S-Quad: Put an End to False Alarms
 Gent
has raised the standard within the UK fire industry with its
S-Quad fire sensor range for Vigilon. The
S-Quad from Gent is the UK’s most innovative solution to the
detection and signalling of fires. It uses patented dual angle
optical scatter smoke detection to improve both the speed and
integrity of fire detection. This combined with heat and CO
sensors can help determine whether it is a genuine fire or a false
alarm. This advanced sensing technology is coupled
with an integral sounder with speech capability and strobe in the
same small, intelligent device, making S-Quad a truly unique fire
detection and alarm sensor. For a more comprehensive list please

This guide is aimed at providing advice on the most suitable type of
sensor for specific applications. Obviously conditions may vary
depending on the particular application and if there are any doubts,
please contact us for further consultation. Fire
Sensor System Design- System Category & Selection
Gent by Honeywell will provide FREE advice on
Fire Detection and Alarm system design recognising the
responsibilities imposed on the Designer. The
general steps for the Designer are:
-
Ensure the Fire Risk assessment is complete
-
Confirm level of protection or system
category is correct (listed below)
-
Confirm the 'Cause & Effect'
-
Agree any 'Variations' with all relevant
parties
-
Complete the specification drawings
-
Sign off the G1 Design Certificate required
within BS5839-1:2002
System Categories are fully described within
BS5839-1:2002 and vary depending on the Risk. These are commonly
referred to as Category M, L5, L4, L3, L2 or L1 or Life protection
of P1 or P2 for Property protection. Below is a
small portion of advice taken from notes associated with one of the
Approved CPD training seminars that relate specifically to fire
detection design. Siting of Fire Sensors
Selection and siting of sensors (for further
advice please refer to clauses 21 & 22 of BS 5839-1:2002)
The objective is to select the correct sensor for the appropriate
application, to provide the earliest warning of fire without the
risk of a false alarm. It is therefore worth trying to visualise the
type of fire that is likely to occur in a particular room or area
and also to familiarise oneself with the application and the risks
that could give rise to a false alarm.
It should also be remembered that a Vigilon
system can incorporate a whole range of different sensors using
S-Quad multi-sensors. These can be set up for different applications
and can be switched from ‘state to state’ should particular risks be
present for short periods of time.
This should be read in conjunction with the
application/risk charts, please visit www.gent.co.uk for the S-Quad
Selector, which is available to download.
Obviously conditions may vary depending on the
particular application and if there are any doubts, please contact
Gent for further consultation.
