13.1.4 Sensor loops overview and wiring
The resistance on the loop sets the number of normally-open or normally-closed detection
devices each sensor loop can supervise. Resistance on each sensor loop must be less than
100 Ω with the detection devices connected.
The module detects circuit conditions on its sensor loops and sends the conditions to the
control panel. Each sensor loop has an assigned point number.
Use twisted-pair wire for the module sensor loops to avoid electromagnetic interference
problems. Run wires away from the premises telephone and AC wiring.
Sensor loop terminals are labeled 1 through 8. Terminals 1 and 2, 3 and 4, 5 and 6, and 7 and
8 share common terminals. The common terminals for each pair are labeled COM.
You can configure each sensor loop for a single EOL resistor, or for dual EOL resistors. Single
EOL resistor is the default. For dual EOL resistors, set the Point Profile > Circuit Style
parameter to dual.
Notice!
You do not need to install the EOL resistor for unused points (Point Profile parameter set to 0
[zero]).
UL does not permit normally closed loops for commercial fire applications.
Notice!
Optionally use these points for household fire applications. You can connect four-wire
detectors to these points, for example.
