SIGA-PS INTELLIGENT PHOTOELECTRIC SMOKE DETECTOR The Intelligent Photoelectric Smoke Detector (SIGA-PS) is a component of the Signature Series. This intelligent analog devise uses an optical sensing chamber to detect smoke. The detector analyzes the sensor data to determine when an alarm is initiated. The detector continuously monitors changes in sensitivity due to the environment (e.g. dirt, smoke, temperature, humidity) and notifies the loop controller of it's condition. The SIGA-PS issues a dirty sensor warning when it reaches its preset limit. This notifies the operator of the need for service while the detector is still operating within UL/ULC limits. LEDs: The SIGA-PS provides two LEDs that show it's status" Standalone alarm: both LEDs glow continuously Electronic addressing: The loop controller automatically assigns addresses to the detectors. Custom addresses can be assigned to the detectors via laptop computer. No addressing switches are used. Standalone operation: If unable to communicate with the loop controller, the detector alarms when smoke levels exceed its preset value. Refer to the applicable fire alarm control panel manual for verification of standalone capabilities. Self-diagnostics: The SIGA-PS contains a mictoprocessor capable of performing comprehensive self-diagnostics and storing the results. Details such as hours of operation, last maintenance date, sensitivity values, and number of alarms and troubles are stored in non-volatile memory. These can be retrieved and reviewed as desired.
