Edwards EST IO64-RE (Replacement Electronics Assembly, Main Board)

The Edwards EST IO64-RE is the replacement electronics assembly for IO64-series fire-alarm control panels. It replaces the main control board and restores native capacity of one Class B or Class A Signature loop supporting up to 64 addressable devices, along with two Class B notification-appliance circuits rated up to 2.5 A each for system signaling. When installed in the existing cabinet with the panel’s power supply and display assembly, the board retains Genesis strobe synchronization with horn-silence capability, selectable Temporal 3 and Temporal 4 coding, two programmable front-panel switches with LEDs, and Form C alarm and trouble relays. Communicator not included; optional SA-DACT provides Contact ID reporting.
