Addressable multiplex modules with up to eight sub loops per panel. These units give the System 3505/3500/3000 the ability to monitor addressable devices on a single pair of wires. They support as many as 792 line-powered modules at distances up to 40,000 feet. Features include built-in battery charger, watchdog timer, and Form C output relay controlled from the System 3505/3500/3000. The modules report alarm, trouble, restore, low battery, tamper, AC fail, loop problems, ground fault on the loops and module faults. The DGM-ISO-8L supports addressable devices such as the ISO-6Z. DGM-ISO-8L has an auto configuration mode. After installation, a function may be selected to scan all loops and automatically configure the attached devices.
