Electric
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.
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.
