release
• Double interlocked preaction with electric / pneumatic
release
1.7 RELEASING
1.7.1 Electric releasing conditions
The electric releasing condition is needed by an approved
releasing control panel in order to operate the electric
actuator (C) of the NOVEC 1230 and the solenoid
valve (F1) of the preaction system. It can be achieved as
the following:
a) Single zone detection activated by either Zone 1 or
Zone 2.
b) Cross zone detection activated by both Zone 1 and
Zone 2.
c) Manual pull station activated.
1.7.2 NOVEC 1230 electric release
Electric release is achieved with an electric actuator (C)
installed on the discharge valve (B) of the cylinder (A).
When the releasing conditions are fulfilled, a 24Vdc source
is applied to the electric actuator (C) thereby venting the
pressure on top of the discharge valve (B) thus allowing
the extinguishing agent NOVEC 1230 to be discharged
through the piping and nozzles.
1.7.3 Double interlocked preaction electric release
Release trim for the double interlocked preaction system
with electric / pneumatic release utilizes a normally closed
solenoid valve (F1) controlled by control panel listed for
releasing with a compatible detection system, and a
pneumatic actuator (F3) normally held closed by
supervisory air pressure maintained in the sprinkler piping.
In fire condition, when the detection condition is fulfilled,
the control panel energizes the solenoid valve (F1) and an
open sprinkler releases the supervisory air pressure from
the sprinkler piping. Both the electric detection condition
and supervisory pressure relieved from the sprinkler piping
are necessary before the deluge valve (A1) will open and
fill the sprinkler piping with water. Water will flow from any
opened sprinklers in the system piping.
