The "Disaster Prevention Equipment Electromagnetic Release 'Magnet Door Holder' LCN 7840/7850" is a robust, electrically controlled electromagnetic door holding device. It complies with building codes and can legally hold fire doors open. When used in conjunction with a door closer, the door will automatically close when the power to the magnet is cut off. Even if the wiring is broken or melts in a fire, it can reliably close the door, and there is no concern about false alarms due to erroneous activation of the alarm system, allowing for safe use. 【Features】 ■ The magnet remains open during a power outage and holds until the current is cut off. ■ Legally holds open a normally closed fire door (15kg). ■ Constantly powered, linked to smoke detectors = power outage during a fire. ■ No false alarms when pulled away (no status signal). ■ Works in conjunction with the power supply (feedback to the disaster prevention panel). *For more details, please refer to the PDF document or feel free to contact us.
