Application in / Suitable for:
Clean area or environment, where early detection
is required
General area as STATE 0 with less immunity to
steam and dust for ease of testing using artificial
smoke in normal operating mode, when test /
commissioning mode is not active
General area
General application in area with transient steam,
dust or smoke present
General application in area with low dust, smoke
or steam present, for fixed temperature operation
that is totally unaffected by transient temperature
variation
Area having high ambient temperature with low
dust, smoke or steam present
Areas with moderate dust, smoke or heat during
working hours when used with timing function
Area having high ambient temperature, plus
where moderate dust, smoke or steam present
Area having high ambient temperature that
changes, plus moderate dust, smoke or steam
present
Area where smoke, dust or steam occurs at times
Application in / Suitable for:
Clean area or environment where early detection
is required with false alarm reduction
General area as STATE 0 with less immunity to
steam and dust for ease of testing using artificial
smoke in normal operating mode, when test /
commissioning mode is not active
General area where false alarm reduction is
required for comprehensive fire detection
General area with moderate dust, smoke
(tobacco) or steam, operates at a fixed
temperature and is totally unaffected by transient
temperature variation
Applications with moderate dust, smoke
(tobacco) or steam
Area where high levels of smoke, dust or steam
is often present
Area with high ambient temperature, plus low
levels of dust, smoke or steam present
Area where smoke, dust, steam or gas occurs at
times
