The 614CH fire detector provides very early warning
of slow smouldering fires. The CO fire detector
is well suited to many applications where heat
detection is insufficient but smoke detection causes
unwanted alarms. As CO travels more freely than
smoke, the positioning of CO fire detectors is more
flexible. This feature is particularly useful in large
complex structures such as atria and warehouses,
where positioning of smoke detectors is difficult.
The 614CH has an additional mode of operation as
a Class A1R combined rate-of-rise and 60°C fixed
temperature heat detector to supplement the CO
detector mode to permit the detector to react to
a wider range of fire types. Although the 614CH
has an expected life in excess of 10 years, in order
for the 614CH to provide the intended level of
fire detection, the detector should be checked for
calibration 5 years after installation (or 5 years after
re-installation following service) or within 7 years of
the date of manufacture.
