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 SIGA-OSHD provides an optical smoke sensor and a rate-of-rise heat sensor with a fixed temperature setting. Together these sensors efficiently detect smoldering fires,

Audible Sounder Base, low frequency (520Hz), Mounts to 4” square (2-1/8 inch deep).

The SIGA-OSHD provides an optical smoke sensor and a rate-of-rise heat sensor with a fixed temperature setting. Together these sensors efficiently detect smoldering fires, as well as fast flaming fires.

The SIGA-OSCD provides a combination of optical detection for the early detection of smoke, with the added element of carbon monoxide sensing. The result is a detector that pulls double duty: continually monitoring the environment for signs of fire, as well as its invisible yet deadly companion, carbon monoxide.
