Deployment Considerations
MS8250 Room Controller placement must be given careful consideration. It is recommended to install the MS8250 Room Controller as close
to a door as possible (but not so as to be blocked by the door), or in an area with high occupant movement.
Ideally the Room Controller should be installed four to five (4 to 5) feet (1.2 to 1.5m) above the floor to ensure maximum detection range is
achieved. As well, MS8250 Room Controller placement should ensure the occupant crosses the lens beam in a perpendicular path within the
prescribed detection zone.
Example of Recommended Deployment
The below shows Room Controllers installed in ideal
locations for two rooms.
The examination room shows one Room Controller
installed adjacent to the door. In this area of the room,
occupant traffic is high and ensures the occupant
will almost always cross the Passive Infrared Sensor
(PIR) detection path laterally and within the detection
range.
The waiting room shows one Room Controller
installed beside a door in the middle of the room. As
shown in the diagram below, occupant traffic is high
in several areas of the room including the entrance,
waiting room, access to the door and activity around
the reception desk. Moreover, for each case afore-
mentioned, occupant movement almost always moves
lateral to the PIR, which ensures detection by the
PIR, as well as respecting the PIR detection range
of 20 feet (6 meters) at 140°, and 16 feet (5 meters)
between 15° to 30° laterally.
DEPLOYMENT CONSIDERATIONS
Figure 15: Recommended Deployment for the MS8250.
Example of Incorrect Deployment
The image below shows four MS8250 Room Control-
lers (two for each room) installed in non-ideal loca-
tions for the two rooms.
The examination room shows one MS8250 Room
Controller installed in a low traffic area near the door,
and a second MS8250 Room Controller installed on
the wall directly opposite the door. For the MS8250
Room Controller installed in the corner wall, the PIR
could be blocked by the opened door, while occupant
traffic cold also be minimal in this area of the room.
For the second MS8250 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 be not be lateral to the PIR, thereby not respecting
optimal crossing patterns for PIR detection.
The waiting room shows one MS8250 Room Controller installed in the corner of the room, and a second MS8250 Room Controller installed
beside the reception area. For the MS8250 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 MS8250 Room Controller installed beside the recep-
tion area, occupant traffic could fall outside the detection zone, and the receptionist would often be below the four to five (4 to 5) feet (1.2 to
1.5m) recommended installation height for the MS8250 Room Controller.
