DUAL unit provided without integrated releasing
control panel is factory wired for the following configurations:
7.1.1 NOVEC 1230 electric release
Electric release is achieved with an electric actuator (C)
installed on the cylinder valve (B) of the cylinder (A). When
the conditions of release are fulfilled, a 24Vdc source is
applied to the electric actuator (C), which will vent the pressure
on top of the cylinder valve (B) allowing the extinguishing
agent NOVEC 1230 to be discharged through the nozzles.
7.1.2 Double interlocked preaction electric release
Release trim for the double interlocked preaction system
utilizes a normally closed solenoid valve (F1) connected to
an approved release control panel.
When the conditions of release are fulfilled, a 24Vdc
source is applied to the solenoid valve (F1). Upon the
opening of a sprinkler, the pneumatic actuator (F3) will
release, allowing the opening of the deluge valve (A1).
The water will enter the sprinklers network and water will
flow through opened sprinkler heads.
