4. Installation.

Pre-installation at Ground Level.

Confirm that all parts have been supplied as listed in the parts list. See page 10.

Select the required alarm threshold using configuration switches 3 and 4 (See page 8, 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%.

Select the required address using address switches 1 to 8 (See page 9, Table 1. for address switch settings)

where 1 is 'ON' and 0 is 'OFF'. The lower nibble (bit 1 to 4) is a BCD value and the upper nibble (bit 5 to 8) is a

HEX value. The factory default setting is address1.

Shown below is an example of address 55 (1+4+10+40 = 55).

Switch Position

The Detector Head Assembly is now ready for installation. If configuration 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. Install the detector on the four mounting 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 (Fireray FD2705R),

and 50 to100 metres (Fireray FD2710R) directly opposite the Detector.

FD2705R =

1 Prism

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 FD2705R.

On ranges of 50 meters and 100 meters use a FD2710R.
