What We Do
We don't just install and disappear. Island AVNS handles every phase of your fire alarm system — from initial design through ongoing inspections and 24/7 monitoring.
We design your fire alarm system to meet all applicable codes — NFPA 72, NYS Building Code, and local AHJ requirements. Every system is engineered for your specific building before a single device is installed.
Working with builders, contractors, and architects on new construction throughout Long Island. We coordinate rough-in wiring, device placement, panel installation, and final commissioning — fully permitted and inspected.
Upgrading an outdated system or bringing a building into compliance? We retrofit existing buildings with minimal disruption — often working nights and weekends to avoid closing your business.
Annual, semi-annual, and quarterly fire alarm inspections required by the AHJ and your insurance carrier. We provide fully documented inspection reports ready for the Fire Marshal or building inspector.
Your fire alarm connects to our UL-listed central monitoring station. The moment an alarm activates, the fire department is notified — even if no one is in the building. We monitor residential and commercial systems alike.
Trouble signals, malfunctioning devices, false alarms — our technicians diagnose and repair fire alarm systems fast. We service most major brands and carry common replacement parts in our trucks.
How It Works
We've installed hundreds of fire alarm systems across Long Island. Here's exactly how every job goes — no surprises, no delays.
We walk the property, assess code requirements, and identify the right system for your building. No charge, no obligation.
We engineer the layout — panel location, device placement, zoning — and prepare permit drawings for the AHJ.
We pull all required permits and coordinate with your local Fire Marshal or building department before any work begins.
Our licensed technicians install the full system — panels, detectors, pull stations, strobes, and notification devices.
Full system test with the Fire Marshal on-site. We walk you through operation, hand over documentation, and connect monitoring.
Code & Compliance
Every Island AVNS installation is engineered to meet the applicable code for your building type and jurisdiction. We work directly with your local AHJ — no extra homework for you.
Long Island has multiple jurisdictions — Nassau County, Suffolk County, and dozens of individual towns and villages each with their own Fire Marshal. We know them all, and we handle the permit and inspection process from start to finish.
The primary standard governing fire alarm system design, installation, testing, and maintenance. Every Island AVNS system is fully compliant.
Governs when fire alarm systems are required based on building occupancy type, size, and use. We determine your requirements during the site survey.
Applies to commercial occupancies, schools, healthcare facilities, and multi-family housing. Dictates detector types, notification requirements, and egress signaling.
Your local Fire Marshal may have requirements beyond state code. We know Long Island's municipalities and build your system to satisfy all of them.
Equipment
We install and service equipment from the most trusted names in the fire alarm industry. Every product we use is UL listed and appropriate for its application.

By the Numbers
Common Questions
Questions we hear every week from Long Island homeowners and business owners. Don't see yours? Call us — we're happy to talk through your situation.
It depends on your building type, occupancy, and square footage. In New York, most commercial buildings, multi-family homes (3+ units), and places of assembly require a permitted fire alarm system. We determine your requirements during a free site survey — no guesswork.
NFPA 72 requires annual inspections for most commercial systems. Some systems — particularly in high-occupancy or high-hazard environments — require semi-annual or quarterly testing. Your insurance carrier may also have specific inspection requirements. We'll set you up on the right schedule.
Often, yes. We assess your existing system and determine what can be retained and what needs to be updated to meet current code. Partial upgrades can be significantly less expensive than full replacements — and we'll always give you an honest assessment of which option makes more sense.
An unmonitored system sounds a local alarm only — no one is notified unless someone in the building calls 911. A monitored system connects to a central station that automatically dispatches the fire department the moment an alarm triggers, even if the building is empty. We strongly recommend monitored systems for all commercial and residential applications.
A typical single-family home takes one day. Small commercial buildings typically take 1–3 days. Larger commercial or multi-floor buildings may take a week or more depending on size and complexity. We'll give you an accurate timeline during the site survey and work around your schedule wherever possible.
Yes — always. Every fire alarm installation on Long Island requires permits and inspection by the local Authority Having Jurisdiction (AHJ). We handle the entire permit process, prepare the required drawings, and coordinate the final inspection with your Fire Marshal. You don't have to deal with any of it.
False alarms are frustrating — and they can result in fines from your municipality. If your system is generating false alarms, there's usually an identifiable cause: a dirty detector, a malfunctioning device, or improper system programming. Call us and we'll diagnose and resolve the issue quickly.
In most cases, yes. Our technicians are trained on all major fire alarm brands including Potter, Notifier, Honeywell, Simplex, and System Sensor. If you have an existing system that needs service, inspection, or repair, give us a call and we'll let you know if we can support it.
