Telephone / GSM transmitters

Telephone and GSM diallers provide a reliable way to secure your property with instant alerts delivered directly to your mobile phone. These devices send real-time system status reports via call and/or SMS, and can be connected to any dry-contact (NO/NC) detection elements for flexible integration. With ultra-simple operation, there’s no app required, the dialler contacts you directly in the event of an alert. Perfect for upgrading or replacing outdated landline-based systems, telephone and GSM diallers ensure fast, dependable communication when it matters most.
