AtlasIED IED1516LI-E 16-Input Logic Expansion Module for GLOBALCOM

The IED1516LI-E is designed for system integrators and AV/IT professionals deploying AtlasIED GLOBALCOM mass notification or paging systems who need to expand external trigger capacity beyond the base module's 16 inputs. By connecting directly to the IED1516LI via the included 5-conductor expansion cable, the module brings total input capacity to 32 channels — each capable of accepting dry contact closures or logic signals ranging from 0 to 50VDC — without requiring an additional power feed, since power is sourced through the host module.

In installed audio and life-safety environments, the IED1516LI-E serves as the interface layer between building infrastructure and the GLOBALCOM announcement controller. Typical integration points include fire alarm panels, access control systems, security platforms, and facility automation triggers. Each input is optically isolated, protecting the GLOBALCOM system from ground loops or voltage transients common in mixed-system environments. A dedicated green LED above each input provides real-time visual confirmation of activation status during commissioning and troubleshooting.

Configuration is handled entirely through the GLOBALCOM System Management Center via web browser, where each logic input can be mapped to announcements, pre-recorded messages, scheduled events, or fault reports. Settings are retained in non-volatile memory, ensuring programmed behavior survives power cycles — a critical requirement in life-safety and emergency notification deployments where reliability is non-negotiable.
