Window and Door Alarm When Opened (5 Pack) for Kids Safety/Home Security, Sliding Front Door Opening Sensor Alarms for Dementia, 120dB Burglar Alert, Ideal for Business, Garage, Apartment,House, White
Quick take
This 5-pack wire-free door and window alarm set triggers an audible alert when a contact sensor detects an opening, making it a straightforward option for home, apartment, or business entry-point awareness. The 120dB siren mode is designed to be attention-grabbing, and the set button lets you switch behaviors and adjust volume between 90dB and 120dB. The biggest caveat: it is not a smart or remote-controlled system, and it needs two AAA batteries per alarm (not included).
Pros and cons
Pros
- Very loud 120dB audible alarm for clear alerts when a door or window opens.
- Wire-free design with adhesive mounting, quick setup without complicated wiring.
- Selectable volume (90dB or 120dB) and multiple alert modes using the set button.
- Low-battery and trigger indication via a flashing red LED.
Cons
- Requires 2 AAA batteries per alarm, and batteries are not included.
- No remote control support (and not compatible with the remote model mentioned for a different product).
- Not designed to pass UL 2017 pool inspection requirements.
What buyers think
Buyer-review evidence for this alarm set emphasizes three themes: setup ease, alarm volume, and whether the contacts behave reliably. Several reviews call out that the alarms are very easy to install (often described as peel-and-stick) and that the 120dB alert is loud enough to grab attention. Reviewers also report that the sensors detect door or window opening events without frequent, annoying false alarms. Where feedback gets thinner is on long-term durability, since some reviewers note limited time using the product.
How this door and window alarm works
Each unit is a contact-style alarm system, meaning the alarm triggers when the magnetic sensor detects that a door or window has opened. It is designed to run on AAA batteries and uses an on/off switch plus a set button to arm and adjust behavior. An LED indicator flashes red when the alarm is triggered and when the battery is low, so you have a visible prompt in addition to the sound.
Alert strength and modes you can choose
If your goal is basic entry-point awareness, the two loudness levels are a practical feature. You can choose 90dB or 120dB. Beyond volume, the set button supports multiple operating modes, which can help you match the alert type to the situation:
- Door open alarm: siren sounds for about one minute when the door or window opens, with a “SET” action to turn it off.
- Doorbell chime: a “ding dong” sound when the door opens (more subtle than a siren).
- Alarm stop on closing: siren continues until the door closes within a minute, or you press “SET,” with automatic stop if it is not closed.
- Door open reminder: repeating “beep beep” sounds until the door closes or you press “SET.”
This makes the set useful as more than a single-purpose burglar alert, especially when you want reminders or chimes rather than always using the loudest sound.
Installation and placement tips for better detection
The alarm uses adhesive mounting (3M double-sided tape is included), which is one of the reasons people buy contact alarms like this in the first place. The key is proper alignment and spacing between the magnetic components. For best performance, keep the gap between components under about 0.39 inches and ensure the arrows face each other. If you are applying it to a sliding door, position it so it can detect the sliding movement effectively.
Who this is best for
- Apartment or business owners who want quick, simple alerting on entry points without running wires.
- Homes with kids where you want an audible reminder when a door or cabinet area opens.
- Care settings for dementia support, where an alert can help notify you when doors to specific areas are being opened.
- Anyone needing an add-on to supplement existing routines with a loud audible notification.
Who should avoid it
- Buyers who need smart-home or remote control features should look elsewhere, since this system is not smart and does not support remote control.
- Pool inspection compliance needs: it is not intended to meet UL 2017 pool inspection standards.
- Shoppers who do not want to manage batteries may prefer hardwired or rechargeable solutions.
Price and availability
At the time of this review, the set is listed as a 5-pack option for a relatively budget-friendly price point compared with full home security systems. Since it relies on batteries and adhesive installation, it is best seen as a practical alert add-on rather than a replacement for a monitored alarm system.
Verdict
The Window and Door Alarm When Opened 5-pack is a solid choice if you want a simple, wire-free way to get an audible alert when a door or window opens. The combination of adhesive install, adjustable volume (90dB or 120dB), and multiple alert modes makes it flexible for home security awareness and safety-focused setups. Just be sure you do not need remote control or smart features, and plan for AAA batteries.
