Product Information

The sensor can be installed on doors, windows, and many 
other objects that open and close. The sensors transmit sig-
nals to the Control Panel when a magnet mounted near the 
sensor is moved away from or closer to the sensor. The 900 
MHz Long-Life Door/Window Sensor is equipped with a wall 
and cover tamper for additional security. Extend the battery 
life of the sensor by adding a second 3-volt lithium battery.

Installation Guidelines

Use the following guidelines for installing Door/Window sen-
sors.

Mount the sensor on the door frame and the magnet on 
the door. If the sensor is to be used on double doors, 
mount the sensor on the least-used door and the magnet 
on the other door.

If possible, locate sensors within 30 meters of the panel. 
While a transmitter may have a range of 150 meters or 
more out in the open, the environment at the installation 
site can have a significant effect on transmitter range. 
Sometimes a change in sensor location can help over-
come adverse wireless conditions.

Make sure the alignment arrow on the magnet points to 
the alignment mark on the sensor.

Place sensors at least 12 cm above the floor to avoid 
damaging them.

Avoid mounting sensors in areas where they will be 
exposed to moisture or where the operating temperature 
(

0° to 49° C

) will be exceeded.

Materials Needed

#6 flathead screws

Screwdriver or brad driver

Verify Programming and Sensor-to-Panel RF 
Communication

Before mounting, verify the desired detector location pro-
vides good RF communication to the panel.

1. Put panel/receiver into sensor test mode.

2. Take sensor to desired mounting location.

3. Trip the sensor. The sensor transmits a test signal.

4. Listen for siren beeps to determine appropriate response 

(refer to the panel/receiver 

Installation Instructions

).

5. Exit sensor test mode.

To install Door/Window sensors:

1. Remove the sensor cover by pressing a small screw-

driver into the slot on the end of the sensor while lifting 
the cover.

Note

If you need to connect 
external switches, 
they should be 
installed at this point. 
See the procedure for 
connecting external 
switches in this docu-
ment.

2. Mount the sensor 

base with two #6 
flathead screws at the locations shown in Figure 2.

3. Remove the magnet from its base. Line up the arrow on 

the magnet with the mark on the narrow end or side of 
the sensor.

4. Mount the magnet base no more than 1 cm away from 

the sensor base. Replace the magnet cover.

5. Install the tamper switch as shown in Figure 3

6. Attach the sensor cover to the sensor base
