Product Overview

The Wireless Smoke Alarm detects smoldering fires and has a voice alarm that's proven to wake children up better than standard alarms. It also has a horn tone with low frequencies for the hearing impaired and elderly. This alarm will sound if it detects smoke even during power outages. It uses a secure radio frequency to communicate between alarms, which are perfect for linking alarms on different floors or in stairwells. No wires necessary and it's programmable with up to eleven locations. Other features include a test and silence button, a latching indicator that remembers which unit initiated the alarm and smart technology that helps reduce false alarms. The SA511B can be connected to other smoke alarms and offers 360˚ access to the smoke sensor. If one unit triggers an alarm, all smoke alarms in the series will sound. The SA511B features a perfect mount system for perfect alignment, a low battery latch and (2) silence features. The Wireless Smoke Alarm is warranted to the original purchaser for a period of 10 years. First Alert invests time and research into providing dependable and hardworking products.

Wireless Interconnect Smoke Detector (2-Pack) is rated 4.5 out of 5 by 13.

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.
