1.10 Eliminating the reasons for the alarmÇ Sabotage at the control unit, terminal or operator terminalCheck whether the lids of all devices are properly closed, i.e. whether the top is correctly latched into place and alsoscrewed to the internal housing.È Door sabotage (*)Check the door and correct installation of the door / monitoring contact. If the door has not been sabotaged, it maybe necessary to enlarge the latch bolt throw of the mating part slightly in the emergency exit strike.É Ê Emergency openTo reset the emergency switch, the cowling must be removed. In the terminal module, it is released from itsanchorage by turning the key-operated switch as far as the second stop in the counter clockwise direction.The panic button of the emergency switch is also simply pulled out in the door terminal. In the terminal module, itmust be reset by a slight turn to the left or right. After this, the required switching status can be restored using thekey-operated switch.In the terminal module, when the emergency switch cap is set for destructive operation, before replacing thecowling, the cap must be renewed (see page 8).Ë Ì Central emergency openInitially, the central emergency open switch must be reset. After resetting, the individual doors must be switchedback to the required status.Í No locked status acknowledgementThis message can occur, for example, if the door has not been fully closed, so that in the case of surface holdingmagnets the counter holding plate is not making contact with the pole surface or the emergency exit strike is unableto lock because a strong door seal is pressing slightly onto its latch bolt. Ensure that the door is able to closeproperly. (It may be necessary to reset the door shutter). In the case of surface holding magnets, no externalparticles may be permitted to prevent the surface holding magnet from making flush contact with the pole surface.Î External emergency unlocking. (Fire alarm systems)After acknowledging the alarm initially the external contact must be reset (closed again). After this, the requiredswitching status can be restored again at the control terminal.Ï Smoke detector lineWhen a smoke detector has triggered, turn the key-operated switch of the terminal momentarily to the left twice.After the second momentary contact pulse, the alarm is reset after around 7 seconds and the detector loopreactivated. (Provided there is no further evidence of smoke at the detector).Please note that most alarm signals can be triggered also by a line interruption - for example a cablebreakage. If a check and remedy of the above listed criteria fail to reverse the alarm status, have theinstallation checked by a specialist!58
