Ask a business owner whether they actually own their fire alarm system, and a lot of them can't say for sure. They're leasing the hardware, tied to one monitoring company, and stuck the day they try to switch. Somewhere along the line, the system stopped being theirs. That's the problem we started JK Alarms to solve.
We're a small, family-owned low-voltage company in Tempe, focused on fire alarms and serving Phoenix and the wider Valley, with security and gas detection systems for the same properties we protect. Every design answers to one person: the end user who lives with the system long after we've finished the job. It's built to code, kept non-proprietary, and it stays yours, not ours.

We stay focused on what we do best. Fire alarms are our core, so for other disciplines like sprinkler and extinguisher work, we partner with licensed fire companies rather than pretending to be experts at everything. That focus is exactly why our fire alarm work holds up. We offer full turnkey service from pre-construction all the way to final inspection, so one company carries your project from the first drawing to the day it passes.
Plenty of companies will install a system. Fewer will design one that keeps working in your favor long after the install is done.
Your equipment is yours, purchased and owned, never leased. That means no monthly hostage payments and no losing your system the day you decide to switch providers. You paid for it, so you keep it.
We use non-proprietary systems on purpose. Proprietary hardware locks you into a handful of dealers who can charge whatever they like for service. Ours keeps your options open, so you're free to choose who handles your service, maintenance, and monitoring down the road.
We design to meet code minimums, which gives you full compliance without paying for extras you don't need. The goal is to keep your long-term maintenance costs and headaches low, not to inflate the invoice.
As our founder puts it, "We always keep the end user in mind when designing our systems to minimize long term maintenance costs and challenges." That's Jeffrey Kerr, President and Founder, and it's the standard the whole company works to.
Everything we build starts with your property and the risks that are actually there. Our work covers fire alarm systems, security and CCTV, and gas detection, each designed, installed, and supported as part of one turnkey service. Whether it's a large office complex, a medical facility, or a family home, we handle every phase reliably and economically.
When you work with us, you’re working with your neighbors.
Don't see your question here? We're happy to walk through the specifics of your property.
Ask Us DirectlyYes. We're a small, family-owned low-voltage company based in Tempe, Arizona. That structure is deliberate, because it keeps us accountable to the people we work for rather than to sales quotas.
You own it outright. We don't lease equipment or hold your system hostage to a monthly contract. Once it's installed and paid for, it's yours to keep no matter who you use for service later.
It means your system isn't locked to a small group of dealers. With non-proprietary equipment, you're free to choose who provides your service, maintenance, and monitoring over the life of the system, which protects you from being overcharged down the road.
Fire alarms are our specialty, and we also design and install security, CCTV, and gas detection systems. For disciplines like sprinkler and extinguisher work, we partner with licensed fire companies so every part of your project is handled by a true expert.
It covers everything from pre-construction through final inspection: planning, budgeting, permitting, installation, monitoring, and ongoing maintenance. One company owns the whole process, so nothing falls between vendors.
We serve Phoenix, Tempe, and communities across the greater Valley. Being locally based means faster service response and familiarity with the codes and inspectors in our region.
We design to meet code minimums, which gives you full compliance without paying for hardware you don't need. Combined with non-proprietary equipment and ownership of your system, that keeps your long-term service and maintenance costs down.
