SEM 7800 Series Magnets

The Sentronic 7800 Series magnet releases when the fire alarm panel enters an alarm condition and the electrical current is interrupted, allowing the Door to perform manually until Power returns. The tri-voltage design provides 35 pounds of holding force. The magnet is fail-safe and will hold the Door until the current is interrupted. The SEM 7800 Series is protected by a 2-year warranty, meets ANSI/BHMA 156.15 and is UL Listed for metal smoke barrier or labeled fire doors. All magnets in the Series feature die-cast housings and are available in aluminum and dark bronze finishes. The SEM 7820 is floor-mounted, the SEM 7830 is surface wall-mounted, the SEM 7840 is low-profile recessed wall-mounted and the SEM 7850 is standard-profile recessed wall-mounted. All magnets but the SEM 7820 are suitable for pocket Door installation.
