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.

!
Anumber 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 theAnsul Fire Suppression System.

MOUNTING “ANSUL AUTOMAN” II-C RELEASE
The reliability of an Ansul fixed nozzle fire suppression sys-
tem depends greatly upon proper installation of the releasing
device, associated equipment and wiring. Unless noted oth-
erwise in the fire suppression system manual, the mounting
location for the ANSUL AUTOMAN II-C release must be
maintained within a temperature range of 32 °F to 120 °F
(0 °C to 49 °C). This requirement and the following instruc-
tions are critical for reliable operation.
Installing the Release
1. Select a shock and vibration free surface in a clean dry
area for mounting the ANSUL AUTOMAN II-C release
enclosure. The mounted release should be completely
visible and accessible for maintenance.
NOTICE
The STRIKE button must be accessible for
manual operation. Follow local, state, or
federal regulations for proper location. If the
release cannot be mounted in this manner,
a remote manual pull station should be
installed to facilitate manual actuation.
2. Open the release cover and secure the enclosure at the
selected location utilizing the four mounting holes. Use
lag screws or toggle bolts depending on the mounting
surface. Figure 3 provides detailed mounting data.

WIRING THE “ANSUL AUTOMAN” II-C RELEASE
TheANSULAUTOMAN II-C is designed for use with the sep-
arately listed or approved fire detection and releasing control
unit which will initiate the electrical signal to operate the
release. Accordingly, conduit and wiring connections
between the release and the detection/alarm control system
should be made by or under the supervision of the detec-
tion/control system manufacturer’s technician.
Installation of Wiring
Aterminal strip is provided inside the ANSUL AUTOMAN
II-C enclosure for making field terminations. It is to be con-
nected to a nominal 12 VDC or 24 VDC releasing circuit. The
activation current is 450 mA at 12 VDC or 750 mA at 24 VDC
for approximately 55 milliseconds. The wiring diagram shown
in Figure 7 provides the details for making the field wiring
connections.
All interconnecting wiring to the solenoid is to be a minimum
of 18 AWG. All wiring should be done in accordance with the
National Electric Code and/or local codes and standards.
The circuit connections from the output of the Releasing
Control Unit are made to Terminals 4 and 8 of the ANSUL
AUTOMAN II-C release. The release is shipped with a
jumper (J2) installed across Terminals 4 and 5. If the releas-
ing control unit that is to be connected to the release requires
an in-line supervisory device to maintain proper circuit super-
vision, jumper J2should be removed and the appropriate in-
line supervisory device installed in its place. Refer to the
installation instructions from the manufacturer of the releas-
ing control unit for polarity requirements when installing an
in-line supervisory device.
Install the in-line supervisory device (SDxin Figure 7) across
terminals 4 and 5. Refer to the releasing control unit installa-
tion instructions for supervisory device requirements. If an in-
line supervisory device is not required, install jumper J2
across terminals 4 and 5.
Terminals 1 through 3 are provided for auxiliary device con-
nections. Auxiliary equipment is controlled through the action
of switch S1. Refer to the following ELECTRICAL DATA
SECTION for the contact ratings of S1.
Replace the protective cover over the terminal strip upon
completion of field wiring. Test the system by following the
procedures on the following pages.
ELECTRICAL DATA
Input Current: 750 mAat 24 VDC for 50 milliseconds
450 mAat 12 VDC for 50 milliseconds
Input Voltage: 12.5 – 30 VDC
Polarization: Polarization will result only by installation of
a polarized in-line supervisory device (SDx).
Observe polarity when connected to a
release circuit; terminal 4 positive, terminal 8
negative.
Contact Ratings: S1and S2contact ratings are 15A, 1/3
HP, 125 or 250 VAC resistive; 1/2A, 125
VDC; 1/4A, 250 VDC; 5A, 120 VAC
inductive
SOL1Coil Resistance: 28 ohms ± 10% at 77 °F (25 °C)
Operating Sequence
With solenoid cut-off switch (S2), in the normal position (the
release reset lever in the armed position), an electrical circuit
is formed between terminals 4 and 8. As the supervisory
release circuit of the control unit is activated, power is
applied between terminals 4 and 8 of TB1causing solenoid
SOL1to operate the ANSUL AUTOMAN II-C release. As the
release operates, S1and S2will change positions with S2
cutting power to the solenoid, which opens the release cir-
cuit. S1, being a condition switch, provides an isolated set of
form “C” contacts for auxiliary functions at terminals 1, 2 and
3 of TB1.

and the technical representatives of both the detection/alarm
control system and the fire suppression system manufactur-
ers.
1. Raise the release manual reset lever up to the armed
position by using the cocking lever (Part No. 26310). Do
not install ring pin. See Figure 8.
2. Energize the detection/alarm control system.
3. Activate a detector in accordance with procedures as
recommended by the detection/alarm control system
manufacturer. Check that the ANSUL AUTOMAN II-C
release has operated — reset lever should be in the
down (FIRED) position as illustrated in Figure 8. If the
release does not operate refer to the SOLENOID
CHECKOUT PROCEDURE on page 6.

TEST ACTUATION OF FIRE SUPPRESSION SYSTEM
Depending upon the hazard requirements, the actuation sys-
tem design for the agent tank assembly will differ. For this
reason, the operational test of the actuation system must be
performed by an authorizedAnsul representative.
1. Refer to the Installation, Operation and Maintenance
Manual(s) furnished with the Ansul Fire Suppression
System and disarm/remove the agent tank assembly
actuation mechanism before test firing.
2. Check ANSUL AUTOMAN II-C release — reset lever
should be in the ARMED position and ring pin inserted in
the puncture pin assembly shaft.
3. Weigh the proper cartridge (replace cartridge if weight is
1/4 oz (7.1g), or more, below weight stamped on car-
tridge). Install fully charged cartridge in the release and
hand tighten. (Refer to the Installation, Operation and
Maintenance Manual provided with the Ansul Fire
Suppression System for selection of proper cartridge.)
4. Remove ring pin from release mechanism and close the
release cover.
5. Operate the release by depressing the STRIKE button.
6. Confirm that the detection/alarm control system per-
formed all of its associated functions and that the agent
tank assembly actuation system functioned properly.
7. If the actuation piping contains a relief valve, leak test
the pneumatic pipe and fittings between the release and
agent tank assembly.
8. Verify that the actuation pressure has been fully relieved.
If the system has a relief valve in the actuation line, pull
the ring to release all pressure. If the system has an
actuation line vent plug, the pressure will be relieved
CAUTION
!
Fire suppression systems contain agents under high pres-
sure. Make certain electric actuators are removed from
valve and gas cartridges are removed from release mech-
anism before performing release circuit wiring or checkout.
Failure to comply could result in accidental agent dis-
charge.
CAUTION
!
Do not install cartridge until all testing has been completed
and the system is ready to be armed as instructed on the
following pages. CAUTION

normal position and reinstall on each agent tank.
10. Rearm release (using cocking lever Part No. 26310) and
insert ring pin in release mechanism.
11. Remove spent cartridge.
12. Continue with SOLENOID CHECKOUT PROCEDURE.
SOLENOID CHECKOUT PROCEDURE
If one of the following has occurred during maintenance or
installation, the solenoid for the releasing device may be
damaged, rendering the system inoperative.
1. The release was tripped electrically (fired) with the ring
pin inserted such that the release mechanism was
pinned in the cocked position.
2. The lever arm of the mounted switch was bent such that
the cut-off switch does not operate when the release roll
pin was bottomed out in the fired position.
3. If an attempt was made to recock the release mecha-
nism while power was applied to the release through the
alarm contacts.
In any event, the solenoid should be checked to ensure that
it is operating properly as follows:
1. Electrically operate theANSULAUTOMAN II-C release.
2. Using an ohmmeter, measure the resistance of the sole-
noid coil. The resistance should be 21-32 ohms.
NOTICE
If the solenoid is found to have burned out
as a result of the preceding situations, a
replacement can be ordered (Part No.
25924).
ARMING THE SYSTEM
1. Make sure release is armed with ring pin inserted.
2. Weigh new cartridge and replace if cartridge weight is
1/4 oz. (7.1 g) or more, below weight stamped on car-
tridge. Install fully charged cartridge and hand tighten.
(Refer to the Installation, Operation and Maintenance
Manual provided with the Ansul Fire Suppression
System.)
3. Remove ring pin and close cover.
4. Insert ring pin in STRIKE button and attach lead and
wire seal (Part No. 197).
CARTRIDGE AND PRESSURE RELIEF DEVICE
SELECTION
The ANSULAUTOMAN II-C can be used as a release mech-
anism in a variety of ways and with a variety of suppression
systems. The limitations of the release mechanism, when
used as a releasing device for a particular type of system,
are partly dependent upon the operating parameters of the
equipment that it is used to operate. Several important con-
siderations for use are temperature, length of actuation pipe
(pipe volume), and pressure requirements. For proper selec-
tion of cartridge and pressure relief device, refer to the
Installation, Operation and Maintenance Manual provided
with theAnsul Fire Suppression System.
INSPECTION
Inspection, to provide reasonable assurance that your
release is armed and operable, should be conducted at least
monthly or more frequently by visually determining that the
ring pin is properly inserted and sealed in the STRIKE button
and that the reset lever is in the up (ARMED) position.
NOTICE
Every Ansul fixed nozzle system is subject
to a mandatory inspection after installation.
This inspection must be performed by an
authorized Ansul representative to ensure
that the complete system is installed prop-
erly and is ready for service.
