4.
Approvals
1. Underwriters Laboratories, Inc. Listed and Certified for
Canada* (cULus) as an assembled unit in the “Special
System Water Control Valves Assembled Units” category,
(VKYL).
2. Factory Mutual (FM) Approved, as PrePak Single Interlock
and Double Interlock Preaction Systems.
*
Electrical devices and control panel must be specified
to meet Canadian requirements. This option is avail-
able.
3. Approved for use in New York City based on UL Listing.
Note:
Although PrePak units are UL Listed, custom built units
are sometimes supplied upon request. The components within
these special units maintain their individual Listings/Approvals,
whereas the assembled units do not.
PrePak units are also available without their door-mounted Pot-
ter PFC-4410-RC Releasing/ Control Panel and Air Compressor.
These units will still retain their Listings/Approvals, however the
installing contractor should make sure that any remote controlled
Releasing/Control Panels used with these units are Listed/Ap-
proved and programmed to handle the required sequence of
operation necessary to operate the automatic sprinkler system.
Any unauthorized modification or addition made on-site to a
factory-built Listed/Approved unit will void the Listing/Approval.
Such modifications or additions may void the unit’s warranty as
well. Consult Reliable’s Technical Services Department before
proceeding with any such modifications or additions.
Technical Data
1. The Reliable Model DDX 4” (100 mm), 6” (150 mm) and 8”
(200mm) PrePaKs are rated for a minimum supply pres-
sure of 20 psi (1.4 bar) and a maximum supply pressure of
250 psi (17.2 bar). Note: 1 bar = 100 kPa.
2. Friction loss, expressed in equivalent length of Schedule 40
pipe and based on Hazen-Williams Formula with C=120
and a flowing velocity of 15 ft/s (4.6 m/s), is:
System Size Equivalent Length
4” (100 mm) 32.8 ft (17.7 m)
6” (150 mm) 54.7 ft (21.8 m)
8” (200mm) 79.3ft (24.2m)
These values account for the Model DDX valve, supply
manifold tee, butterfly control valve, and small pipe/mani-
fold located directly above Model DDX valve.
