4. Installation.
Pre-installation at Ground Level.
Confirm that all parts have been supplied as listed in the parts list. See page 9.
Select the required alarm threshold using switches 3 and 4 (See fig. 4. for switch configuration settings). The
factory default setting is 35% this should be adequate for most environments, if the Detector is to be installed
into an exceptionally dirty environment change the threshold to 50%.
The Detector Head Assembly is now ready for installation. If switches 3 and 4 require resetting after installation,
a power down reset is required (entering into Alignment Mode can also be used as a reset).
4.1. Detector Head Assembly Installation.
Remove the outer cover before installation; this is only to prevent the cover becoming dislodged during
handling.
Do not mount on plasterboard or cladded walls as these surfaces do, and will move.
Determine the position of the Head Assembly, which must be mounted on a solid structure between 0.3 and
0.6 metres below the ceiling, and no closer than 0.5 metres to an adjacent wall or structure. Ensure that there is
a clear line of sight to the proposed position of the prism(s), which is to be mounted on a solid structure
between 5 and 100 metres directly opposite the Detector (range dependent on model).
Using the template provided mark and install all 4 fixing points to the structure. The rear mounting plate of the
Detector Head Assembly is provided with 4 keyhole slotted apertures to allow for easy installation onto the 4
fixing points.
Replace the outer cover.
Terminate the field wiring. See section 8.
4.2. Prism(s) Installation.
Due to the principle of the detector i.e. reflective, the prism(s) must NOT be mounted on glass or a
polished reflective surface.
Mount the Prism(s) on a solid structure, 90º to the beam path, between 5 to 50 metres (for the 50 metre
detector), and 50 to100 metres (for the 100 metre detector) directly opposite the Detector.

metre
detector
Ensure that there is a clear line of sight to the Detector, taking care that no moving objects i.e. doors,
mechanical lifting equipment etc, will interfere with the beam path between the Detector and Prism(s).
Note: On ranges of ≥5 metres and ≤50 metres use a 50 metre detector.
On ranges of ≥50 metres and ≤100 metres use a 100 metre detector.
