Installation Manual
EN
Installation
a. The sounder is installed by first mounting the base unit and making the
external wring connections to the base. The head unit then automatically
connects when it is attached to the base.
b. The sounder head is separated from the base by unlocking the four
¼-turn fasteners in the corners of the sounder.
(Recommended screwdriver: Philips No. 2, min 100mm long).
c. Note that the head only fits onto the base one way around. If a beacon
is fitted, care should be taken when mounting the base to ensure that
the beacon will be positioned in the desired orientation after the
sounder is attached
Wiring
The sounder and beacon have separate wiring terminals. Each terminal is
duplicated to enable simple 'daisy-chain' connection of multiple units.

The sound output of the unit can be reduced by up to 20dBA by
adjusting the potentiometer.
