4.
Remove the magnet from its base. Line up the
arrow on the magnet with the mark on the sensor.
5.
Mount the magnet base no more than 3/8-inch
away from the sensor base. Replace the magnet
cover.
6.
Re-install the batteries and circuit board; and
attach the sensor cover to the sensor base.
Note:
When window or door construction does not
allow the transmitter to be installed next to the
magnet, install an external switch and connect it
to the Door/Window Sensor.
Connecting External Switches
External switches used with Door/Window Sensors
allow you to protect doors and windows when there is
inadequate room for directly mounting the sensor or
when you want to locate the Door/Window Sensor in
an adjacent, but less visible place.
Materials Needed
■
Hermetically sealed external switches (sealed
reed switch) that supply a minimum 250-milli-
second open or closure on alarm
■
Stranded 22-gauge wire
Installing External Switches
1.
Install the external switch according to the manu-
facturer’s instructions.
2.
Remove the cover and batteries from the Door/
Window Sensor.
3.
Feed the wires on the external switch through the
rear opening at the bottom of the Door/Window
Sensor.
4.
Attach each wire to one side of the screw termi-
nal. Press the screw terminal over the wire posts.
5.
Mount the sensor.
6.
Replace the batteries and sensor cover.
Programming
For complete programming instructions, refer to the
NX-Series Receiver Modules Installation Instructions.
Testing Door/Window Sensors
Testing sensors is recommended after all program-
ming is completed and whenever a sensor-related
problem occurs, to verify radio signal integrity and
confirm control panel programming and response.
Note:
While the sensor test is a valuable tool, it only
tests sensor operation for the current conditions.
A sensor test should be done after any change in
environment, equipment, or programming.
1.
Place the system in test mode.
2.
Trip the sensor by moving the magnet away from
the sensor and listen for the correct system
response. If the system does not respond, proceed
to the “Troubleshooting “section.
Troubleshooting
Use the following guidelines if the system does not
respond correctly when the sensor is activated.
■
Check programming and re-program sensor into
panel if necessary.
■
Use an RF Sniffer (NX-468) test tool to verify that
the sensor is transmitting. Constant beeps from
the RF Sniffer indicate a runaway (faulty) sensor.
Replace the sensor.
■
Change the position of or move the sensor to
another location and test for correct response.
To reposition a sensor:
1.
Rotate the sensor and test for improved sensor
communication at 90 and 180 degrees from the
original position.
2.
If poor communication persists, relocate the sen-
sor as described below.
To relocate a sensor:
1.
Test the sensor a few inches from the original
position.
2.
Increase the distance from the original position
and retest until an acceptable location is found.
3.
Mount the sensor in the new location.
4.
If no location is acceptable, replace the sensor.
