The AF-MUL (Voice & Remote Unit) extension module allows any Comat BoxX to be controlled remotely over a telephone line. The AF-MUL is called up, and then enabled by entering a password.

In this way you can switch circuits on and off using an ordinary DTMF telephone or a mobile. A voice recording finally confirms the change of status.

The Comat BoxX with AF-MUL can indicate up to 98 pre-defined states, such as alarms, over the telephone line. The voice module has a total memory capacity corresponding up to 8 minutes.

The BoxX can dial pre-programmed telephone numbers and replay recorded text once the connection has successfully been established. This would, for instance, allow an alarm to be transmitted to someone responsible for a plant or to a property security company. There are almost no limits to the possibilities.

The AF-MUL can, however, also be used in combination with an ordinary commercial modem. In this way the program in the BoxX can be monitored, and also of course modified, with the aid of a PC. This offers the ideal facility for remotely servicing an installation.

It is also possible for an external loudspeaker to be connected to the AF-MUL for applications within buildings.

The Comat BoxX and AF-MUL together therefore form the ideal tool for all monitoring and alarm tasks, both in private and in industrial contexts.
