Interlogix 120-3648 8 Input/2 Transistor Output PCB only

The Interlogix 120-3648 is an 8 input and 2 transistor output PCB designed for expanding security systems. It connects via the SNAPP bus, allowing you to add multiple detection devices without rewiring back to the main control panel. This module supports various input circuit types to fit different installation needs.

Using RS485 communication, the board supports cable runs up to 2000 feet (610 meters). Its distributed processing technology streamlines system expansion while keeping costs down compared to full system replacement.
