Running Power to a Honeywell L7000

In this video, Jarrett from Alarm Grid shows you how to power on a Honeywell LYNX Touch L7000 System. Like most wireless alarm control panels, the L7000 uses a plug-in transformer for primary power and a plug-in battery for backup power. You must disconnect both the transformer and the backup battery if you want to power the system completely down. This is done when making hardware changes to avoid damage to the panel and the equipment.

When powering down, it doesn't matter whether you unplug the transformer or the backup battery first. But when powering the system back on, it is strongly recommended that you connect the backup battery first, followed by the transformer. Keep in mind that the panel will not power on from battery power alone. It needs the transformer to be connected before it will power back on. This is part of the battery saver circuitry that prevents the panel from discharging the battery too deeply.

The Honeywell L7000 uses a 9VDC, 2.5A transformer for power. This transformer is known as the Honeywell 300-04705. You connect it to the panel using 18-gauge or 22-gauge, 2-conductor wiring. The 18-gauge wire is a bit thicker to allow for longer wire runs, but some users prefer 22-gauge wire due to the fact that it is thinner and more flexible. You can find alarm wire at a hardware store. Another option is to use a Honeywell LT-Cable, which is a prepared cable that doesn't require any stripping. Just keep in mind that the Honeywell LT-Cable is a fixed-length cable, and it cannot be easily extended. As for the backup battery, it has a plug-in connector that secures to a port on the back of the panel. The backup battery will need to be replaced after about four (4) years depending upon use.
