| | 8 | -------------------- |
| | 9 | |
| | 10 | Occupancy is monitored in every supervised space (every room) using motion sensors. The control logic |
| | 11 | supports up to four motion sensors per room. The outputs of the sensors are ORed together to create |
| | 12 | the occupied / unoccupied signal for the room. In order to minimize false-negatives, the raw "occupied" |
| | 13 | signal (coming from the sensors) is prolonged to create three logical occupancy signals per room (short, |
| | 14 | medium, and long). The "occupied short" signal, once activated, remains so for at least 10 seconds. |
| | 15 | The "occupied medium" signal, once activated, remains so for at least 15 minutes, and the "occupied long" |
| | 16 | signal remains activated for at least half an hour. Logic blocks can use the short / medium / long |
| | 17 | signals as required. The occupancy signals of several rooms are ORed together to create five aggregate |
| | 18 | occupancy indications: "Front" (for rooms at the front side of the building), "side", "back", "util" (for u |
| | 19 | tility rooms: kitchen, hallways, restrooms, etc), plus a global "building occupied" signal. |
