Product Summary

The NX-450 (white) and NX-451 (brown) Door/Win-

dow Sensors can be installed on doors, windows, or

many other objects that open and close. The sensors

transmit signals to the control panel when a magnet

mounted near the sensor is moved away from or closer

to the sensor.

The sensors include an input that accepts external

hardwired devices such as flush-mounted door/win-

dow contacts.

Installation Guidelines

Use the following guidelines for installing Door/Win-

dow sensors.

Mount the sensor on the door frame and the mag-

net on the door (see Figure 1). 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.

Figure 1. Sensor and Magnet Locations

If possible, locate sensors within 100 feet of the

panel. While a transmitter may have a range of

500 feet or more out in the open, the environment

at the installation site can have a significant effect

on transmitter range. Sometimes a change in sen-

sor location can help overcome adverse wireless

conditions.

Make sure the alignment arrow on the magnet

points to the alignment mark on the sensor (see

Figure 2).

Figure 2. Aligning the Door/Window Sensor

and Magnet

Place sensors at least 5 inches above the floor to

avoid damaging them.

Avoid mounting sensors in areas where they will

be exposed to moisture or where the operating

temperature (10°-120°F) will be exceeded.

Use spacers (not included) to keep sensors and

magnets away from metal or metallic surfaces

such as foil wallpaper.
