Are these dog friendly and if yes how do they sound an alarm ?

Asked by: Dem14086
The alarm is high pitched buzz/beep and my cats and my wife thought it was quite loud. So, I doubt your dog will like it much but, hey, it is not meant to be pleasant but to keep you alive if there is a fire.

Wireless Interconnect Smoke Detector (2-Pack) is rated 4.4 out of 5 by 9.

I wanted a dual smoke detector ( photo cell and ionization ) as well as carbon monoxide but had to settle for ionization only because no one manufactures a dual detector with CO detection. How dumb is that! So I had to buy a second set of smoke detectors to cover both types of detection. The link between detectors when one detects smoke was via dip switches and easy to set and worked when tested. No fires or smoke yet so I can't tell you if they work well but I am pleased with the products so far.

Rated 5 out of 5 by from Great units easy to install and giving better protection for multiple areas The units were quite easy to program and install for the wireless connection. The video instructions on the CD were good. We have noticed that the unit near the kitchen, does not have the many nuisance alarms that our former unit (of another type) had. In our place, the wireless connection with alarm signals at all units are important, as the garage is under the living quarters. An alarm sounding in the garage would probably not be heard in the bedrooms, if it were not for the wireless connectivity in this system.

Rated 5 out of 5 by from Good Price I purchased this as a replacement and add on to the system I already have. Wireless interconnect is a nice feature. Home Depot had the best price I could find.

Rated 5 out of 5 by from Great product!! I love the smoke detector. I purchased 3 packs for 3 bedroom, basement, living room and hallway. I had trouble getting them interconnected, but I finally got to work. They were expensive but they are worth it.

Rated 5 out of 5 by from keeping my Family Save The smoke detectors was easy to program. I know that we will be safe if there was to be a fire in our home,because its loud and is placed in each room of the home. The price wasn't bad because it came in a two pack with a saving of $15 each.
