TX-E721 PET Immune PIR Motion Detector Installation Sheet 3 / 4
Important information Regarding Sensitivity Settings
The sensitivity settings should be set as followed:
Standard Sense:
 Rooms < 25ft
 Pets < 40 pounds
High Sense:
 Rooms < 35ft
 Pets < 20 pounds
Testing
Walk Testing
Walk testing should be done to determine the sensor’s actual coverage
area. The edge of the coverage pattern is determined by the first flash of the
LED. This may change slightly depending upon the sensitivity setting. Walk
test the unit from both directions to determine the pattern boundaries.
CAUTION: Excessive use of the walk test mode may reduce battery
life. Use only for initial setup and maintenance testing.
1. Remove the sensor body from the mounted mounting plate and then
remount the body to activate the 60 second walk test mode.
2. Walk across the coverage pattern to determine the coverage area,
indicated by LED activation. Each activation extends the walk test
mode for an additional 60 seconds.
After 60 seconds without motion the walk test mode and the LED will no
longer activate when motion is detected.
Note: When the walk test mode has ended, an alarm can be transmitted
only after 3 minutes have passed since the previous alarm. This 3 minute
lockout time reduces unnecessary RF transmissions in high traffic areas
thereby extending battery life.
Environment Testing
Turn on all heating or air conditioning sources which would normally be
active during the protection period. Stand away from the sensor and outside
the coverage pattern and watch for alarms. When testing the Pet Immune
PIR also verify the pets allowed in the coverage pattern do not trip the PIR.
Maintenance
At least once a year, the range and coverage should be verified for proper
operation. The end user should be instructed to put the sensor in walk test
mode and walk through the far end of the coverage pattern to verify proper
detection.
Replacing the Battery
When the system indicates the sensor has a low battery, replace the battery
immediately.
1. Remove the mounting plate by depressing the button on the top of the
sensor body. With the opposite hand pull the mounting plate away from
the body of the sensor. See Figure 8.
2. Remove the old battery and replace with new battery (CR123A)
Note: Observe polarity when replacing the battery. The battery should
be inserted with the negative end closest to the left side of the PIR
when viewing it from the back. The positive end of the battery should
be closest to the right side. See Figure 8.
If a battery is installed incorrectly the unit will not function and
the red LED will not light up. The sensor may be damaged if a
battery is installed incorrectly.
3. Dispose of the battery as required by local requirements
4. Walk test the PIR to verify proper operation.
Note: When the battery is replaced, wait at least three minutes after
installing the battery before activating the walk test mode.

Troubleshooting
Use the following guidelines if the system does not respond correctly when
the sensor final testing is conducted.
• Check programming and re-program sensor into panel if necessary.
• Move the sensor to another location and test for correct response.
• Check the mounting height and angle are according to “Mounting”
section.
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, test the sensor as described below:
• Test a known good sensor at the same location.
• If the system does not respond, avoid mounting a sensor at that
location.
• If the replacement sensor functions, return the problem sensor for
repair or replacement.
