Description
The Edwards EST 3-IDC 8/4 Initiating Device Circuit Module is a local rail input/output module for the EST3 fire alarm control panel that provides eight supervised Class B traditional initiating device circuits.
The 3-IDC 8/4 is ideal for retrofit projects where existing wiring, smoke detectors and signals may not need replacing.
Flexibility built right into the IDC module allows connection of normally open contact devices, and traditional 2 wire smoke detectors.
