Having a deep base and two terminals per input makes these units convenient for looping to other circuits or for siting ‘end- of-line’ resistors. The base has three knock-outs, two on the side and one on the base, to accommodate PG13.5/20mm conduit or cable glands. The units are polarised and a chain may be fitted with an ‘end-of-line’ resistor for reverse polarity testing and to permit line monitoring. Installation Details Please refer to to EC Type ExaminationCertificate and related System Certificate for full details on suitable interface devices.
