In Chapter 3 of the LSC, a fire clock is defined as the distribution of one or more persons with the following functions:
Notifying firefighters, building occupants, or both of them in an emergency
Preventing fire from happening
Small fire extinguishers
To protect the public from fire or safety hazards
Emergency damage may include interruptions to the water supply to the system, frozen or burst pipes, equipment failures, and any other damage identified during system inspections. The Code also covers pre-programmed damage that occurs when the system has to be shut down for a period of time to allow for open fire operations such as welding in areas with automatic fire detection systems or disconnection of the system for inspection and maintenance purposes.
In sprays and other water-based fire protection systems, NFPA 72 defines corruption as “an abnormal state” that causes your system or part or its function to malfunction. Damage to any of the following types of equipment or parts of your system may result in the need for a fire alarm:
Spray systems, including water spray, water mist, and foam water systems
Fire pumps and fire pipe systems
Water storage tanks and underground fire hydrant pipes
Disruption of water supply
According to the NFPA, for fire alarm systems, you must use a fire alarm if the system is disabled for more than four hours in a 24-hour period. For spraying or water-based systems, a fire clock service is required to turn off that lasts more than 10 hours in a 24-hour period. In any case, the first thing you need to do is inform your local department about the situation.
General requirements for fire clock services will vary from place to place based on local and regional laws and regulations. There are usually a lot of regulatory authorities, some of which may be more complex than the NFPA, and some may be less. In any case, strict rules apply and are a priority so you should understand the rules that govern your specific circumstances.
Fire Watch Guards are dispatched to buildings with broken or malfunctioning fire alarms or spray systems when they have a list of tasks that include keeping a watch on the building and surrounding areas, which act as human firefighters.
Firefighters should report a fire, smoke, or any other danger immediately and alert everyone in the building along with other Fire Watch Services. They are also tasked with keeping a fire history record of all actions taken during the viewing.
All property owners and managers must have a robust plan and plan for situations where firefighters are needed.
