Trim Descriptions
The Type D Double Interlock Preaction Trims for the Reliable
Model DDX Deluge Valve are arranged for rapid, easy, and
compact attachment, and serve as connection points to
Reliable Model C Mechanical Alarms and other devices.
The Double Interlock Type D Preaction System trim
configurations can be ordered as individual parts, in time-
saving segmentally assembled kit forms, or fully assembled
to the Model DDX Deluge Valve (with or without a control
valve).
Maintenance
Reliable Double Interlock Type D Preaction Systems
and associated 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
inspected at least annually, and parts replaced as required.
Type D Double Interlock Preaction Trim
Type D Double Interlock Preaction trim (see Figures 2 and
3) utilizes a normally closed/powered-open solenoid valve for
releasing the Deluge Valve. The solenoid valve used in the
assembly is available in both a 175 psi (12.1 bar) or 300 psi
(20.7 bar) rating.
Note:
In order for the solenoid valve to maintain Reliable’s
warranty it must remain sealed as it came from the factory.
If there are concerns about the valve’s internal components,
immediate replacement is recommended.
