The Wireless Input/Output module is compatible with collective or addressable transponders. In collective mode, if the input of the transponder is activated, the outputs of all the input/output modules will also be activated due to the control signal transmitted by the transponder.  The output of the   Wireless Input/Output module is active as long as the input of the transponder is kept active. The Wireless Input/Output module has a monitored input, as well; its status is transmitted to the transponder. The contact output of the transponder is operated in parallel to the status of the Wireless Input/Output module.  This enables assigning an acknowledgment button or an emergency button to the system.

In addressable mode the transponder simulates the status of the I/O module and transmits it to the fire panel via the addressable signal loop. In this mode, each wireless I/O unit is programmable in the same way as any wired Input/Output module.

In fully monitored and active state, the Wireless Input/Output module transfers the input power supply.

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.
