Setting the Sensor Coverage Area and Sensitivity
Setting the Sensor Coverage Area
and Sensitivity
Jumper J1 determines the sensitivity mode of the sensor,
either standard or bi-curtain. Jumper J2 determines the cov-
erage area of the sensor, either 33 or 50 feet. See Figure 7
for jumper positions.
Use the standard (STD) setting for wide-angle coverage and
single curtain pattern. Use the bi-curtain (BI) setting for
added stability to help reduce false alarms. This mode
requires intruders to be detected by two curtains of cover-
age.
1RWH
Do not use the bi-curtain mode for detection in areas
within 5 feet of the sensor. When selecting bi-curtain
mode, always leave the cardboard undercrawl mask
installed.

You must be free of all static electricity before handling
sensor circuit boards. Touch a grounded, bare metal
surface before touching circuit boards or wear a
grounding strap.

Walk Testing
Walk testing should be done to determine the actual cover-
age 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.
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 cov-
erage area, indicated by LED activation.
After 2 minutes, the walk test mode and the LED will no
longer activate when motion is detected.
1RWH
Excessive use of the walk test mode may reduce bat-
tery life. Use only for initial setup and maintenance
testing.
1RWH
In normal operation mode, the sensor only transmits
an alarm signal 135 seconds after the previous alarm.
This reduces unnecessary RF transmissions in high
traffic areas, thereby extending battery life.
Environment Testing
Activate the walk test mode, then turn on all heating or air
conditioning sources which would normally be active dur-
ing the protection period. Stand away from the sensor and
outside the coverage pattern and watch for alarms.
Installing Masks
After determining the full coverage area and performing the
environment test, you may need or want to mask (block)
certain parts of the coverage.
Self-Adhesive Masks
Block the appropriate mirror sections with these masks.
Figure 8 shows an example of where to apply the masks and
the resulting coverage area.
&$87,21
To avoid damaging the mirror, do not remove masks
using a sharp tool. If necessary, remove masks by
carefully peeling them off with your fingers.
