To adjust the PIR detection pattern toward or away from the
door opening, do the following:
1. Open the sensor cover; see “Figure 1: Open the cover”
on page 1 and loosen the PCB axle screw (Figure 11).
Figure 11: PIR Pattern Adjustment
2. Rotate the PCB to the desired position and tighten the
PCB axle screw. Table 2 gives the suggested angle for
a given mounting height.
Table 2: Suggested Angles
3. Close the cover.
4. Test to be sure undesired sources of motion will not be
detected.
Radar Detection Pattern
Figure 12 shows the radar detection pattern.
Figure 12: Radar Detection Pattern
You can adjust the radar range from 3 to 15 ft. (0.9 to 4.57
m). To adjust the range, rotate the range adjustment control
(Figure 13) to the desired position. The radar range is not
affected by the PCB rotation during PIR range adjustment.
The radar range can be set to just above the floor, to prevent
door activation from objects that have been slipped under
the door. After adjusting the radar range, carefully test to be
sure undesired sources of motion will not be detected.

Operation
By connecting the lock relay in series with the door lock and
the monitor relay in parallel to the door switch and alarm
circuit, the sensor will allow normal egress and will monitor
alarms from the door being held or forced open. The sensor
will monitor the operation of the door switch without affecting
the access control system.
When the sensor detects motion, the lock relay contacts
open, unlocking the door, and the monitor relay contacts
close, preventing an alarm from being sent to the access
control system for a fixed time. The time is selected with the
DIP switch from 1/2 to 64 seconds or until reset by the
sensor. See DIP switch options on page 4.
If the sensor does not detect the opening of the door switch
within 10 seconds of sensor activation; the lock and monitor
relays will return to their normal condition. If the relay timer is
set to 8 seconds or shorter, the lock relay will change back
to the normal condition when the relay timer times out. After
the door switch opens and closes, the sensor will
automatically cancel any remaining relay time if the door
switch remains closed for at least 2 seconds.
The sensor’s sounder will produce a continuous tone to warn
of an open door 15 seconds before the timer closes the lock
relay contacts and opens the monitor relay contacts. Closing
the door will silence the sounder. New movement within the
detection area will restart the timer and reset the sounder. If
the door is still open when the timer ends, the monitor relay
contacts will open, which will cause an alarm signal to be
sent to the access control system.
