Introduction

The VE735 and VE736 are PIR motion sensors.

They have a patented verified PIR technology.

Installation guidelines

The technology in this detector resists false alarm

hazards. Nevertheless avoid potential causes of

instability, such as:

• Direct sunlight on the detector

• Heat sources within a field of view

• Strong draughts onto the detector

• Large animals in a field of view

• Obscuring the detector’s field of view with large

objects, such as furniture

Install the detector so that the expected movement

of an intruder will be across the fields of view (see

example in Figure 21, item 1). This is the direction

best detected by PIR detectors.

Mounting the detector

1. Lift off the custom insert and remove the

enclosed screw (Figure 1).

2. Using a screwdriver, carefully prise open the

detector (Figure 2).

3. Remove the interior part (Figure 3).

4. Fix the base to the wall between 1.8 m and 3.0

m (5.9 to 9.8 ft.) from the floor. For flat

mounting, use a minimum of two screws (DIN

7998), at least one in position A and one in

position B. For corner mounting, use screws in

positions C or D (see Figures 4 and 5).

Note: Not all screw positions have pry-off

tamper. Non pry-off positions are shown in the

warning box.

5. Wire the detector. See Figures 7 and 8.

Note: All wiring must be provided according to

National Electrical Code, NFPA 70 and CSA

C22.1, Canadian Electrical Code, Part I, Safety

Standard for Electrical Installations.

Figure 16 shows a single detector wiring,

Figure 17 — multiple devices connection.

6. Select the desired jumper and DIP switch

settings (see “Setting the detector” on page 7).

Replace the interior part (Figure 9).
