VWLS100-AV
ANALOGUE WATERPROOF AUDIOVISUAL WALL SOUNDER
For specific information regarding detector and device’s spacing, placement and special applications refer to your specific
national or international standard codes of practice.
This device must be used in conjunction with a compatible control panel employing the Vega communication protocol for
monitoring and control.
GENERAL DESCRIPTION
This visual-acoustic output device is activated by a specific command sent from the analogue control panel, in case of fire or emergency situations; the communication between the sounder-beacon and the control panel is through the analogue ’Vega’ protocol.
This device draws power directly from the analogue loop, therefore there is no need for an external additional power supply source.
This device provides a mixed United Kingdom and European five tone set: the installer can set one of them manually and solely on
the device itself; similarly, sounder volume can be set solely by directly and manually acting on the device. Beacon’s flash rate and
intensity is fixed. During active operation, groups of sounders can have their acoustic outputs synchronized (if the control panel is
implemented with such feature).
TECHNICAL SPECIFICATIONS
During device’s cabling, remember that connections to the terminals are polarity sensitive: so, please, check them by
referring to the wiring information given in this manual.
Disconnect loop power before installing the devices.
CABLE ENTRY
Device’s wall box is designed to allow either rear or side cable entry.
To the rear a central knockout allows cable entry whilst a selection of screw fixing points provide for either surface or electrical box
mounting.

WARNINGS AND LIMITATIONS
Our devices use high quality electronic components and plastic materials that are highly resistant to environmental deterioration.
However, after 10 years of continuous operation, it is advisable to replace the devices in order to minimize the risk of reduced
performance caused by external factors. Ensure that this device is only used with compatible control panels. Detection systems
must be checked, serviced and maintained on a regular basis to confirm correct operation.
Smoke sensors may respond differently to various kinds of smoke particles, thus application advice should be sought for special
risks. Sensors cannot respond correctly if barriers exist between them and the fire location and may be affected by special environmental conditions.
Refer to and follow national codes of practice and other internationally recognized fire engineering standards.
Appropriate risk assessment should be carried out initially to determine correct design criteria and updated periodically.
WARRANTY
LOOP TERMINAL
BLOCKS
All devices are supplied with the benefit of a limited 3 year warranty relating to faulty materials or manufacturing defects, effective
from the production date indicated on each product.
This warranty is invalidated by mechanical or electrical damage caused in the field by incorrect handling or usage.
Product must be returned via your authorized supplier for repair or replacement together with full information on any problem identified.

Main application
Analogue wall sounder-beacons must be addressed by using a special hand-held programming unit (consult its manual for more
data) or they can be auto-addressed by the control panel (if the control panel possess such feature).
Addresses must be selected within a range from 1 to 240 and each device on the loop must have a unique address.

TESTING
In order to test the functionality of the installed sounder-beacon, the following test must be performed: activate an alarm condition on
the control panel (by a call-point or sensor in the installed system): the control panel will activate the device’s output.
After each test the device must be reset by the specific command on the control panel (see the RESET paragraph).
If the test fails, check if mistakes were done previously or even if the system is powered on. If the device’s functionality is hopeless,
send back the device to your distributor for repair or substitution.
All devices must be tested after installation and, successively, on a periodic basis.
++--
RESET
To reset the sounder-beacon device from an activated condition or a functional fault (raised and indicated by the control panel
solely), it is necessary to:
1) solve the cause of the abnormal condition
2) send the reset command from the control panel.
LOOP IN (POSITIVE)
LOOP OUT (NEGATIVE)
Performing sequentially those two operations, the acoustic-visual output and/or fault condition will deactivate / resolve.
MAINTENANCE
LOOP IN (NEGATIVE)
LOOP OUT (POSITIVE)
SHORT CIRCUIT ISOLATOR
All standard Vega series devices are provided with integrated short circuit isolators which monitor the detection loop and can also be
activated by the control panel.
VOLUME REGULATION
This device is provided with a volume control switch, accessible under the PCB cover at the rear of the device (picture
5). Carefully release one of the side catches on the PCB
cover and remove it, then switch over, with the aid of the tip
of a pen or screwdriver, the first rightmost switch (picture
10). The switch, if set inwards the device, gives the highest
volume, while, if set outwards, gives the lowest volume (see
the TECHNICAL SPECIFICATIONS).
The volume can be adjusted in this way to match the application conditions.
1) Before starting any maintenance work, isolate and disable the system, in order to avoid accidental and unwanted fault detection
conditions.
2) Remove the sounder-beacon from its wall base.
3) Perform the planned necessary maintenance operations.
4) After the device has been serviced, reinstall correctly and securely the sounder-beacon block onto its wall base, re-apply
power to the system and check correct operation as described under the TESTING paragraph.

setting switches
In order to select the sounder-beacon sound output, switch
over, with the aid of the tip of a pen or screwdriver, the first three switches (beginning from the left side) positioned under the PCB
(see picture 5 and 10).
Select the desired tone by referring to table 1 and changing over the switches as thereby specified: the first indicated digit in the
sequence symbolizes the switching status of the leftmost one, and the successive ones are those that follow in physical sequence
(“Switches position” column of the table); value “0” means that the considered switch must be set outwards the device; value “1”
means that the considered switch must be set inwards the device.
