Signature Series devices are the life safety industry’s first modular detectors. Combining smoke, heat, and carbon monoxide (CO) sensing technologies in a single compact unit, these innovative detectors eliminate the need for separate devices to sense fire and CO. The result is a significant cost and maintenance savings for contractors and building owners alike. Signature Series pushes detection capabilities to the limits of modern technology with proprietary indirect photoelectric sensing technology that provides greater optical stability and a higher degree of reliability.
