Wiring the Tamper Switch
Tamper switches integrated on the OSY-TS model of Series
C200, C300, LFC300, 2000SS, and 3000SS assemblies add
protection against fire.
The supervisory tamper switch consists of two SPDT switches.
The device is designed to send a signal when the valve is closed
and when the switch is removed from the valve. In the neutral
position, the switch indicates the valve is fully open. Closing
the valve causes the switch rod to come out of the valve stem
groove, activating the switch. Removing the device also acti-
vates the switch.
Connect the wires to a fire alarm control panel in accordance
with the schematic diagram and the wiring notes on page 2.
