Fire alarm with distinct alarm reset threshold |
摘要 |
A hazard alarm includes: a detector for detecting a hazard parameter; trigger logic; and reset logic. The trigger logic triggers an alarm state when the measured parameter reaches a predetermined trigger threshold. The alarm state is maintained until a reset is successfully performed. The reset logic, upon a reset command, resets the alarm state if the measured parameter is below a predetermined reset threshold, and inhibits resetting of the alarm state if the measured parameter is above the predetermined reset threshold.
