Axis AU LogoClass A1R & B Heat Detector

VEGA detectors communicate on 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. 

The detector employs powerful algorithms to analyze the status of the protected area whilst guaranteeing a high rejection to false and unwanted alarms. 

The V350 thermal detector can be configured via the control panel to be an EN54-5 A1R or EN54-5BS operating device. 

A unique range of Decorline finishes are available.
