Klaxon Nexus DC Voice-Enhanced Sounder & Sounder with Beacon Installation Instructions

Installation

a. The sounder is installed by first mounting the base unit and making the external wiring 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 [quarter-turn fastener] fasteners in the corners of the sounder.

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.

Selection of the message the sounder plays is controlled by the combination of three negative supply connections as follows:

Configuration and Control

a. Messages

The sounder is supplied pre-programmed with up to seven voice messages.

A library of alternative messages can be downloaded from the relevant product page at www.klaxonsignals.com/fire. Alternative messages and tones can be installed from a Windows PC via the integrated USB interface using the voice signalling software provided on the website product page.

NOTE: The voice signalling software should be installed on the PC before the sounder is connected to the USB interface.

Custom messages can also be purchased from Texecom Ltd. Please contact Klaxon Sales on +44 (0)1706 234800 or sales@klaxonsignals.com for details.

Messages supplied by Texecom are studio recorded using the services of a professional voiceover artist and are tailored to provide optimum clarity in the sounder.

b. Message Activation

In normal operation the message will play on a continuously repeating loop for as long as power is applied to the sounder. If required, the sounder can be pre-programmed to only play the message once by setting the alerting tone to Tone 64 (see the help section within the voice signalling software).

c. Alerting Tone

If required, the type of tone and the tone volume can be changed using a PC and the USB interface.

d. Volume Control

The sound output of the unit can be reduced by adjusting the potentiometer.

e. Beacon Flash Controls (If fitted)

The flash mode of the beacon can be altered using the 2-way dipswitch marked [beacon-light].
