6.1 Dry-pipe Vacuum Sprinkler System
Note:
Numbers indicated between brackets refer to items
on the
TRIM SCHEMATICS
from section
B
MECHANICAL
and
section
D
VACUUM SUPPLY
.
The vacuum sprinklers piping network is under vacuum
pressure. This dry-pipe vacuum sprinkler system utilizes a
Viking deluge valve
(A1)
which opens by the operation of
the solenoid valve
(F1)
or the manual emergency release
valve (
B10)
.
The vacuum level inside the piping network is supervised
by the
FLX-PC
®
VACUUM / PRESSURE CONTROLLER
for low,
high and alarm vacuum levels. One objective of this
device is to perform the opening of the deluge valve in less
than 5 seconds following the opening of a vacuum
sprinkler, thereby permitting a more rapid fire attack.
The electric release system operates by the alarm
pressure of the
FLX-PC
®
VACUUM / PRESSURE CONTROLLER
.
If a vacuum sprinkler is fused, or damage to a vacuum
sprinkler or to piping network occurs, the
FLX-PC
®
will
operate and the deluge valve
(A1)
will open, flowing water.
The electric release system also operates when a manual
pull station is triggered, opening the deluge valve
(A1)
.
Water will be contained in the piping network until the
opening of a vacuum sprinkler.
In the event of no operation of the electric release system
or if the release control panel is no more powered from AC
power and batteries, the dry-pipe vacuum sprinkler system
can be manually trip by triggering the manual emergency
release valve (
B10)
, causing the deluge valve
(A1)
to
open
.
Water will be contained in the piping network until
the opening of a vacuum sprinkler.
7- System release
7.1 Electric release
Electric release trim for dry-pipe vacuum sprinkler system
utilizes an electric solenoid valve
(F1)
controlled by the
approved release control panel provided with this system
(see section
E
CONTROLS
and VFR-400 manual for
details).
In fire condition, when a vacuum sprinkler is fused, or
damage to a vacuum sprinkler or to piping network occurs,
an alarm pressure signal from the
FLX-PC
®
VACUUM /
PRESSURE CONTROLLER
to the release control panel
energizes the solenoid valve
(F1)
, causing the deluge
valve
(A1)
to open. Water will flow from the previous
opening.
When a manual pull station is triggered, the release control
panel energizes the solenoid valve
(F1)
, causing the
deluge valve
(A1)
to open. Water will be contained in the
piping network until the opening of a vacuum sprinkler.
