Praesideo 3.5 | Installation and User Instructions | ISO7240-16: 2007
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 con-
sidered 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 sub-
jected to the other endurance test. Before and after each environ-
mental 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

17.4.2.2 State 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.
17.4.2.3 Conditioning
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 for-
mation of water droplets on the specimen.
Terminate the s.s.c.i.e. output(s) with the minimum resistive and maxi-
mum capacitive load representing the loudspeaker lines and loud-
speakers.
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.
