Panasonic Eco Solutions Nordic ABMEW01457 Rev: - Operating Instructions Fire alarm system EBL512, V2.7.x62performed in both directions, to find all the units.It might also be shown after a short circuit on the loop when shortcircuit isolators are used (= communication in both directions).(A double break will give the message: FAULT: No reply …..).It can also be indicating a too long COM loop cable (i.e. all units arenot found until the communication is performed in both directions).NOTE! Communication in both directions lasts for about ten minutes,before a new attempt to communicate in one direction is performed. Ifthe break remains, a new ten minutes period starts, and so on. If thefault is acknowledged and the break is corrected during a ten minutesperiod, it will not disappear from the list until the end of the tenminutes period.FAULT:Cut-off input x,1580 board x,CU xx(8 zones expansion board, DET8)This is indicating a break (cut-off) or a missing end-of-line resistor oninput x (zone line) on the 1580 board placed in control unit xx. (It canalso be a detector that has been removed (stolen) from its base.)NOTE! The input can, as an alternative, be used for a single "slave"unit (control unit) or several control units connected in parallel, i.e. itis used for "Redundancy in distributed system". In such a case theoutput for routing equipment (fire brigade tx) in the "slave" unitrespectively works as a "detector".FAULT: Cut-off loop x, BS4 x, CU xx(1584 Autronica interface board, BS4)Cut-off (break) on the BS4 loop. This is indicating a single break onthe loop. Communication has to be performed in both directions, tofind all units.Each 10th minute is an attempt made to comm. in one direction again.FAULT:Cut-off loop x,CU xx, CU<->ASF0FAULT:Cut-off loop x, CU xx,ASF 0<->ASF 1FAULT:Cut-off loop x, CU xx,ASF 1<->ASF 2FAULT:Cut-off loop x, CU xx,ASF 2<->ASF 3FAULT:Cut-off loop x, CU xx,ASF 3<->ASF 4FAULT:Cut-off loop x, CU xx,ASF 4<->ASF 5FAULT:Cut-off loop x, CU xx,ASF 5<->ASF 6FAULT:Cut-off loop x, CU xx,ASF 6<->ASF 7FAULT:Cut-off loop x, CU xx,ASF 7<->CU
