proper seal. Watertight fittings should be used for all
wiring connections, including the conduit knockouts and screw knock-
outs on the back of the box. See Liquid-Tight Connectors and How to Use
Them for additional recommendations.
NOTE: Assuming the screw knockouts or the rear entry conduit knockouts
are properly sealed, no additional sealing to the mounting surface is needed.
3. Water may compromise the back box due to condensation or direct expo-
sure to rain or snow, it is the responsibility of the installer to make sure
that all openings and connections are properly sealed. Even outdoor in-
stallations that are protected from direct exposure to rain are still subject
to condensation or leakage through hidden areas, such as a soffit.
4. To attach the device mounting plate to the weatherproof back box, use
the four supplied non-painted screws.
5. Follow the wiring instructions described in the indoor installation manual.
NOTE: In areas where humidity is a concern, we recommend blocking the
conduit with minimally expanding foam designed for windows and doors.
6. To mount the device to the mounting plate, hook the tabs on the product
housing into the grooves on the mounting plate. Then, swing the product
into position to engage the pins on the device with the terminals on the
mounting plate. Verify that the tabs on the back of the device are fully
engaged with the mounting plate.
7. Finally, secure the device the mounting plate; for horn, strobes and
horn/strobes you only require the single screw on the front of the hous-
ing. To secure the speaker and speaker strobe you must use all #8-32 x
3 /
8
inch flat head screws supplied.
NOTE: We recommend you use a hand-held screwdriver for the installation of
the mounting plate. If you must use an electric screwdriver use it at its lowest
torque setting.
