Mini Door Contact (MDC-3-ADC2) User Manual V:EN 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 the device. When the door or window opens, the magnet 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 back cover. The front cover(back) contains 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.

When Door Contacts 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. Supervision The Door Contact will automatically transmit Supervisory signals periodically to the Control Panel at random 1 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 tamper switch is designed to protect against unauthorized cover opening. When the tamper is triggered, Door Contact will emit a signal to the Control Panel for reporting, the LED will also light up. Battery The MDC-3-ADC2 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 front and back covers to insert/remove the battery Step 1. Use a flat-headed screwdriver to fit into the slit between the covers as FIG. 1. Step 2. Push the flat-headed screwdriver upwards as FIG. 2 to separate the covers. Step 3. Turn to the other side and repeat Steps 1 and 2. FIG. 1 FIG. 2 Step 4. Once the covers are separated, you can proceed to change the battery. Step 5. After the used battery is removed, press the Learn/Test button 5-6 times to fully discharge before inserting a new battery.
<NOTE>
Make sure the battery mark with the positive side (+) faces upwards when inserting the new battery. Make sure to insert or place the battery from the bottom as indicated in FIG. 3. Step 6. To re-place the covers:
- Make sure the Tamper Compression Mark is aimed at the Tamper Switch (FIG. 4).
- Align the rounded corners of the back cover with the rounded corners with the front cover and FIG. 3 push the covers towards each other until you hear a click sound (FIGs. 5 and 6). FIG. 4 FIG. 5 FIG. 6 Test Mode The Door Contact can be put into Test mode for 3 minutes by pressing the Test Button once. Under Test Mode, the LED will light up whenever the Door Contact is activated. Each additional Test Button press will reset Test Mode time to 3 minutes. Getting Started Step 1: Remove the battery insulator 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 Door Contact to send signals to the Control Panel. Step 4: If the Control Panel successfully receives the signals, 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 learnt-in, put the Control Panel into Walk Test mode, hold the Door Contact at the 2 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. Installation Mounting Methods Mount the Door Contact on the fixed frame of a door/window using the Velcro tape, adhesive tape, or Screw. Mount the magnet on the mobile object (door/window) using Screw Mounting or Adhesive Mounting. Align the rib marks on the magnet and the Door Contact. Where required, use the magnet spacer to better align the rib marks.
< NOTE >
The magnet should be no more than 15mm from the Door Contact when the door is closed. Mounting Methods for Door Contact Screw Mounting The back cover has two Mounting Holes (knockouts), where the plastic is thinner, for mounting purpose. To mount the Door Contact:
I. Remove the back cover from the Door Contact. II. Break through the two knockouts on the back cover. III. Use the holes as a template and drill the holes into the door/window frame. IV. Insert wall plugs if the Door Contact is to be mounted on plaster or brick. V. Screw the back cover onto the wall plugs with a Phillips screwdriver. VI. Attach the front cover to the back cover. 3 Velcro tape Mounting:
I. The Door Contact can be mounted using the Velcro tape provided. Clean the surface to be mounted and the back of the Door Contact with degreaser. Do not mount the Door Contact on a rough surface or a surface with cracking paint. II. The Velcro tape can be separated into the Hook and the Loop (FIG. 7). III. Remove the liner of the Hook and attach the Hook to the back of the Door Contact. Press the Hook firmly for 30 seconds to ensure good contact (FIG. 8). IV. Remove the liner of the Loop and apply the Loop to the desired mounting location as in FIG. 9. Press the Loop firmly for 30 seconds to ensure good contact. Apply the Door Contact to the Loop taped on the door/window frame (FIGs. 10 & 11.) V. Hook Loop FIG. 7 FIG. 8 FIG. 9 FIG. 10 FIG. 11 Double-sided Adhesive Mounting:
