Orbis Detector Bases

There are a number of bases available within the Orbis range of detectors.



Orbis TimeSaver Base

– is the standard base



Orbis TimeSaver LX Base

– incorporates all of the features of the standard Orbis base less

the continuity link



Orbis Diode Base

– used in installations where active End-Of-Line devices are used on the

detector circuits



Orbis Relay Base

– incorporates features of the standard Orbis base with the inclusion of a

relay. This relay is activated when the detector goes into alarm

Orbis detectors and their bases been designed to make installation fast and simple. Figure 4 shows
the TimeSaver mounting base as it is seen from the installer’s point of view.
