The Door/Window Sensor (60-362) and Long Life Door/
Window Sensor (60-641) can be installed on doors, win-
dows, or virtually anything that opens and closes. During 
normal operation, the sensors transmit open (TRIP) and 
close (RESTORE) signals to the panel. The sensors also 
send a supervisory signal to the panel every 64 minutes.

Sensors transmit open and close signals to the panel when a 
magnet (mounted near the sensor) is moved away from or 
closer to the sensor.

The sensors are powered by a 3.6-volt lithium battery. 

 œÌi

The Long Life Door/Window Sensor battery cannot be 
replaced by installers or users. If you receive a low 
battery report, you must return the sensor to ITI for 
replacement.

q #6 flathead screws or 18-gauge brads
q Screwdriver or brad driver 
q Small wire cutters
q Sensor and magnet spacers (optional)

q Keep all sensors within 100 feet of the panel. 
q 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.

q Mount sensors with screws or brads, not double-sided 

tape.

q Place sensors at least 5 inches above the floor to avoid 

damaging them.

q Use spacers (not included) to keep sensors and magnets 

away from metal or metallic surfaces such as foil wall-
paper.

q Remove the internal reed switch not being used.
q Avoid mounting sensors in areas with a large quantity 

of metal or electrical wiring, such as a furnace or utility 
room.

q Avoid mounting sensors in areas where they will be 

exposed to moisture.

q Avoid mounting sensors in locations where the operat-

ing temperature (10° to 120° F) will be exceeded.

1/" 

Do not remove the jumper from the Long-Life Door/
Window Sensor circuit board! The sensor cannot work 
without the jumper.

1/" 

You must be free of all static electricity when handling 
electronic components. Touch a grounded, bare metal 
surface before touching a circuit board or wear a 
grounded wrist strap.

1.

Decide if the sensor should be mounted horizontally or 
vertically by locating the alignment marks on the sen-
sor and magnet plastic (see Figure 1.)

The marks indicate reed switch locations. Each sensor 
uses only one of the two switches. You will remove the 
unused one in step 4.

2.

Remove the sensor cover by squeezing the cover ends 
firmly to release the tab on the cover from the slot on 
the sensor base.

3.

Remove the circuit board from the sensor base by pull-
ing back the plastic tab and lifting the battery to release 
the circuit board.
