The person inspecting and maintaining the hose system shall keep records of inspection and maintenance operations for at least five years after the inspection and maintenance.

According to EVS-EN 12845

The sprinkler system is one of the most common automatic fire extinguishing systems in the world. Automatic means that the system must activate without human intervention, which is why system maintenance and operation is a big responsibility.

The sprinkler system consists of an extinguishing water supply, a booster set, sprinkler system piping and sprinkler heads. The purpose of an activated system is to locate and extinguish fire and to transmit an alarm.

For the sprinkler system to activate, all switches and actuators must be in working order, maintained and inspected, and signals must be allowed to move within the prescribed time to open the shut-off valves, actuate booster pumps, transmit alarms and the water to reach the fire zone. In addition to sensors, switches, valves, manometers, the automatic activation of the pumps must be tested monthly and the efficiency of the booster pumps must be tested at least once a year, as the capacity of the pumps may decrease over time.

During the maintenance of the sprinkler system, the system as a whole shall be analysed and inspected, tests shall be carried out and, if necessary, repairs shall be carried out on the system or parts thereof to ensure that the system activates automatically.
