CONNECTION DIAGRAM
Tamper Switch
There is provision to add 2 resistors to the printed circuit board to allow remote alarm
equipment to monitor the tamper microswitch and the interconnecting wires.
The resistor positions are marked on the printed circuit board as 'S' and 'P'. The value
of the resistors is specified by the alarm equipment manufacturer.
The 'S' is a resistor in series with the microswitch.
The 'P' is a resistor in parallel with the microswitch.
If line monitoring is not required a jumper must be soldered in place of the 'S' resistor
