Fire alarm systems from Johnson Controls
Every fire alarm system relies on a control unit, the central panel that picks up signals and triggers the alarm. Johnson Controls offers Simplex control units straight from the company and Autocall units via partners.
Among the Simplex models are the 4100ES, 4010ES, and 4007ES. They pair with TrueAlarm sensors that pick up smoke, and TrueAlert ES notification appliances, meaning the horns and strobes that alert occupants.
Johnson Controls built the Foundation series of control units for small to midsize buildings. The company says its notification devices stay electronically supervised 24 hours a day and are able to run self-tests.
Your panel choice shapes who can maintain it down the road, so go over it with a fire protection contractor first. Call now and someone local can walk through the choices with you.

Sprinklers, extinguishers, and other suppression
Johnson Controls makes, configures, and puts in sprinklers, valves, extinguishers, extinguishing agents, and special-hazard systems. Design, installation, and project management are also part of what it provides on these jobs.
The company says its patent on the modern fire sprinkler goes back more than 140 years, to Frederick Grinnell's invention.
For portable units, it covers the A, B, C, D, and K fire classes. Its extinguishing agents range from water and dry chemical to CO2, Purple K, Metal-X, and FE36, and the units shown carry the ANSUL brand, with K-GUARD restaurant extinguishers among them.
During inspections, technicians scan barcodes on each extinguisher and the hazard it protects. Electronic Inspection Reporting then follows every unit across its lifecycle. Leasing is an option too, with service and inspection bundled in, and there's a lease-to-own plan as well.
