General Comments
Personnel required to work in the protected area should be
conversant with the detection and extinguishing equipment
installed, and trained in fire procedures�� All life-saving
equipment must be properly maintained��
The method of system operation is chosen at the
design stage to suit the protection required for the hazard
area and the environmental factors appropriate to that
area�� This part of the document provides information
relevant to ALL the standard operational systems to cover
the eventuality of changes to, or expansion of the original
design��
System Detection and Actuation
General
Each system is designed to suit the hazard area, whether
the area is normally manned or unmanned, and whether
the detection/actuation devices are to be manual or
automatic�� The permutation of systems is large but from
an operational point of view, the systems are best grouped
as:-
• Manual��
• Fully Automatic��
• Automatic with Manual Intervention��
Manual System
Manual systems depend on human detection of a fire in
the hazard area and prompt action to actuate the manual
actuator for the FM-200
®
system to discharge and flood
the protected area and extinguish the fire��
All other instructions associated with manual
operation form part of the user’s procedures on safety
precautions and fire drill�� If required assistance can be
provided to help the user prepare procedures for safety
and fire precautions��
Fully Automatic System
Where a sensitive fire detection system is included for the
automatic release of extinguishing agent, the system shall
only be capable of automatic release once two or more
sensors detect the fire��
The number of detectors and their spacing is designed
to ensure a satisfactory response time�� To ensure personnel
may safely evacuate the risk area an adjustable time delay
should be fitted such that sufficient time may elapse prior
to system discharge�� Ideally, the delay period shall not
exceed 30 seconds (BS5306-5)��
Prior to system discharge (and at the commencement
of any time delay period) a clearly audible alarm different
from any other used shall sound and continue until the
complete system is reset�� In areas of high ambient noise
level, a visual indication may also be required, in addition
to the audible warning��
The design of a system for automatic detection, signal
distribution, alarms, etc�� is not always of our supply��
Therefore, details appertaining to fire detection and
alarm operation and maintenance are not included in this
document��
UL Listed Detection & Control Equipment
Detectors shall be UL Listed for the intended application��
Control Panels shall be UL Listed for releasing device
service and compatible with detection and FM-200
