Greater Reliability in Cellular Communications

DualSIM functionality allows one communicator to transmit signals over Verizon and AT&T networks—a feature rapidly growing in demand.

DualSIM products improve the customer experience with increased reliability and fewer service calls. Dealers can choose to activate one provider, or both, eliminating the customary service call needed to change carriers. When both carriers are activated, an improved communication process with additional benefits is enabled:

• The control panel chooses a primary cell carrier based on signal strength.
• Every hour, the panel will check the signal of the primary carrier.
• If the signal strength indicates risk of losing connection, the system checks the secondary carrier’s signal, automatically switching over if its signal is better.
• During alarm transmission, if a signal fails with one carrier, the system will switch to the other carrier to deliver the message to the monitoring center.
