Axis En LogoAV Class A1R & B Heat Detector

Axis analogue detectors are designed around a fully digital protocol.

The analogue addressable heat detector incorporates a single, centrally positioned, thermistor which supervises ambient temperature with low thermal inertia, allowing the product to achieve A1R and B classification.

Soft and safe addressing allowing accurate configuration of system installation. 

The unit provides a fast and secure response, and incorporates a bidirectional short circuit isolator. 

A unique range of Decorline finishes are available.
