Alarm devices with text message notification to multiple phones

The alarm panel A-1 was developed as a system of monitoring the operation of the climate controllers. It detects the presence of grid voltage and the presence of all controllers connected to the input "LINE". The alarm is equipped with a siren indicating no power or open circuit in controllers connection. In addition, the alarm can be equipped with a GSM module that allows sending text messages to selected phone numbers (max. 3) in case of an alarm. In the absence of voltage 230V alarm uses its own battery.
