Door Contact (DC-23 / DC-23-R3) User Manual
The Door Contact monitors the opening/closing of specified devices (e.g., doors or windows). 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 signals to the Control Panel. The device also has the capabilities of communicating signal problems along with low battery situations.
The Door Contact’s design consists of a cover and a base. The cover contains all electronics and the base provides a means for fixing the door contact. An enclosed PCB tamper switch provides tamper protection against unauthorized device opening and/or removal.
DC-23 Series Door Contact includes the following models:
DC-23: Door Contact’s cover is secured by a bottom fixing screw.
DC-23-R3: Door Contact’s cover is secured by two latches at top and the bottom.

Features
LED Indicator
In Normal Operation Mode, the LED will not light up when the Door Contact is activated.
When the Door Contact’s battery voltage is low, every time the Door Contact is activated (device opened/ closed), the LED will light up for 2 sec.
When the cover is opened or the tamper switch is triggered, the LED will light up for 2 seconds. When the tamper condition continues, the LED will light up 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 functions, and the LED will flash every 4 seconds.
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 with the loop 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:
For DC-23 model:
Open the Door Contact’s cover with a screwdriver to loosen the cover fixing screw at the bottom of the Door Contact’s cover (see the top-view picture on the right).
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 the extension terminal.
Connect the device to the extension terminal
For DC-23-R3 model:
Use your thumb to press on the Latch, while pressing it, pull out the cover from the base of the Door Contact (see the top-view picture on the right).
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 the extension terminal.
Connect the device to 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 magnet switch to the extension terminal to mount the Door Contact remotely.
Any dry contact devices with an N.C. (Normal Close) loop can be connected to the extension terminal making the Door Contact serve as a Universal Transmitter.
Multiple dry contact devices can be wired together with Door Contact, as shown in the picture below.
The extension terminal and 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. If both the extension terminal and internal magnetic switch are in use and any of them is triggered (opened), a trigger signal will be sent to the Control Panel. The Door Contact will only send a Door Contact close (restore) signal when both of them are closed.
Battery
The Door Contact is powered by one CR123 3V Lithium battery. Please note: ALWAYS replace the battery with the correct size and voltage.
The Door Contact can detect low battery conditions. When the battery voltage is low, a low battery signal will be sent to the Control Panel to indicate the condition. The LED will light up when the Door Contact is activated under the low battery status. When the battery is exhausted, the Door Contact will stop all functions, and the LED will flash every 4 seconds.

When changing the battery, after removing the used battery, press the Tamper Switch twice to fully discharge before inserting a new battery.
Tamper Protection
The Door Contact is protected by a tamper switch which is depressed against the mounting surface when the Door Contact is mounted in place. Whenever the Door Contact cover is opened or removed from the mounting surface, the tamper switch will be activated and the Door Contact will send a tamper open signal to remind the user of the condition.
Supervisory Signal
Supervision function for 868WF model is controlled by JP2 jumper setting. For non-868WF model, supervision function is always enabled.
When 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.
Test Mode
Under Normal Mode, press the test button to transmit a test signal and a 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 period to 3 minutes.
Getting Started
Open the cover of the Door Contact and insert the battery.
Put the Control Panel in Learning Mode (please refer to the panel’s user manual).
Press the Door Contact’s test button.
Refer to your Control Panel’s user manual to complete the learn-in process.
After the Door Contact is learned-in, place the Control Panel in (Walk Test) mode, hold the Door Contact at a desired location, and press the test button to transmit a test signal to the Control Panel. If the Control Panel is within the Door Contact signal range, the panel will display the door contact information accordingly.
Proceed with mounting and installation once you are satisfied that the Door Contact functions properly at the desired location.
Installation
Installation Guideline
The Door Contact should be installed on the door/window frame, and the magnet on the door/window
The distance between the Door Contact and the magnet should be no more than 15mm when the door is closed.
Avoid mounting the Door Contact on metallic surfaces. If mounting on metallic surface is required, make sure to test whether the Door Contact can be triggered when the door is opened.
Mount the Door Contact as high as possible.
Mounting the Door Contact
Find a suitable location close to your door/window to install the Door Contact.
The Door Contact has 2 rib-marks on one side (refer to the picture below), marking the internal magnet switch location. The door contact should be installed either upright or inverted to ensure that the rib-marked side faces the magnet.
To mount the Door Contact:
Use the 2 Door Contact mounting holes as a template for appropriate hole positioning.
Use the provided wall plugs for plaster/brick installation.
Screw the Door Contact into the provided wall plugs.
To mount the Magnet:
Use the 2 magnet screw holes as a template for appropriate hole positioning.
< NOTE >
The magnet should not be more than 15 mm from the Door Contact when the door is closed.
The magnet must align with the rib-mark side of the Door Contact. If required, apply the magnet spacer to the back of the magnet to better align the magnet to the rib marks.
Screw the magnet onto the door.
Insert the two white caps into the magnet screw holes for aesthetic integrity.
