Clause / Requirement Compliance Signature
17 Tests All tests as asked for in the clauses of section 17 have been
carried out by an accredited certification body for ISO7240-16
compliancy.
The Praesideo system has been found compliant to ISO7240-
16 and received a certification of compliancy.
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.
Praesideo does not support the optional function disabled
condition. See 9.
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
17.4.2.2 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 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.
