Description

Zone Expansion: Adds up to eight Class B hardwired zones. Connectivity: Connects to the main control panel via a four-wire addressable ECP (Enhanced Communications Protocol) bus. Resistors: Uses end-of-line (EOL) resistors (typically 1K or 2K ohm, depending on the specific version) to supervise for open, shorted, and normal circuit conditions. Addressing: Features simple DIP switches for addressing the module, which determines the starting zone numbers in the system. Installation: Can be mounted inside the control panel's cabinet or remotely on a wall, with provisions for tamper protection if mounted remotely.
