Principles of operation

Communicator GT7 receives data from:

• Common bus:
• Compatible with: DSC® PC585, PC1565, PC5020, PC1616, PC1832, PC1864.
  PYRONIX® MATRIX 424, MATRIX 832, MATRIX 832+, MATRIX 6, MATRIX 816.
  GE® CADDX NX-4, NX-6, NX-8.
• Serial output:
• Compatible with: PARADOX® SPECTRA SP5500, SP6000, SP7000, 1727, 1728, 1738.
  PARADOX® MAGELLAN MG5000, MG5050.
  PARADOX® DIGIPLEX EVO48, EVO192, NE96, EVO96.
  PARADOX® ESPRIT E55, 728ULT, 738ULT.
• Telephonic communicator i.e. control panel transfers data to GT7 communicator through C11 interface or C14 interface.
• Outputs (PGMs), .e. communicator transfers signal regarding the change of input state, having received it through
  input expander CZ6.

The GT7 can be connected to the serial output or common BUS of compatible control panel directly for actual event report reception.

If alarm panel is not supported by GT7 via serial output or common BUS, additional 6 zone Expansion Module or Contact ID module can be used instead.

Security module GT7 sends information, received from the control panel, to monitoring station by either GPRS or CSD or SMS. If the connection has failed, communicator will repeatedly attempt to restore it for n times (number of attempts (n) can be set). If the module GT7 fails to restore connection, the module will automatically connect to the back-up channel and send the unsent messages through it. Duration of connection or attempts to connect to the back-up channel can be set, after which the communicator tries again to connect to the primary channel.

Security module GT7 sends signals PING for testing of communication. Messages sent to monitoring station correspond to Contact ID table of codes.

Message receivers:

• Software based IP receiver AGSR (Alarm GSM Signals Receiver). Free AGSR receiver software available to operate with practically any central station software. This software is designed to convert data received via GPRS to serial RS232 or Ethernet TCP/IP . The software emulates Surgard MLR2-DG. This is free software and available with purchase of GT7 module. Please contact us at by mail for software.
• Hardware based receiver Linux AGSR10.

Module can transform the data, received from the security panel, to text SMS messages and send them up to 4 mobile phones. Text of SMS message (name of object, user names, partitions names, event descriptions) can be specified by the User.
