Description
In some applications, the system discharge must be
delayed for a short time following actuation. This is usually
in areas where it is necessary to evacuate personnel prior
to discharge. A manual release is incorporated on the time
delay valve to allow instant override of the time delay. The
length of delay is factory set and is not adjustable.
The time delay assembly uses INERGEN
® pressure to
power the factory-set delay mechanism. Install the assem-
bly in the discharge piping, either directly after the control
(pilot) cylinder or further along the piping. The assembly is
reversible to accommodate right and left hand configura-
tions and will operate in any mounting orientation. After the
discharge is complete, pressure in the assembly slowly
returns to normal and closes the time delay valve.
