Loop Beacon Devices
The
visual indication of alarm is a recognised solution
to supplement audible alarms in areas where
high ambient noises are present.
In
some cases visual alarms are used as the only
indication of alarm, for example in hospital
operating theatres or television studios.
Consideration
of fire alarm warnings for people with impaired
hearing is now commonplace in the UK, in particular
as a result of the Disability Discrimination
Act (DDA).
Clauses
17 and 18 of BS5839 part 1:2002 give recommendations
regarding the use of visual alarm signals on
fire detection and fire alarm systems installed
in the UK.
Both
Apollo and Hochiki produce low current visual
alarm indication devices (Loop Beacons). These
devices are connected to the detection loop
circuit and derive their power source and control
data from the control panel.
Loop beacons may be installed on to a base sounder
to provide an audio-visual indication of alarm.
Using
LED technology, these Loop Beacons are designed
to emulate the flash pattern of the traditional
Xenon beacons, but at a fraction of the current
consumption.
The
current range of Kentec Syncro and Solo 2 control
panels fully support Loop Beacon devices. However,
as these are alarm devices, consideration should
be given to the loop current drawn by these
units when operated.
The
maximum number of loop beacons that may be fitted
to each control panel loop is given in the following
table. To download pdf 
Compatibility note:
Hochiki protocol panels (Syncro and Solo 2)
need to be fitted with V4 firmware in order
to support the Hochiki loop beacon.
Solo 1 and Signifire control panels are not
compatible with the Hochiki loop sounder.
Apollo
loop beacons have the same type designation
as a loop sounder and are therefore supported
on all panels that support loop sounders.
