Mini Door Contact (MDC-3)
Introduction
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.

Press the Test button to transmit a learn code.
Press the Test button once to enter Test Mode for 3 minutes.
Red LED Indicator
Tamper Switch
Battery
Mounting Holes (Knockouts)
Tamper Compression Mark

Magnet Spacer
Accessories Included
1 Magnet
1 Double-sided adhesive Magnet Spacer
2 Screws
4 Wall Plugs
1 Double-sided adhesive Velcro tape (for Door Contact)
1 Double-sided adhesive tape pad (for Magnet)
2 Magnet mounting screws
In Normal operation mode, the LED indicator remains off except in the following situations when:
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.
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 that particular Door Contact is experiencing an out-of-signal problem.
It 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.
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:
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 upon 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.
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 Door Contact to send signal to the Control Panel.
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 learnt-in, put the Control Panel 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.
To open the cover of the Door Contact:
Step 1. Use a flat-headed screwdriver to fit into the cover opening hole on one side as (Pic1).
Step 2. Push the flat-headed screwdriver upwards as (Pic2).
Step 3. Turn to the other side and repeat Step 1 and Step 2.
(Pic 1) (Pic 2)
Step 4. Once opened the cover, you can proceed to change the battery etc.
Step 5. To replace the cover:
Make sure the Tamper Compression Mark is aimed at the Tamper Switch (Pic 3).
Also make sure the bottom hooks of the back cover is latched on the bottom of the front cover (back) as (Pic 4)
Fit the bottom hooks into the bottom latches of the front cover (back) then push it downwards as (1) in (Pic 5), then push forward (2) the entire back cover to close it until you hear a clip sound.
(Pic 3) (Pic 4) (Pic 5)
Mount the Door Contact using one of the below mounting methods: Velcro tape Mounting or Screw Mounting.
Mount the magnet on the more mobile object (such as door) using either the double-sided adhesive pad or the screws provided.
Align the magnet according the rib mark on Door Contact. Where required, use the Magnet Spacer to better align the magnet to the rib marks.
< Note >
The magnet should be no more than 15mm from the detector when the door is closed.
Screw Mounting
The back cover has two Mounting Holes (knockouts), where the plastic is thinner, for mounting purpose.
To mount the Door Contact:
Remove the cover (See Installation above).
Break through the knockout on the back cover.
Using the holes as a template, drill both holes.
Insert wall plugs if fixing into plaster or brick.
Screw the back cover into the wall plug using a Philips screwdriver.
Attach the front cover to the back cover (see Pic 3 ~ 5 above).
Velcro tape Mounting:
The Door Contact can be wall mounted using Velcro tape provided.
Hooks, Loops
Clean the wall mounting location and back of the Door Contact with degreaser. Do not mount on wall with cracking paint or rough surface.
The Velcro tape can be separated to Hook and Loop side.
Remove the protective cover of the Hook side and attach to the back of the Door Contact. Press firmly for 30 seconds to ensure good contact. (Pic 6.)
Remove the protective cover of the Loop side and apply to desired mounting location as in (Pic 7.) Press firmly for 30 seconds to ensure good contact.
(Pic 6.) (Pic 7.)
Apply the Door Contact on the Loop side Velcro taped on the wall (Pic 8 & 9.)
(Pic 8.) (Pic 9.)
Door / Window, Frame, Rib-Marks
Screw Mounting
The back cover of the magnet has two Mounting Holes for mounting purpose.
To mount the Magnet:
Open the back cover by using a flat-headed screwdriver to fit into the caved in area and push upwards.
Using the holes as a template, drill both holes.
Screw the back cover into the door/window using a Philips screwdriver. Where required, use the Magnet Spacer to better align the magnet to the rib marks.
Attach the front cover to the back cover. If the front cover is stabilized onto the back cover, you should hear a Click sound.
Screw Mount with Spacer, Screw Mount without Spacer
The Magnet can also be mounted using the double-sided adhesive tape pad or the double-sided adhesive Magnet Spacer.
Clean the mounting location and back of the Magnet with a suitable degreaser.
Remove the protective covering from one side of the double-sided adhesive pad or the double-sided adhesive Magnet Spacer. Apply to the back of the Magnet and press firmly for 30 seconds to ensure good contact.
Remove the other cover and firmly press the Magnet onto the desired location for 30 seconds..
