Description
The KI-OSHD Optical (Photoelectric) Sensor provides advanced detection and a practical design that increases efficiency, saves installation time, reduces costs, and extends life and property safety. Long-term reliability, while environmental compensation helps reduce maintenance costs. The KI-OSHD provides an optical smoke detector with a fixed rate-of-rise temperature sensor. These two sensors efficiently detect smoldering fires as well as fast-flaming fires. Like all Kidde optical devices, the KI-OSHD collects analog information from its sensing elements and converts this data into digital signals. To make an alarm decision, the detector’s onboard microprocessor measures and analyzes smoke and heat sensor readings and compares this information to historical data. Digital filters remove signal patterns that are not typical of fires, virtually eliminating unwanted alarms.
Detection and reporting technology: Each detector's microprocessor provides additional benefits of self-diagnosis and log history, automatic device assignment, and fast, stable communication.
Self-diagnosis and history record: Each KI Series detector constantly runs self-tests to provide important maintenance information. Self-test results are automatically updated and permanently stored in the detector's non-volatile memory.
Automatic device mapping: The loop controller learns where the serial number address of each device is installed relative to other devices on the loop. The mapping feature provides oversight of each device's installed location to prevent a detector from being reinstalled (after cleaning, etc.) in a different location than where it was originally installed.
Fast and stable communication: Onboard intelligence means less information needs to be sent between the detector and the loop controller. Apart from the regular response to supervisory polls, the detector only needs to communicate with the loop controller when it has something new to report.
