Various electronics modules are available for mounting options 1 and 2 (integrated or remote electronics). Additionally, there are electronics modules with integrated surface sensing with which front plates can be made touch-sensitive for guard alerts etc. As an alternative to the EF 031 series of front plates, analogue intercom modules can be connected. This allows for custom front plate design. Please note: Electronics modules and flush mount boxes need to be ordered separately.

This module detects mobile phone/modem connections using UMTS and GSM networks and are user friendly in terms of installation – plug & play. Depending on the structural conditions of the building, the modules detect a connection within a 20 meter radius. As soon as anyone attempts to make a mobile call, send a text message, or use an internet connection, an alarm is triggered at the station or control desk within the complex on the Commend intercom system. The connections can be located with the aid of the identifi cation number or name of the active module on the display screen. A visual indication, in the form of a lamp for example, is also possible.

Build-in module for detecting mobile phone/modem connections, consisting of an antenna, a high frequency and a signal section. The module is equipped with a potential free relay output (break contact) and is enabled for data transfer via the RS 485 port. Installable in EF031-xxR series front panels of detention cell terminals. Typical applications: Prisons, arrest and detention centres in police ...
