Example of Non-Recommended Deployment
The illustration below shows four room controllers (two
for each room) installed in non-ideal locations for the
two rooms.
The examination room shows one room controller
installed in a low traffic area near the door, and a
second room controller installed on the wall directly
opposite the door. For the room controller installed
in the corner wall, the PIR could be blocked by the
opened door, while occupant traffic could also be
minimal in this area of the room. For the second room
controller installed opposite the door, the PIR detection
could fall outside the specified detection zone, while
at the same time most occupant movement would not
be lateral to the PIR, thereby not respecting optimal
crossing patterns for PIR detection.
Non-Recommended Installation
The waiting room shows one room controller installed
in the corner of the room, and a second room controller
installed beside the reception area. For the room
controller installed in the corner, the opening/closing of
the door creates high probability that the PIR would get
blocked, and therefore, occupancy going undetected.
For the room controller installed beside the reception
area, occupant traffic could fall outside the detection
zone, and the receptionist would often be below the
5' recommended installation height for the room
controller.
