mag-lmlk1200-350-free-shipping The FAS Laundromat Magnetic Lock Kit is the perfect kit built specially for Laundromats’. It consists of a magnetic lock, battery backup with power supply, push to exit button, exit motion sensor, on and off key switch, and the very important timer that will automatically close the system at whatever hour you set it to. You will set the timer to open at a pre-determined time giving you the freedom to be away from the establishment and not worry if the system will open or close because the battery backup will keep the system working in the event of a power failure.
