NX-450, NX-451 Door/Window Sensors
Installation Instructions
Product summary
The NX-450 (white) and NX-451 (brown) Door/Window
Sensors (60-670-95R) 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/window contacts

Installation
Installation guidelines
• Mount the sensor on the door frame and the magnet on
the door (see Figure 2 below). If the sensor is to be used
on do
uble doors, mount the sensor on the least-used door
and the magnet on the other door.
• If possible, locate sensors within 100 ft. of the panel. While
a transmitter may have a range of 500 ft. 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 overcome adverse
wireless conditions.
• Make sure the alignment arrow on the magnet points to
the alignment mark on the sensor (see Figure 3 below).
•
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.
