ELECTRIC-PNEUMATIC ACTUATOR
Part No. 439569
(normally supplied with agent tanks or expel
-
lant gas cartridge/bracket assemblies)
Attaches to agent tank expellant gas cartridge and provides
release of gas into agent tank. See Figure 2-24.
For electrical activation install Release Circuit Cable Assem

tric-Pneumatic Actuator punctures a seal in the expellant gas
cartridge allowing expellant gas to flow into the agent tank.
The actuator includes a preventor to reduce the possibility
of installing actuator with the puncture pin not completely
retracted. note: Do not bend or remove the preventor; it is
required for correct operation of the actuator.
The actuator includes optional pneumatic actuation hose ports.
Temperature range:
Electrically with PAD
– 40 °F to 185 °F
(– 40 °C to 85 °C)
Pneumatic only
– 65 °F to 221 °F
(– 54 °C to 105 °C)

PROTRACTING ACTUATION DEVICE (PAD)
Part No. 439448
Provides electrical activation of the fire suppression system.
See Figure 2-25 and 2-26.
CAUTION
!
When handling the PAD, always point actuating end away
from yourself and others. on electrical initiation, PAD operates
very quickly and a small brass disk forcefully separates from
actuating end. Physical injury may occur from contact with the
actuating pin and/or the detaching disk.
• Generates force to drive the Electric-Pneumatic Actuator
puncture pin through an expellant gas cartridge seal,
allowing the expellant gas to flow into agent tank.
• Integral spade connectors easily field install into the Release
Circuit Drop Cable. See Figure 2-25.
