Installation Guidelines
■
Do not use solid core wire.
■
Do not use mechanical switches.
■
If you are connecting an external device to a door/
window sensor, do not use the built-in reed
switches.
■
Do not connect fast pulse devices (such as Win-
dow Bugs) to door/window sensors.
■
Do not use more than 25 feet of 22-gauge,
stranded wire in any wire run.
■
Do not use more than 6 feet of untwisted wire in
any wire run.
■
Do not connect more than five switches, or more
than one alarm screen to a door/window sensor.
■
Do not run wires parallel to electrical wires. If
you can’t avoid a parallel wire run, keep it at least
18 inches away from electrical wiring.
■
If necessary, you may cross electrical wires at a
90 degree angle.
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.
To replace a sensor:
1.
Test a known good sensor at the same location.
2.
If the system does not respond, avoid mounting a
sensor at that location.
3.
If the replacement sensor functions, return the
problem sensor for repair or replacement.
