Nittan Heat Analogue Sensor (ST-H-AS Replacement)

The Nittan ST-H2-AS is a thermistor-based analogue addressable heat sensor that reacts quickly and reliably to rising heat levels.

As a direct replacement for the ST-H-AS model, the ST-H2-AS incorporates advanced sensing technology with robust, fully modulated AS communications protocol for dependable performance. Its thermistor element changes resistance when heated, with the detector’s internal circuitry processing the signal to trigger an alarm condition.

Supplied with EEPROM addressing capability, the sensor requires the MTM Address Programmer for setup, ensuring secure and accurate system integration.
