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
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
