WATER
FLOW SWITCH
The water
flow switch can be employed at each nozzle of an extinguishment
systemto verify that water actually sprayed on a detection
of a spark or ember. If water failed to flow on detection
of a spark, a trouble condition will be initiated. The water
flow switch can also be used during system testing to verify
the flow of water when the spray is activated.
HEAT
DETECTOR
A heat
detector is available to monitor for excessive heat in ducts
or in the dust collector. The heat detector provides a contact
closure when the temperature exceeds the detectors rating.
The system may be programmed to spray water or to active
an auxiliary fire suppression system on detection of excessive
heat. This may be utilized to dump water or steam into the
dust collector or activate a preaction sprinkler system.
