Low sensitivity optical smoke sensing is not approved but may still be useful in certain applications.
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
The STATE 15 is no detection and is not part of LPCB approval.
Application in / Suitable for:
Clean area or environment where early detection is
required with false alarm reduction.
