APPENDIX A. TERMINAL CORRESPONDENCE
The terminals of a VT8650 are identied differently and have a wider range of possible functions compared to those of any of the
VT7000 Room Controllers. Nonetheless, there is a direct correspondence of functions between the terminals of the VT7000 and
the VT8650. Consult the table below to verify the appropriate terminal when replacing a VT7000 Room Controller with a VT8650
Room Controller.

APPENDIX B. POWER OUTAGE CLOCK RESET
In the event of a power outage, Room Controllers retain the correct time as long as the duration of the power outage is not
prolonged. Depending on the duration of the power outage, the Room Controllers internal clock may need to be updated or reset
completely. The following table gives an indication of the expected clock performance after a power outage of a given duration.
Outage duration Room Controller behavior
0 - 24 hours Clock functions are normal
24 - 36 hours Clock accuracy not guaranteed, time may need to be adjusted
36 - 72 hours Clock no longer increments and must be adjusted when power is
restored.
72+ hours Clock functions are fully reset, and must be reinitialized as per a new
installation.

14 VT8650 [ Installation Guide ]
APPENDIX C. DEPLOYMENT
Placement of the Room Controller must be given consideration. It is recommended to install the 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 5 feet (1.5 meters) above the floor surface to ensure maximum detection range is
achieved. As well, Room Controller placement should ensure the occupant crosses the lens beam in a perpendicular path within
the prescribed detection zone.
C.1 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 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 aforementioned, 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.
Recommended Installation

15
VT8650 [ Installation Guide ]
C.2 EXAMPLE OF NON-RECOMMENDED DEPLOYMENT
The 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 cold 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 be not be lateral to the PIR, thereby not respecting optimal crossing patterns for PIR detection.
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 foot recommended
installation height for the Room Controller.
Non-Recommended Installation

C.3 ROOM CONTROLLER PIR SENSOR DETAILS
The internal Room Controller PIR sensor only detect lateral movement. It cannot detect movement when a person is moving
toward it. It will not detect someone seating on a chair and/or lying on the bed.

C.4 RECOMMENDATIONS FOR INSTALLATIONS
1. Install the Room Controller to cover more lateral movement.
2. Install a door sensor, the internal Room Controller occupancy logic works better with a door sensor. Once a motion is
detected after a door is opened, the room stays in occupied state until the door is opened again which put the Room
Controller in stand-by mode and if there is a motion then it goes back in occupied mode. It is also recommended to
disable the unoccupied mode, set the unoccupied time to 0, so there is only 2 modes in the Room Controller: stand-by and
occupied for a stand-alone solution. Please refer to the two(2) diagrams below for the Room Controller internal occupancy
states transition.
