MEC-P20EP 20-ZONE EMERGENCY ALARM MONITOR EXPANSION PANEL

MEC-P20EP ABS EXPANSION PANEL

The MEC-P20EP Expansion Panel is designed to work in conjunction with the MEC-P20MS or MEC-P20MP main control units, extending the system’s alarm monitoring capability. Each module provides real-time status display for up to 20 zones, and when connected via RS-485 communication, up to four expansion panels can be cascaded to achieve a total monitoring capacity of 100 zones, offering a flexible configuration for projects of various scales.

Built with an ABS enclosure, the MEC-P20EP delivers a professional appearance and long-term operational reliability even under demanding environmental conditions. It mirrors the visual alarm indications of the main panel, allowing users to remotely view and monitor zone status across different locations. (Note: Call Accept and Reset functions are available only on the main control panels MEC-P20MS and MEC-P20MP.)
