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's 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.

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).
