15.7 SUPREMA Sensor Data Sheet Ex-Fire Detector
Apollo Series 60 with Barrier Z 787
Fig. 186
The cable screen is only connected to the SUPREMA.
*1 Connect according to manufacturer´s specification for Apollo Series 60:
SERIES 60 INTRINSICALLY SAFE SYSTEM DRAWING Z209883. Carry out installation ac-
cording to NFPA 72.
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.
*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
