Edwards EST IO1000-RE (Replacement Electronics Assembly, Main Board)

The Edwards EST IO1000-RE is the replacement electronics assembly for IO1000-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 250 addressable devices (125 detectors and 125 modules), along with four Class B notification-appliance circuits at 2.5 A each for a 6.0 A system total. When installed in the existing cabinet with the panel’s power supply and display assembly, the board retains support for 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. Capacity can expand to 1,000 addresses with optional iO-SDC loop cards. Communicator not included; optional SA-DACT provides Contact ID reporting.
