Product Overview:
OT603R Addressable Heat (Thermal) Detector is designed to meet the stringent performance requirements of industrial and municipal fire detection/alarm systems.
With a precise NTC resistor which can sense the environment temperature. The detector initiates an alarm in response to both rapid rate-of-rise condition (increases in excess of 6.7°C per minute) and fixed temperature.
It has automatic compensation for excursion and complete self-diagnosis that can greatly reduce false alarm.
