CO Sensor Service Life
The service life of the CO sensor is limited. The FAP-440-TC detector switches the CO sensor
off after 6 years of operation and indicates a trouble (LED flashing yellow). On the fire panel,
the detector in question is displayed with a corresponding trouble message. It will continue to
function similar to a photo/heat detector FAP-440-T. The detector should then be replaced
immediately in order to maintain the superior false alarm immunity of the photo/heat/CO
detector.

Mounting
–
Follow NFPA-72 guidelines for mounting locations. For commercial and industrial
installations, 30 ft. (9 m) spacing between smoke detectors is recommended.
–
The electrical boxes must be sized to accommodate the number of conductors as
specified by the National Electrical Code or the local Authorities Having Jurisdiction
(AHJ).
NOTICE!
The isolator bases have their own LEDs which will signal a trouble condition in the case of a
short circuit.
NOTICE!
Multisensor detectors with CO sensors must be replaced every 6 years.
NOTICE!
Smoke detectors are not to be used with detector guards unless the combination has been
evaluated and found suitable for that purpose.
