Keyswitch

Description

You can connect a maintained or momentary
contact arming station (keyswitch) to master arm/
disarm any of the areas in the system. The
keyswitch is connected to an on-board or off-
board point's sensor loop. Relays can be
programmed to activate arming status LEDs for
keyswitch arming stations. See the Relays
section of the D9000/D7000 Series Program
Entry Guide (74-07695-000).

Programming

See the Point Assignments section of the D9000/
D7000 Series Program Entry Guide (74-07695-
000) for the correct programming for points used
for keyswitches.

Installation

For maintained switches, connect the end-of-line
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. See Figure
18.
For momentary switches, connect the end-of-line
resistor for the point at the keyswitch so that the
switch shorts the resistor when it operates. An
open on the circuit produces an alarm if the area
is armed and a trouble if it is disarmed. See
Figure 18.

Keyswitch Operation

Maintained Contact
If you program the point the keyswitch is
connected to for a maintained contact, an open
on the arming circuit arms the area. All faulted
points are force armed, regardless of the entry in
the FA Bypass Max program item. Returning the
circuit to normal disarms the area. See Area Wide
Parameters and Point Assignments in the D9000/
D7000 Series Program Entry Guide (74-07695-
000).
Momentary Contact
If you program the point the keyswitch is
connected to for a momentary contact, shorting
the arming circuit toggles the area's arming state
between armed and disarmed. All faulted points
are force armed, regardless of the entry in the FA
Bypass Max program item. See Point
Assignments in the D9000/D7000 Series
Program Entry Guide (74-07695-000).
Silencing the Bell
To silence the bell (stop Alarm Bell output ) if the
system is armed, operate the keyswitch to disarm
the area. If the area is disarmed, operate the
keyswitch once to start the arming process and a
second time to stop the arming process and
silence the bell.
