Example of RK90R connection with a control unit. In this case, the detector occupy a control equipmet
zone.
In this case the detector is a zone of the system.
The state of the indicated relays correspond to the normal operation condition of the detector.
The Alarm output is the one of the Alarm relay (circuit sensible to Obscuration circuit) or the one from
the Turbulence relay (circuit sensible to Turbulence (heat) circuit).
The Turbulence relay, if not necessary, can be left unused.
The Fault output is the one from the NC contact of the Fault relay of RK90R.
The values of the resistances of Alarm and End of Line will be indicated by the control unit manufacturer.
