7. DOOR MONITORING (NO ELECTRIC LOCKS)
The panel may also be used to monitor doors where no electric locks are installed. The zone toggle switch serves to arm and disarm the zone and when the zone is armed, the panel will provide a latching alarm signal when the door is opened. Often, on the same panel, some doors are used for lock control and some are used for monitoring only. There is no problem with this.
A door switch which is closed when the door is closed, is mounted at the door and wires to the panel terminals as shown in Figure 17. When the toggle switch is in the on position, the zone is armed and the green indicator will illuminate when the door is closed. When the door opens, the indicator will turn red (violation condition) and the Sonalert will sound. When the door is reclosed, the indicator will turn orange and the violation condition can now be reset. Momentarily depressing the panel reset toggle will silence the alarm and return the indicator to green.
When the toggle switch is in the off position, the zone is disarmed. The bicolor indicator will remain green when the door is closed but will turn off when the door opens rather then going into the violation condition (red). This allows continued monitoring without alarm condition. The toggle switch itself will illuminate yellow when the zone is disarmed.
Only certain of the panel options are usefull if the panel is used for monitoring only. The Silence Latch can avoid long soundings of the alarm (see Sections 2.1 and 5.1).
There is no reason to have a violation alarm delay for zones used for door monitoring only, as there is no electric lock which requires time to resecure. To remove the delay, identify the zones on the circuit board that are for monitoring only and identify the large capacitor on the rear of the board associated with that zone. Snip off and discard the capacitor and the delay will be eliminated.
On a custom basis, the factory can supply the panel with no toggle switches mounted at all so that in a monitoring application, the zones cannot be disarmed. If such a configuration has been delivered, wiring is still as shown in Figure 17.
