stylised to be compatible with all leading brands of
conventional smoke detectors.
As I have previously mentioned visual alerts aid
with DDA compliancy which is an important factor
to why beacons are also an essential fire alert form
but this then highlights how will the visually
impaired know of a problem? This is why sounder
beacons have proved themselves to be an ever
growing, huge success; due to its combination the
product alerts both the visually and the audibly
impaired, ensuring that no-one is left at risk.
Sounder beacons are typically available with a
range of various lens colour options, and the
sounder quality and output should be equal to
that of standard sounder.
Standard sounders are the most common to
any facility. Most come with a vast number of
different tones for the end user to select from and
typically run of 12 or 24 Volts, but are also obtain-
able to run off mains voltage. A recommendable
sounder is one that can be quickly installed, locked
into place, features a switch to select volume
output and tone selection and has the ability to be
over-ridden by a second stage alarm.
With the function of a sounder being to alert
people to a problem, in essence saving lives, it is
essential to ensure that all fire safety equipment is
installed correctly; Design, Installation, Commis-
sioning, Verification, Acceptance, Alteration and
Test are all the certificates fire alarm installation
requires.
Regulations specify that a minimum of 65dB is
given out by any sounder in a general area with an
addition of an extra 5dB above any further back-
ground noise. In a facility where people will be
sleeping a sounder is required within each allocated
sleeping room, situated at the bed head, sounding
