Keyswitch
7.1.1
Description
You can connect a momentary contact arming station (keyswitch) to turn the D2212 on and off. Connect the keyswitch to
any point sensor loop.
You can use the external relay outputs and D133 (or D134) Relay Modules to activate arming status lights or keyswitch
arming stations. See the Relays section in the D2000 Series Program Entry Guide (P/N: 35114).
7.1.2
Programming
See the POINT CODES Group in the D2000 Series Program Entry Guide (P/N: 35114) for the correct programming for points
used for keyswitches.
7.1.3
Installation
Connect the EOL 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 13).

7.1.4
Keyswitch Operation
Shorting and restoring the point sensor loop toggles the system
On
and
Off
. All faulted points are bypassed. See the POINT
CODES Group in the D2000 Series Program Entry Guide (P/N: 35114).
7.1.5
Silencing the Bell
To silence the bell (stop Alarm Output) if the system is
On
(or part
On
), operate the keyswitch to turn the system
Off
. If the
area is
Off
, operating the keyswitch only silences the bell. It does not turn the system
On
.
