| WET ALARM VALVE BODY |
Grooved x Grooved Grooved x Flanged Flanged x Flanged |
200psi-300psi | – | 3”-8” | Mechanical and electronical alarm for use with check valves or water flow detectors. |
| RETARD CHAMBER | – | 200psi-300psi | – | ¾”Bsp | It is used in conjunction with wet pipe sprinkler systems . It serves primarily as a hydraulic time delay to prevent most false alarms associated with fluctuating water supply pressures. |
| WATER MOTOR GONG | – | 200psi-300psi | – | ¾”Bsp | Hydraulically operated indoor/outdoor alarm for use with fire protection systems. Can be used in conjunction with alarm check, dry pipe, deluge, and preaction valves to sound a local high decibel alarm. |
| PRESSURE SWITCH | – | 200psi-300psi | -40 °C ~ +71°C | ½” Npt | It can be used in conjunction with alarm check, dry pipe, deluge, and preaction valves to detect pressure shift and sounds an alarm. |
- Wet Pipe Sprinkler Systems are designed for heated buildings and areas susceptible to freezing( i.e. temperatures are about +4°C ).
- If the sprinkler opens, the water flow opens the alarm valve disc and reaches the raetard chamber via alarm valve body. The retard chamber fills in seconds, first the pressure switch sounds the electrical alarm, after the water in the water motor gong sounds the mechanic alarm. UL LIST-FM certified.
