38、owing the notification of a false alarm are based on the principle of greater involvement of management, rather than relying on the technical staff alone, at an early stage in false alarm repeat occurrences. In this way, a higher level of technical skills can be directed towards problem installation
39、s to ensure prompt and accurate fault diagnosis, to be followed by the correct remedial solution. H.2Attendance following activation H.2.1 Following the notification of an alarm activation a service technician should attend the premises concerned and should: a)review the event log and ensure that a
40、copy is retained on the clients file by the alarm company; b)determine any previous alarm activations; c)determine the reason for the current alarm activation in accordance with H.2.2, and record the findings; d)carry out repair or remedial work to ensure that a reoccurrence of the alarm activation
41、is unlikely. H.2.2 After the occurrence of a false alarm, inspections and all necessary tests, as appropriate, should be carried out, by the service technician, on the following. a)The operators operational procedure, including securing of supervised premises, setting of the system and whether all p
42、ersons involved with setting and unsetting the system are fully conversant with the procedures. b)The supervised premises, for any change of use or structural changes, electrical supplies or work which could affect the alarm system. c)Any possible sources of environmental interference, e.g. heating
43、systems, automatic lighting control, radio frequency interference and build up of dust and cobwebs, etc. d)The correct operation of the system, in particular: 1)control and indicating equipment; 2)power supplies, including standby batteries and voltages at the detectors and WDs; 3)movement detectors
44、, by walk tests, ensuring that the ranges are properly set and that adverse environmental influences are not inside fields of detection; 4)beam interruption detectors, ensuring that beams are not likely to be obstructed; 5)magnetic contacts, ensuring that supervised doors and windows are physically

H.2.3If the alarm acti
47、vation can be determined to have been an operator error and is likely to reoccur, it might be necessary to adopt another method of unsetting such as the method described in DD 243:2004, 6.4.2.
