Optical Door Contact (OPDC-1) User Manual
The Optical Door Contact, integrating infrared sensor, monitors the opening/closing of specified devices (e.g. door or window).
By using infrared detection technology, the OPDC can detect if the door or window is open or closed, without the need of an
additional magnet. The OPDC will transmit alarm signals when it detects a change, and keep your home protected.
The Optical Door Contact consists of a cover and base. The base contains all electronics and provides a means for fixing the
device. An enclosed PCB tamper switch provides tamper protection against unauthorized device opening.

LED Indicator
In Normal operation mode, the LED indicator remains off except in the following situations:
When the Optical Door Contact’s tamper switch is triggered.
Every time the Optical Door Contact is activated under Tamper or Low battery condition.
Every time the Door Contact is activated and transmitting the signal under the Test mode.
Supervision
The Optical Door Contact will automatically transmit Supervisory signals periodically 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 Optical Door Contact for a preset period time, the
Control Panel will indicate that particular Door Contact is experiencing an out-of-signal problem.
Tamper Switch
It is designed to protect against unauthorized cover opening. When the tamper is triggered, the Optical Door
Contact will emit a signal to the Control Panel for reporting, the LED will also light up.
Battery
The Optical Door Contact uses one
1.5V AAA Alkaline battery
as its power source, and 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 Optical Door Contact will stop all function and the LED will flash every 4 seconds.
