Installation Manual

Installation

a. The sounder is installed by first mounting the base unit and making the external wring connectionsto the base. The head unit then automatically connectswhen it is attachedto 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.
