General :
- The Water Motor Alarm is a hydromechanical automatic sound warning device actuated by water flow.
- It sounds a continuous alarm while a deluge or Water Control Valve operates.
- Should be used indoors.
- UL listed.
WEFLO Water Motor and Gong, FIG.WMA-16
Operation :
When a Deluge Valve is activated, water flows through the valve’s trim, discharges to a strainer and into the water motor inlet, From the inlet, the water flows through a nozzle which directs the stream to the impeller. The stream turns the Impeller and drive shaft, causing the striker arm to rotate, thus producing a continuous alarm. The water is discharged thro-ugh a 1″(25mm) drain outlet at the bottom of the impeller ho-using. The discharged water must be piped through the wall to a suitable open drain.
