The Nexus 105 DC Sounder & Sounder-Beacon is a device that produces different tones to alert people in case of emergency situations. It has 64 different tones that can be selected using dip switches S1/S2. The device requires a 24V DC power supply.
Product Usage Instructions
- Connect the device to a 24V DC power supply.
- Select the desired tone by adjusting dip switches S1/S2.
- Test the device to ensure it is producing the correct tone and sound level.
- Mount the device in a suitable location where it can be heard by people in case of an emergency.
Tone Description / Application
Installation
-
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.
-
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). -
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.
Controls
-
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. -
Volume Control
The sound output of the unit can be reduced by up to 20dBA by adjusting the potentiometer. -
Beacon Flash Controls (If fitted)
The flash mode of the beacon can be altered using the 2-way dipswitch marked | XENON BEACON LED BEACON
