Review on π₯ SA521CN-3ST Hardwired Wireless Smoke Alarm with Photoelectric Sensor and Battery Backup - FIRST ALERT by Eric Nallamothu
Pretty mad! c Smoke detectors and fire alarms
These things seem to work in principle, but they are very difficult to connect. From a practical point of view, the instructions do not help with the connection process. Eventually I called First Alert and a very helpful customer service representative helped me find another and more productive way. After they were all installed, they would turn off at odd times. Then, after about 20 seconds, they stopped. Tried to fix the system but that didn't help either. Now they are all removed. When I tried calling the phone number for professional installation guidance it didn't work. I will try to install them again. If that doesn't work, I don't know what to do with 14 SA 521, they are too small for boat anchors! To put it mildly, it was very uncomfortable!
