Installation Sheet
Enrolling
To enroll the sensor, set your panel into program mode. Then go to the Learn Sensors menu. Refer to your
specific alarm panel manual for details on these menus. When prompted by the panel:
• Touch the magnet to the side of the sensor that has three white lines. This will send a signal to the control
panel using the serial number printed on the back of the sensor. OR
• Connect the provided external wire, and short the wires together.
• Select the appropriate sensor group and number
Note
: You cannot use both the external wire input and the magnet/reed switch at the same time. When using
the magnet, the external wires must be disconnected.
Mounting
One side of the sensor is marked with 3 lines; this indicates the location of the reed switch. The magnet should
be mounted facing this side of the sensor, and be
no further than 5/8” (15.875mm) from the sensor.
Included with this device is double sided tape for the contact and the magnet. Choose a suitable location for the
sensor by following the procedure in the section “Testing the Sensor” ensuring desired signal strength is
achieved
.
For reliable bonding, ensure the surface is clean and dry. Apply the tape to the sensor and then to the
desired location. Apply firm pressure for several seconds.
Note:
When mounting with double sided tape, ensure temperatures are above 50°F and will remain above 50°F
for at least 24 hours to ensure proper bond. After 24 hours, the bond will hold at lower temperatures.
In addition, a mounting back plate with screws is provided. Simply screw the back plate onto the mounting
surface and snap the sensor onto the mounting plate.
To remove the sensor from the mounting plate, first remove the cover. At the bottom of the sensor (closest to
the battery) a small tab will be visible. Use a small flat head screwdriver to press the plastic tab towards the wall,
and then slide the sensor up.
Note
: Do not use the tape to secure the mounting plate to the wall.
Where possible, install sensors within 100 ft. (30 m) of the panel. While a transmitter may have an open-air
range of 500 ft. (150 m) or more, the environment at the installation site may have a significant effect on
operational range. Changing a sensor location may improve wireless communication.
Interchangeable Covers
The contact comes from the factory assembled with a white cover, but included is an optional brown cover. To
change the cover, slide the front cover to disengage it from the sensor then remove. Replace with the desired
cover ensuring the Top (as marked on the inside of the cover) points away from the battery. You should hear a
click when the cover engages and disengages from the sensor. You do not need to replace the back plastic
because once mounted the back is not visible. To replace the magnet cover you will need to gently pry the white
cover off with a flat head screw driver and snap the brown cover in place.
Installing / Replacing the Battery
When the battery is low, a signal will be sent to the control panel. To replace the battery:
1. Slide the top cover to disengage it from the sensor. Then remove it to reveal the battery.
(Removing the cover will trigger a zone tamper signal to the control panel.)
2. Install / replace with a CR2032 battery ensuring the + side of the battery faces towards you.
3. Re-attach the cover. Ensure the Top (as marked on the inside of the cover) points away from the battery.
You should hear a click when the cover engages properly.
Testing the Sensor (Test Weekly)
The sensor test verifies proper communication between the sensor and the panel/receiver. To test the sensor,
refer to the specific panel/receiver documentation and do the following:
1. Put the panel/receiver into sensor test mode.
2. Open the door/window the sensor is protecting. The sensor transmits a signal.
3. Listen for siren beeps to determine the appropriate response.
4. Exit sensor test mode.
