9.23RESET

9.23.1RESET OF ADDRESSABLE DETECTOR

For about 20 seconds after reset is applied to an addressable detector, the exponential filter and slope limiting filter are disabled if their input values are less than their output values. In other words their outputs will follow their inputs downwards with no filtering. However increases in input values will be filtered as usual.

If the LED is latched on due to a previous alarm it will be turned off.

The state of any AVF applied to the detector is reset to the “no-alarm” quiescent state.

RESET has no effect on 814PH detectors operating in “FastLogic” mode.

9.23.2RESET OF DIM MODULE

Power is removed from the attached conventional detectors for about 5 seconds. Then power is re-applied, and sampling resumes 5 seconds later.

If the DIM module LED is latched on due to a previous alarm it will be turned off.

The state of any AVF applied to the detector is reset to the “no-alarm” quiescent state.

9.23.3RESET OF ANCILLARY INPUT DEVICE

If the LED is latched on due to a previous alarm it will be turned off.

The state of any AVF applied to the detector is reset to the “no-alarm” quiescent state.

9.23.4RESET OF ANCILLARY OUTPUT DEVICE

No action.
