Figure 17: Connecting various types of alarm group and the PROTECTOR Dialer
NB: in the event of an alarm, the alarm group of each detector triggering the alarm must be charged with 1.2 kOhm (alarm resistance). If too many detectors are
connected, the control centre will no longer be able to distinguish between an alarm and a short circuit. For detectors with a very low alarm resistance (e.g. 600 ohm) a
fault can already be triggered if more than one detector in an alarm group is in alarm status. Max. 10 with 1k2
