  TEST REPORTS

  Sec. 12-72-301.

  (a) The report shall include engineering data, and an analysis comparing the design against Sections 12-72-302 (a) through 12-72302 (t); it shall include wiring diagrams, operating manuals and photographs; it shall set forth the tests performed in accordance with this standard and the results thereof and shall verify the correctness of the electrical rating.

  (b) Listed components. Electrical wiring, material, devices, combination of devices, fittings, appliances and equipment which have been tested and listed by an approved listing agency for the intended purpose and use need not be individually retested.

  The report shall include the catalog number or other readily identifiable marking; the name of the approved listing agency, the laboratory test report number and date. Such individually tested and listed component parts and devices shall be subjected to the performance standard tests to determine its suitability for use in combination with other component parts, devices, circuits or equipment.

  (c) Listed detectors. Detectors which have been tested to any other acceptable test standard may be evaluated provided such test incorporates all features of this standard.

  (d) Rejection for cause. Compliance with these standards will not necessarily mean approval and listing, if when examined and tested, it is found to have other features which may impair the result intended by these regulations. Unusual constructions may require application of additional performance tests. The State Fire Marshal may refuse to approve any item for cause. (See the Cali- fornia Electrical Code .)

  (e) Smoke detectors only.

  1. A combustion products detector, as covered by these requirements consists of an assembly of electrical components arranged to detect one or more products of combustion. The products of combustion may consist of but are not necessarily

  2. A limited-energy detector circuit shall conform to the following: A. The open-circuit voltage between any two wiring terminals and between any terminal and a grounded circuit part or noncurrent carrying metal part shall not exceed 50 volts when the control unit is connected to a power supply source of rated voltage and frequency. B. Overcurrent protection not in excess of 2 amperes shall be provided in such manner that each limited-energy circuit is protected. Current-limiting transformers may be substituted, provided that under condition of short circuit, current flow at the terminals will not exceed 2 amperes.

  (i) Jarring. The control unit or control equipment installed or supported in the position of its normal use connected to a power supply and in supervisory condition shall withstand jarring from impact or vibration such as may be experienced in service by striking the enclosure. Striking the enclosure shall not cause signaling operation of any part nor adversely affect any subsequent normal operation.

  (j) Temperature.

  1. Materials employed in the construction of a control unit or combination signaling system which have not been investigated and reported on by a nationally recognized testing laboratory as an assembly in the form intended for use shall be investigated and tested to determine temperature rises that may adversely affect the materials of construction, normal signaling operation of the equipment and fire hazard to building materials.
  2. A control unit shall be mounted on a wood panel representative of its manner of installation in service. It shall be connected to a power supply as indicated in Section 12-72-103 (a), Item 4, and operated under representative normal conditions liable to produce the highest temperatures.

  3. A combination signaling system shall be set up representative of normal service conditions against a wood panel wall as specified in Section 12-72-103 (a), Item 3, connected to a supply circuit as indicated in Section 12-72-103 (c), Item 1, and operated under representative normal conditions liable to produce the highest temperatures.

  4. In control units equipped with time-limit cutouts which are not intended to limit the time of alarm-signal operation, the time-limit cutout shall be shunted out of the circuit for the duration of the test.

  5. A control unit or combination signaling system intended to provide impulse signals shall be operated by a testing device to provide one impulse per second, except that if the signal impulses are normally produced by a device which is a part of the control unit or equipment assembly, the test impulses are to be at the rate of normal operation of the device.

  6. Circuits shall be loaded representative of maximum load under normal service conditions. Resistors shall be adjusted for maximum wattage dissipation possible under conditions of normal service.

  7. Except for coils, temperature readings are to be preferably obtained by means of thermocouples. Temperatures are to be considered as constant when three successive readings taken at intervals of 10 percent of the previously elapsed duration of the test, but not less than 5 minute intervals, indicate no change. Temperature rise on coils may be determined by the resistance method or mercury thermometers.

  8. Horizontal screened or ventilation openings subject to accumulation of dust and lint shall be covered with loose cotton.

  9. Materials of construction and fire hazard to buildings shall be considered to be adversely affected if the temperature rise exceeds the limits shown in the following, based on an assumed ambient temperature of 25°C: A.
