Panasonic Electric Works Fire & Security Technology Europe ABMEW00748 Rev: 1 Operating Instructions Fire alarm system EBL512 V2.3.x123 Overview3.1 The EBL512 systemEBL512 is a microprocessor controlled intelligent fire alarm system,intended for analog addressable smoke detectors, as well asconventional detectors and manual call points. Programmable controloutputs and output units are available. Up to 512 addresses can beconnected to each control unit (c.i.e.).EBL512 is available in several types, versions and configurations. Itcan be connected to a TLON network, a "system", with up to 30control units. Each control unit has access to all information.EBL512 is designed according to the European standard EN54, part 2and 4. The front conforms with SS3654.3.1.1 Expansion boardsIn the control unit (c.i.e.) it is possible to mount up to six expansionboards. The following types are available:1580 8 zones expansion board1581 8 relays expansion board1582 External FBP interface board 31583 German FBP interface board 41584 Autronica interface board (four BS4 loops)51587 External FBP / DU interface board3Regarding the expansion boards, see also the EBL512 PlanningInstructions and drawings.3.1.2 PrinterControl unit 1549 is equipped with a printer.In control unit 1548 it is possible to mount a 1558 Printer.3.1.3 Power supplyThe main power source is a built-in rectifier (1537), 230 V AC / 24 VDC, 4.5 A.The second power source is a backup battery (2 x 12 V). In the c.i.e.is space for two 24-27 Ah batteries. Larger batteries (up to 60 Ah) hasto be placed outside the c.i.e.The batteries and the rectifier are connected to the Charger board(1657)6, which handles the charging of the batteries, etc. Low or Highcurrent charging mode is selected depending on the wanted backup3 Max. two 1582 + 1587 boards (together) per control unit.4 Max. one 1583 board per control unit. 1583 board is not possible to use inSwedish (SBF) convention.5 Max. four 1584 boards per control unit. 1584 board is only possible to usein Swedish (SBF) convention.6 The former Charger board for EBL512 had the type no. 1557.
