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.

EST’s Signature Series Model SIGA-IS Intelligent Ionization Smoke Detector gathers analog information from its smoke sensing element and converts it into digital signals. The detector’s on-board microprocessor measures and analyzes these signals. It compares the information to historical readings and time patterns to make an alarm decision.

The SIGA-270 Fire Alarm Manual Pull Stations feature our very familiar teardrop shape. They are made from die-cast zinc and finished with red epoxy powder-coat paint complemented by aluminum colored stripes and markings.

The EST Signature Series Model SIGA-PS Intelligent Photoelectric Smoke Detector gathers analog information from its smoke sensing element and converts it into digital signals. SIGA-PS on- board microprocessor measures and analyzes these signals. SIGA-PS compares the information to historical readings and time patterns to make an alarm decision.

The SIGA-PD detects extremely small particles of combustion and triggers an alarm at the first sign of smoke. Thanks to its high performance forward-scattering reflective response technology, the photoelectric smoke sensor responds quickly and reliably to a wide range of fire types, espe cially slow burning fires fuelled by combustibles ...
