A·IQ is one on-premise platform for the two jobs every facility team fights daily: making sense of the alarms, and running the work. Signal cuts the noise and finds the fault. Nexus already knows the asset and cuts the work order. One database. Unlimited users. Nothing leaves your network.
Signal and Nexus each solve a real problem on their own. Run them together and every fault Signal finds becomes a Nexus work order, on the right asset, automatically.
Stop living in the alarm console. Signal reads your BAS over BACnet, Modbus, and OPC UA, cuts alarm noise by roughly 80%, scores the bad actors, and layers fault detection, root-cause, and energy analytics on top. ISA 18.2 aligned.
A full CMMS with the parts most vendors sell separately: asset registry with RPN criticality, mobile work orders, 10-year capital planning, calibration, inventory, and spatial/CAD. One vendor, one login, unlimited seats.
Most teams run alarms in one tool, assets in another, drawings in a third, each with its own login, database, and per-seat bill. A·IQ puts them on one stack that shares identity, assets, and history end to end.
A Signal fault becomes a Nexus work order automatically with the affected asset, its history, and the right runbook attached. No middleware. No copy-paste between consoles.
FusionAuth backs both products. Add a technician once. Permissions, audit logs, MFA same surface across Signal and Nexus.
Signal points and Nexus equipment records reference the same underlying asset. The chiller in your alarm log is the chiller in your work order.
Alarm event, fault detection, work order creation, technician completion, post-work trend verification one continuous record.
A spatial hierarchy tied to BIM, IFC, and CAD. Both products use the same hierarchy. New buildings drop in without re-modeling.
High-cardinality point data, alarm history, energy meters, work order audit all in Timescale with continuous aggregates and compression.
Row-level security per tenant. mTLS between every service. Secrets in OpenBao. The whole stack assumes hostile networks.
The chiller alarm at 04:13. The dispatched technician at 06:00. The verified trend at 08:45. Same record. Same database. No integrators in between.
Postgres, Docker, and open protocols, running on hardware you control. Works with Siemens, JCI, Honeywell, Niagara, or any mix you already have. No proprietary hardware, no rip-and-replace, no data held hostage.

On-premise by default. Cloud-deployable when required. Your facility data never leaves your network.
TLS everywhere, secrets in vault, row-level security on every query. Containerized and isolated so one service going down never takes the rest with it.

Architecture and procurement questions on the A·IQ platform.
No. Signal and Nexus are independently sellable. Most customers start with one and add the other later. Buy both and the closed loop turns on automatically, Signal faults become Nexus work orders on the right asset.
Yes. A·IQ is licensed per site, not per seat. Your entire team, every shift, every trade, gets access with no per-user fee. Most competing tools charge $50-150 per user per month.
Yes. A·IQ speaks BACnet, Modbus, and OPC UA and works across Siemens, Johnson Controls, Honeywell, Niagara, or any mix. No proprietary hardware and no rip-and-replace.
Yes. On-premise is the default and the platform is air-gap capable. Your facility data, BAS topology, and asset records never leave your network.
