GSM telephone transmitter

Being linked to a private telephone network (mobile or fixed) or to a regional surveillance company can be provided by the Alerte Rouge GSM telephone transmitter. Operating with a standard SIM card which eliminates the problems associated with wired transmission, it can sequentially transmit 6 vocal and SMS messages to 9 different telephone numbers in 3 separate sequences. Extremely user friendly with its vocal assisted programming menu, it is powered by the mains supply with an automatic signalized battery back-up in case of power failure.
