Edwards EC2-OS

The Edwards EC2-OS is a conventional two-wire photoelectric smoke detector head, part of the EC2 series of interchangeable head-and-base fire detectors. It uses Optica optical sensing technology to detect smoke particles while helping reduce nuisance alarms from non-fire sources such as cooking smoke or water vapor, making it a reliable choice for conventional fire alarm circuits.
