The sensor has two areas, right and left, and each area has two zones of detection — the horizontal zone and
the downward zone. The system initiates an alarm when detection occurs in both of these in a same area
simultaneously. If changes in temperature occur to the left and right area in different zones simultaneously,
(e.g. the left horizontal zone and the right downward zone), this will not be interpreted as detection.

Detection distance is set by adjusting the angle of downward zone.
Adjustable range 10' (3m) to 40' (12m). [9 ranges]
Downward Zone
[SIDE VIEW]
Adjusting the detection distance adjustment holder position up and down
changes the detection distance. (The detection distance can be changed
between 10' to 40' (approx. 3m to 12 m)
(1) Remove the cover.
(2) Loosen the detection distance adjustment holder locking screw.
(3) Referring to the index, move the holder up to move the detection
distance closer, and down to move the detection distance further away.
(4) Tighten the locking screw to set the detection distance.
