We couldnt find a smoke alarm to properly replace the one we had in any stores locally. So we went online and were pleased that we were able to find one that fits and works well. We got one for each level and they all three will go off if there is smoke by one of them. We are pleased.

I received excellent online service to replace my old smoke alarm. New model fit perfectly and easy to install with existing connection.
Other reasons include: It could be a different device or appliance such as a security system, monitor, carbon monoxide alarm, or other device which has a similar low battery or alert signal. Some of the same factors that cause unwanted alarms can cause intermittent alarms: dust and insects in the alarm or power interruptions in hardwired alarms. Improper wiring on AC or AC/DC smoke alarms. AC alarms will chirp every 5 seconds if the interconnect wire is grounded. The orange interconnect wire should NEVER be grounded; it should only be used to interconnect other smoke alarms or compatible devices.
