The product was put into operation this past weekend. The system puts together two separate buildings into one . A quick sinking with the help of a technician , was a breeze. Thank You ! Frank MCQUADE. a combo, a Smoke & CO system would be great

Wireless Interconnect

Works as advertised. Shipped as promised.

This item did what was expected. It allowed us to connect all of our wireless smoke and carbon monoxide detectors together.

Smoke alarm

Tested good. Synced to other smoke alarm.

Works well

It was easy to install since we had older BRK / First Alert units. Connected with the other units flawlessly.

Awesome product

This product installation is quick and easy. The set up is very labor efficient. This product is loud and will notify you immediately. This is a very good system and needs to be put out to people to let those know about it without alarm systems. Pricing is very reasonable.

Expanded Home System

I had old smoke alarms that I wanted to replace: 2 upstairs, 1 main floor and 1 in the basement. Three I replaced with combo smoke/CO2, the 2nd upstairs unit I purchased a bridge unit to connect the old hard wired to the 4 new battery units. The hardest part was the wired units because the old connectors didn't match any brand of new unit. The detectors came with easy directions and it wasn't that hard. Once set up, all work perfectly together. I like the voice indication, telling you where the fire or co2 issue is located. I am very pleased with the purchase and feel more comfortable with my expanded zone. No extra cost for wiring so although the units are a little more expensive it doesn't cost as much as an electrician!

Great Product

Hardwired systems seamlessly integrated with the multiple First Alert wireless smoke alarms we installed. Now all alarms are integrated throughout our home. Awesome!

Great product. We integrated with 8 other Wireless Smoke Alarms. All linked perfectly together as advertised and we now have comfort of knowing any alarm activation will set off alarms throughout the house.

Had some programming problems

For some reason it was hard to link this one. I have used them before and never had a problem till now. It worked in the end

The quality of this product is very good and responds to my needs.

Easy whole house protection

It was very simple to sync all the smoke alarms in our home. Now we are comforted knowing that if a fire starts in the basement, we will know about it instantly 2 floors above in our bedroom.

I spoke with someone in technical support on a Sunday who was extremely helpful in advising me which products to buy to make my house compliant for a house sale. I ordered 5 products. They all arrived on time and in good shape. They were very easy to install and all worked immediately.
