Relay logic, dry contacts, 4–20 mA — the gear that predates protocols, doing the unglamorous essentials.
Not everything speaks BACnet. The exhaust fan from 1987, the unit heater, the old AHU, the panel with a run light and nothing else — this equipment fails the same slow way modern gear does, but nobody sees it coming because there was never any data to watch. Veritas Data brings it onto the same dashboard as everything else: a contact for run status, a clamp-on CT for current, a 4–20 mA or 0–10 V tap where a signal exists — wired in parallel, without rewiring or interrupting anything.
Exhaust and make-up air, unit heaters, old air handlers, transfer equipment — the gear too old to have a protocol is usually doing a job too basic to be allowed to stop. And because it’s discovered-by-consequence, every failure costs more than it should: the space overheats, the product spoils, the tenant calls, the tech gets dispatched to diagnose from zero. A contact and a current clamp cost almost nothing against one of those mornings.
The same analytics spine as the modern equipment — fed by the simplest signals in the building.
Run status, current draw, and real runtime hours — on equipment that has never reported anything in its life.
Even simple signals trend. Current creep, duty-cycle drift, abnormal start patterns — flagged against each machine’s learned normal.
Service by actual hours instead of guesswork — and a likely cause when the trend turns.
One old supply fan with a clamp-on CT and a run-status contact, with sample data — not a live system. The dashed line is the motor’s overload trip. Analog gear has no alarm before that point — unless someone builds one. Drive the scenarios.
Run status from a dry contact, process values from existing 4–20 mA or 0–10 V signals — landed on our gateway’s inputs alongside what’s already there. Electrician-friendly, familiar, reversible.
Current sensing that clamps around the existing conductor. No lugs lifted, no circuit opened, no downtime to install.
The 1987 fan and the 2024 chiller, side by side, each with its own learned normal. One view, whole building.
Parallel wiring, clamp-on sensing, observation only. The starter, the relay logic, the safeties — everything keeps working exactly the way it has for decades. We watch; we don’t touch.
Where half the mechanical room predates every protocol — and replacement isn’t in this year’s budget, or the next’s.
Fans, blowers, conveyors, heaters — simple machines whose stoppage isn’t simple at all.
Teams tired of discovering failures by walking into them — who’d rather get the contact closure at 2:01 a.m. than the phone call at 8.
Tell us what you run — even the gear from 1987. We’ll design the monitoring for it.
