Family owned & operated
Licensed & insured electrical and alarm contractor
24/7/365 monitoring — serving all of Florida
Design, installation, electrical, monitoring, inspection and service stay under one roof — so nothing falls between two vendors when a device trips at 2am.
Addressable and conventional fire alarm design, installation and takeover — engineered to the applicable NFPA 72 and local AHJ requirements.
Perimeter and interior detection tuned to how your building actually operates, so the system gets armed instead of ignored.
IP camera systems with clear coverage of the doors, drives and assets that matter — plus recorded evidence you can actually retrieve.
Credential-based entry with schedules, audit history and instant lockdown — replacing key rings nobody can account for.
We are a licensed electrical contractor, so the power your life-safety and security systems depend on is our work too — not a second trade you have to schedule around us.
Scheduled inspection, testing and documentation of life-safety systems, with deficiency reports written so the fix is obvious.
Troubleshooting, parts replacement and emergency response for systems we installed and systems we inherit from someone else.
A warehouse, a clinic and a restaurant fail in different ways. The design changes accordingly — the standard of work does not.
Multi-tenant buildings, suites and campuses with mixed access needs.
Open/close reporting, back-of-house coverage and after-hours protection.
Large-footprint detection, yard coverage and equipment protection.
Life-safety systems with documentation regulators expect to see.
Lockdown, notification and access control across buildings and schedules.
Homes, condos and community properties, monitored the same way.
Monitoring is only as good as the sequence behind it. Here is the path a signal takes from your building to a dispatched responder.
System armed
Illustrative panel — not a live feed.
EmergencyThe panel transmits over its primary path, with cellular or IP backup if the primary is cut.
The central station identifies the zone, the device and the alarm type before acting.
Your call list is worked in the order you set, including verification passcodes.
Fire, police or EMS is dispatched per the alarm type and your written response plan.
Every event is logged and available to you afterwards for insurance and review.
Response times depend on your local fire, police and EMS agencies — not on the alarm company. What NSS controls is how fast the signal is verified and passed on, and that sequence goes in writing with your response plan.
Every device tested. Every signal verified. Every report signed, dated and handed to you. Safety first is what that costs us — and it is the only reason the phrase means anything.
The same crew that designs your system installs it, pulls the power for it, tests it in front of your authority having jurisdiction, and comes back for the inspection. It is a family business, and nothing about that is subcontracted away.
Our name sits on the panel by the door. That is the whole reason the work is done this way.
The people who own this company are the people who answer the phone and stand behind the work. An escalation here reaches an owner, not a regional queue.
Alarm, video, access and the electrical work behind them are all in house, so power and low-voltage are not two trades blaming each other on your job.
Design, permits, installation, monitoring and inspections stay with NSS. No hand-off to a subcontractor you never met.
We install equipment we stock parts for and train on, so a failed device is a service call — not a full replacement quote.
Inspection reports, as-builts and test records arrive in a form your AHJ, insurer and property manager will accept.
If a smaller system does the job, that is what we quote. Coverage gaps get flagged in writing, not discovered later.

Steps from walkthrough to inspection
Five stages, each with a named deliverable. You always know what happens next and who is doing it.
We survey the property, note code requirements and listen to how the space is actually used.
You get a device-level scope, drawings where required, and a price with no line items left vague.
Permitting is handled, then installed by our own technicians around your operating hours.
Acceptance testing with the AHJ, then hands-on training for the people who arm and disarm it.
Monitoring goes live, inspections get scheduled, and service is one number away.
If your question is not here, ask it in the form below — you will get a real answer, not a sales call script.
Usually, yes. We inspect the existing panel and devices, tell you honestly what is reusable and what is end-of-life, and quote the takeover against a full replacement so you can compare the two.
Tell us about the property and what you are protecting. A technician reviews it and gets back to you with next steps — no obligation.
