INTRODUCTION
The ANSUL AUTOMAN II-C Releasing Device is designed
for use with Ansul fire suppression systems. It provides auto-
matic-pneumatic actuation of fixed nozzle fire suppression
systems when connected to a suitable listed fire
detection/alarm system.
DESCRIPTION
The ANSUL AUTOMAN II-C is shown in Figure 1 and 2. It is
comprised of a metal enclosure which contains a spring-
loaded puncture pin release mechanism, an actuation car-
tridge (order separately), an auxiliary function switch, and a
terminal strip for making electrical connections. Knockouts
for the connection of conduit are provided in the top, bottom
and sides of the steel enclosure. The enclosure also con-
tains four surface mounting holes.
OPERATION
When energized, a solenoid mounted on the actuator trips
the release mechanism puncturing the cartridge. Actuation
gas from the cartridge is directed through piping to pneumati-
cally activate the fire suppression system.
Manual actuation is provided by means of an integral
STRIKE button at the release enclosure which may be sup-
plemented by use of a remote manual cable pull station.

CAUTION
!
A number of basic variations are available in the ANSUL
AUTOMAN II-C assembly. Your ANSUL AUTOMAN II-C
may have either a carbon dioxide actuation cartridge or a
nitrogen actuation cartridge. In every case Ansul
Incorporated recommends that all systems employing car-
bon dioxide actuators be restricted to installations in areas
where the ambient temperature is never less that 32 °F
(0 °C) or greater than 120 °F (49 °C). If ambient tempera-
tures in the area of the actuation cartridge fall below 32 °F
(0 °C) or exceed 120 °F (49 °C), it is mandatory that a
nitrogen cartridge be used. Be certain when replacing car-
tridges that the proper type is used, and that it meets the
temperature range and weight requirements outlined in
the instruction manual for that type of system. The pres-
sure relief device in the actuation line may be either the
actuation line vent (which relieves automatically) or the
pressure relief valve (pull ring to effect total relief). Refer to
the Installation, Operation and Maintenance Manual pro-
vided with the Ansul Fire Suppression System.
