Do Honeywell and Johnson Controls compete?

In this catalog they are both placed on 4 of the same parts, across 2 layers: Valves and actuators, Building management, controls, environmental sensors, Detection, Physical security & access. Sharing a part does not mean selling the same product to the same buyer, so read each row's product note.

Which has more placements, Honeywell or Johnson Controls?

Honeywell has 8 placements and Johnson Controls has 10. Placement counts reflect how thoroughly each company has been catalogued as well as its real breadth, so they are not a ranking.

What the shared parts are

Valves and actuators — Valves and actuators that modulate and isolate flow within the facility water loop, including zone-isolation valves that take a section offline without stopping the whole loop.
Building management, controls, environmental sensors — The building management system, PLCs, and environmental sensors that monitor and automatically control chillers, air handlers, pumps, and dampers across the facility.
Detection — Smoke and heat detection, including aspirating detectors that continuously sample air to catch a fault before visible smoke develops.
Physical security & access — Physical access control, video surveillance, perimeter detection, and guarding systems that secure the facility and its data halls.
