Door Contact (DC-23 / DC-23-R3) User Manual

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.

DC-23 Series Door Contact includes following models:

DC-23: Door Contact cover is secured by a bottom fixing screw.

DC-23-R3: Door Contact cover is secured by two latches at top and bottom

Parts Identification

1. LED indicator / Test button

Press the Test button to transmit learning code or enter test mode

Features



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.



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 is 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:

1. Open the Door Contact’s cover by using a screwdriver to loosen the cover fixing
screw at the buttom of the Door Contact’s cover. (See picture below picture from
upper view angle).

2. 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.

3. Connect the device to the extension terminal

For DC-23-R3 model:

4. Use your thumb to press on the Latch, while pressing it, pull out the cover from the
base of the Door Contact (see below picture from upper view angle).

5. 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.

6. 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 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.



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
extension terminal and internal magnetic switch is in use and any of them is triggered (opened). The Door Contact will
only send 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 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 battery, after removing the old batteries, press the Tamper Switch twice to fully discharge before
inserting new battery.



Tamper Protection



The Door Contact is protected by a tamper switch which is compressed against the mounting surface when the Door
Contact is mounted. Whenever the Door Contact cover is opened, or removed from mounted 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.
