The ETC EOCC is a large room occupancy sensor designed for facilities that need dependable automatic lighting shutoff in spaces that are frequently left unoccupied. Built for Echo systems, it uses passive infrared sensing and a 360-degree coverage pattern to support occupancy-based lighting control in applications such as conference rooms, offices, education spaces, hospitality venues, healthcare facilities, retail environments, and houses of worship.

This model connects to the EchoConnect two-wire, topology-free bus for both power and communication, eliminating the need for an additional power pack. Integrators can use configurable coverage masks to refine the sensing area, while walk-thru mode and lens illumination help verify placement and operation during setup. The EOCC supports configurable auto-on/auto-off occupancy sensing functions and is intended for projects where broad room coverage and streamlined installation are important.
