Guest control core · model entry
RCU is core guest-control deliverable — IPTV/phone/CCTV coordinated by GC; open interface standards.
Tender citation · three-step method
LV GC scope defines five-layer duties first, then guest experience chapter.
PurePoint Smartprimary deliverable RCU+panels+modules; other subsystems note implementer.
Cite standard room LV topology andFour deployment routes。
* Multi-network install coordinated by GC/integrator; guest control provides standard protocol and terminal defs.
LV layered responsibility stack
Click subsystem for primary deliverable, interface and PurePoint Smart boundary — cite in GC tender "System boundary" chapter.
Interface:HDMI / IP · RS232 optional info-panel key linkage
PurePoint Smart boundary:Info panel keys optional scene linkage; no license or content delivery
Wiring:Separate LV chase from RCU to avoid conduit interference
Interface:AP / POE · separate feed from RCU enclosure
PurePoint Smart boundary:RCU and AP physically isolated; no Wi-Fi auth software provided
Wiring:LV shaft zone labels; GC coordinates penetrations
Interface:PMS API / lock-network gateway · room status drives card power and lock
PurePoint Smart boundary:Dry contact and register docs; not PMS / lock-network software delivery
Commissioning:seeProtocol integration、Contactless timeline
Interface:RS485 / Modbus · star or bus to modules
PurePoint Smart boundary:Host, modules, drawings, terminal defs, scene table version
Reference:Wired per-room wiring table·Standard room master solution
Interface:LV star to RCU · box standard
PurePoint Smart boundary:Panel, card power, door sign, sensor hardware and silkscreen
Acceptance:Key legend + scene table + finish samples (upscale OEM)
