Wet Alarm Valve System and Equipments

Wet Alarm Valve System and Equipment are designed for heated volumes and use cases where there is no risk of water falling behind 4°C and freezing. Alarm check valves and flow meter detectors are used for mechanical and electronical alarming

Application Areas

-Warehouses
-Factories and Workshops
-Hospitals
-Malls
-Skyscrapers and Residences

Wet Alarm Valve Body

Dimensions: 3”-8”
Connection: Flanşlı x Flanşlı
Flanşlı x Yivli
Yivli x Yivli
Assembly: Dikey
Working pressure: 250psi
Approvals: FM, UL

Retarding Chamber

Retarding chambers are used in automatic wet type sprinkler systems to prevent false alarms and panic that can be caused by that

Material: Paslanma Çelik
Connection: ¾”Bsp
Working Pressure: 300psi
Approvals: FM, UL

Water Motor Gong

Water motor gongs are fire alarm bells that don’t need electricity to operate. Instead, they’re physically triggered by water flowing through a fire protection system—making it easy to meet fire code requirements to sound a continuous alarm, even if electrical power is lost. They can be mounted on the wall or the alarm valve, regarding to their type.

Strainer is used in the line that connects to alarm valve or retarding chamber. Then water motor gong is assembled.

Material: Corrosion resistant aluminum blend
Water input: ¾”Bsp
Drainage: 1”Bsp
Working Pressure: 300psi
Approvals: FM, UL

Pressure Switch

Pressure switches are used to detect fluctuations on pressure in sprinkler systems. There is water and air pressure type switches and can be used indoors and outdoors. Pressure set range is between 4-20psi.

The factory setting is between 4-8psi.

Working Temperature: -40 °C ~ +71°C
Connection: ½” Npt
Working Pressure: 300psi
Approvals: FM, UL

Wet Pipe Sprinkler Systems Principle Schema

When sprinkler (1) activated and water start flowing (2) flap of alarm valve lifts and water flows to alarm trim set,(3) then arrives to retarding chamber. (4) Retarding chamber fills with water in a matter of seconds, then pressure switch (6) activates electrical alarm followed by water motor gong’s (5) mechanical alarm.
