11.0 Optical Module Adjustment

• The PIR zones of the DS9370 are divided into three groups. Each of these 3 groups can be independently adjusted vertically to

provide the best coverage within a room.

Only two coverage patterns are shown for clarity. PIR vertical adjustment knobs

• Use the following chart to adjust the optical modules based on the mounting height of the detector. The range shown is the distance

from the detector to the outside edge of the coverage pattern.

• In installations where a targeted coverage is required for part of the area, the optical modules must be adjusted for the correct

coverage. In the example below, the detector is mounted 12 ft. (3.7 m) above the floor. The distance to one wall is 20 ft. (6.1 m) and 35

ft. (10.7 m) to the opposite wall. Using the chart above, the optical module for the 20 ft. (6.1 m) range was set to "D" and the optical

module for the 35 ft. (10.7 m) was set to "I".

Only two coverage patterns are shown for clarity.
