EN 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 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.

Controls

a.Tone Selection

The first and second stage alarm tones are independently set using 6-way dipswitches S1 and S2 respectively. The required settings are shown in the table overleaf. The third stage alarm tone is pre-set to complement the selected first stage tone as shown in the table.

b.Volume Control

The sound output of the unit can be reduced by up to 20dBA by adjusting the potentiometer. At low sound levels the sound may take a few seconds to decay away after power is removed from the sounder.
