Tyco DV-3 User Manual

Electric
Actuation
The Electric Actuation Trim is required
for electric operation of the DV-3 Valve
by a detection system consisting of
electrical devices such as heat sensi-
tive 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 pack-
age is given in Technical Data Sheet
TFP2180. Nominal installation dimen-
sions for the Electric Actuation Trim
are shown in Figure 10.
NOTE
Approval by Factory Mutual is contin-
gent on the use of an FM Approved
24VDC Solenoid Valve. FM only ap-
proves solenoid valves for use in non-
hazardous locations.
TheElectricActuationTrimisonlyto
be used in conjunction with an electric
deluge valve releasing panel (auto-
matic control unit) that is listed or ap-
proved (as appropriate) for fire protec-
tion system releasing service. In
addition, the deluge valve releasing
panelisonlytobeoperatedbylisted
or approved (as appropriate) fire de-
tectors.
Operation of an electrical device such
as a heat sensitive thermostat, smoke
detector, or electrical manual control
station signals the deluge valve re-
leasing panel to energize the Solenoid
Valve. In turn, the energized Solenoid
Valve opens resulting in a rapid pres-
sure drop in the Diaphragm Chamber
of the DV-3 Valve, and the force differ-
ential holding the Center Valve As-
sembly down in the set position is re-
duced to below the valve trip point.
NOTES
Consult with the Authority Having Ju-
risdiction regarding installation criteria
pertaining to electric actuation cir-
cuitry.
When a Solenoid Valve is energized to
operate the DV-3 Valve, the Solenoid
Valve must remain energized in order
for the DV-3 Valve to remain open.
