    Electromagnetic timed door hold which operates independently of the existing fire alarm system. Holds doors open for up to 57 seconds, preventing loss of energy and heat.

    – Works in conjunction with existing door closer, holding single doors or pairs of doors open magnetically- Prevents buckling and distortion to the door – a common problem with permanent door holding systems
    – Ideal for hospitals, residential homes, offices, computer suites, hotels and warehouses
    – Can also be configured to hold doors open until someone has passed through them – ideal for the blind or visually impaired

    Both the MH24 (24 Volt) and the MH240 (240 Volt) units are mounted in a powder coated steel casing
    with brushed stainless steel front covers. The armature plate is mounted on a plastic back plate with a
    flexible ring.
    The armature plates are made of a special metal and designed to release easily when power is
    removed. NO magnet sticking.
    Both MH24 and MH240 can be wired to any type of fire alarm system with the correct voltage.
    MH24 can also be used with the Envirohold Timed Door Hold System, which does not require wiring to
    a fire alarm system, for holding doors open for up to 57 seconds.
    Should the fire alarm system be unable to take anymore load, Envirograf® can supply a 240 volt to 24
    volt control unit to control up to 2 magnets.
    Where doors are far away from a wall, Envirograf® manufacture a metal plate to go by the architrave to
    mount the magnet box onto; finished in white or brown.
