TEST ACTUATION OF FIRE SUPPRESSION SYSTEM
(Continued)
9. Restore the agent tank(s) actuation mechanism to the
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 the ANSUL AUTOMAN 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 ANSUL AUTOMAN 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 the Ansul 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.
