The Murphy Door® battery backup is an option for our Electromagnetic Lock. It is not a stand-alone product.
This battery backup is a necessity to keep your door securely locked when power goes out. The same power that keeps your Electromagnetic Lock, keeps this battery charged for when it is needed. When the power goes out, the power will keep your Electromagnetic Lock functioning for up to 72 hours.
This replaces the standard power supply that is usually shipped with the Electromagnetic Lock.
Murphy Door® recommends a licensed and trained electrician whenever wiring is involved.

FAQ
How many customers has Murphy Door served?
Murphy Door is trusted by over 200,000 customers worldwide.
What warranty does Murphy Door offer?
Murphy Doors carry a Lifetime Warranty on Hardware, Wood, and Workmanship, covering hinges, hardware, structural steel reinforcement, MDF cores, and labor for the lifetime of the original purchaser. Factory finishes (paint, stain, lacquer), mechanical locks, veneer, and plywood face are covered for five years. Electronic locking systems are covered for one year. See full warranty terms at murphydoor.com/pages/warranty.
Does Murphy Door offer white-glove delivery?
Yes — White Glove Delivery, which brings your unit off the truck and into your home (inside delivery, room placement, and packaging removal), is available as a paid add-on starting at $350 (standard) / $550 (overlength). This service is especially popular for Murphy wall beds and large armoire systems where the sheer scale of the panels benefits from professional handling. The White Glove Delivery add-on and its pricing are shown at checkout based on your product. White Glove Delivery covers delivery and inside placement only — it does not include installation. For professional installation, Murphy Door offers a network of licensed contractors in select cities; call 888-458-5911 to check coverage and get a quote.
How do you open a hidden door from the inside — is it safe if someone is locked in?
Safety is built into every Murphy Door design: all units include an interior release mechanism so the room can never become an inadvertent trap. Standard configurations feature an interior handle or touch-latch that opens the door from the concealed side without any special key or code. For safe rooms and panic rooms, we incorporate dedicated interior emergency release hardware that overrides any external locking system. Full safety details are covered in our installation guides, and our support team can specify the right release mechanism for your configuration.

Before You Install: Finish Those Walls First
Surface Mount sits over a fully finished opening: drywall,
paint, and trim done, just like an existing doorway. If
you’re still mid-construction, finish those edges out
first, or the raw sheetrock and framing around the door will
stay visible once it’s mounted.
