Three strikes but still in
It is a common misconception that lightning never strikes twice in the same
place. Indeed, the Gent Vigilon fire detection and alarm system installed last
year at RAF Lossiemouth on Scotland’s north east coast, has taken three
lightning hits already. Yet none of these caused damage to any of its many fire
panels – a testimony to the system’s robust design.
Because of its location and the number of masts around the base, RAF Lossiemouth
is particularly prone to lightning strikes. Though no fire system can ever offer
total immunity, Vigilon does have a good level of resistance, this largely being
due to the over-voltage protection built into all loop-wired devices and to the
signal isolation technology incorporated in the panels. On each occasion that
the Lossiemouth system was struck, its operation was virtually unaffected,
damage being restricted to a few easily replaceable sensors.
Gent combined multi-sensor/sounders have been fitted in all bedrooms. Each of
these provides both optical (smoke) and heat detection, thus ensuring a high
level of protection. This use of a product that combines alarm and detection
functions helped to speed the installation process, as did the fact that all
system devices are powered from the panel loops, even the sounders, which
avoided the need for separate circuitry. In total, the system incorporates 2563
individual devices, including manual call points and interfaces to ventilation
plant and gas valves.
Owing to the project’s fast-track nature, the time savings made possible by the
Vigilon system’s design were of significant help to Amec Building and Facilities
Services, the company that installed it. And on commissioning, Systems
Integrator Scotshield, benefited considerably from Vigilon’s soft addressing
feature, which enables automatic assignment of device addresses. Also, with
short-circuit isolators on every device, faults can be rapidly pinpointed, thus
reducing commissioning time still further.
RAF Lossiemouth intends that its Gent fire system will eventually be extended
throughout the base to over 100 buildings. In anticipation of this expansion, a
PC-based supervisor will shortly be installed for system management.
Scotshield Fire and Security are an ‘Elite’ systems integrator within the Gent
24 Approved Network.
