The 20-AS3500-ADV user programmable rate of rise detector and high temperature detector meets the requirements of EN 54-5 class A1R and class B and provides the highest level of protection when smoke detection is unsuitable.

The thermal detector incorporates a single centrally positioned NTC thermistor that continuously samples temperature variations in the protected area.

Via the VPU100 the 20-AS3500-ADV can be configured as a rate of rise class A1R or high temperature class B thermal detector.

Via the VPU100 the production date of each device can be read.

Note:

The detector base is not included and is available separately.
