Application
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.
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.
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.
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.
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.
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.
This is a total disablement of the sensor.
