Designed for your building, installed in phases so you stay open. You deal with the same in-house team from design, installation, monitoring, and maintenance.
Mammoth Security designs and installs commercial fire alarm systems for New Haven businesses. We work in offices, warehouses, retail, schools, and municipal buildings. We start with a free on-site survey. Next, we design an addressable or conventional system based on how your building is actually used and install it in phases, so you stay open the whole time.
Everything complies with NFPA 72 and the New Haven Fire Code, and you receive full documentation at handover. For fire alarm projects within our New Haven Commercial Security Services, the same in-house crew designs, installs, programs, tests, and services your system down the road, with no subcontractors and no handoff.

No two buildings get the same system. We start with a free on-site survey and design around how your space is actually used: zone-by-zone separation for a multi-tenant office, high-ceiling and aspirating detection for a warehouse, voice evacuation for a school gym, mapped notification for a council chamber.
Then we install it in phases so the business keeps running. Cable pulls and dusty work happen after hours. New panels and detectors come online one section at a time while the old system stays live everywhere else. For a medical office, a school, or a busy retail center, that phased approach is the difference between a new system and a shutdown.
And the same in-house crew that designs it installs it, programs it, tests it, and services it for years after- no subcontractors, no handoff to a company you've never met.
Call 203-747-8244 to get a customized system for your business.
Every building type carries its own zone count, device mix, and integration needs. We design around how the space gets used day to day.

Most commercial installs happen in buildings that can't close for the work, so we phase the project to keep the business running. It's the standard approach for medical offices, schools, and busy retail centers to save the owner rent, payroll, and downtime.
Most owners put the new system on a fixed annual maintenance schedule once it's live.
You don’t have to close your business to install a fire alarm system. Call 203-747-8244, and we will figure out a perfect schedule for you.
Most security companies standardize on one or two panels and install them everywhere, whether they fit or not. We carry several commercial-grade lines and pick the one the building actually calls for:
Many properties pair the install with commercial fire alarm monitoring for off-site supervision and signal response.
New Haven's building mix runs from 1800s downtown blocks to glass towers from the 2010s, and the system has to fit the building in front of it. What shapes a local install:

Our New Haven team is also available for:
In most cases, yes. The panel needs a reliable path to reach the monitoring center. Cellular and internet connections have largely replaced old copper landlines in newer installs.
Sometimes. The panel can move with you if it fits the new building's size and zone count. The wiring, detectors, and notification appliances usually stay with the original building because they're built into the structure.
We design each system around the building and how the business runs in it, from older downtown blocks to newer Yale-area offices. Every project includes panel programming, full device testing, and written documentation for your safety records, with a single team for design, installation, programming, and follow-up.

City Map
New Haven is a commercial hub for retail, dining, and professional services, with most of its business corridors clustered between the Yale campus and the harbor. Downtown is dense and walkable, which means many businesses share fire alarm panels across multi-tenant blocks, so a new system has to account for the neighbors, not just your own suite. We've installed across that downtown core and out into the newer Yale-area buildings.
