Series 600 Conventional Fire Detection

Range Zettler conventional detector
design evolution has resulted in
the creation of the Series 600 range
of unobtrusively styled detectors,
incorporating a number of unique
design features enabling improved
operation, installation and ease of
servicing.

Through innovative design Series 600 detectors have

the ability to reduce installation and servicing time to
a minimum, needing only one visit to the ceiling to
complete the installation and having a park position Features
for the detector to simplify servicing.

Application

As each type of fire detector responds to a particular “fire

product”, the relative speed of response of the detector is
therefore dependent upon the type of fire being detected.
The range of Series 600 fire detectors have been designed
to provide the earliest possible warning of a fire condition,
with a minimum possibility of false/unwanted alarms.

As smoke is normally present at an early stage in most

fires, smoke type detectors (optical, high performance
optical and ion chamber) are therefore considered the
most useful. When considering the type of smoke
detector for the application, the probable type of fuel
for the fire should be considered, in general terms, fast
developing fires are detected quicker with ion-chamber
detectors, whereas with a slow developing fire an optical
type smoke detector will respond quickest. But for
general fire detection, where there is an equal possibility
of either a “fast” or “slow” fire developing the intelligent
high performance optical detector provides an excellent
detection response.In situations where the installation
of smoke detectors would cause an unacceptable level
of false alarms, heat detectors or the enhanced CO fire
detector may be installed.
