Fire Alarm Systems
What a Fire Alarm System Actually Does
A fire alarm system is a network of interconnected alarm units, hardwired into your electrical system, that communicate with each other — when one detects smoke or heat, every unit on the system sounds. That’s different from a single smoke detector working alone. Property owners typically need this level of coverage for multi-family buildings, rentals, larger single-family homes, and any property where local fire code requires interconnected alarms rather than standalone units.
Landlords and property managers are the most common customers here, since most jurisdictions require interconnected, hardwired alarm coverage in rental units and multi-unit buildings, with battery backup so the system keeps working through a power outage. We handle the full job: wiring, interconnection, placement per code, and backup power, plus a written estimate before any work starts.

What Our Clients Say
★★★★★
“Interconnection is the piece people miss most. A standalone detector in one bedroom doesn’t help anyone two rooms away — the system has to talk to itself.”

★★★★★
“We manage four rental units and needed everything up to code before renewal. They wired the whole system in a day and gave us the paperwork for our inspection.”

Questions
Fire Alarm Installation FAQs
Do rental properties require an interconnected fire alarm system?
Most jurisdictions require rental and multi-family properties to have interconnected, hardwired alarms with battery backup, not just standalone detectors. Requirements vary by state and city, so check your local fire code or ask us to confirm during the estimate.
What’s the difference between a fire alarm system and a smoke detector?
A fire alarm system links multiple detection units together so they all sound at once when any one triggers. A standalone smoke detector only alerts the room it’s installed in. See our Smoke Detector Installation page if you just need individual units.
Can an existing smoke detector setup be converted into an interconnected system?
In most cases, yes — we can rewire existing units into an interconnected system or add compatible hardwired units to your current setup, depending on your home’s wiring and panel capacity.
How long does fire alarm system installation take?
Timing depends on property size and how many units need wiring and interconnection. Single-family homes are often done in a day; multi-family properties may take longer. We’ll give you a specific timeline during your on-site estimate.
