Product Information

The Signature Series SIGA-PDI optical smoke detector brings advanced sensing technology to a practical design that increases efficiency, saves installation time, cuts costs, and extends life safety and property protection capabilities. Continuous self-diagnostics ensure reliability over the long-haul, while environmental compensation helps reduce maintenance costs.

Like all Signature Series detectors, the SIGA-PDI is an intelligent device that gathers analogue information from its optical sensor, converting this data into digital signals. To make an alarm decision, the detector’s on-board microprocessor measures and analyses sensor readings and compares this information to historical data.

Digital filters remove signal patterns that are not typical of fires, thus virtually eliminating unwanted alarms.
