PW-300STA intelligent point type smoke/heat multisensor detector contains an optical smoke sensor and a thermistor temperature sensor whose outputs are combined to give the final analogue value.
The way in which the signals from the two sensors are combined depends on the response mode selected. The different modes provide response behavior which incorporates pure heat detection, pure smoke detection and a combination of both. The multisensor detector is therefore useful over the widest ranges of applications.
