KLAXON Nexus DC Voice Enhanced Sounder and Sounder with Beacon
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.
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.
| Line | Terminal Marking |
|---|---|
| Sounder Positive Supply (17 to 28VDC) | + |
| Sounder Negative Supply (0V) | – |
| Sounder Negative Supply (0V) | S2 |
| Sounder Negative Supply (0V) | S3 |
| Beacon Positive Supply (17 to 28V DC) | + |
| Beacon Negative Supply (0V) | – |
Selection of the message the sounder plays is controlled by the combination of three negative supply connections as follows:
| Connections to Supply Negative | Message |

| S3 | S3 |

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 .
