UltraPro Window and Door Alarm 12-Pack — Wireless 120dB

UltraPro Personal Security Window and Door Alarm is a pack of twelve compact, battery-powered magnetic sensors that instantly sound a 120 dB alert when a door, window, cabinet or drawer is opened.

If you want a fast, no-hassle way to add audible protection to multiple entry points without wiring, apps, subscriptions or professional installation, this 12-pack gives broad coverage right out of the box. Each unit ships with four LR44 batteries installed, a magnet block, and double-sided tape for tool-free mounting. Choose between a gentle chime for routine monitoring and a loud siren to deter intruders, and rely on the front LED low-battery indicator for timely battery changes.

How does the UltraPro alarm alert me when a door or window opens?

Each alarm uses a magnetic reed sensor: when the magnet separates from the alarm base because a door, window or drawer opens, the device immediately sounds. You can switch between a soft chime mode for frequent entries and a high-volume siren to draw attention during unauthorized access.

• 120 dB siren to discourage intruders and attract attention
• Chime mode for everyday monitoring without startling household members
• Magnet and base trigger on separation — no wiring required
• Front LED indicates low battery so you won’t be caught off guard

How easy is installation and placement around the home?

Installation is tool-free and takes only minutes using the included double-sided tape; peel and stick the alarm base and magnet in aligned positions on the frame and sash. The compact, lightweight design lets you place alarms on doors, windows, cabinets, drawers, garages, RVs and more where quick awareness is needed.

• Peel-and-stick mounting requires no drilling or screws
• Compact footprint fits small frames and tight cabinet edges
• Battery-powered for flexible placement without outlets
• 12-pack covers multiple rooms or access points immediately

What maintenance or battery care does the UltraPro alarm need?

The alarms operate on four LR44 batteries included for instant use and a front LED warns when battery levels drop. Replacing batteries is straightforward; because the units are inexpensive and compact, regular checks keep them ready for long-term use without professional service.

• Ships with LR44 batteries pre-installed for out-of-box operation
• Visible LED low-battery indicator on the front panel
• Quick battery swap extends service life—no tools needed for access
• No app or cloud dependency means no firmware updates required

Where does this alarm work best and what will it not replace?

These alarms are ideal for boosting awareness at interior and secondary entry points like windows, patio doors, garage doors, cabinets, dorm rooms, RVs and offices. They are an excellent deterrent and alert device, but they are not a replacement for full professional alarm systems with monitoring, remote alerts, or integrated home automation features.

• Perfect as supplementary protection for multi-point coverage
• Useful in rentals or temporary living spaces where permanent wiring isn’t allowed
• Not a substitute for monitored systems that contact emergency services
• Great for quick deployment in travel, storage, or vacation properties

Who is this for? Homeowners, renters, college students, small-business operators and travelers who want a low-cost, immediate audible alert system will benefit from the UltraPro 12-pack. It suits anyone seeking a simple, wireless way to notice openings of doors, windows or cabinets without monthly fees, complex setups or permanent installations. Use it where you need instant sound-based awareness — from apartments and houses to RVs, dorms and offices — and enjoy straightforward DIY protection backed by recognizable 120 dB deterrence.
