Fact  BD_6 
Information : The fourth floor of Building 32 consists of three sections and shares two staircases, staircase east (SCE) and staircase west (SCW), with other floors of the building, as shown in Figure 1. Each section is divided into some hallway sections (H) and rooms, each of which may be an office (O), a computer lab (CL), a hardware lab (HL), a peripheral room (P), or a meeting room (M). All rooms in a section are accessible via a connected hallway section. There are three hallway sections and 22 rooms to control. Figure 1 shows also the six outdoor light sensors (ols1 - ols6) and the major compass directions. The sensors cover the six directions of the different walls. The label in a room indicates the type of the room and gives a unique number, see Figure 1.

2.1 Office Description

Fact  BD_7 
Information : Each office (shown in Figure 2) has one door (d1) to the hallway section and can have up to two doors (d2, d3) leading to its adjacent rooms. Each door is equipped with a door closed contact, named dcc<n>, where n is the number of the door in the room.
Postreferences : lsref Door : doorClosedContact
    lsref Room : hallwayDoor
    lsref NeighborRoomConnections : neighborDoor
    dkref NeighborRoomConnections : D_NRC1

Fact  BD_8 
Information : Each office is equipped with
1.
one motion detector (imd), so that the room is fully covered.
2.
two ceiling light groups (window and wall). The luminaries in a ceiling light group in any room are turned on or off only as a group.
Each ceiling light group is controlled by one push button on the wall (pb1 and pb2, respectively), which toggles the ceiling light group if pushed.
A ceiling light group in a room shows the following behavior if the corresponding push button is pushed:
(a)
if the ceiling light group is completely on, it will be switched off
(b)
otherwise it will be switched on completely.
3.
Each ceiling light group can be dimmed with its own dimmer-actuator.
4.
two status lines (sll1 and sll2) each of which shows the status of one ceiling light group.

2.2 Computer Lab Description

Fact  BD_9 
Information : Same as office.
Postreferences : lsref Room : md
    lsref Room : hallwayDoor

2.3 Hardware Lab Description

Fact  BD_10 
Information : Same as office, but with more than one door leading to the hallway section.
Postreferences : lsref Room : md
    lsref Room : hallwayDoor

2.4 Meeting Room Description

Fact  BD_11 
Information : Same as office.
Postreferences : lsref Room : md
    lsref Room : hallwayDoor

2.5 Peripheral Room Description

Fact  BD_12 
Information : The peripheral rooms will not be controlled by the control system, and thus they are not described here!

2.6 Hallway Section Description

Fact  BD_13 
Information : Each hallway section is limited by two doors, each of which is leading to an adjacent hallway section or to an adjacent staircase. The associated names of the doors (d1, d2, d3, d4) are shown in Figure 1. Each door is equipped with a door closed contact, named dcc<n>, where n is derived from the label of the door.
Postreferences : lsref DimmableCeilingLightGroup : dimmer
    lsref Door : doorClosedContact
    lsref HallwaySection : eastDoor
    lsref HallwaySection : westDoor

Fact  BD_14 
Information : Each hallway section is equipped with
1.
two motion detectors (imd1 and imd2), placed above the doors at each end of the hallway section to determine the presence of a person near a door,
2.
one motion detector to cover the whole section (imd3),
3.
one hallway section ceiling light group. The luminaries in a hallway section ceiling light group are turned on or off only as a group.
Each ceiling light group is controlled by several push buttons (pb<i>) each of which toggles the ceiling light group if pushed.
A hallway section ceiling light group shows the following behavior if a push button is pushed:
(a)
if the hallway section ceiling light group is on, then it will be switched off
(b)
otherwise it will be switched on
4.
one status line (sll1) that shows the status of the hallway section ceiling light group.

2.7 Staircase Description

Fact  BD_15 
Information : Each staircase connects several floors.

Fact  BD_16 
Information : At the landing of each staircase at each floor, the staircase is equipped with
1.
one motion detector (imd1) above the door of the landing that leads to the adjacent hallway section to detect motion in the staircase near the door.
Postreferences : lsref Staircase : md

2.8 Sensor Description

Fact  BD_17 
Information : Analog sensors typically have an exponential response time. Conversion time is the time to convert the analog value to a digital one that can be accessed by the control system. Reaction time is the time from a change of the sensed property to the time when the sensor has reached 90

2.9 Actuator Description

Fact  BD_18 
Information : Actuators have a linear response time. Reaction time is therefore defined as the time to change from 0 to 100

2.10 Dimmable Light

Fact  BD_19 
Information : The structure of a dimmable light is shown in Figure 3. Inputs to a dimmable light are created by a pulse to toggle the light, by a dimmer to set the current dim value, and by control system active to show the status of the control system. If this signal is not sent every 60 s, the dimmable light switches to fail safe mode, i.e. dim value is assumed to be 100
