• Operation of a high-performance, intrinsically safe
(HIS) ADPRO PIR requires the installation of IS

• The distance from the ADPRO PIR detector to the
non-hazardous area can be up to 200 meters.
• For safe operation according to the certification, it is
necessary to limit all energy over all interfaces to and
from the detector by using barriers:
