Description
Electrical actuation of an agent cylinder and/or selector
valves is accomplished by an HF electric actuator interfaced
through an AUTOPULSE Control System. This actuator can
be used in hazardous environments where the ambient tem-
perature range is between 0 °F to 130 °F (–18 °C to 54 °C).
The HF electric actuator meets the requirements of N.E.C.
Class I, Div. 1, Groups B, C, D and Class II, Div. 1, Groups
E, F, G. A maximum of two HF electric actuators can be
used on a single AUTOPULSE release circuit. When utiliz-
ing only one HF electric actuator, an in-line resistor, Part No.
73606, is required in the supervised release circuit.
The actuator specifications are:
Nominal Rated Voltage
Voltage
Minimum Maximum
12 VDC @ 0.57 amps 12.0 VDC 14.0 VDC
In auxiliary or override applications, a manual-local override
valve actuator or a manual cable pull actuator can be
installed on top of the HF electric actuator by removing the
safety cap.
A reset tool is required to reset the actuator after operation.
The actuator contains a standard 1/2 in. threaded female
straight connector for electrical conduit hookup.

Description
The Booster Actuator, Part No.
428949, is used when electric actua-
tion is required on the selector valve
or the CV-98 cylinder valve. The
actuator mounts directly to the com-
ponent and then a HF electric actua-
tor mounts to the top of the booster
actuator.
The Booster Actuator requires reset-
ting after actuation. A Reset Tool,
Part No. 429847, is available for this
use.
