Integracja alarmu ruchu CCTV z oświetleniem DALI: Wyzwalacze scen i energooszczędna reakcja

Alarmowa GA → Łańcuch sceny DALI (MDT DALI Gateway)

KNX source:
  GA 8/0/1 (CAM-01 Motion Alarm) = 1 (alarm active)

MDT DALI Gateway SCN-DALI64.01 ETS6 configuration:
  Scene object: "Scene Recall Zone 1"
    Group address: 3/0/10
    DPT: DPT 18.001 (1-byte scene number)
    Scene value to recall: 4 (Scene 4 = Security Alert)

Logic module bridge (MDT SCN-LOGM.01):
  Input A: GA 8/0/1 (motion alarm)
  Input B: GA 8/3/0 (alarm armed status)
  Logic: AND
  Output: GA 3/0/10 (DALI scene recall)
  Output value on TRUE: scene 4 (binary 0b00000100 = DPT 18.001)
  Output value on FALSE: scene 1 (standby, after timer)

DALI Scene 4 definition (programmed in DALI commissioning):
  Zone 1 (Entrance): Level 254 (100%), CCT 4000K
  Zone 2 (Corridor): Level 200 (78%), CCT 4000K
  Zone 3 (Car park): Level 254 (100%), CCT 5700K (daylight)

DALI Scene 1 definition (standby):
  Zone 1 (Entrance): Level 76 (30%), CCT 3000K (warm)
  Zone 2 (Corridor): Level 50 (20%), CCT 3000K
  Zone 3 (Car park): Level 0 (OFF, outside occupied hours)

Trójstanowa logika oświetlenia (moduł logiczny KNX)

State 1 — Occupied (building hours, system disarmed):
  DALI Zone 1: scene 2 (comfort, 80%, 3000K)
  Triggered by: access control entry event or time schedule

State 2 — Armed standby (unoccupied, alarm system armed):
  DALI Zone 1: scene 1 (standby, 30%, 3000K)
  Triggered by: last person exit + 5-minute delay
  Camera IR cut-filter: stays in colour mode (30% ≈ 50 lux)

State 3 — Alarm (motion detected, system armed):
  DALI Zone 1: scene 4 (alarm, 100%, 4000K)
  Triggered by: GA 8/0/x camera motion alarm = 1

Transition State 3 → State 2 (alarm clear sequence):
  On GA 8/0/x = 0 (motion stopped):
    Start 10-minute hold timer
    After 10 minutes: recall DALI scene 1 (standby 30%)
  On GA 8/3/1 = 1 (manual acknowledge):
    Immediate return to scene 1 (override hold timer)

KNX Logic Module SCN-LOGM.01 channel allocation:
  Ch 1: Occupied/Armed state gate (time + access control)
  Ch 2: Alarm trigger (motion AND armed state)
  Ch 3: Return-to-standby timer (10 min staircase)
  Ch 4: Manual acknowledge reset

Wykluczenie opraw awaryjnych ze scen bezpieczeństwa

DALI addressing rules for security lighting integration:

Emergency luminaires (DT-1):
  → Assign to DALI groups 12–15 (dedicated emergency groups)
  → NEVER include in security alarm scene definitions
  → Emergency luminaires respond ONLY to DALI emergency commands
    (Emergency Mode: Test, Inhibit, Reset) from DALI EMS

Non-emergency luminaires (DT-0/DT-8):
  → Assign to DALI groups 0–11 (available for scene control)
  → These are the luminaires included in security alarm scenes

Fire alarm priority override:
  IF fire alarm input (KNX binary input from fire panel) = 1:
    → Recall DALI scene 0 (all non-emergency luminaires OFF)
    → Emergency luminaires activate automatically via DALI EMS
    → Security alarm automation suspended (lower priority)

KNX priority:
  Fire alarm GA (GA 9/0/0) overrides security alarm GA (GA 8/0/x)
  → MDT Logic Module: fire alarm input disables security scene channel

Ustawienia histerezy modułu logicznego

MDT SCN-LOGM.01 ETS6 channel settings:

On-delay (alarm activation):
  Delay: 0 seconds (alarm must respond immediately)
  Rationale: fastest possible lighting response on genuine alarm

Off-delay (alarm clearance / return to standby):
  Delay: 600 seconds (10 minutes)
  Rationale: prevents cycling if motion detection flickers on/off
  Override: manual acknowledge GA 8/3/1 = 1 → immediate clear

Additional cycle prevention:
  Minimum ON time: 60 seconds
  → Once alarm scene activated, hold for minimum 60s
  → Prevents sub-minute cycling from intermittent motion events

Camera sensitivity recommendation:
  Set camera motion sensitivity to medium (40–60%)
  Enable camera-side motion filtering: minimum zone 5%
  Set camera pre-alarm buffer: 3 seconds
  → Reduces false motion events reaching KNX binary input

Test uruchomieniowy krok po kroku

1. Pre-test setup:
   a. Confirm all DALI luminaires commissioned and addressable
   b. ETS6 Group Monitor open — watch GA 8/0/x and GA 3/0/10
   c. Arm system: write 1 to GA 8/3/0

2. DALI scene verification (before camera test):
   a. Manually write scene 1 to GA 3/0/10 (standby)
      → Zone luminaires → 30%, 3000K, confirm with lux meter
   b. Manually write scene 4 to GA 3/0/10 (alarm day)
      → Zone luminaires → 100%, 4000K, measure lux at camera height
      → Minimum 200 lux at 1m above floor for camera colour mode
   c. Manually write scene 5 to GA 3/0/10 (alarm night)
      → Zone luminaires → 100%, 5700K

3. Camera relay trigger test:
   a. Trigger camera motion (walk through detection zone)
   b. Confirm GA 8/0/1 = 1 in Group Monitor within 2 seconds
   c. Confirm DALI alarm scene activates (visible level increase)
   d. Stop motion — confirm GA 8/0/1 = 0
   e. Confirm DALI scene holds for 10-minute timer
   f. Write 1 to GA 8/3/1 (acknowledge) → confirm immediate return to standby

4. Fire alarm priority test:
   a. Set fire alarm GA 9/0/0 = 1 (simulate fire)
   b. Trigger camera motion simultaneously
   c. Confirm: security scene does NOT activate
   d. Confirm: emergency luminaires activate normally
   e. Clear fire GA → confirm system returns to armed standby

5. Disarmed mode test:
   a. Write 0 to GA 8/3/0 (disarm)
   b. Trigger camera motion
   c. Confirm: NO DALI scene change, GA 3/0/10 unchanged
   d. Rearm: write 1 to GA 8/3/0
