Relays
«Fire» and «Failure» have NC and NO contact groups. The company produces
detectors with the following relay configuration:
«Fire» relay – normally open (always open when power off, closed when power on and
fire detected)
«Failure» relay – normally open (always open when power off, closed when power on
and instrument availability)
On request, manufacturing of the detectors with normally closed contact relay
groups is possible.
«Fire» relay – normally closed (always closed when power off, open when power
on and fire detected)
«Failure» relay – normally closed (always closed when power off, open when
power on and instrument availability)
