Commercial Fire Alarm

When it comes to fire, there is no room for error. Mistakes, cutting corners – they can cost lives and irreparable damage. That’s why there are many building codes and regulations in place for fire alarm systems (learn more). At Northwestern Ohio Security Systems (NWOSS), our team of certified Fire Alarm experts is here to help your business stay compliant with these codes. We are committed to never compromise occupant safety, business assets, or AHJ compliance. NWOSS is your one-stop-shop for commercial fire alarm systems.

I really appreciate everything

Just wanted to send a quick note of thanks to your team, Anthony especially for getting our Canton branch cameras back on line so quick. I really appreciate everything. Thanks!

Great Outcome

N.W.O.S.S. did an outstanding job of installing a security system with security cameras at our office at the front and back doors, and at a very reasonable price.

Outstanding Delivery

[Regarding 3-year, campus-wide project] NWOSS hasn’t missed a deadline, they’ve been on top of it from day one. Their delivery has been outstanding.


Westfield Group

Thanks for the amazing service and support

One of your guys came out and replaced our backup battery yesterday. We’ve had a couple issues recently with the system but nothing unrealistic, and Cory’s responsiveness and corrective actions have been phenomenal on every occasion. Our COO is singing your praises and our CEO was just mentioning whether you offer residential services since he’s seen your personalized service has outperformed your competitor’s (his home provider). Nice work by the whole team at NWOSS. Thanks for the amazing service and support and backing up my faith in selecting NWOSS for our security.


Prince & Izant

Thank you for excellent service.

I am 79, and the Mercer County Historical Society Members continue to elect me as their President. I value NWOSS because you take care of our Security System, and I do not have to worry about it. I can trust you, and that trust means more to me, in friendship as well as in business, than money. I realize that I have not taken time to thank you for your excellent service. If I recall correctly, you began your security service to our organization when I was 53 years old. That means that you have given us the best service than any Security System can give us, for over a quarter of a century. I am sending you a very sincere thank you for taking care of the Security of the Mercer County Historical Museum, for the Mercer County Historical Society, Inc., Celina, Ohio.

The Best for Fire, Burglary, Access Control, CCTV systems

I have been with Yaskawa Motoman Robotics since we started the company over 30 years ago and I have been working with NWOSS for over 20 years. We worked with a couple of other security vendors early on and quickly learned that you get what you pay for, (poor equipment, installation, and service)! Since working with NWOSS our company has grown into a large international organization with facilities throughout the US, Canada, Mexico, and Brazil. NWOSS has grown with us and has always been there for us when we need them. The have an excellent, knowledgeable staff, impeccable customer service and a wide ranging product line to choose from. If you or your company needs security and/or fire protection you need to contact NWOSS. They are a first rate organization. I would recommend them without reservation and that is something I very rarely do.
