SECTION 8 – RECHARGE, INSPECTION, AND MAINTENANCE
2014-MAY-01 REV. 01 PAGE 8-1
RECHARGE
Individuals responsible for recharging, inspecting, and main-
taining a CHECKFIRE 110 System, must hold current ANSUL
Certification from an ANSUL A-101 or LVS training program.
For continued protection, the CHECKFIRE 110 System and
fire suppression system must be recharged immediately after
activation.
Before performing the recharge steps, inspect the CHECK-
FIRE 110 Detection and Actuation System to determine cause
of system release.
1. Disconnect the CHECKFIRE 110 Control Module Release
Circuit Lead from release circuit.
2. Check all Electric Manual Actuators (EMAs) for evidence of
operation and determine if visual inspection seal is intact.
For EMAs needing reset and/or re-sealing complete the
following:
a. Reset switch to normal position (pull button out)
b. Insert ring pin
c. Wait to seal until after system test
3. If optional pneumatic actuation is part of the system follow
recharge instructions in the appropriate A-101 or LVS
Design, Installation, Recharge, and Maintenance manual
(latest edition).

LVS Manual (Part No. 427109)
4. Closely examine all Detection Circuit Cable, Linear Detec-
tor, and Spot Thermal Detectors for loose connectors
and damage (i.e. cut, abraded, burnt, blackened, melted,
deformed, etc.) The Detection Circuit Fault LED on the
CHECKFIRE 110 Control Module will indicate a fault condi-
tion if there is an open or grounded circuit in the Detection
Circuit.
a. Inspect all Detection Circuit Cable for damage and
replace if there are visible and mechanical signs of
damage (brittleness, deformation, discoloration, etc.).
CAUTION
Failure to replace damaged cable can result in unin-
tended discharge.
b. If a fire event was the cause of discharge, all Linear
Detector cables in the hazard area must be replaced;
otherwise, inspect for damage and replace if damaged.
Note: Splicing of Linear Detector cable is not allowed.
c. If a fire event was the cause of discharge, all Spot
Thermal Detectors and related cable installed in imme-
diate area(s) of fire must be replaced. When subject
to high temperatures, set-point drift and damage may
occur that is not visible for field observation. (The
“resettable” feature of the detector is for field-testing
(with appropriate test equipment), not for resetting after
a fire.) Note: Spot Thermal Detectors will be field-tested
in step 8.
CAUTION
Failure to replace spot thermal detectors can result in
system failure.
d. The Detection Circuit Fault clears once all faulty compo-
nents have been replaced.
5. Closely examine all Release Circuit Cables for loose
connectors and damage (cut, abraded, burnt, blackened,
melted, deformed, etc.). Replace cables as needed.
6. Check and perform maintenance on each Electric-Pneu-
matic Actuator (Part No. 439569) (installed on each agent
tank expellant gas cartridge): Note: If system was electri-
cally operated all of the PADs should be actuated.
a. If attached, remove Release Circuit Drop Cable from
Electric-Pneumatic Actuator.
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 force-
fully separates from actuating end. Physical injury may
occur from contact with the actuating pin and/or the
detaching disk.
CAUTION
The Release Circuit Drop Cable with PAD must be
removed from Electric-Pneumatic Actuator to retract
actuator puncture pin. An actuated PAD can lock the
Electric-Pneumatic Actuator puncture pin in the actuated
position until removed from actuator.
b. Confirm PAD o-ring is in place; if absent, check inside
actuator and remove. (New PAD comes with new
o-ring.) See Figure 8-1.
CAUTION
Failure to remove loose o-ring from inside actuator body
can result in improper positioning of the PAD and incor-
rect system operation.
