5.1.6 Provisions for tests
5.1.6.1 The following shall be provided for testing compliance with this part of ISO 7240:
a) for manual call points that are simple switches or contain simple electronic components:
— 8 specimens for indoor use, or
— 10 specimens for outdoor use;
b) for manual call points with active electronic components:
— 13 specimens for indoor use, or
— 15 specimens for outdoor use;
c) 30 additional frangible elements if replacement of the element to reset the manual call point is necessary; d) technical data sheets or specifications in accordance with 4.2.2;
e) additional technical information, if required, e.g. diagrams, design drawings with dimensions, parts lists and material data.
5.1.6.2 The specimens submitted shall be representative of the manufacturer’s normal production with regard to their construction and settings.
5.1.7 Test schedule
5.1.7.1 Number the specimens randomly with the following specifications:
a) 1 to 8, if 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, 14 and 15 if they are for outdoor use and are simple switches or contain simple electronic components;
d) I to 15, if they are for outdoor use and contain active electronic components.
5.1.7.2 Record any change in the number and numbering of specimens, e.g. in line with in Table 1, in the test report accordingly.
5.1.7.3 All specimens shall be initially tested in accordance with the test facility test of 5.4 and then be tested in accordance with Table 1.
5.4.3.2 No fault signal shall be given during the test.
5.4.3.3 When reset in accordance with the manufacturer’s instructions, the specimen shall return to its
normal condition.
5.5 Reliability (endurance)
5.5.1 Object of test
The object of the test is to demonstrate the reliability of the operating element.
5.5.2 Test procedure
5.5.2.1 Test apparatus
Use a suitable method of activating and resetting the operating element, which for type A simulates the alarm condition of the frangible element, followed by the resetting to its normal condition, and for type B activates and resets the operating element with the frangible element removed.
NOTE If suitable, the test facility of 4.6 can be used for this test.
5.5.2.2 State of the specimen during conditioning
Mount the specimen in accordance with 5.1.3 and connect it to suitable supply and monitoring equipment as described in 5.1.2. Adjust the supply parameters within the manufacturer’s specifications for conditions most likely to cause failure.
5.5.2.3 Conditioning
Activate and reset the operating element 250 times.
5.5.2.4 Final measurements
5.5.2.4.1 Visually inspect the specimen for any damage.
5.5.2.4.2 Test the specimen as described in the operational performance test of 5.2.
5.5.3 Requirements
5.5.3.1 There shall be no visible damage to the specimen likely to impair its operation.
5.5.3.2 In the test of 5.5.2.4.2, the specimen shall comply with the requirements of 5.2.3.
5.6 Variation of supply parameters
5.6.1 Object of test
The object of the test is to demonstrate that within the specified range(s) of the supply parameters (e.g. voltage), the ability of the device to signal an alarm is not unduly dependent on the supply parameters.
5.6.2 Test procedure
5.6.2.1 State of the specimen during conditioning
Connect the specimen to suitable supply and monitoring equipment as described in 5.1.2.
