Local Honeywell certified installer. Burglar alarms, fire panels, and access control on one platform, for homes and businesses.
Mammoth Security is a Honeywell Certified installer serving homes and businesses across New Haven, CT. We design, install, and service Honeywell burglar alarms, fire panels, and access control. We tie them together on one platform you run from a single app.
Every installation starts with a free on-site assessment, and the same in-house crew that designs your system installs, programs, trains you, and services it down the road. No subcontractors. Already have a Honeywell system? We repair, maintain, and monitor those too, even ones another company installed. We also install DMP, Verkada, and Avigilon, so the recommendation you get fits your building.

Honeywell's real strength is that a single platform manages your burglar alarm, fire, access control, and cameras through an app, so you're not juggling four systems and four logins. It scales from a one-bedroom condo to a multi-floor building, and you can add devices later without ripping out what's already there. The hardware has been common in U.S. homes and businesses for decades, a proven, widely available platform.
The biggest challenge with Honeywell is how it's sold: through distribution, not factory-direct. As a company, we'd rather deal straight with the manufacturer. It means faster service, stronger support, and a supply chain we control instead of one we wait on. It's not something you'll experience with your system once it's installed.
We're Honeywell Certified, and we install and service it with our own W-2 technicians. The same crew from the first walk-through to the panel service three years later. No subcontractors.
Honeywell is the right call for many New Haven buildings, but not for everyone. We also install DMP, Verkada, and Avigilon, and we don't carry a quota for any of them. If your building is better served by another brand, we'll tell you. That's the difference between an installer and a single-brand salesperson.

A Honeywell system is a set of parts that work together. A control panel (the brain), sensors (door and window contacts, motion, glass-break), a keypad or touchscreen to arm and disarm, and a backup that keeps it online if power or internet drops. The Total Connect 2.0 app ties the whole thing to your phone. What we install:
We handle the full install on every Honeywell job. Here is what we do most.
New design and installation
Many clients come to us with no system at all. We start with a free assessment, ask what you're actually worried about, and write up a plan covering the panel, sensors, and keypads, then test every part before we leave.
Upgrades and replacements
Got a dated or out-of-warranty Honeywell panel? We swap in a new one and reuse the parts that still work to keep costs down. We did exactly that for Howard's Snacks, replacing their old panel with a new Honeywell VISTA-128.
Setup and training
We connect the system to the app, then sit down with you and walk through arming and disarming, checking sensor status, getting alerts, and viewing cameras on your phone.
Integrated builds
Honeywell can run burglar, fire, and access on one platform, one view of your whole site. That's the setup we build for offices, multi-tenant sites, and apartments that don't want four separate systems.

We install Honeywell home security systems for New Haven residents. Whether you live in an East Rock apartment, a downtown condo, or a Westville rental, the setup is the same.
We start with a free walk-through of your home. Then we plan where to put each sensor, keypad, and camera. A typical home install covers door and window sensors, motion detectors, and a keypad near the front door. The Total Connect 2.0 app comes with it. Many home installs are done in one day.

Our licensed team also installs Honeywell business security systems for sites across New Haven.
A business job is bigger than a home one. The system can include burglar alarm sensors and access readers at the front and back doors. It can also integrate professional security camera installation into one Honeywell platform.
We design the system based on your space size and the number of doors. Our access control services cover keypads, card readers, and biometric scanners for office use.

When we install a Honeywell commercial fire alarm or security system, we prioritize technical accuracy, code compliance, and future scalability. We use a transparent, four-stage process to eliminate guesswork.
Call 203-747-8244
If you already have a Honeywell commercial security system, whether it handles fire, burglary, or access control, we provide full repair, maintenance, and monitoring services. It does not matter if our crew installed it or if another vendor put it in years ago.
We regularly step in to help clients whose original security contractor went out of business or stopped responding. We can take over any Honeywell panel immediately, no release letter or vendor permission required.
Comprehensive Honeywell support
We handle the transition seamlessly so your building stays protected without coverage gaps. Call 203-747-8244

Our teams work with hospitals, banks, apartments, and stores all within the same few miles, so our New Haven commercial building experience shapes our security solutions by industry for real businesses, not cheap home-security checklists with “commercial” stapled to the top. Call 203-747-8244 now!
Yes. We repair, maintain, and monitor Honeywell burglar, fire, and access systems no matter who installed them, and we don't need your old vendor to release the system. We start with a full check, flag anything wrong, and get it back in shape.
We can come out today to assess your space and design a Honeywell system that fits the property. We will set up to run as one integrated system, installed and serviced by the same Honeywell Certified team. We also handle other commercial security work for New Haven businesses.

City Map
Our techs spend a lot of time on New Haven streets, in apartment buildings on Whalley Avenue, in labs near the medical district, in corner stores in Fair Haven, and in homes in East Rock. It's a city where students, scientists, shop owners, and apartment managers share the same blocks, and security needs change block by block. So we don't bring a one-size-fits-all system to a property. We listen first, then design what fits. That's why local owners and managers keep working with us.
We install throughout the city: downtown condos and offices, the multi-tenant blocks along Chapel Street and the State Street corridor, the Yale-area buildings, and homes and rentals in East Rock, Westville, Wooster Square, Fair Haven, Dixwell, Dwight, Science Park, and Long Wharf. Wherever your property sits, our Whalley Ave base gets us there fast.
