Selectable Operation Modes
The detector operates in two operation modes. In Directional Mode, crossing the infrared beams is
alarm‐protected in one direction only. The protected direction is shown by the arrow printed on the
PCB. In case of crossing the beams from the non‐permitted side (ALARM), red LED is lit for a
second. In case of crossing the beams from the permitted side (NO ALARM), green LED is lit for a
second and the Alarm delay (see below) starts to count down. In Curtain mode, crossing the beams
is alarm‐protected in both directions. The Operation mode (Directional/Curtain) is selected using
the Mode Jumper – see Table B‐3.
Alarm Delay
The Alarm Delay is a feature designed to allow the occupant to move freely within the protected area
without triggering a false alarm. When approaching the protected wall, an alarm is not generated
because the detector's beams are crossed from the permitted direction. After detecting permitted
motion, the detector counts down the Alarm Delay time. This timer is re‐triggered every time the
detector detects motion. During the Alarm Delay, the detector permits motion in both directions. The
duration of the alarm delay is selected using the Alarm Delay Jumper – see Table B‐4.
