HOW TO INSTALL CONDUIT PLUGS
In order to maintain watertight performance, any unused conduit openings in
SpectrAlert Advance weatherproof back boxes must be sealed using conduit
plugs provided with the product. First slide the O-ring onto the conduit plug
that is shipped with the unit. Install the conduit plug and O-ring in any un-
used threaded opening on the top and bottom of the back box using Teflon
tape or silicone sealant on the plug’s threads. Tighten the plug so it com-
presses the O-ring slightly without pushing it out of place. Do not overtighten.
Repeat for any unused threaded openings in the back box.
LIQUID-TIGHT CONNECTORS AND HOW TO USE THEM
This section provides and overview of the different types of liquid-tight con-
nections available. It also shows how to use the connectors to provide a water-
tight seal when connecting conduit to the outdoor device weatherproof back
boxes-either through the rear knockout holes or through the threaded open-
ings on the top and bottom of the back box.
TYPES OF LIQUID-TIGHT CONDUIT CONNECTORS
The conduit openings used to bring wire into any SpectrAlert Advance prod-
uct should always be protected with a watertight conduit connector. There are
several connector options available, including:
• Flexible liquid-tight conduit connector available in metal or plastic
• Rigid PVC conduit connector
• Cord grip connector
• Rigid conduit hub
While the proper SpectrAlert Advance weatherproof back box or mounting
plate must be used with the correct product in order for the installation to
remain watertight, each of the connectors above can be used in the threaded
conduit openings or the rear knockouts as appropriate for the installation.
For example, when a System Sensor outdoor notification product is installed
properly in conjunction with the appropriate plastic or metal outdoor back
box, it will provide a NEMA4X rating. However, when a rear knockout is re-
moved from the back box, the product no longer maintains this rating unless
a NEMA4X-rated liquid-tight conduit connector is used.
The use of silicone sealant in the rear knockouts or threaded conduit openings
is NOT recommended in lieu of using a liquid-tight connector or the provided
conduit plugs. This approach will result in an unapproved installation that
may not have the required watertight properties.
In applications where local codes do not require product wiring to be installed
in conduit, it is recommended that a watertight cord grip connector or a wa-
tertight connector with a small length of conduit be used when using the rear
knockouts to maintain a watertight seal.
HOW TO INSTALL LIQUID-TIGHT CONDUIT CONNECTORS IN REAR
KNOCKOUTS
To install a liquid-tight conduit connector, first remove a rear knockout from
the metal weatherproof back box by placing the flat blade of flat blade screw-
driver along the edge of the slot and striking the screwdriver as you slowly
work blade around the slot.
Insert the liquid-tight conduit connector into the knockout opening. Make
sure that the connector’s gasket is in between the connector and the back
box. If a gasket is not provided with the connector, follow the manufacturer’s
instructions on how to use the connector in a knockout (an O-ring may need

FCC STATEMENT
SpectrAlert Strobes and Horn/Strobes have been tested and found to comply with the
limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference when the equip-
ment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation
of this equipment in a residential area is likely to cause harmful interference in which
case the user will be required to correct the interference at his own expense.
to be purchased separately). Attach the conduit connector to the conduit per
the manufacturer’s instructions. Next, tighten the conduit connector nut on
the inside of the back box and then secure the weatherproof back box to the
mounting surface.
Remember to plug any unused conduit openings with the conduit plugs pro-
vided (see How to install conduit plugs).
HOW TO INSTALL LIQUID-TIGHT CONDUIT CONNECTORS IN
THREADED OPENINGS
To install a liquid-tight conduit connector, first secure the weatherproof back
box to the mounting surface. Thread the liquid-tight conduit connector into
a threaded opening following the connector manufacturer’s instructions for
liquid-tight applications (this may require the use of Teflon tape or another
thread sealant). Finally, connect the conduit to the connector per the manu-
facturer’s instructions. See Figures 5 and 6.
