MSX-CTI/903P1/ACS

Fixture-integrated mesh controller · 1-pin audio jack · 500 nodes

Mesh anchor and relay for an indoor ⒶCS network. Plugs into the luminaire's 1-pin audio-jack port and runs off the fixture driver. Coordinates up to 500 sensor and switch nodes, links the mesh to the ⒶCS app for commissioning and reporting, and reroutes around failed nodes. Best practice is one per zone or floor.

How it works

One controller anchors the whole mesh.

ACS mesh: fixtures relay to each other; the app commissions the network.CTRLSENSORS + SWITCHES JOIN AS NODES; THE CONTROLLER ANCHORSOne controller anchors the mesh · up to 500 nodesⒶCS appQR-code onboardingcommission · configure · scheduleⒶCS clouddaily energy + occupancymulti-site dashboard · rebate exportCLOUD UNREACHABLE → LOCAL CONTROL CONTINUES

Anchor

Coordinates the mesh

Anchors up to 500 sensor and switch nodes per network.

Relay

Self-healing

Traffic reroutes around a failed node automatically.

Status

Status LED

Shows pairing and network health at a glance.

Resilient

Cloud drops, lights don't

Local occupancy, daylight and schedules continue unchanged. Reports queue and upload on reconnect.

Range

Not sure which platform?

Standalone, mesh or enterprise.

Start from the job: one fixture that dims itself, a building you want to see and report on, or a network that talks to the BMS.
