User Controls
The Prescient panel has clear, unambiguous
fire and extinguishing system status LED
indications.
Fire status LED
indications.
Extinguishing
system LED
indications.
These single-function
user controls are easy
to operate.

enable user
controls
Status Indicators
Two types of status indicators are available in small, matching
enclosures.
 status indicator with auto/manual keyswitch
 status indicators with manual release and auto/manual keyswitch,
abort and timer hold
Weatherproof status
indicators are also available
(not illustrated).
LC250 Weight Monitor
The LC250 Weight Monitor is
designed to detect and
indicate leakage from
extinguishant cylinders.
Easy to configure controller
links up to 4 weigh monitors
and may be linked to
extinguishant control panel
to provide fault indication in
the event of extinguishant
leakage.
No need for mechanical
assemblies which take up
space.
Solid state electronic weight
monitors with no moving
parts ensure simple
installation with reliable
performance.
