Hyfire Visual Alarm Device VAD’s
The wireless fire alarm range Hyfire from Sterling Safety Systems now has an approved EN54-23 VAD, which is short for Visual Alarm Device.
If we go back and review the audio-visual alarms over the last ten to fifteen years, you would have noticed an increase in the availability of visual alarm devices such as base and wall beacons.
The reason for this increase was due to the higher current available on a wired addressable system and lower beacon current load.
However, for wireless systems to keep up with their wired counterpart any increase in the power demand for such devices is a challenge due to the limited power available from the fixed battery in each wireless device.
As of 2010, there was no Visual Alarm code, and therefore, the beacons produced did not conform to any standard and usually the light emitted from a device was not very bright, you would have to be looking directly at the beacon at the time of the alarm to realized it was flashing.
However, as of 2010, a new standard was introduced called EN54-23 and to comply with this fire standard a much higher lighting output was required, which was 0.4 lux.
The increase in the light output proved to be a challenge to all those designing fire alarm visual equipment, but the challenge was far greater for those designing wireless.
So when talking about the challenge facing wireless designers, how do you achieve much more light from the same power source and still ensure your batteries last the three years as required by the wireless coded EN54-25?
Well, Hyfire has managed to achieve this with their new audio-visual alarm the HFC-SBR-23-03, and It would appear the secret is in the advanced LED technology.
As you can see from the video the light emitted from the VAD is quite impressive. Furthermore, the batteries within the device are the same size as before and the duration of three years has also been achieved.
