Power & access control

PACsys™

A property-wide power and access control system for hotels. PACsys manages guest-room electrical state, the housekeeping workflow and the check-in cycle — then puts every property you operate on one live dashboard.

  • ~300 properties in production
  • 50+ HMS / PMS vendors
  • Independent AC & load control
  • On-premises, cloud or hybrid

The portal

Every room, on one screen

Occupancy, device health, today's events and the open task list — the moment they change. Reception, housekeeping and maintenance all work from the same live picture.

Interface preview — property names and figures are illustrative.

How it fits together

One controller per floor, in the distribution board

PACsys does not put a box in every guest room. The controller lives in the floor distribution board and switches the lighting, the air conditioning, the sockets and anything else wired into it — which is why it goes into a hotel that is already trading as readily as into a new build. Keycard control is a separate component, the PACsys AT series, added only where you want it.

New build, renovation or a hotel that never closes
Because the equipment sits in the floor distribution board, the work happens in the riser rather than in occupied rooms. A property is wired floor by floor while the rest of it keeps trading — which is what makes a retrofit viable rather than a shutdown.
Lighting, AC, sockets and whatever else is wired in
Every load is switched on its own rather than through one master relay. You decide what the system controls and what it leaves alone, circuit by circuit.
Keycard control is a separate component — the AT series
PACsys AT adds keycard-based control of the other loads, so the room follows the guest. It is ordered when you want it and left out when you do not: without it the same controller runs on occupancy, schedule or the front desk, and nothing about the installation changes.
The floor keeps running on its own
Each controller holds the state for its own rooms and carries on enforcing it if the server goes quiet. Losing the server does not unpower a floor or lock anyone out.

Hardware

Built to outlast the refurbishment

Guest-room hardware is judged on how long it stays fitted, not on what it costs to fit. The TES5001 series has been developed continuously since the first installation rather than discontinued and reinvented — which is why a property wired two decades ago is still a property we support.

Port counts exist so a property buys the capacity it has, rather than a catalogue size. The AT series is built against the order — which circuits a hotel wants under keycard control is rarely the same twice.

Capabilities

What PACsys gives your operation

50+ HMS and PMS integrations

Over fifty hotel and property management systems already send us check-in, check-out and room-move events. Whatever your properties run — or inherit through an acquisition — the odds are we have integrated with it before.

Independent control of every load

The air conditioner, the lighting circuits, the geyser, the balcony sockets — each is a separately addressable load, not one master relay. Switch any of them individually from the dashboard or bind them to the guest lifecycle.

Keycard-driven power

The keycard governs the AC and any secondary load you choose to put behind it. Pull the card and the room reverts to your policy; put it back and it returns to the guest’s setting — with the front desk able to override either way.

Real-time multi-property dashboard

Live room state across every property in a single view, pushed rather than polled. What happens on the floor reaches the screen in well under a second.

Guest lifecycle automation

Check-in, check-out, room moves and stay amendments arrive from the property management system and actuate the room automatically — with guards that refuse an unsafe or stale command.

Housekeeping workflow

Room status, cleaning state and maintenance flags tracked as a live queue. Supervisors see overdue rooms without walking the corridor.

Mobile-first remote diagnostics

An engineer in front of the rack can enumerate serial ports, restart the service under a watchdog, sweep every controller with live per-device results, and read serial numbers and firmware versions straight off the bus.

Managed rollouts

Choose a version and a set of properties; endpoints update themselves at the next check-in. Staggered, version-gated and reversible, with development releases fenced off from production.

Resilient to bad networks

Properties on unreliable connectivity keep operating. Events queue locally and ship in order once the link is back — nothing is dropped in the gap.

Role-based access control

Built-in roles for administrators, managers and viewers, plus custom roles you define. Permissions are granular and enforced at the API, not just hidden in the interface.

Data isolation per property

Each property keeps its own database and the central layer rolls up. No shared-tenant surprises, no noisy-neighbour performance issues.

Complete audit trail

Every meaningful action — check-in, command, administrative override — recorded with actor, target and timestamp.

Who uses it

Four very different people, one system

A receptionist and a field engineer need almost nothing in common from the same product. PACsys gives each of them their own surface.

Front desk

Check-in and check-out, room shifts, and the current state of every room on the floor.

Housekeeping supervisor

The live cleaning queue, overdue rooms, and direct control of room fixtures.

Support engineer

Property health across the estate, version rollouts, and diagnostics per client.

Field engineer

Serial-level bus debugging from a phone while standing at the rack.

For your IT team

Boring infrastructure, on purpose

Nothing here needs a platform team to operate. If your IT department can run a Windows or Linux server and a SQL database, they can run PACsys.

Standard server stack

Modern .NET on the server side with SQL Server for storage. No container orchestration required.

Outbound-only connectivity

Properties reach out to the central service. No inbound firewall rules or site-to-site VPNs to negotiate.

Encrypted end to end

TLS in transit and transparent database encryption at rest, with token-based authentication throughout.

Live updates that degrade well

Real-time push falls back gracefully on restrictive corporate networks rather than failing outright.

Licensed per machine

On-premises installations are hardware-bound, so a licence cannot quietly walk to another site.

Fast, reversible deploys

Updates apply in seconds with a single-command rollback if a release misbehaves.

PACsys Network

Operating more than one property? The multi-property layer of PACsys puts every installation you run on a single live dashboard, with fleet rollouts and remote diagnostics.
