Actuation
The Electric Actuation Trim forms a part
of the laboratory approval of the DV-5
Valves and is necessary for their proper
operation.
The Electric Actuation Trim is required
for electric operation of the DV-5 Valve
by a detection system consisting of
electrical devices such as heat sen-
sitive thermostats, smoke detectors,
and/or electric manual pull stations.
Installation dimensions are provided in
Figure 19.

ELECTRIC ACTUATION
(Refer to Figure 15 thru 18 for specific Bills of Materials)
The Solenoid Valve provided in the
valve trim (P/N 52-287-1-124 described
in TFP2180) is rated as follows:
• Pressure: 17,2 bar
• Voltage: 24 VDC
• Power Consumption: 22 Watts
• Current Draw: 0,83 Amps
NOTES: Approval by FM is contin-
gent on the use of the Solenoid Valve
provided with the valve trim. FM only
approves solenoid valves for use in
non-hazardous locations.
Consult with the applicable standards
of the Approval agency regarding
installation criteria pertaining to elec-
tric actuation circuitry.

The Electric Actuation Trim is provided
with a Model ASV-1 Automatic Shut-Off
Valve; consequently, the release circuit
of the releasing panel need only provide
the standard ten minutes of alarm con-
dition intended to energize the Sole-
noid Valve to open. After the ten minute
duration, at which point should the
Solenoid Valve become de-energized
and close (especially while operating
under battery back-up), the Automatic
Shut-Off Valve will have already auto-
matically closed, thereby preventing
the DV-5 Diaphragm Chamber from
becoming re-pressurized, and prevent-
ing an inadvertent closing of the DV-5
during a fire event.
