Fire Protection System (FPS), a System Sensor dealer in Bhopal, supplies System Sensor sprinkler monitoring devices: WFD waterflow detectors for 2 to 8 inch steel pipe, the WFDT vane-type waterflow detector, and the PIB-V2 and OSY2 supervisory switches that watch sprinkler control valves. FPS installs, tests and maintains them across Madhya Pradesh.
A supervisory switch that monitors the open position of post indicator and butterfly control valves, with a bi-directional actuator for rising or falling flag installations.
A supervisory switch that monitors the open position of outside screw and yoke (OS&Y) gate valves, for indoor and outdoor use.
Waterflow detectors for steel sprinkler pipe, with one model for each pipe size from 2 to 8 inch. They signal the panel when water flows and use a mechanical retard to reduce false alarms.
A vane-type waterflow detector that fits any tee with a 1 inch NPT branch, for small sprinkler lines in steel, brass, copper, CPVC or polybutylene.
Sprinkler monitoring devices tell the fire alarm panel what the sprinkler system is doing. A waterflow detector signals when water starts to flow in the pipe, which normally means a sprinkler head has opened. A supervisory switch watches a control valve and signals if the valve is moved away from its open position, so a closed valve does not go unnoticed.
For waterflow on steel pipe, choose the WFD model that matches the pipe size: WFD20 for 2 inch, WFD25 for 2½ inch, WFD30-2 for 3 inch, WFD40 for 4 inch, WFD50 for 5 inch, WFD60 for 6 inch and WFD80 for 8 inch. They suit schedule 10 through 40 steel pipe, mount vertically or horizontally, and have a mechanical retard that reduces false alarms from pressure surges or trapped air. For small branch lines, the WFDT vane-type detector fits any tee with a 1 inch NPT branch, including threaded ferrous and brass tees, copper sweat tees, named brands of 1 inch CPVC tees and 1½ inch polybutylene tees.
For valve supervision, match the switch to the valve. The PIB-V2 suits post indicator, butterfly, wall post, recessed wall post and pressure reducing valves, and its bi-directional actuator works with rising or falling flag installations. The OSY2 is made for outside screw and yoke (OS&Y) gate valves from 1 to 12 inch, with an adjustable shaft and a wide bracket span for awkward valves.
FPS supplies, installs and maintains System Sensor sprinkler monitoring devices in Bhopal and across Madhya Pradesh.
