Panasonic Electric Works Nordic ABMEW01351 Rev: - Planning Instructions Fire alarm system EBL512 G3, V1.1.x14824 Current consumptionThe different loop units have different current consumption. Note thatsome units have much higher current consumption in "active state".To check the current consumption on the COM loops, cable lengths,etc. the tables below can be used. See also dwg. 512-41 and chapter"COM loop cable length", page 145. Also, to get a total currentconsumption overview and to check if the battery capacity is enough,the tables below can be used.The current consumption is normally shown at nominal voltage (24 VDC), in Normal state (quiescent) and in Alarm state (active). Bybattery back-up (i.e. no mains) the voltage can be 27 – 21 V DC.See also chapter "Power supply", page 152.C.i.e. units Normal state(quiescent) (mA)Alarm state(active) (mA)Control unit 5000 (without printer) 126 230 290Control unit 5000 (with printer) 126 253 312127Control unit 5001 ("grey box without front, printer, etc.) 126 179 214Printer in 5000 23 3508 zones expansion board 4580 15128 151298 relays expansion board 4581 15 15In & outputs expansion board 4583, no units connected 15 15TLON connection board 1590 approx. 5 approx. 5Web-server II 1598 60 65The control unit values above are measured during battery back-up(i.e. no mains).126 Control unit – backup battery powered. COM loops and ext. equipmentcurrent consumption not included.127 When the printer is active the current consumption is 667 mAmomentarily.128 Add 0.5 mA per input (zone) for end-of-line capacitor (470 nF) and 3 mAper input for end-of-line resistor (10K).129 Add 30 mA per input (zone) activated. (Each input has a 30 mA currentlimitation, i.e. also for short-circuit on the line.)
