Circuits and Zones
Circuit = this refers to an actual electrical interface, initiating (detection), indicating (signal), or relay.
Zone = this is a logical concept for a fire alarm protected area, and will consist of at least one circuit.
The terms zone and circuit are used interchangeably throughout this manual.
On the Smart Connect Multi-loop, circuits can be either conventional or addressable inputs or outputs. Both hardwired conventional
inputs and outputs, and addressable inputs and outputs may be grouped together to form logical zones.
Wiring Styles
Loop Circuits
have a redundant pathway (powered from both sides of the circuit) and are able to be wired either in the Class A
designation or in the Class X designation (designed to operate past any a single short circuit with the addition of EN54 listed isolators).
Conventional Zone Circuits
do not have a redundant path. The SCM-ZMM has 6 Class B circuits and simply terminates at the last
device.
Alarm Circuits
do not have a redundant path. The SCM-ACM has 2 Class B circuits and simply terminates at the last device.
