What Is a Wireless Window Alarm?
A wireless window alarm is a battery-operated security device that uses a magnetic sensor to detect when a window is opened. The GE 45115 is a prime example of a magnetic window alarm that doesn’t require any wiring or professional installation. Simply stick the main unit and the magnet on the window frame using the included double-sided tape. When the window is opened, the magnet separates from the sensor, triggering either a loud 120-decibel alarm or a chime—depending on the mode you select.
This type of door window chime is also useful for alerting you when children or pets open doors. The versatility of having both an alarm and a chime mode makes this product a great choice for various home security needs.
Key Features of the GE 45115 Wireless Magnetic Window Alarms
120-Decibel Intruder Alert
The GE 45115 produces a piercing 120 dB siren that is loud enough to scare off intruders and alert everyone in the home. This is a critical feature for any home security alarm because the loud noise alone can deter a break-in before it escalates. We tested the sound level and it’s genuinely startling—perfect for drawing immediate attention.
Three Modes: Chime, Off, and Alarm
One of the most user-friendly aspects of this window alarm is the simple side switch. You can choose between three settings: OFF (disabled), CHIME (plays a pleasant tone when opened), and ALARM (activates the full 120 dB siren). The chime mode is ideal for monitoring children’s rooms or back doors without setting off a panic alarm every time someone enters.
Battery Operated with Low Battery Indicator
Each unit runs on four included LR44 button batteries. The battery test button and low battery indicator LED let you know when it’s time for a replacement. Being battery operated means you can place these alarms anywhere without worrying about nearby power outlets or extension cords.
Wireless and Tool-Free Installation
Installation takes under a minute. The package includes double-sided adhesive tape, so you simply peel and stick the alarm unit and magnet onto the window frame. No drilling, no screws, no wires. This makes the GE 45115 an excellent easy install alarm for renters or anyone who wants a quick security upgrade.
Comes in a 2-Pack
You get two complete alarm systems in one box, which is great for covering both a front window and a back door. If you need more, you can buy multiple packs to secure every entry point in your home.
How Does a Magnetic Window Alarm Work?
The GE 45115 uses a magnetic reed switch. The main alarm unit contains the electronics and the sounder, while a separate small magnet is placed next to it on the window. When the window is closed, the magnet holds a switch inside the unit in the “closed” position. When the window opens, the magnet moves away, the switch opens, and the alarm sounds (or chimes) based on your setting.
This wireless magnetic sensor technology is extremely reliable and requires no calibration. It’s the same principle used in many professional security systems but at a fraction of the cost.

Where to Use a Window Alarm at Home
These window security alarms are ideal for ground-floor windows, sliding glass doors, and even the door to your garage or basement. They work on both hinged windows and sliding tracks. Many homeowners also use them on doors leading to a patio or balcony. Because the chime mode is discreet, the GE 45115 is popular among parents who want to know when toddlers open a door. It’s also a great addition to an apartment where you can’t permanently alter the structure.
Installation and Setup Guide
Step 1: Remove the battery tab to activate the unit. Press the test button to confirm the LED lights up. Step 2: Clean the window frame area where you’ll attach the alarm. Step 3: Peel the backing from the double-sided tape and stick the main unit to the frame. Step 4: Align the magnet piece next to the unit (within 1/2 inch).

Frequently Asked Questions (FAQ)
Do window alarms really deter burglars?
Yes, a loud intruder alert system makes a burglar think twice. The sudden 120 dB noise draws attention and forces them to retreat. Even a simple window alarm can be enough to make your home less appealing than a neighbor’s.
Can I use the GE 45115 on a door?
Absolutely. It works on any door or window where a gap exists between the magnet and the sensor when opened. It’s great for interior doors, cabinets (for childproofing), and pet doors.
Are these alarms waterproof?
No, these units are designed for indoor use only. They should not be placed directly in the rain or high humidity areas like a bathroom without ventilation.
How long do the batteries last?
Battery life depends on usage. In alarm mode, the siren will drain faster, but in chime mode, they can last several months. The low battery indicator helps you stay ahead.
Can I connect this alarm to my smart home system?
The GE 45115 is a standalone device. It does not have WiFi, Bluetooth, or Z-Wave. If you want a smart door alarm sensor that integrates with Alexa or Google, you’ll need a different product. However, this simplicity is a strength for those who want something that just works.
