Notes
:
■ Any deviation in trim size or arrangement may adversely affect the proper operation of the system.
■ All the pilot system devices, must be UL Listed and compatible with the particular system. Refer to current “UL
Listed Fire Protection Equipment Directory”.
2.1 Installation Instructions
2.1.1 Allow enough room around the valve assembly for any adjustments and future
maintenance/disassembly work.
2.1.2 Before the valve is installed, flush the pipeline to remove any dirt, scale, debris, etc. Not flushing the
line may result in the valve being inoperable.
2.1.3 Install the valve in the pipeline with the valve flow arrow on the body casting in the proper direction.
Ensure that the valve is positioned so that the cover/actuator can be easily removed for future
maintenance.
2.1.4 Ensure that the EMR is Mounted Vertically (with the reset button up), and all other components are
positioned correctly as per the appropriate drawing.
2.1.5 Install a Listed Indicating Valve upstream of the Pre action System (supervised “open”).
2.1.6 Install also another Listed Indicating Valve downstream of the Pre action System (supervised “open”)
to shut off and isolate the sprinkler piping in order to allow water flow testing and maintenance.
2.1.7 The water supply priming line must be connected to the upstream of the main isolating valve.
2.1.8 Subjected to all other instructions, drawings and technical specifications, which describe Bermad
Valve, install in their proper positions the components comprising the Water Control Trim Package,
according to the drawing relevant to the specific type, hereby enclosed.
2.1.9 Install also the additional accessories, which appear in the drawing and which must be installed as
shown in the drawing, although they are not packed together with the Bermad Valve itself. After
installation in the main line, carefully inspect/correct any damaged accessories, piping, tubing, or
fittings; ensure that there are no leaks.
2.2 Electrical Requirements
All releasing and detection devices in the double-interlock system shall be controlled by a Releasing
Control Panel. Wire all connections according to information and detailed wiring diagrams in publications
provided by the releasing Control Panel manufacturer.
Connect the Low-Air-Supervised-Pressure Switch (P2) terminals Common and NC to the control panel
These contacts must be in the open position when the system is pneumatically pressurized.
