General Section - Deluge System
FM-086G-0-15E
6. Configurations Description
A Deluge system is a fixed fire-protection system which
totally floods an area with pressurized water through a
system piping of open nozzles or sprinklers. The system
piping is empty until the Deluge Valve is activated by a
hydraulic, pneumatic, electric or manual release system.

2 Deluge systems are built around the Viking EZ-
Trim™ using Deluge Valves Model E-3 for 1½" (40 mm)
diameter (Model E-4 is the Halar
®
Coated version for use in
corrosive environments) or Model E-1 for 2" (50 mm)
diameter and up (Model E-2 is the Halar
®
Coated version for
use in corrosive environments).
All the valves are rated up to a maximum of 250 psi WWP
(1724 kPa) and are available in the following diameters:
1½" (40 mm)
2" (50 mm)
3" (80 mm)
4" (100 mm)
6" (150 mm)

2 Deluge systems are supplied with flange–groove
Deluge Valves. Units with flange–flange Deluge Valves are
also available on request.
7. Release Systems
7a
Hydraulic Release.
Hydraulic
ally controlled Deluge
systems require a hydraulic release system, equipped with
fixed temperature releases, and/or pilot heads.
In fire conditions, operation of a releasing device on the
hydraulic release system opens the Deluge Valve, allowing
water to enter the system piping. Water will flow from any
open sprinklers and/or spray nozzles on the system.
7b
Pneumatic Release. 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.
Note: The air supply for the pneumatic release piping
system must be provided by the contractor and installed
outside the T
OTAL

AC
2 unit. 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 or
sprinkler operates. It is also recommended to provide
Inspectors Test Connections on both the release system
and the sprinkler system.
In fire conditions, operation of the pneumatic release system
opens the Deluge Valve, allowing water to enter the system
piping. Water will flow from any open sprinklers and/or spray
nozzles on the system.
7c
Electric Release. Electrically controlled deluge systems
require an electric Solenoid Valve (F1) controlled by an
approved System Control Panel with compatible detection
devices (if provided with this system, see Controls Section for
details).
In fire condition, when the detection condition is satisfied the
system Control Panel energizes the Solenoid Valve (F.1)
open, causing the Deluge Valve (A1) to open allowing water
to enter the system piping. Water will flow from any open
sprinklers and/or spray nozzles on the system.
