Product Overview

The Wireless Smoke Alarm detects smoldering fires and has a spread spectrum horn tone. This alarm will sound if it detects smoke even during power outages. It uses a secure radio frequency with 65,000 security codes to communicate between alarms, which are perfect for linking alarms on different floors or in stairwells. No wires necessary and it's programmable with multiple alarms for a home safety system. 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 SA520B 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 SA520B features a perfect mount system for perfect alignment, a low battery latch and (2) silence features. You can silence the low-battery chirp for eight hours or temporarily silence a nuisance alarm. The Wireless Smoke Alarm is warranted to the original purchaser for a period of 10 years.

Does the photo-electric sensor make this smoke detector less likely to go off due to steam from my shower?

Customer Reviews

Rated 5.0 out of 5 by 1 reviewer.
Rated 5.0 out of 5.0 by Performs as advertised We installed a combination of fifteen interconnected hard-wire and wireless smokes along with three interconnected wireless CO detectors. All eighteen linked together just as advertised and worked flawlessly. Here's to hoping we never need them but if we do, then we can sleep comfortably knowing we're well protected. October 15, 2013
