Is HomeBase necessary to receive notifications?
Yes. The sensor uses efficient Sub-1G communication with HomeBase to maximize battery life. HomeBase relays the sensor's message to you via the internet. Now compatible with both HomeBase S380 and S280.
What is the maximum operating distance from the listener to HomeBase?
The maximum operating distance is 200 meters.
What is included in the box?
The box contains 1 Quick Start Guide (QSG), 1 Smoke Alarm Listener, 1 CR123 Battery, and 1 pack of screws.
Why is it called a 'listener'?
Because it does not detect smoke directly. It listens for the sound of existing smoke alarms and alerts you if they are heard.
