The FirePro-V4 has been specially developed for use on industrial Fail-Safe drives (230V or 400V) with digital or mechanical limit switches, a centrifugal brake for controlled closing in the event of a fire alarm and a 24V brake to keep the door in position during normal operation. The FirePro-V4 is equipped with a signalling device (sound + flashing light) that is powered via the unique P-CAP system. This system is guaranteed to emit a warning signal for up to 2 minutes after the loss of all power (mains and battery voltage). The complete menu can be easily set using 3 buttons and the display on the printed circuit board. Simply select the desired parameter and set the functions as desired. Thanks to a specially designed control cable, which is available in various lengths and is equipped with plugs, it is very easy to connect the FirePro-V4 to a Fail Safe drive with digital or mechanical limit switches.
