About this item
How does A2S differ from A2R?
A2S is a fixed threshold, A2R is rate of rise. Both are EN 54-5 classes, switched from the C-NET panel.
What is in the box?
The head and a dust cap. Order the base separately. Quiescent current is about 200 µA, and the EN 54-17 isolator is already in the detector.
