Simple Two-Pack Window Alarm

The UltraPro 45115 kit contains two wireless magnetic alarms that sound at 120 decibels when a door or window opens. Each unit offers an OFF, chime or alarm setting selected by a side switch. The package includes four LR44 button batteries per alarm and double-sided tape for mounting. It is intended for indoor use on windows, doors, cabinets or drawers in homes, apartments, dorm rooms, offices, RVs or campers.

Magnetic Contact Limits

The alarm triggers only when the magnetic sensor separates from its base, so it detects opening but not glass breakage or vibration. A 120-decibel output is loud enough to alert occupants and deter intruders, yet it will not notify a monitoring centre or smartphone. Battery life depends on how often the chime or alarm sounds, and the low-battery LED is the only on-device power warning. Units must stay indoors because the electronics are not weather-sealed.

Tape Mounting and Battery Care

Peel the backing from the supplied double-sided tape, press the alarm base to the frame and the magnet to the moving sash, aligning the two arrows within a few millimetres. Misalignment is the most common reason the chime fails to sound or the alarm false-triggers. Test the switch positions after mounting and press the battery test button weekly; replace all four LR44 cells when the LED indicates low power.

Questions about this item

Should I buy one 2-pack or the 12-pack option for my windows?

The product is sold as a 2-pack; the 12-pack reference appears in a sports-team specification and is not a purchase option for this listing.

How loud is the 120-decibel alarm inside a typical room?

At 120 decibels the siren is extremely loud and intended to startle an intruder and alert anyone indoors immediately.

Does the magnetic sensor use Wi-Fi or Bluetooth to trigger the alarm?

No wireless protocol is used; the alarm triggers mechanically when the magnet separates from the base unit.
