Keyswitch Operation
Shorting and restoring the point sensor loop toggles the
system On and Off. All faulted points are bypassed. See
POINT CODES in the D2212 Program Entry Guide.
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.
Easikey
You can use a Radionics Easikey access system to turn the
system Off. Program the
Keyswitch prompt to Easikey (see
the
D2212 Program Entry Guide for instructions). You must
use a 12VDC option for the Easikey installation. See the
Easikey Installation and Operation Instructions. Easikey is
not for use in UL installations.
Connect the Easikey door controller to the panel using a
D133/D134 Relay Module as shown in Figure 13. Make
certain to connect the common for the Easikey's 12VDC
power supply to terminal 10 on the panel.
Points
Point Parameters
On-Board Point 1
Point 1 is a powered sensor loop. Review the Radionics
Technogram: Smoke Detectors Compatible with the D2212
(73-07358-000) for a list of compatible detectors.
Point 1 is supervised with a 2.0K EOL resistor. The voltage
range for two-wire smoke detectors is 10.2 to 13.9 VDC.
Points 2 to 6
Points 2 to 6 are supervised with 1.0K EOL resistors.
Open Loop = Greater than 8.9 VDC, but less than
13.9 VDC.
Normal Loop = Greater than 2.5 VDC, but less than
8.5 VDC.
Shorted Loop = Greater than 0.0 VDC, but less than
2.0 VDC.
Points 7 and 8
Points 7 and 8 are
not supervised with EOL resistors.
Open Loop = Greater than 2.4 VDC, but less than
13.9 VDC.
Normal (Closed) Loop = Greater than 0.0 VDC, but
less than 1.4 VDC.
Point Response Time
The panel scans point sensor loops every 500 milliseconds.
A point must be faulted for 2 scans (one second) before the
panel initiates an alarm.
Keyswitch
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 (except points 7 and 8).
You can use the external relay outputs and D133/D134
Relay Modules to activate arming status lights for keyswitch
arming stations. See the
Relays section in the D2212
Program Entry Guide.
Programming
See
POINT CODES in the D2212 Program Entry Guide for
the correct programming for points used for keyswitches.
Installation
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 12.
