To reposition a sensor:
1. Rotate the sensor and test for improved sensor communications at 90 and 180
degrees from original position.
2. If poor communication persists, relocate the sensor.
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 transmission beeps remain below the minimum level, avoid mounting a
sensor at that location.
3. If the known-good sensor functions, contact UTC Fire & Security for repair or
replacement of the problem sensor.

within 10 minutes.
If the test is unsuccessful:
1. Check that the panel is connected to the phone jack.
2. Check the phone number programmed into the panel.
3. Perform the communication test again.
