General
Introduction
The
prescient range of extinguishant panels is a powerful yet
user-friendly series of control panels. They are designed and manufactured
to a high standard.
Each panel in this
series has extensive configuration options but is easy to install,
programme and operate. This is supported by comprehensive documentation on
commissioning, operating, maintenance and fault finding. In addition,
there is a complete range of compatible accessories available to support
the series and to meet most customer requirements.
Technical
Introduction
The
prescient range of extinguishing panels is available in two
variants - either as a gaseous extinguishant panel or a
pre-action water sprinkler panel. Panels are housed in
well-designed enclosures with partially glazed doors. Steel parts are
finished in a hard-wearing epoxy paint.
Three fully-monitored
detection zones are provided. Zones 1 and 2 normally provide first stage
and second stage fire conditions to allow extinguishant discharge
(double-knock zones). Zone 3 is an auxiliary zone for detection only
purposes. Zone 4 is used as a manual release zone.
Two
fully-monitored alarm circuits are provided, each rated at 1A and may have
various configuration options via the engineers' DIL switch settings. Two
fully-monitored actuator/solenoid circuits, each rated at 1A, operate
simultaneously upon "extinguishant release".
The panel can be
operated in either automatic mode or manual mode. In the manual mode, the
detection circuits will continue to operate, giving first stage alarms and
signals to ancillary equipment, but will not automatically actuate the
extinguishing system. This mode can only be overridden by the operation of
a manual release unit. On operation of the manual release, a separate or
different sounder could be activated. In the automatic mode, following a
double knock situation, the release facility will be activated at the end
of the time period.
