Alarm Wire with a DC Barrel Connector Posts

Anyone setting up a new wireless security system will definitely want to consider picking up a Honeywell LT-Cable for their installation. This is a pre-prepared wire that doesn't require any stripping or special tools. All you need is a screwdriver to connect the panel and the transformer.

Alarm wiring is needed to complete the connection between the panel and its plug-in power transformer. Traditionally, users had to strip and prepare their own cabling, which made the process more tedious and difficult. But with prepared cabling like the Honeywell LT-Cable, the process is made much easier, and it really will work with nearly any security system. With this wire, you can install your own security system with just a screwdriver, and without having to hire a professional installer.

There are two (2) parts to the Honeywell LT-Cable. There is a smaller cord that connects with the power terminals on the back of your panel. The other end of this smaller cord has the female barrel connector. Then the larger cord has the male barrel connector on one end and spade connectors for connecting with the plug-in transformer on the other. The larger cord measures eight (8) feet, while the smaller portion is seven (7) inches in length. All together, you get a little bit more than 8.5 feet of wiring with the LT-Cable.

It's surprising to consider that most security systems do not come with a power wire for connecting with a transformer. While the transformer is included, most users can expect to supply their own wiring. A notable exception to this rule is the Qolsys IQ Panel 2 Plus, which does include a power wire. As such, no LT-Cable is needed for an IQ Panel 2, though you might still add one if the original wire ever becomes damaged. But other panels like the Honeywell Lyric Alarm System and the 2GIG GC3e do not come bundled with any cabling, so the Honeywell LT-Cable makes for the perfect accessory.

One other advantage to the LT-Cable is that you can easily unplug the barrel connectors if you ever need to power down your system for adding new hardware or troubleshooting. This can be easier and more convenient than needing to unplug the transformer, especially if the transformer is screwed into the outlet. Remember that you will also need to unplug the system's backup battery to perform a power cycle. If you need a wire run that is longer than 8.5 feet, you might consider purchasing Genesis Alarm Wiring, which is also sold on our site.
