It is THE solution to warn of hazards.
Schools, businesses and all public facilities must be able to protect all people present on site from external intrusions, attacks, natural disasters (risk of earthquakes, tsunamis, floods), health hazards... and much more.
Message. Flash. Bell: The combination of these functions enables Harmonys Trio to alert everyone in a facility.
In these emergency situations, responsiveness makes all the difference. By simply calling a single predefined number, the GSM control box can be used to remotely trigger an alert in your facility, across all your Harmonys Trio devices.
A text message can also be automatically sent to up to six predefined contacts: police, head teacher, and so on.
