Technical Data
Reliable Single Interlock Preaction Systems, with asso
-
ciated trim, sizes 4” (100mm), 6” (150mm) and 165mm
are rated for use at minimum water supply pressure of 20
psi (1,4 bar) and maximum supply pressure of 250 psi
(17,2 bar). Water supplied to the inlet of the valve and to
the pushrod chamber must be maintained between 40°F
(4°C) and 140°F (60°C).
The following list of technical bulletins pertains to valves
and devices that may be used in this preaction system:

(34,5 bar). (Valve only)
3. End and trim connections:
•
ANSI/AWWA C606 grooved inlet and outlet
•
Threaded openings Per ANSI B 2.1

Maintenance
Reliable Single Interlock Preaction Systems and asso
-
ciated equipment shall periodically be given a thorough
inspection and test. NFPA 25, Inspection, Testing and
Maintenance of Water Based Fire Protection Systems,
provides minimum maintenance requirements. System
components shall be tested, operated, cleaned, and in
-
spected at least annually, and parts replaced as re
-
quired.
Resetting the Single Interlock Preaction
System
Refer to Figs. 2, 6, and 7.
1. Close the main valve controlling water supply (Fig.
7) to the Deluge Valve and close off the air supply to
the sprinkler system at the air supply’s source.
2. Close the pushrod chamber supply valve, valve A
(Fig. 7).
3. Open the main drain valve, valve B (Fig. 7), and
drain system.
4. Open all drain valves and vents at low points
throughout the system, closing them when flow of
water has stopped. Open valve D (Fig. 7). Note:
The above steps accomplish the relieving of pres-
sure in the pushrod chamber of the Deluge Valve.
5. With Valve F (Fig. 7) open, push in the plunger of ball
drip valve, valve G (Fig. 7), to force the ball from its
seat, and drain any water in the alarm line.
6. With the Model B Manual Emergency Station, valve
D(Fig.7), open, push in and rotate the deluge
valve’s external reset knob (#38, Fig. 6) clockwise
until you hear a distinct clickingnoise, indicating that
the clapper has closed. Note:
The reset knob can
be rotated only after pressure in the pushrod cham
-
ber has been reduced to atmospheric conditions (0
psig).
7. Inspect and replaceany portion of the sprinkler sys
-
tem subjected to fire conditions.
8. Close valve F (Fig. 7). Activate a solenoid-release
pull station (Or other means of electric detection.) to
energize the solenoid valve(s). Silence any alarms
or audible tones on the releasing/control panel.
Open valve A (Fig. 7) to begin pressurizing the
push-rod chamber and its associated piping, while
simultaneously venting any entrapped air. Note:
This venting of the air from the actuation piping is
very important to ensure proper system operation
and avoidanceof falsely tripping the DelugeValve.
