Wireless Interior Siren
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 signals 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 battery is low, the WIS beeps once every 60 seconds, indicating the battery needs replacing.
The WIS also includes screw terminals for connecting a low-current, external siren.
