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 and provide unrivaled value for money
by offering a highly featured panel at a lower
market price.
Each panel in this series has extensive
configuration options but remains “simple to
install, program and operate” as reported by
satisfied installation engineers and critical end-
users.
A comprehensive range of technically detailed,
support documentation relating to commission-
ing, operating, maintenance and fault finding is
easily available if required. In addition, a
complete range of compatible accessories is
available to support the series and satisfy most
customer requirements.
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 systems. 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.
The panel provides 0.5 A output at 28V DC to
operate interior/ exterior status indicator units.
Outputs for auto, manual and discharge are
provided at 250mA each.
Eight normally - open inputs provide for remote
evacuate, silence alarms, systems reset, lock-off
input, low pressure input, gas discharged
pressure switch input, remote abort and remote
fault. Clean contact relays are provided for first
stage signalling, second stage signalling, system
reset, common fire, common fault and system
discharged.
Please note that in contrast to the T530, the stand
alone “abort” button feature is not compatible
with this panel.
Top-entry plastic grommets, bottom-rear entry
plastic grommets (for mains) and rear entry
knock-outs are designed to assist with cable
termination.
Panels are boxed complete with three-sticker sets
allowing user selection and application on site.
