Application: Man Hours 1
This applies to control panels for specialized fire suppression
systems (Halon 1301, CO2, Preaction, Deluge, and systems with special shutdown
features.
Special Instructions:
If a test that includes actual discharge of the system is desired, special
precautions must be taken with the using agency to prevent shutdown and discharge
during routine work performance and subsequent equipment or software damage. If
an actual discharge test is not desired, be sure to prevent gas discharge and
ventilation system and computer system shutdown.
The work required by this procedure may cause the activation of the building fire
alarm system and/or central station transmitter. The control center must be
notified prior to start of work. When work requires the actuation of building
evacuation systems, the work must be performed after hours and must be
coordinated through the Office Manager to prevent the unnecessary evacuation of
the building's occupants.
Items to Check & Initial Completion:
1. ___ Inspect the cabinet for damage (exterior and interior) including locks,
door hinges, and plastic covers.
2. ___ Check all lamps/LED's (including remote annunciators).
3. ___ Check all fuses.
4. ___ Check power supply output voltage in normal and under load conditions.
5. ___ Check standby battery voltage under load for a minimum of 5 minutes (if
applicable).
6. ___ Check battery charge current (be sure it is within manufacturer's limits).
7. ___ Check trouble signals by opening all supervised circuits one at a time.
(Class A circuits open two return wires; Class B circuits open end of the
line device.)
8. ___ Check for proper alarm on all input circuits.
9. ___ Check for return to normal operation after each alarm circuit input.
10.___ Check for proper reset (either automatic or manual) of the trouble signal
when the circuits are closed.
11.___ Check for proper contact closure and signal transmission for all panel
modes of operation (trouble, alarm, ground, etc.).
12.___ Check for proper Ground Fault Annunciation where panels have such a
feature.
13.___ Check all meters in panel for proper operation and deflection.
14.___ Check modules in panel for signs of heat or deterioration.
15.___ Check standby batteries (if located in the panel) for signs of
overcharging, heat, and leakage.
16.___ Test electrically operated release devices (control heads). Note:
Combine release test with detector test.
17.___ Test manual overrides electrically to cause direct actuation of release
devices.
18.___ Test cross-zoned systems by actuating detectors on alternate circuits to
actuate release devices and auxiliary functions. Observe functions as
each zone is actuated.
19.___ Test abort feature by operating the abort approximately in the middle of
the time interval. At the end of the time interval, confirm that the
aborted functions did not occur.
20.___ Test the manual override device over the abort feature.
21.___ Clean interior of panel.
22.___ Return all circuits and subsystems to normal. Leave panel in normal
operating condition with door locked. Inform involved personnel that
testing is complete.
