MSP-SRI/903P1/ACS

Fixture-integrated PIR sensor · 1-pin audio jack · wireless mesh

PIR occupancy sensor that plugs into the 1-pin audio-jack port on ⒶRCH luminaires, at the factory or in the field. Powered by the fixture's own driver. Joins an ⒶCS mesh of up to 500 nodes and commissions from the ⒶCS app by QR code: no gateway, no IT, no on-site Wi-Fi. If the cloud is unreachable, occupancy, daylight and schedules keep running.

How it works

Plug in, scan, and the fixtures find each other.

ACS mesh: fixtures relay to each other; the app commissions the network.EACH NODE = A LUMINAIRE WITH A PLUG-IN SENSORUp to 500 nodes per mesh · 30–50 ft node spacing indoorsⒶCS appQR-code onboardingcommission · configure · scheduleⒶCS clouddaily energy + occupancymulti-site dashboard · rebate exportCLOUD UNREACHABLE → LOCAL CONTROL CONTINUES

Commission

QR code, no gateway

Pair from the ⒶCS app. The datasheet quotes under 30 minutes for a typical 10,000 ft² space.

Mesh

Up to 500 nodes

Self-healing multi-hop relay. 30–50 ft between nodes indoors.

Report

Energy + occupancy

Daily reporting to the ⒶCS cloud: multi-site dashboard and DLC NLC rebate export.

Resilient

Cloud drops, lights don't

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

Detection

8 ft radius. About 690 ft² at a 13 ft ceiling.
