Signature Series SIGA-DSI optical detectors bring 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 highly stable communications means these detectors can be installed on existing wiring for most retrofit installations — no special twisted or shielded cable required. The SIGA-DSI notifies the control panel of changes in sensitivity due to environmental conditions such as dirt, smoke, temperature, and humidity. When it reaches its preset limit, the detector issues a maintenance warning that alerts maintenance personnel of the need for service. The SIGA-DSI remains operational with enough of a safety margin to allow for a service call before performance is affected. This avoids downtime and trouble conditions. Like all Signature Series detectors, the SIGA-DSI is an intelligent device that gathers analog information from its optical smoke sensor, converting this data into digital signals. To make an alarm decision, the detector’s on-board microprocessor measures and analyzes 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.
