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.

Contact coupler SPF 5300
The contact coupler SPF 5300 is a multiple input module and is used for recording up to four
items of information or comm
with contacts, e.g. from announcement systems, sprinkler systems, technical alarms, techni-
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 a
dvantage of this element is that power is supplied to the element from the loop so t
n
o external PSU i
supply is not available for contacts with LED
Every input can be separately addressed, including as a detector zone.
UP to 128 contact coupler modules may be
coupler module occupies one address in the SIGMALOOP. Contact typ
be connected: Gold, Reed or equivalent.
Elements fed by the MPL may not be connected.
The inputs are to be programmed in strict c
Line connection
The contact coupler module can connect four lines.
The maximum length of all contact lines is 40 metres.
