3. Where possible, mount the detector so that the logical path of an intruder
would cut across the fan pattern rather than directly towards the detector.

4. For best results, locate the detector directly facing entrance. (FIGURE 4)

Installation
The unit can apply to two installations. Select a location for the unit based on
the coverage angles shown in FIGURE 6b and FIGURE 7b. To install a detector:
1. Undo and remove the screw from the bottom edge of the detector to detach
the rear cover. (FIGURE 5a)
2. Insert 3 AA-size 1.5V alkaline batteries to the battery compartment, ensuring
that correct polarity is put. (FIGURE 5b)

3. Decide the detector is to be wall-mounted (FIGURE 6a) or ceiling-mounted
(FIGURE 7a). Hold the rear cover in position and mark the two mounting
holes. Drill the holes, insert the plastic wall plugs and screw the rear cover
to the wall or ceiling using the screws supplied.
4. Engage the detector to the rear cover firmly.
(1) Wall Mounting
The recommended position for wall mounting is at the height of 1.8m (5.91 ft)
from the floor. At this height, the optimum detection range is up to 10m
(32.81 ft) with coverage range of 110 degrees (FIGURE 6b).

(2) Ceiling Mounting
The recommended position for ceiling mounting is at the height of 2.8m
(9.19ft) from the floor. At this height, the optimum detection range is up to
5m (16.41ft) with coverage range of 360 degrees (FIGURE 7b).
