The SSM modems connected to the communication interface of the Foxtrot basic module will provide communication between the Foxtrot system and the user, e.g. by sending alarm information (ESS - intruders, fire hazards, power failure, flooding the boiler room, etc.), or sending status information. On the other hand, the modems are also capable of controlling the system by text messages: the users can turn on the heating before arriving home, activate the ESS system remotely after leaving home (if they have forgotten to do so) etc.
The UC-1205 is supplied by default.
However, modems manufactured by other companies can also be used for text communication, e.g. the INSYS modems. When using modems that are compatible with conventionally-supported modems, users can take advantage of support for processing SMS text messages and communicating the Foxtrot system with the modem, which is available in the Mosaic environment and the Foxtrot systems. If users wish to use modems with incompatible communication, the operation software must be provided by the Foxtrot system application programme.
GSM modems are usually fitted with a connector (typically SMA) for connecting an external antenna. Antennas are available in many versions, which differ in size, gain, mounting possibilities, placement and design.. Basic types of antennas supplied are listed in Chapter 9.5.3.
