Stock Commonly Controlled

        iSeries Controller

        All Gallagher iSeries chargers come with a controller device (fully waterproof) which can be placed strategically in high-traffic areas (even outside) up to 164' from your energizer. The controller shows current performance readings on your fence line including voltage and amperage in numeric digital displays. (Included with every iSeries charger)

        Alarm Functionality

        All Gallagher iSeries chargers are compatible with the iSeries alarm component which allows for integration of various visual or auditory alarm systems (flashing lights, sirens, etc.). Perfect for use in protecting valuable farm equipment. (Sold individually)

        SMS Alert Functionality

        Using the iSeries SMS controller you can bring out even more flexible functionality in your iSeries charger. Receive all performance info straight to you cell phone through SMS text, get text alerts when a fault is picked up on your fence line, and even turn your energizer on and off through texts. (Sold individually)

        Multiple Zone Control & Alerts

        Both the M1800i and the M2800i are compatible with the fence monitors required for zone control. Zone control requires the use of fence monitors placed at locations along your fence line dividing it into "zones" which can be monitored separately. (ex. you would receive alerts that "zone 2" has a fault as opposed to simply "there is a fault in your fence line").

        iSeries Remote & Fault Finder

        The M2800i is compatible with the iSeries remote which allows you remote access to all fence zones' performance levels as well as remote access to turning ON/OFF your entire fence line or just specific zones.

        The iSeries remote also has all the functionality of your basic digital volt meter/fault finder.
