VADS FIRE ALARMS – VISUAL ALARM DEVICES (EN54-23 COMPLIANT)

FPG-VADsAlarms

Visual Alarm Devices (VADs) are an essential component to most fire alarm systems. They provide a visual indication of an alarm condition to those people who wouldn’t normally be alerted to a fire by standard audible-only devices, such as sounders and bells.

The Disability Discrimination Act of 1995 made the inclusion of VADs mandatory in all public buildings, specifically in areas where people with impaired hearing work in isolation. But VADs are also required in noisy environments where staff might be wearing ear defenders such as factories, foundries etc.

A new product standard, BS EN 54-23:2010 (Fire detection and fire alarm systems. Part 23: Fire alarm devices – Visual alarms devices), has been introduced primarily to standardise the requirements, test methods and performance of VADs and ensure their light output is measured in a uniform manner. This standard will be mandatory throughout Europe from 31st December 2013 and all manufacturers of VADs will be affected.

KEY FEATURES OF THE RANGE

  • The new Wall and Ceiling Beacons in our new EN54-23 compliant range are available with either red or white LEDs offering additional flexibility to the end-installer when deciding on the requirements of each installation
  • The EN54-23 ratings of these Beacons (the brightness of the LEDs – which affects the area that is illuminated) can be adjusted on each model from the control panel. This reduces the number of devices required in the range as each one can produce up to three different ratings making it easier to choose the right VAD for the task.
  • The circuitry in our new Wall and Ceiling Beacons is continually monitored to ensure that it is still functioning. A malfunctioning device will show at the panel as a fault saving time and effort on maintenance inspections.
  • When in operation, these Beacons monitor the LED light output via a separate sensor to ensure that a flash occurs, again saving time on scheduled walk-tests. A failure to operate is indicated as a fault at the panel, depending on panel compatibility.
  • The control panel can be programmed to perform an automatic daily LED check on our Wall and Ceiling Beacons, consisting of a lower power single flash, recorded by the in-built sensor. This reduces the probability of a failure on demand, just when the device is needed. A failure is indicated at the panel, depending on panel compatibility.
  • Our new Wall and Ceiling Beacons have the ability to be powered externally from a separate 24V power supply. This means for projects that require many VADs the loop current isn’t drained by the LEDs when they are activated (meaning more devices on the loop is possible). This is dependant on panel compatibility
  • Custom-designed lens
  • LED technology
  • Outdoor variants available (used with the wall sounder weatherproofing kit)
