State 0
(LPC
approved)
(Default) Grade 2, rate of rise and
fixed temperature
Suitable for general use in ambient temperatures up
to 40
o
C. Provides detection to Grade 2 performance
as defined in BS5445 : Part 5.
State 1
(LPC
approved)
Grade 1, faster rate of temperature
rise as well as fixed temperature
Applicable for areas with normally very steady low
ambient temperatures. A faster rate of rise can
signal a fire below the normal set temperature at
58
o
C.
State 2
Grade 1, limited rate of rise
Applicable for normal ambient temperature where
temperature variations are expected up to 40
o
C but
faster response than grade 2 is required e.g. hotel
bedroom.
State 5
High temperature
with
rate of rise
Provides detection as specified by
Range 1
BS5445:Part 8 .
State 6
High temperature
with no
rate of
rise
Provides detection as specified by
Range 1
BS5445:Part 8
.
State 15
No detection
No detection. This is a total disablement of the
sensor.

Default detection
A
fire
is detected when there is a 50% (3dB) fall in signal level,
however if the fall is by 90% (10dB) in less than 1second and is
maintained for 40 seconds, then a
fault
is registered. This allows
the Control panel to differentiate between a fire and a fault signal
caused by accidental obscuration.
State 1
Normal sensitivity
A
fire
is detected when there is a 50% (3dB) fall in signal level,
however if the fall is by 90% (10dB) in less than 1 second and is
maintained for 40 seconds then a
fire
is registered.
State 2
(LPC
approved)
Medium Sensitivity
A
fire
is detected when there is a 25% (1.3dB) fall in signal level,
however if the fall is by 90% (10dB) in less than 1 second and is
maintained for 40 seconds then a
fault
is registered.
State 3
Medium Sensitivity
A
fire
is detected when there is a 25% (1.3dB) fall in signal level,
however if the fall is by 90% (10dB) in less than 1 second and is
maintained for 40 seconds then a
fire
is registered.
State 4
High Sensitivity
A
fire
is detected when there is a 10% (0.5dB) fall in signal level,
however if the fall is by 90% (10dB) in less than 1 second and is
maintained for 40 seconds then a
fault
is registered.
State 5
High Sensitivity
A
fire
is detected when there is a 10% (0.5dB) fall in signal level,
however if the fall is by 90% (10dB) in less than 1 second and is
maintained for 40 seconds then a
fire
is also registered.
State 15
No detection.
This is a total disablement of the sensor.
