3- System with Pneumatic Release
1. Description
The T
OTALPAC2 System with the Viking Deluge Trim utilizes
a Viking Deluge valve (A1) to control water flow into system
piping equipped with open sprinklers and/or spray nozzles.
The system piping remains empty until the Deluge Valve is
activated by operation of the release system.
Pneumatically controlled deluge systems require a pneumatic
release system, equipped with fixed temperature releases
and/or pilot heads. Release trim, for pneumatically controlled
deluge systems utilize a Pneumatic Actuator (F3) normally
held closed by pressure maintained in the pneumatic release
system.
Deluge systems are designed so the Deluge valve will
open when a detector on the pneumatic release system
operates. When the Deluge Valve opens, water will flow
into the sprinkler piping and out of sprinklers and any
opening on the system.
Note: The air supply for the pneumatic release piping
system must be provided by the contractor and installed
outside the TOTALPAC2 cabinet. The air supply must be
restricted to ensure that the automatic air supply cannot
replace air as fast as it escapes when a releasing device
operates. It is also recommended to provide Inspectors
Test Connections on both the release system and the
sprinkler system.
Deluge T
OTALPAC2 Systems are commonly used where it is
desirable to simultaneously spray water from all open
sprinklers and/or spray nozzles on the system when the
system operates.
