Valve Trim
The Double Interlock Preaction System
with Electric/Electric Actuation Trim
(Fig. 3A or 3B) forms a part of the labo-
ratory listings and approvals. The trim
is necessary for proper operation of the
DV-5 Valve.
Each package of trim includes the fol-
lowing items:
• Water Supply Pressure Gauge
• Diaphragm Chamber
Pressure Gauge
• Diaphragm Chamber Connections
• Manual Control Station
• Main Drain Valve
• System Drain Valve
• Alarm Test Valve
• Automatic Drain Valve

The following three items and all items
listed above are included in the Pre-
trimmed Valve Assembly and can be
ordered separately for the valve trim:
• 24VDC Solenoid
• Model BFV-N Butterfly Valve
• Figure 577 Grooved Coupling
To ease field assembly of the trim
arrangement, the trim components are
provided partially assembled as shown
in Figure 3B.
The trim arrangement is provided with
galvanized or black nipples and fittings.
The galvanized trim is intended for
non-corrosive or corrosive conditions,
whereas the black trim is principally
intended for use with AFFF systems.
NOTE: When the system pressure is
greater than 175 psi (12,1 bar), provision
is to be made to replace the standard
order 300 psi (20,7 bar) Water Pressure
Gauges, shown in Figure 3A or 3B with
separately ordered 600 psi (41,4 bar)
Water Pressure Gauges.
System Design Considerations
Because a double interlock preac-
tion system requires time for a drop in
system air pressure to occur (concur-
rently with the response time for the
separate fire detection system) before
it will allow water to enter the system
piping, this system has characteristics
similar to a dry pipe sprinkler system.
Therefore, the system design con-
siderations for a dry pipe system are
normally applied to a double interlock
preaction system, — including: a 30%
increase in design area; a maximum 1
minute water delivery time for system
capacities of 750 gallons (2800 liters)
or more; and, prohibition of gridded
system piping.
As an option, the DV-5 Double Interlock
Preaction System with Electric/Elec-
tric Actuation may be equipped with
the Model QRS Electronic Accelerator
to reduce the time to valve actuation
following the operation of the elec-
tric detection system and one or more
automatic sprinklers. Refer to Technical
Data Sheet TFP1100 for details regard-
ing installation requirements and pres-
sure ratings.
In order to readily perform the System
Inspection Procedure described in
the Care and Maintenance section, it
is recommended that a System Shut-
Off Valve be installed above the Riser
Check Valve, as shown in Figure 1. The
System Shut-Off Valve should be a
listed or approved (as appropriate) indi-
cating valve with a supervisory switch
to monitor the normally open position.
Detection System
The Double Interlock Preaction System
With Electric/Electric Actuation Trim
provides for electric operation of the
DV-5 Valve by a detection system
consisting of electrical devices such
as heat sensitive thermostats, smoke
detectors, and/or electric manual pull
stations. Information on the various
types of separately ordered Solenoid
Valves that may be used with this trim
package is given in Technical Data
Sheet TFP2180. Nominal installation
dimensions for the Double Interlock
Preaction System With Electric/Electric
Actuation Trim are shown in Figure 4.
The cross-zone deluge valve releas-
ing panel (automatic control unit)
with battery back-up, fire detection
devices, manual pull stations, and sig-
naling devices, that are utilized with the
Double Interlock Preaction System with
Electric/Electric Actuation must be UL
Listed, ULC Listed, C-UL Listed, or FM
Approved, as applicable.
NOTES: Approval by Factory Mutual
is contingent on the use of an FM
Approved 24VDC Solenoid Valve (P/N
52-287-1-024 or P/N 52-287-1-124). FM
only approves solenoid valves for use
in non-hazardous locations.
Consult with the authority having juris-
diction regarding installation criteria
pertaining to electric actuation circuitry.
