This is known as the quie
15、scentcurrent; andb) the current when in alarm with all WDs and ATE activated. This is known asthe alarm current.NOTE 1 The two different readings are required as the standby battery needs to becapable of providing power for the required duration including two periods whenthe system is in a full alar
16、m condition.NOTE 2 Each alarm period can have WDs activated for 15 min.(see BS EN 50131-1:2006+A1:2009, 8.6)C.1.1 Example of time period required in quiescent and alarm conditionIf the required standby period is 12 h, as required at Grade 2, then the batteryneeds to be capable of providing sufficien
17、t power for 11.5 h at the quiescentcurrent +0.5 h (2 15) min at full alarm current.NOTE 1 If the standby period was 24 h then the time periods would be 23.5 hquiescent and 0.5 h in alarm.The battery capacity can then be calculated as follows:C = 1.25 (I1 T1) + (I2 T2)where:C minimum capacity of batt

20、y calculationA Grade 2 intruder alarm system with a quiescent current of 250 mA, alarmcurrent of 750 mA (from above the standby period is 12 h with an assumedperiod of 30 min in alarm condition):Quiescent load =I1T1= 0.25 11.5 = 2.875 AhAlarm load =I2T2= 0.75 0.5 = 0.375 AhC= 1.25 (2.875 + 0.375)C =

22、ion)C.2.2.1 Using a suitable test meter, such as a digital volt meter (DVM), set themeter to read DC Amps (select a high range such as 10 A).C.2.2.2 Disconnect the positive charge lead from the battery terminal (normally apush on receptacle).C.2.2.3 Connect the DVM in series between the positive bat
23、tery terminal and thedisconnected battery lead.C.2.2.4 Disconnect the mains supply to the control panel.C.2.2.5 The total current drawn by all equipment supplied by the control panelPSU is displayed on the DVM.NOTE Typical readings could be between 0.2 A (200 mA) and 0.5 A (500 mA).C.2.3 Alarm curre
24、nt (alarm condition)Repeat the procedure in C.2.2 with the system in full alarm state, e.g. with WDssounding and ATE signalling.NOTE A typical reading could be between 0.4 A (400 mA) 0.7 A (700 mA).BRITISH STANDARD BS 9263:2016 The British Standards Institution 2016 13BibliographyStandards publicati
