Concept GSM Modem Rev.1.1
The GSM Modem is used in conjuction with Model 3000/Access 4000 systems to provide a pathway for alarm transmissions via the GSM network and to provide SMS control functions and SMS reporting.
Connection is via RS232 cable (included) to an available UART port.
The UART Interface (4port UART 993068; 2port UART 9906066; 1port UART 996065) is purchased separately.
When the system sends text alarm messages to a nominated GSM Mobile phone, the message has a validity period of 168 hours (1 week). i.e. The message will be discarded by the network if not received by the nominated Mobile phone within 168 hours.
