Product Overview:
The FM/UL Certified Alarm Check Valve is a critical fire sprinkler system component designed to prevent backflow while triggering waterflow alarms during activation. Available in flange and grooved end configurations, this heavy-duty valve meets FM Global (FM) and Underwriters Laboratories (UL) standards, ensuring compliance with NFPA 13, 14, and 72 for commercial and industrial fire protection.


Alarm Check Valves act as a water flowalarm initiating device in wet pipe sprinkler systems. When waterflows in the sprinkler system due to the operation of one or more automatic fire sprinklers, the alarm valve opens allowing continuous flow of water into the system, which will activate water motor bell and pressure switches.
The design of the Alarm Check Valve alows for installation under both variable and constant supply pressure conditions. The valve trim incorporates a bypass between the water supply and the wet pipe system. When pressure surges in the waters supply occur, the trim allows a small amount of water to bypass the clapper limiting the potential of false alarms.
 

Application

1. Wet pipe fire sprinkler systems
2. Industrial fire protection networks
3. High-rise building standpipes
4. Water storage tank supply lines

This system is applicable to the places with the ambient temperature from 4°C to 70°C. This system is generally installed in the places with fire hazards, like the hotel, shopping mall, hospital, theater, office building, conference center, warehouse,high-rise building and underground garage.
 

Installation Note

This instrument shall be installed in places where is easy to observe and access.Install The wet alarm valve vertically on the pipes which have been properly tested for its pressure and cleaned. Please note that the arrow for water flow direction is pointing upwards. Reserve enough operation space for repair and maintenance before installation.
Step1: Clean the system pipe network completely before installation. Ensure that the inner wall of the pipes is coated with rust-proof layer and there is no dreg or dirt in the pipes.
Step2: In order to facilitate the observation of the pipe in which an alarm occurs, it is recommended to discharge the water from an open port or have the water discharge state easy to be observed before installation.
Step3: Check whether there is any damage at the joint between the wet alarm valve and the flange, check whether the seal is in good condition and whether the valve disc moves flexibly, carry out the leakage test with a pressure of two times of the rated working pressure.After the test, the valve disc shall be free of leakage;If there is any problem, replace the spare parts or clear the trouble before assembling the parts together.
