1. Check whether the test device at the end of the sprinkler pipe network is normal (whether the water pressure and flow meet the requirements).
2. Check whether the test water flow indicator is sensitive, whether the alarm is accurate, whether the reset is normal, whether there is a display in the fire center.
3. Check whether the sprinkler and pipeline are in good condition, and whether there is any hidden danger.
4. Check whether each valve is in the normal open state, test whether the floor signal valve switch is flexible, and whether the fire center has a closing signal display.
5. Check and maintain the water pump adapter of the sprinkler system to make sure integrity and no leakage.
6. Test regularly whether the safety pressure relief valve is sensitive and reliable, and check whether the water hammer absorber works effectively.
7. Check if the automatic exhaust valve of the spray riser works normally.
8. Check and test whether the wet system alarm valve and hydraulic alarm bell are in good condition, whether the spray pump is started, and whether the display of the fire center is accurate.
9. Check whether the valve is flexible and effective regularly. If the valve is not closed tightly or can’t be used flexibly, it should be repaired in time. If the contact surface of the valve is defective, it needs to be ground and replaced if it can’t be repaired. Add oil regularly to the bolts of the rotating parts of the valve.
10. Check whether the turning on and off of the check valve is flexible and effective.
11. Check the fire sprinkler system pipe network regularly, replace severely corroded pipes, and for pipelines with peeling paint, remove the rust, and paint the anti-rust paint and marking paint.
