Ajax Hub 2 Plus uzstādīšana: montāža panelī, GSM/Ethernet dublēšana un zonu konfigurācija

Prasības DIN sliedes montāžai

DIN rail adapter (Ajax 99131):
  Occupies: 9 DIN modules (162 mm) on 35 mm rail
  Depth behind rail: 72 mm — verify enclosure depth

Cable entry clearance:
  Bottom: 60 mm free space below hub for Fibra + power cables
  Right side: 30 mm for Ethernet + USB-C routing
  SIM card access: top-right, requires 20 mm clearance with lid open

Mounting position:
  Upright only (antenna orientation fixed in housing)
  Do NOT mount horizontally — battery ventilation path blocked

Adjacent device spacing:
  Minimum 50 mm from other heat-generating devices (PSU, relays)
  Keep away from steel cable conduit running parallel —
  can attenuate 868 MHz Jeweller RF by up to 12 dB

Enclosure recommendation:
  Rittal AX, ABB TwinLine, or equivalent IK10 rated
  Minimum internal depth: 150 mm
  Grounded enclosure body (hub DIN rail adapter is floating)

Barošanas avota un rezerves akumulatora aprēķins

Hub 2 Plus power consumption:
  Standby (Ethernet + 1 SIM active): 130 mA at 12V = 1.56 W
  Full load (alarm + GSM transmitting): ~300 mA at 12V = 3.6 W

Fibra line power draw (example install):
  Fibra Line 1: 40 × DoorProtect Fibra @ 0.85 mA = 34 mA
  Fibra Line 2: 20 × MotionProtect Fibra @ 0.85 mA = 17 mA
  Fibra Line 3: 2 × StreetSiren Fibra @ 2.5 mA = 5 mA
  Fibra Line 4: 1 × Relay Fibra + 1 × KeyPad Fibra = 5 mA
  Total Fibra: 61 mA

Total system standby current: 130 + 61 = 191 mA at 12V

PSU selection:
  Minimum: 12V / 500 mA (0.5 A) — basic installations
  Recommended: 12V / 1 A — with Fibra devices
  EN 54-4 compliant PSU if integrated into fire panel

Built-in battery (3200 mAh at 3.7V = 11.84 Wh):
  At 12V / 191 mA standby: ~18 hours backup (spec confirmed)
  At alarm load 300 mA: ~12 hours

Note: Fibra devices have their own local backup batteries
  separately from the hub battery. Hub battery = hub only.

Zonu reakcijas veidi — konfigurācijas uzziņa

Reaction types (per zone):
  Alarm          — triggers full alarm immediately
  Delayed        — starts entry delay timer before alarm
  Delayed (Entry + Exit) — for entry/exit routes
  24-Hour        — always active, bypasses arm state
                   (panic buttons, smoke detectors, tampers)
  Perimeter      — active in Armed Away + Night modes
  Interior       — active in Armed Away only, bypassed in Night mode

Entry/Exit delay (per group/partition):
  Entry delay:   10–120 seconds (keypad or app disarm required)
  Exit delay:    10–120 seconds (devices bypassed during exit)

Partitions (Groups):
  Up to 9 groups (partitions) per hub
  Each group arms/disarms independently
  Useful for: office hours vs server room 24h vs car park

WallSwitch / Relay Fibra — output zone types:
  Output relay activates on alarm, arm, or custom scenario
  Scenarios created in Ajax → Automation → add rule
  Example: Relay Fibra output → door strike release on disarm

Fibra kabeļa ekranēšana un EMS noteikumi

Shielded Fibra cable grounding:
  Ground shield at HUB END only (single-point grounding)
  Leave shield FLOATING at device end
  Double grounding = ground loop → interference on data line

Separation from 230V mains cables:
  Minimum 50 mm separation (unshielded Fibra)
  Minimum 10 mm separation (shielded Fibra in separate conduit)
  Cross 230V cables at 90° only — never run parallel over 0.5 m

Enclosure grounding:
  Hub DIN rail adapter is NOT bonded to rail automatically
  Connect PE wire from enclosure rail to hub 12V GND terminal
  This bonds hub ground to enclosure PE, reducing common-mode noise

VFD/motor drive environments:
  Use shielded STP cable throughout
  Keep Fibra runs away from motor cable trays
  Add ferrite cores on Fibra cable entry at hub (Wurth 742 721 series)

Hub RF antenna:
  Hub 2 Plus has internal antenna — do NOT enclose in steel box
  Use a plastic ABS enclosure, or steel enclosure with remote
  antenna cable (Ajax sells external antenna adapter separately)
