The latest version of Fireco's highly successful System X wireless fire safety system uses a System X Wi-Fi transmitter unit (TX), with a 1000m site specific range, that's wired into the fire alarm panel or loop using fire rated cable to monitor the fire alarm panel as well as any linked devices. In the event of a fire alarm or fault the System X Wi-Fi transmitter unit (TX) sends a radio signal to all linked fire safety devices to activate.
