The HD-MS671 end water testing device consists of a large space detector HF-JZ661 power interface box DC652, solenoid valve, pressure gauge, water supply pipe fittings, etc. It is used to measure the status of the fire compartment electrical control system and the water pressure and flow values at the most unfavorable point of the compartment. According to different flow rates of water cannons, corresponding simulated flow plates need to be configured. When in use, the signal is detected by a large space detector, linked to an electromagnetic valve, and an alarm and pump start signal are issued.
