David came to fix the keypad on our fairly dated house alarm and serviced it after various checks and reset it, that the keypad is working as good as new. Thankfully no more waking the neighbours in the middle of the night because it couldn’t be switched off. A pleasant professional young man to deal with. Would highly recommend Beacon Security. When we do get around to upgrading our system, we will be contacting Beacon Security. 5* service to do so.

I use these guys for all my sites now. Very reliable, trustworthy and it hard to put a price on security but they are very reasonable. Highly recommended. Ahead on tech.

Review for 3E Fire & Security (formerly Beacon Security): I recently used 3E Fire & Security for a home alarm/ CCTV setup, and I was extremely impressed with the professionalism and quality of their work. Dave was punctual, knowledgeable, and friendly throughout the entire process. He took the time to explain everything clearly and ensured the job was completed efficiently and to a high standard. I felt confident in their expertise and appreciated the excellent customer service. I would highly recommend 3E Fire & Security to anyone looking for reliable and trustworthy security solutions. Thank you again for a great experience! Santino.

It was an absolute pleasure to deal with 3E and Dave from the beginning. He was recommended to me by a friend after a break-in. He was very knowledgeable, professional, trustworthy, courteous, and quick. His alarm system is state of the art and gives us great peace of mind. I recommend him heartily (and already have) without reservation.

3E Fire & Security are an excellent company to deal with Dave has been looking after my Security for many years now he put in the first camera system for me many years ago and the service I get from him is first class. I got him to upgrade the complete system around 2 years ago I found this to be an excellent system. It has paid for itself many times over you can watch everything from your phone no matter where you are let it be out of the country or in your armchair at home. It also makes it very safe as you can see what's going on and if there is someone breaking in you can call the guards immediately without getting yourself harmed in any way you also have video footage of everything that goes on on your premises keep up the good work and wishing 3E Fire and Security every success in the future. Dave has my no if anyone wants to contact me for a reference in any way

Had Dave around to install a system several years ago. Friendly, reliable and thoroughly professional. All done in a few hours, very tidy and easy to do business with. App supported so peace of mind on the go. Pretty good value in the current climate and couldn't recommend Beacon highly enough. Best of luck to an excellent Irish business.
