Operation

Maintained contact
For points connected to the keyswitch and programmed for a maintained contact, an open on
the sensor loop turns the area All On (armed). The control panel force arms all faulted points,
regardless of the entry in the FA Bypass Max program item. Returning the circuit to normal
turns the area off.
Momentary contact
For points connected to the keyswitch and programmed for a momentary contact, shorting the
arming sensor loop toggles the area's arming state between All On (armed) and Off
(disarmed). The control panel force arms all faulted points, regardless of the entry in the FA
Bypass Max program item.
Refer to Area Parameters and Point Assignments in RPS Help or the control panel Program Entry
Guide.
Silence the bell
To silence the bell (stop Alarm Bell output) if the system is On (armed), operate the keyswitch
to turn the area off. If the area is disarmed, turn the keyswitch once to start the arming
process. Turning the keyswitch a second time stops the arming process and silences the bell.
9.2.2

Installation and control panel wiring (keyswitches)

For maintained switches, connect the EOL resistor for the point at the keyswitch so that the
switch opens the circuit when it operates. A short on the circuit produces an alarm if the area
is armed and a trouble if it is disarmed.
For momentary keyswitches, connect the EOL resistor at the keyswitch point so that when the
keyswitch operates, it shorts the resistor. An open on the circuit causes an alarm if the area is
on (armed) and a trouble if it is off (disarmed).
