What it is

The UltraPro Personal Security pack offers a straightforward approach to home monitoring without the complexity of smart hubs or monthly subscriptions. Each unit uses a classic magnetic sensor to trigger a piercing 120-decibel siren the moment a door or window is breached. This makes it an effective deterrent for intruders and a reliable way for parents to monitor toddlers or sleepwalkers moving through the house at night. Installation is remarkably simple, relying on heavy-duty adhesive tape rather than drilling into frames. Each unit features a three-way switch allowing you to toggle between a loud alarm, a gentle chime for retail-style entry alerts, or a complete off setting for when you want to leave windows open. The included LR44 batteries are monitored by a front-facing LED indicator, ensuring you are never caught off guard by a dead unit.

Ravvy AI insight

While marketed as a security system, these are best utilized as 'annunciators' rather than a full smart home replacement. Their primary value lies in the 120dB output which is significantly louder than most integrated smart sirens, making them excellent for secondary perimeter defense in apartments.

How to get the most out of it

Proper Alignment

Ensure the arrow on the main unit and the arrow on the magnetic strip are perfectly aligned within a half-inch of each other. If the gap is too wide, the sensor will think the door is open even when it is closed.

Ownership tips

tip

Surface Preparation

Clean your door and window frames with rubbing alcohol before applying the adhesive tape. This removes oils and dust that can cause the alarms to fall off over time.

care

Battery Maintenance

Test each unit monthly by switching it to chime mode and opening the window. If the LED flickers or the sound is distorted, replace all four LR44 batteries immediately to maintain peak decibel levels.

Frequently asked questions

Can I hear this from another room?

Yes, the 120dB siren is extremely loud and designed to be heard throughout a standard-sized home. It is roughly equivalent to the volume of a nearby chainsaw or power drill.

Does this work with my smartphone?

No, these are standalone 'dumb' devices. They do not connect to Wi-Fi, Bluetooth, or any mobile apps, which means there are no monthly fees but also no remote notifications.

Will these work on sliding glass doors?

Yes, they work on almost any opening that can accommodate the two pieces being close together. As long as the sensor and magnet separate when the door slides, the alarm will trigger.

Are batteries included in the box?

Yes, each of the six units comes with four LR44 button cell batteries pre-installed. You simply need to pull the activation tab to begin using them.
