Installation:

Observe anti-static precautions at all times
1. The sounders may be secured to a standard
conduit box or surface mounted if there is access
through the mounting surface for cabling. If a
detector is fitted, lock it if required by screwing in
the grub screw on the detector head with a 1. 5mm
hex driver.

Standard Sounder Wiring:

1. The sounders are polarity sensitive (supply
reversal protected) and will not function if wired
incorrectly.
2. Observing polarity connect the positive and
negative loop cables to the L2 and L1 terminals
respectively. The wiring terminals accept solid or
stranded cables up to 2.5mm². Functional earth or
screen cables may be terminated to the EARTH
connection. ( See Figure 1)

Address Setting:

The address of the sounder is set using seven
segments of the eight- segment DIL switch. The eighth
segment is used to adjust the sounder output level.
Segments 1- 7 of the switch are set to "0" (ON) or "1",
using a small screwdriver or similar tool. A complete list
of address settings is shown in on Page 3. If a detector
is to be fitted, set the Xpert Card address as described
on Page 2.
