34、 the measurement and tests laboratory shall be those specified in EN 60068-1:1994, 5.3.1, unless stated otherwise. Temperature 15 C to 35 C Relative humidity 25 % RH to 75 % RH Air pressure 86 kPa to 106 kPa Noise level Shall not exceed 65 dB C-weighted (alternatively 70 dB linear) in the frequency

35、range of 12,5 kHz to 16 kHz; time averaging has to be set to fast (0,125 s) when measuring 6.2.2 General detection testing environment and procedures 6.2.2.1 General Manufacturers documented instructions regarding mounting and operation shall be read and applied to all tests. 6.2.2.2 Testing environ

36、ment For passive acoustic glass break detectors, the detection tests require an enclosed, unobstructed and draught-free area having a length at least 25 % larger in the long dimension and at least half of long dimension length in the short dimension than the manufacturers claimed range. See Annex A

37、for a description of a potential test room. The minimum sized standardized glass types (glass window or door glass pane as defined in Annex B) needs to be in a fixed off centre position in both directions (horizontal and vertical) in a fixed solid wall e.g. brick, block or concrete. The fixed off ce

38、ntre means the mounting position of the window, whereas the minimum distance of the window centre is between 28 % and 37 % of the length of the mounted wall from either side of the wall. The detectors shall be mounted in the as-used position on a wall, or ceiling at the height specified by the manuf

39、acturer. Testing the maximum detection range of a passive acoustic glass break detector can be performed by installing a detector in the maximum distance position on a wall or ceiling, whereas the maximum distance will be measured as in the corresponding test section described. Alternatively to the

40、wall or ceiling, it can be installed on a free standing rig, whereas the installation position has to be in the horizontal centre of a 1,20 m wide, 2,40 m high and 18 mm thick laminated wooden plate. The free standing rig has to be setup in opposite and parallel position to the monitored object. Tes

41、ting the minimum detection range of a passive acoustic glass break detector can be performed by installing a detector in the minimum distance position on a wall, ceiling or close by the monitored object, whereas the minimum distance will be measured as in the corresponding test section described. Th

42、e test room shall comply with the RT60 definition.

43、st procedures The tests will be performed with the types of glass claimed by the manufacturer. These tests will be performed with the sizes and thicknesses of glass specified in Annex B. Additionally, tests will be performed with the minimum size claimed by the manufacturer, if it is smaller than th

44、e minimum size specified in Annex B. Additionally, tests will be performed with the thinnest glass claimed by the manufacturer, if it is thinner than the minimum thickness specified in Annex B. The detector shall be connected to the nominal supply voltage and connected to the monitoring system that

45、is appropriate to the test. The detector shall be allowed to stabilise for 180 s. The intrusion signal or message output shall be monitored. If multiple sensitivity modes are available, any non-compliant modes shall be identified by the manufacturer. All compliant modes shall be tested. 6.3 Basic De

46、tection Test 6.3.1 General The purpose of the Basic Detection Test is to verify that a detector is still operational after a test or tests has/have been carried out. The basic detection verifies only the qualitative performance of the detector. The Basic Detection Test is performed using the BTS. 6.

47、3.2 Basic Test Source For functional verification there shall be a device available which will simulate a glass breakage or destruction, without breaking the glass (BTS), alternatively a pane of standard sized glass (see Annex B) can be broken to verify the detection. The Basic Test Source (BTS) whi

48、ch is specified by the manufacturer simulates the breaking of a standard glass window by the low energy attack test. The available test device shall be based on recorded glass break sounds, from or recommended by the manufacturer. This device should be a glass break simulator which ensures reliable locating and
