It is important to solder/tin electrical loop connections to prevent oxidization. Tinning your connections might seem like a hassle, especially if you aren’t aware that portable butane powered soldering irons exist.
Tinning the loop connections is a must with inductance loops, wire nuts are just not enough. Often installers will use wire nuts to connect the two wires together. The problem with this is that wire nuts are made for 110-220 volt circuits. Most loop detectors energize the loop with only 3-6 volts. At this low voltage any oxidization of the wire joint can cause enough resistance to cause the detector to have false trips or to lock up.
To save on repeat service calls soldering the connections is a must. Having to go out to a jobsite that is experiencing intermittent loop problems just because the wires are not making a solid electrical connection is a waste of time. This is an issue that many installers will not diagnose correctly when troubleshooting and will often end up replacing perfectly good detectors or loops.
Save yourself the headache and solder/tin your connections.
