The GSM control box allows triggering of lockdown alerts by phone call

Triggering lockdown alerts by phone call

In addition to a Harmonys or a Melodys installation and connected to the SIGMA master clock on its external inputs, the GSM control box triggers a lockdown alert via a phone call from an authorised fixed or mobile line (previously programmed in the GSM control box). Then, the alert is broadcast on Harmonys, Melodys or SIGMA Sound audio systems.

When an alert is triggered, the GSM control box discreetly notifies the police

Discreetly notify the police when an alert is triggered

When an alert is triggered, the GSM control box sends a warning text message to all pre-recorded phone numbers (police, local authorities, mayor, head teacher and so on). To ensure proper dissemination of the alert, up to 50 phone numbers can be set up.
