One transponder can monitor a maximum of 30 wireless devices.   List of compatible units: - wireless detector base (conventional detectors), - wireless manual call point, - wireless I/O module, - wireless sounder.

The transponder operates in addressable mode, so it transmits the alarm message of any wireless sensor or wireless manual center in an identifiable (addressable) way to the fire alarm center.

The transponder simulates the status changes of the wireless sensors on the addressable loop by creating the messages corresponding to the addresses.
Due to the two-way wireless connection the transponder is able to send command messages to the wireless devices.

The system operates at 868MHz, which is a free frequency in the European Union.

The operating range of the devices meets all requirements. In practice, a transponder installed in the center of a building can operate in a range of four floors up and down, as well as 100 meters horizontally in buildings with concrete base and brick structure.

A field strength measuring device can be used for checking the operating range of the devices to be applied.

Windows-compatible editing software should be used for installation; it identifies the transponders and the assigned wireless units. Each wireless unit uses a custom barcode ID alongside a three-digit optional address via which can be downloaded from the transponder during installation. The software of the operating system is suitable for displaying the field strength of the devices and the battery voltage, as well.

The transponder receives the voltage necessary for its operation from the addressable or the collective loops.
