Use the standard (STD) setting for wide-angle coverage and single curtain pattern. Use the bi-cur-
tain (BI) setting for added stability to help reduce false alarms. This mode requires intruders to be
detected by two curtains of coverage.

within 5 feet of the sensor.
When selecting bi-curtain

You must be free of static electricity before handling circuit boards. Wear a
grounding strap or touch a bare metal surface to discharge static electricity.

Walk Testing
Walk testing should be done to determine the actual coverage area of the sensor. The edge of the
coverage pattern is determined by the first LED flash. This may change slightly depending on the
sensitivity setting. Walk test the unit from both directions to determine the pattern boundaries.
coverage pattern is determined by the first LED flash. This may change slightly depending on the
sensitivity setting. Walk test the unit from both directions to determine the pattern boundaries.
1. Remove the sensor cover to activate the tamper switch, then reattach it to activate the 2-
minute walk test mode.
2. Walk across the coverage pattern to determine the coverage area, indicated by LED activation.
After 2 minutes, the walk test mode and the LED will no longer activate when motion is detected.
Note
Excessive use of the walk test mode may reduce battery life. Use only for initial setup and maintenance
testing. In normal operation mode, the sensor only transmits an alarm signal 135 seconds after the pre-
vious alarm. This reduces unnecessary RF transmissions in high traffic areas, thereby extending battery
life.
