Door Contact (DC-15) 433M
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. An internal magnetic switch activates when the
corresponding device magnet is present or not transmitting device status 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.

In Normal Operation Mode, the LED will not light except in the following situations:
z When the Door Contact is in Low battery condition, every time the Door Contact is activated (device opened/
closed), the LED will light.
z When the cover is opened and the tamper switch is violated, the LED will light.
z When a tamper condition persists, every time the Door Contact is activated, the LED will light.
However, if the Device Contact is in Test mode, the LED will flash every time it is activated.

It is recommended that the Door Contact should be placed on the door frame and the
magnet on the door. If the door contact is placed on the door.
Step 1: Find a suitable location close to your door/window to install the Door Contact.
Step 2: The Door Contact has 2 rib-marks on one side (refer to figure), marking the
internal magnet switch location. The door contact should be installed either
upright or inverted, to ensure that the rib-marked side face the magnet.
Step 3: To mount the Door Contact:
(i) Using the 2 Door Contact mounting holes as a template for appropriate
hole positioning.
(ii) Use the provided wall plugs for plaster/brick installation.

(iii) Screw the Door Contact into the provided wall plugs.
Step 4: Fit the magnet on the door using the small piece of double sided adhesive tape or with provided screws. The
<< NNOOTTEE >>
magnet must align
with the 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.
Step 5: Put the Control Panel into (Walk Test) Mode, and press the Test Button on the Door contact. This enables the
LED indicator to flash every time the Door Contact is operated.
Step 6: Fit the white caps to the two mounting holes of the Door Contact.
Step 7: Installation is now complete.

The Door Contact has an Extension Terminal providing enhanced installation flexibility.
The Extension terminal may be useful for the following:
z If the Door Contact cannot be mounted on the door frame, you can connect an
additional (extension magnet switch) to the (Extension Terminal) mounting
the Door Contact remotely.
z More than one window and door can be protected by a Door Contact using the
additional magnet and extension magnet switch. The switches must be wired to
the (Extension Terminal) as shown:
z Any dry contact device with N.C. (Normally Closed), such as a Broken Glass
detector, Smoke Sensor, Gas detector, Water Sensor etc, can be connected to
the (Extension Terminal) making the Door Contact serve as an (Universal
Transmitter).

) The Extension Terminal forms a closed loop with the device connected to it. W hen the
Loop is opened (the device is triggered), the Door Contact is activated.
) The device connected to the Extension Terminal is in series with the internal magnet Switch. Meaning both
can work together simultaneously.
) You can choose to use the Extension Terminal alone with the internal magnet switch bypassed or to use both
together.
) If both the Internal Magnet Switch and Extension Terminal operate together, then:
