This symbol indicates prohibition. The specific prohibited action is provided in and/or around the figure.
This symbol requires an action or gives an instruction.
The 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 Central Panel. The device also has the capabilities of communicating signal
problems along with low battery situations.
The Door Contact design consists of a cover and base. The cover contains all electronics and the base provides a means for fixing the device. An
enclosed PCB tamper switch provides tamper protection against unauthorized device opening and/or removal.

LED INDICATOR
In Normal Operation Mode, the LED will not light when the Door Contact is activated.
When the Door Contact battery voltage is low, every time the Door Contact is activated (device opened/ closed), the LED will light on for 2 sec.
When the cover is opened or the tamper switch is triggered, the LED will light on for 2 seconds. When a tamper condition persists, the LED will
light on for 2 seconds whenever the Door Contact Is activated.
When the Door Contact is in Test mode, the LED will light up every time it is activated.
When the battery is exhausted, the Door Contact will stop all function, the LED will flash every 4 seconds.
4 BATTERY
The Door Contact uses one CR2, 3V Lithium battery as its power source. Please note: ALWAYS replace battery with the correct size and
voltage.
The Door Contact can detect low battery condition. When the battery voltage is low, a low battery signal will be sent to the Control Panel to notify
the condition. The LED will light up when the Door Contact is activated under low battery status. When the battery is exhausted, the Door Contact
will stop all function, the LED will flash every 4 seconds.
When changing batteries, after removing the old batteries, press the Tamper Switch twice to fully discharge before inserting new batteries.
5 SUPERVISORY SIGNAL
If enabled, the Door Contact will automatically transmit Supervisory Signals periodically to the Control Panel at random intervals of 30-50 minutes.
If the Control Panel has not received the signal from the Door Contact for a preset period time, the Control Panel will indicate the particular Door
Contact is experiencing an out-of-signal problem.
6 TEST MODE
Under Normal Mode, press the Test Button to transmit a test signal and learning code to the Control Panel. The Door Contact will also enter the
Test Mode for 3 minutes.
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.
7 GETTING STARTED
Pull out the battery insulator to activate battery.
Put the Control Panel into Learning Mode (please refer to panel operation manual).
Press the Door Contact test button.
Refer to your Control Panel operation manual to complete the learn-in process.
After the Door Contact is learned-in, place the Control Panel into (Walk Test) mode, hold the Door Contact in the desired location, and press the
Test button to transmit test signal to Control Panel. If the Control Panel is within Door Contact signal range, the panel will display door contact
information accordingly.
Proceed with mounting and installation once you are satisfied that the Door Contact location functions properly.
8 MOUNTING METHODS AND INSTALLATION
It is recommended that the Door Contact should be placed on the door frame and the magnet on the door.
Step1. Find a suitable location close to your door/window to install the Door Contact. Conduct a Walk Test to check whether the position is in
Step2. The Door Contact has 2 rib-marks on one side (refer to figure), marking the internal magnet switch location. The door contact should

signal range of the Control Panel.
be installed either upright or inverted, to ensure that the rib-marked side face the magnet.
1. Remove the white caps covering the two mounting holes.
2. Using the 2 mounting holes as a template for appropriate hole positioning.
3. Use the provided wall plugs for plaster/brick installation.
4. Screw the Door Contact into the provided wall plugs using a Philips screwdriver.
5. Replace the white caps to cover the two mounting holes.
marked side of the door contact as shown in figure.
The magnet should not be more than 15 mm from the detector when the door is closed.
Ensure the tamper switch spring is positioned so that it makes contact with the mounting surface through the tamper switch aperture.
Windows can be protected similar to door installations. When fitting to a window fix the magnet to the moving window part and the door
switch to the stationary frame.
9 USING THE EXTENSION TERMINAL.
The Door Contact has an extension terminal to provide enhanced flexibility. The extension terminal forms a closed loop with the device connected to it.
When the device is triggered, the loop will be opened; the Door Contact will also be triggered.
The extension terminal and the internal magnetic switch can function together to trigger the Door Contact when either of them is activated, you can also
choose to disable the internal magnetic switch through JP3 Jumper setting.
To connect the device to extension terminal
Step1. Open the Door Contact by loosening the fixing screw using a Philips screwdriver.
Step2. The upper end of the front case has a thinner plastic knockout. Break through the knockout to create a hole for the wiring connection to
Step3. Connect the device to the extension terminal
the extension terminal.

The Extension terminal may be useful for the following situation.
If the Door Contact cannot be mounted on the door frame, you can connect an additional extension switch to the extension terminal to mount the
Door Contact remotely.
Any dry contact device with N.C. (Normal Close) loop can be connected to the Extension Terminal making the Door Contact serve as an Universal
Transmitter.
Multiple dry contact device can be wired together with Door Contact, as show in diagram below.
NNOOTTEE>>>>
If both the Internal Magnet Switch and Extension Terminal operate together, then
When the protected door is opened/closed or the external device is triggered, the Door Contact activates and transmits a signal
immediately .
However, the Door contact will only transmit a Door Closed or Restored signal after both the door and the external device are restored for
3 sec.
