The flexibility of the Micro Interface range means that the units can be used in a range of different applications. The interfaces can be ideal for tall buildings, and act as a connection message to other devices that feedback device status to control panels, and can activate devices.
They can be ideal for use in tall buildings that have extractor fans to filter out any smoke from fire. The output unit will receive feedback from the control panel and can act as a switch to activate a fan when there's a fire. The input unit will then feedback to the panel whether the fan is active or if there are any faults.
