Notification/Fire Watch - Unplanned Outage

When does the fire watch start and end for an impairment of a fire safety system?

If there is an impairment of a fire alarm or sprinkler system (see EC.02.03.05 for related systems), the clock starts at the time of the impairment. If the system is restored within the four hours for fire alarm systems or 10 hours (cumulative) for fire sprinkler systems, the clock stops. The time-frame noted for each system is a cumulative period of time over 24 hours rather than an individual occurrence.
