Mini Door Contact (MDC-3) User Manual

The Mini Door Contact monitors the opening/closing of specified devices (e.g. door or window). The Door Contact is fixed to the monitored
device frame with an actuating magnet fixed to th e device. When the door or window opens, the ma gnet moves away from the Door Contact,
activating an internal magnetic switch causing the Door Contact to transmit alarm signal to the Control Panel. The device also has the
capabilities of communicating signal problems along with low battery situations.

The Door Contact design is consisted of a front cover and a bac k cover. The front cover(back) c ontains all electronics and the back cover
provides a means for fixing the device. An enclosed PCB tamper switch provides tamper protection against unauthorized device opening.

Identifying the parts

1. Magnet

- Mount the magnet on the side of the Door Contact where it has 2 rib-marks to indicate the position of the internal magnet switch.
The Door Contact should be installed either upright or inverted to ensure that the rib-marked side faces the magnet.

Features

 LED Indicator

In Normal operation mode, the LED indicator remains off except in the following situations when:

 When Door Contact’s T amper 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.

 Supervision

 The 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 Door Contact for a preset period time, the Control Panel will indicate

1

that particular Door Contact is experiencing an out-of-signal problem.

 Tamper Switch

 It is designed to protect against unauthorized, cover opening. When the tam per is triggered, Door Contact will emit a signal to

the Control Panel for reporting, the LED will also light up.

 Battery

The MDC-3 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.

Changing Battery



You need to open the cover to insert/remove the battery

(Please refer to Installation on how to remove the Door Contact’s cover for details)

After the battery has been removed, press the Learn / Test button 5-6 times to fully discharge before inserting the new battery.

<NOTE>

 Make sure the battery mark with the positive side (+) is faced upwards when inserting the battery.
 Make sure to insert or place the battery from the top right angle in the Front Cover (Back) view:

 Test Mode

The Door Contact can be put into Test mode for 3 minutes by pressing the Test Button on the front cover (back) once. During Test mode,
the LED indicator will turn on upo n triggering. Each press on the Test Button, the Door Contact will transmit a test signal to the Control
Panel for radio range test and resets the test mode back to the 3-minute duration. It will exit Test Mode automatically after the 3 minutes
and returns to Normal Operation mode.

 Getting Started

Step 1: Remove the battery insulator located at the rear side of the Door Contact.
Step 2: Put the Control Panel into learning mode, refer to Control Panel manual for detail.
Step 3: Press the Learn/Test Button on
Step 4: If the Control Panel successfully receives the signal, the Control Panel should respond (e.g. emitting beeps). Refer to your

Control Panel manual to complete the learning process.

Step 5: After the Door Contact is l earnt-in, put the Control P anel into “Walk Test” mode, hold the Door Contact at the desired location,

and press the Test button to confirm if this location is within signal range of the Control Panel.

Step 6: When you are satisfied with the Door Contact at the chosen location, proceed to installation.

Door Contact to send signal to the Control Panel.
