Comments

Bedrooms (Hotel, Hospital incl
Wards) |
OPTICAL
|
A Smouldering Fire is more likely
to exist due to bedding and furniture.
NB: However, if smoking is permitted
in Hotel Rooms then Ionisation detectors would be less
prone to unwanted alarms. Care must be taken in respect
of the location of the detector.
|
Cargo Handling Area |
OPTICAL
|
The presence of dust and air
currents could present problems with Ionisation. Beam
Smoke Detectors should be considered for large, open and/or
high areas. |
Churches (Chapels) |
BOTH
|
Both types are suitable. Consideration
must be given on the contents within the building, ie:
smouldering fires = optical
Flame Fire = Ionisation.
|
Corridors/Passages |
OPTICAL
PREFERRED
IONISATION
ACCEPTABLE
|
As air currents exist in these
areas, and of a building, optical are preferred to detect
visible smoke. |
Data Processing Areas
incl: Telephone Exchanges |
BOTH
|
A smouldering Fire is more likely
to occur due to many cables with PVC covering. However,
consideration must be given to all room contents in respect
of which type of fire is more likely to occur and the
possible use of high sensitivity sampling systems for
rapid response. |
Conference Rooms |
BOTH
|
In general, Smoke Detection
should be utilised but consideration should be given to
the proposed use of the room and the possibility of smoke
build up when in use. Rate of Rise Heat Detectors may
be considered in place of Smoke Detectors - take note
of the different spacing requirements. |
