Fig. 187
The cable screen is only connected to the SUPREMA.
*1 Connect according to manufacturer´s specification. CERBERUS DO1101EX / DT1101EX:
Document No. e1469. Only the mounting support Order No. 45681-207 specified in the data
sheets must be used. For each detection zone circuit, max. 20 fire detectors are allowed.
Carry out installation according to NFPA 72
*2 End of Line Resistor 2K2 / 0.5 W has to be mounted in the last mounting support of the de-
tection zone circuit or in the portable detector according to the documents specified under *1
*3 Indication of leakage current. In the case of failure, the „OPEN COLLECTOR” transistor is
conducting to terminal 5
