Cellular Communications Center - Works with ALL Alarms

Now your alarm system can call out using your existing cellular account. The C3 Cellular Communications Center is a wireless cellular communicator that allows phone calls to be made over the GSM cellular network using the existing telephones in your home. The C3 can be used when there is no landline in your home or the landline is temporarily unavailable. Just add a SIM Card from you cell provider and you are good to go.

Use with security systems
The C3 allows any existing security panel to communicate alarm conditions using the GSM cellular network. The C3 checks the status of the existing telephone line and if it is unavailable, the C3 will emulate the line signal to the security panel. When an alarm occurs, the security panel will dial out using the GSM cellular network to communicate with the central monitoring station or call you as programmed.

Everyday use
When the C3 is connected to the GSM cellular network, attached telephones can be used to make calls. If a landline is present, you will hear the normal dial tone and you can make your call as normal using the landline service. However, if the landline is currently unavailable, you will hear a different tone which indicates the C3 is in cellular mode and the call will be made using the cellular network. If the landline is available, but you still want to make the call using the cellular network, when you pick up the phone and hear the normal dial tone, press the key on the phone and the C3 will switch to GSM mode. At that point, you will hear the cellular mode tone and you can make the call using the GSM cellular network.

When a call is made to the phone number assigned to the GSM SIM card that is installed in the C3, any phones that are connected to the C3 will ring as they normally would when a landline call is received.

Requirements
The HAI C3 requires a GSM SIM card and cellular service. The major GSM players in the United States are AT&T, T-Mobile, and prepaid carriers. Customers with existing GSM accounts can add a line to their cellular account for a reasonable charge and plug the added phone SIM into the HAI C3.
