Vacant-room cut-off sequence
Standard engineering order from room-state change to circuit cut-off — integrators may layer PMS events, butrelay action must complete locally on the RCU.
RCU local:card power OFF · HVAC/outlet relays open · scene table switches to VC state.
RCU local:lock dry-contact status updated · synced withaccess revoke.
RCU local:configurable cleaning delay window · housekeeping card may turn card power ON (optional).
RCU local:non-essential circuits fully off · vacant power acceptance< 50W (contract metric).
RCU local:DI monitoring continues · alarm bits written · platform upload by integrator.
Sensor points · three input types
BOM by install location — dry contacts to RCU DI, RS485 sensors to module bus.
Bath · PIR
Night-path soft light, mirror light off when vacant; public areas seepublic-area solution.
Bedside / bath · SOS
Dry contact triggers RCU alarm output; audio/visual via integrator platform.
Window · window sensor
Window open stops HVAC (seeHVAC); prevents waste.
Ceiling · smoke dry contact
Fire linkage per property fire code; guest control collects status bit only.
LV box · DI module
8-channel DIexpands input points.
Energy policy comparison
| Policy | Hardware | Effect | Fit |
|---|---|---|---|
| Card-power cut-off | Card-power module | ★★★★★ | Chains / upscale |
| Door sensor + no-card access | Door sensor + RCU | ★★★★☆ | B et amp;B retrofit |
| PIR public areas | PIR sensor | ★★★★☆ | Corridor / bath |
| HVAC vacant limit | FCU module | ★★★★☆ | All properties |
| Sub-metering module | Energy module (optional) | Monitoring focus | Green hotel cert |

Hardware layer · RCU local cut-off
Card power, door sensor, PIR, SOS converge on RCU — cut-off and alarm logic does not depend on WAN.
- Terminal definitions and DI address table with BOM
- Same version ascard-power decision tree
- Vacant cut-off still runs offline
Platform layer · integrator optional
Energy stats, alarm dashboards, group KPI by integrator or third-party platform — Point Pur Intelligent provides API / register export docs.

- Tender summary:energy-saving topic
- No hotel NOC software product

Acceptance checklist
Full vacant cut
VC room: guest card invalid or engineering card timed; measure circuits near zero.
Delayed cut
After card out, lighting/HVAC delay per policy; record timing params.
SOS test
Trigger RCU dry output; platform receives alarm (if present).
Window interlock
Window open enters HVAC protect mode.
