Product Overview:
OT8023 Addressable Smoke&Heat Combination Detector is designed with a unique optical sensing chamber designed to sense smoke particles produced by a wide range of combustion sources, and a precise NTC resistor which can sense the environment temperature and initiates an alarm in response to rapid rate-of-rise condition (A2) or a fixed temperature.
It has automatic compensation for sensor contamination and complete self-diagnosis that can greatly reduce false alarm.
