Nittan (ST-H-AS) Analogue Addressable Heat Detector
Unlike smoke detectors that detect the presence of smoke particles, heat detectors only react to changes in temperature. The ST-H-AS is a Thermistor based Heat Detector, which uses electronic components that change their resistance when heated; this change is detected by circuitry within the detector.
The ST-H-AS is an attractively-styled, low cost, low profile heat sensor for use with Nittan 'AS' protocol control panels. This sensor is identical in function to our TCA-AS/TCA-AS2LR sensor and can therefore be used as a direct replacement.
