Fig. 188
The cable screen is only connected to the SUPREMA.
*1 Connect push-button detector according to manufacturer´s specification.
MEDC NG16 6JF Type BGI. WIRING DIAGRAM BGE/I/W + PBE/IW
Contact type: NORMALLY OPEN (terminals 2-3 inside the detector). Carry out installation
according to NFPA72
With resistor 1.8 KW / 0.5 W in series with the contact; max. 10 Pieces
With zener diode 10 V /1.3 W in series with the contact; max. 20 Pieces
Check polarity
*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 in *1
*3 Indication of leakage current. In the case of failure, the „OPEN COLLECTOR” transistor is
conducting to terminal 5
Connection module: MFI (Fire Input Module)
Configuration: External power supply, without Zener barrier.
