With reverse polar monitoring a blocking diode is required on each item of equipment with a
terminator resistance of 3k3 at the end of the cable.
The maximum control line resistance is 10% of the equipment resistance, up to a maximum of
150 ohms.

8.2.4 Contact coupler SPF 5300
The contact coupler SPF 5300 is a multiple input module and is used for recording up to four
ands via floating, monitored contacts. The inputs can be seized
with contacts, e.g. from announcement systems, sprinkler systems, technical alarms, techni-
items of information or comm
cal faults, third-party systems, key-operated switches.
The contact coupler cannot be used for automatic detectors which are powered via
the primary line.

The contact coupler module can connect four lines.
The maximum length of all contact lines is 40 metres.
