Clause / Requirement

17 Tests

17.1 General

17.1.5 Mounting arrangements

The specimen shall be mounted by its normal means of attachment in accordance with the manufacturer's instructions. If these instructions describe more than one method of mounting, then the method considered to be the least favourable shall be chosen for each test.

17.2 Functional test

17.2.2.4 Test schedule - Disabled condition

Where a disablement function is provided, disable and restore at least two emergency loudspeaker zones (unless only one zone is provided).

Check that the operation of the disablement controls result in the correct indication on the s.s.c.i.e., that only the relevant parts of the system are disabled and that, on restoration of the disablements, the function is restored.

17.3 Test schedule

17.3.4 Test for three specimens

If three specimens are supplied for environmental testing, then one test specimen is subjected to all the operational tests, which may be carried out in any order. The second specimen shall be subjected to one of the endurance tests, and the third specimen shall be subjected to the other endurance test. Before and after each environmental test, a functional test shall be carried out.

For the first specimen, the functional test after one environmental test may be taken as the functional test before the next environmental test.

17.4 Output power

17.4.2.2State of the specimen during conditioning Mount the specimen as specified in 17.1.5 and connect it to suitable power-supply, monitoring and loading equipment, as specified in 17.1.3.

The specimen shall be in the quiescent condition.

17.4.2.3Conditioning

Apply the following severity of conditioning:

•temperature: 40 °C ± 2 °C.

Precondition the specimen at the conditioning temperature (40 °C ± 2 °C) until temperature stability has been reached to prevent the formation of water droplets on the specimen. Terminate the s.s.c.i.e. output(s) with the minimum resistive and maximum capacitive load representing the loudspeaker lines and loudspeakers.

Adjust the power-supply equipment output to the nominal primary power source level.

Apply the 1 kHz sinusoidal signal to the input of the specimen and adjust the gain of the system until the rated r.m.s. output power is achieved.

Maintain this gain for 1 min.

17.4.2.5 Final measurements

After 1 h recovery time at standard atmospheric conditions, measure the frequency response of the specimen in accordance with 17.6 or 17.7, as applicable.

Compliance
