Magnetic hold-opens - Mounted

While power is applied, these devices hold the door open to permit free passage. When triggered, they release, allowing the door to shut. The hold-opens may be linked to a fire alarm system to close automatically in case of emergency, preventing the spread of smoke through the building.
