BS EN 54-11:2001 pdf download.Fire detection and firealarm systems —Part 11: Manual call points.
Unless otherwise stated, the tolerances for the environmental test parameters shall be as given In the basic reference standards for the test (e.g the relevant part of IEC 60068).
If a specific tolerance or deviation limit is not spectfled in a reciirement or test procedure, then a deviation lEiiit of ±5% shall be applied.
5.1.5 Measurement of response time
Where the release of an alarm signal in the folowing tests is required, the alarm signal shal be indicated at the supply and monitoring equipment (see 5.1.2) within a response time of lOs after the operating element has been activated.
The response time shall be measured and reported.
5.1.6 ProvIsions for tests
The follaMng shal be provided for tes11g compliance with this European Standard:
a) for manual call points that are simple switches or contain simple electronic components:
—8 specImens for indoor use or
—9 specImens for outdoor use;
b) for manual call points with active electronic components:
— 13 specimens for indoor use: or
— 14 specimens for outdoor use;
C) 30 additional frangible elements if replacement of the element to reset the manual call point is necessary:
d) the technical data sheets or specifications according to 4.2.2:
e) additional technical information, If requwed, e.g. diagrams, design drawings with dimensions, parts lists and material data.
The specanens submitted shall be representative of the manufacturers normal production with regard to their construction and settings.
5.1.7 Test schedule
The speculions shall be randomly numbered:
a) I to 8, ii they are for indoor use and are simple switches or contain simple electronic components;
b) I to 13, If they are for indoor use and contain active electronic components;
C) 1 to 8 and 14, if they are for outdoor use and are simple switches or contain sample electronic components;
d) 1 to 14,11 they are for outdoor use and contaln active electronic components.
Any change in the number and nLsnbering of specimens. e.g. in line with Table 2. shall be recorded in the test report accordingly.
All specimens shall be inttialy tested I, accordance with the test fac*ty test of 5.4 and then be tested ii accordance with Table 2.
5.2.2.1.2 Initial state
At the start of the test the specimen shal be in its normal condition.
52.2.1.3 Conditioning
The frangible element shall be subØcted to a horizontal force increasrig at a rate not exceeding 5 N s until it reaches (22.5* 2,5) N. This force le maintained for 55 then released at a rate not exceeding 5 N srn’. The position where this force shall be subjected is the centre point between the arrows, see Figures 3 C) and 3d).
An example of a suitable test apparatus is shown In annex B.
52.2.1.4 Measurements during testing
The specanen shall be monitored dunng the test period to detect any alarm or fault siglals
52.2.1.5 FInal measurements
a) After the force has been released, the frangible element shall be examined.
b) The specimen shall then be tested as described In the test facility test of 5.4.
522.2 Test for operation
5.2.2.2.1 Conditioning
The frangitle element shal be subjected to a horizontal Impact within 5 mm of the centre point between the arrows, see Figures 3 c) and 3d).
The impact shal be produced by using the test apparatus ii accordance with annex A.
The ball shall strike the specimen once only.
For type B manual call ponts. the operatrig element shal then be manually operated.
52.2.2.2 State of the specimen during test
The specimen shal be mounted on the test apparatus (see annex A) in its normal operating position In accordance with 5.1.3 and connected to a suitable supply and monitoring equipment as descflbed In 5.12.
52.2.2.3 Initial state
At the start of the test the specimen shall be in its normal condition.
52.22.4 ResettIng
After operation, the specimen shall be reset to its normal condition by using the reset facility of 45.
52.2.2.5 Measurements during testing.
