Works with all 3/4” to 8” PSP valves. The Model RA501 Remote Actuator will add an additional layer of protection to panic switches, fire and sprinkler alarm systems. A California valve with an RA501 Remote Actuator will trip during a violent earthquake or when an electrical signal is present. A typical customer’s system would include a 24-volt transformer, panic switch and our RA501, providing both panic/emergency shut-off and seismic protection. | |||
