RDC-1 Recessed Door Contact
The Recessed Door Contact is a small Door Contact that is installed within door frame and door and concealed for
protection. The Door Contact monitors door opening / closing. When the door opens, the magnet moves away from the Door
Contact, causing the Door Contact to transmit door open signal to the Control Panel. When the door closes and the Door
Contact detects magnet again, it will transmit a door close signal.

LED Indicator
In Normal operation mode, the LED indicator remains off except in the following situations:
When the Door Contact is activated under Low battery condition.
When the Door Contact is activated under Test mode.
When the Door Contact is activated under Test mode.
Supervision
The Door Contact will automatically transmit Supervisory signals to the Control Panel at random intervals of
30 to 50 minutes in Normal Operation Mode.
If the Control Panel has not received the signal from the Door Contact for a preset period time, the Control Panel
will indicate that particular Door Contact is experiencing an out-of-signal problem.
Battery
The Door Contact uses one 3V CR2 Lithium battery as its power source. It is also capable of detecting low battery.
When the battery is low, a low battery signal will be sent to the Control Panel along with regular transmission. The
LED will light up when the Door Contact is activated under low battery status. When battery is exhausted, the Door
Contact will stop all function and the LED will flash every 4 seconds.
