AS 7240.22:2018 Fire detection and alarm systems
5.1.2  Mounting arrangements Mount the specimen 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 least favourable shall be chosen for each test.
5.1.3  Operating conditions for tests
5.1.3.1 If a test method requires a specimen to be operational, then the specimen shall be connected to suitable supply and monitoring equipment with characteristics as required by the manufacturer’s data. Unless otherwise specified in the test method, the supply parameters applied to the specimen shall be set within the manufacturer’s specified range(s) and shall remain substantially constant throughout the tests. The value chosen for each parameter shall normally be the nominal value or the mean of the specified range. If a test procedure requires a specimen to be monitored to detect any alarm or fault signals, then connections shall be made to any necessary ancillary devices (e.g. through wiring to an end- of-line device for collective detectors) to allow a fault signal to be recognized.
5.12.2.1  Apparatus The test apparatus (specified in Annex E) shall consist of a swinging hammer incorporating a rectangular-section aluminium alloy head (aluminium alloy Al Cu 4 SiMg complying with ISO 209, solution- and precipitation-treated condition) with the plane-impact face chamfered to an angle of 60° to the horizontal when in the striking position (i.e. when the hammer shaft is vertical). The hammer head shall be (50 ± 2,5) mm high, (76 ± 3,8) mm wide and (80 ± 4) mm long at mid-height.
5.12.2.2  State of specimen during conditioning Mount the specimen rigidly to the apparatus by its normal mounting means and position it so that the portion of the SDED that is not mounted within the duct (e.g. the detector housing) is struck by the upper half of the impact face when the hammer is in the vertical position (i.e. when the hammerhead is moving horizontally). Choose the azimuthal direction and the position of impact relative to the specimen as that most likely to impair the normal functioning of the specimen. Connect the specimen to its supply and monitoring equipment as specified in 5.1.3.
