The FireRoll-24V has been specially developed for fire-resistant roller blinds with a 24V tubular motor with mechanical limit switches. In the event of a fire alarm, the roller blind can be opened or closed. If the mains power supply is not available, the built-in batteries with charging unit provide the necessary power so that the roller blind can still be opened or closed. The FireRoll-24V is equipped with an output for external signalling (sound and flashing light). The complete menu can be easily set using a rotary/push button and the display on the printed circuit board. Simply select the desired parameter and set the functions as desired. The integrated RS485 connector offers the possibility to easily expand the FireRoll-24V with optional modules such as an I/O module with 2 programmable inputs and 4 programmable outputs.
