GB continuity

The GB continuity line allows a mixture of MCPs and detectors within the same zone.
In addition this mode supports a reliable operation, even though one or more detectors
are removed from its base. The CIE detect the removed detector and report a zone fault.
Technical:
- Special detector bases equipped with a diode (1N5819):
DB110D part number S54372-F6-A1 or DB110RD part number S54372-F8-A1
- MCPs require a Z-diode for direct alarming (AVC).
- Siemens detectors 110-series or detectors with an alarm resistor are required for
delayed alarming (AVC, V1 / V2).
- Each line must be terminated with EOL element Capacitor 10 µF.
- Limitation: Max. 18 detectors per line is allowed due to voltage drop on the detector
base.
- MCPs have no limitation and can be installed to reach the maximum of 32 devices.
