Model 501 Remote Actuator will trip a CALIFORNIA
Valve when a 24-VAC or 24-VDC signal is present.
Applications include panic switches, fire
or sprinkler alarms, fire-suppression systems, and gas sensors.
Signals from those systems can trip relays to supply the necessary
power to activate the Model 501.
The power draw on Model 501 is 15 Watts. The
source of power is usually a 24-V backup, on-line power supply.
Model 501 is an optional feature that is mounted
on the seismic valve by the factory at the time of manufacture.
Valve with a factory-mounted
Model 501 will trip during a violent earthquake or when an
electrical signal is present.
Model 501 Remote Actuator consists of a cast-iron
shell with a potted solenoid inside. When the solenoid coil
is energized, magnetic forces are produced that attract the
ball in the trigger mechanism of the seismic valve, which
trips the latch mechanism and causes the seismic valve to
