4. Functional Test of the Detection System. Hold a container of hot or boiling water under the
heat detector, immersing the actuating chamber in the water. At least 50% of the detector
should be immersed. The water must be at least 100F above the ambient temperature.
Note the time between the application of the hot water to the detector and the operation
of the control head. The control head should operate in approximately 15 seconds. Do not
apply heat for more than 15 seconds. The detector is not functioning if the control head
has not operated within this time.
When testing two control heads connected in tandem, both may not operate
simultaneously. Both control heads should operate within 30 seconds if the heat is
sustained.
5. The heat test should be performed on each heat detector. Between each test, wait about
ten minutes for the system to return to normal, and then reset the control head(s). To
reset, insert screwdriver in reset stem and turn clockwise until the stem locks in position
with the arrow on reset stem lining up with the "Set" arrow on the nameplate. (Slight
resistance will be met just before the stem locks.)
6. If the application of heat does not cause the control head to operate within 15 seconds,
remove the container of water and investigate the cause.
6-5.4.4 TROUBLESHOOTING OF PNEUMATIC DETECTION SYSTEM
Failure of the pneumatic detection system to operate when applying heat to the detectors may
be caused by:
• Insufficient heat applied to the detector
• Leakage in the tubing system (tubing connections not tight).
• Obstruction in the tubing.
The manometer can be used to assist in trouble shooting the system as follows:
1. Install manometer in system tubing at pneumatic control head connection. Replace union
connection with a control head "T." Connect manometer tube B to the "T" fitting. Close
open tube A of the manometer with a crimp clamp. The manometer is now an integral part
of the system and provides a visual record of pressure to which system is subjected by
heat or cold at the detector.
2. The installation of the manometer as described above provides a visual indication of the
pressure build-up within the system and will assist in determining if there is sufficient or
insufficient pressure build-up during the test of the system.
6-6 5 YEAR AND 12 YEAR INSPECTION AND TEST GUIDELINES
6-6.1 Carbon Dioxide and Nitrogen Cylinders
The United States' Code of Federal Regulations (CFR) Title 49 - Transportation and Canada's
Transport Canada (TC) Transport of Dangerous Goods Act (TDG) Part 5 govern the design,
fabrication, testing and stamping of hazardous goods transported over all public ways (roads,
rail, boat, etc.). When filled, CFR49/TDG classify Kidde cylinders as hazardous goods. In any
case of information within this section conflicting with CFR49/TDG, the requirements of
CFR49/TDG take precedence over the instructions provided within this section.
All Kidde cylinders are designed, fabricated, tested and stamped in compliance with
CFR49/TDG.
WARNING
When using hot or boiling water, exercise care when immersing the Pneumatic
Detector Actuating Chamber. Do not stand directly beneath the water container.
