Features
LED Indicator
In Normal operation mode, the LED indicator remains off except in the following situations:
When Door Contact’s Tamper switch is triggered.
When the Door Contact is activated with either Tamper or Low battery condition.
When the Door Contact is activated and transmitting the signal under the Test mode.
If the LED flashes to indicate signal transmission, it will flash twice rapidly upon receiving acknowledgement
from the Control Panel.
Supervision
The Door Contact will automatically transmit Supervisory signals periodically to the Control Panel at
random intervals of 15 to 18 minutes in Normal Operation Mode.
If the Control Panel has not received the signal from the Door Contact for a preset period of time, the
Control Panel will indicate that particular Door Contact is experiencing an out-of-signal problem.
Tamper Switch
The Door Contact is protected against any attempt to open the device cover or to detach the device
from its mounting surface.
If the Door Contact detects a tamper condition of cover opening or device removal, a tamper signal will
be sent to the Control Panel to remind the user of the condition.
Battery
The MDC-5 uses one
3V CR2450 Lithium battery
as its power source. The Door Contact 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.
