ITI WIS Installation Instructions

60-353-235
About This Document
This document describes how to install, program, and
test the Wireless Interior Siren (WIS) for use in com-
patible ITI security systems.
Product Summary
The WIS uses the existing premises electrical wiring
for receiving control panel (panel) signals. Since there
is no direct connection to the panel, any number of
sirens can be installed in a system.
The WIS receives signals from the panel, only when
the panel is powered by an optional Line Carrier
Power Transformer (60-346-500). The panel sends sig-
nals through the transformer and over the electrical
Wiring.
The WIS responds to panel signals by activating its
built-in piezo sirens and the red LED located above
the top piezo.
In case of a power failure, a backup battery (not
included) provides power for the WIS. When the bat-
tery is low, the WIS beeps once every 60 seconds, indi-
cating the battery needs replacing.
The WIS also includes screw terminals for connecting
a low-current, external siren.

Installation Guidelines

Use the following guidelines when installing a WIS:
ν
®
CareTaker Plus and Custom Version panels, and
®
Commander 2000 and Custom Version panels
must be powered using the optional Line Carrier
Power Transformer (60-346-500).
ν
®
UltraGard and Custom Version panels must be
powered using the optional Line Carrier Power
Transformer (60-678)
ν
SX-V panels must have software dated 11/30/87
or later installed for WIS operation.
ν
The WIS must have a 9-volt battery installed for
correct operation. The battery can be alkaline, lith-
ium, or NiCd type.
Note:
In UL listed installations, NiCd batteries cannot
be used in the WIS.
ν
Try to avoid installing the WIS on circuits that
include TVs, computers, or appliances such as
refrigerators or microwave ovens. These products
can generate noise on the AC lines that may block
panel signals to the WIS.
ν
The panel transformer and the WIS must be
plugged into outlets on the same electrical phase
to ensure consistent operation.
ν
When connecting an exterior siren to the WIS, use
the Hardwire Exterior Siren (13-046) only.

Setting the WIS DIP Switches

This section describes the WIS DIP switches and how
to set them for the desired WIS operation. Locate the
WIS DIP switches by turning the WIS upside-down
and removing the battery cover on the back (see Fig-
ure 1).
Note:
In UL listed systems, all switches must be off.
