The Smartvest Wireless Door Bell is a Smartvest extension for signalling indoors. The door bell supports five different signal tones and can play the signals at three different volumes (four door bell tones, one alarm tone). The triggers for a signal can be individually configured. This means that the Wireless Door Bell is suitable for use as a door bell and a sounder. Automatic supervision (functional tests repeated daily) to the alarm control panel means that you can monitor the door bells functionality at all times and can react to a low battery in good time.
