Part of the GE Choice Alert Wireless Alarm System
The GE 45142 Wireless Control Center Starter Kit is the primary component of the GE Choice Alert Wireless Alarm System line of products. Cost-effective and easy to install, Choice Alert components offer wireless operation, multi-zone coverage, home and away settings, and expandability for complete home protection.

With wireless capabilities, Choice Alert products require no complicated wiring, drilling or expensive installation costs. And because they are designed to be part of a self-contained system, there are no monthly usage charges. System components are simple enough for anyone to use, and they can be combined to provide a customized blanket of protection over your entire property.

Wireless Control Center for Sensor Monitoring
The entire Choice Alert Security System is designed around the Wireless Control Center, the system's hub. The Control Center monitors each and every sensor that is wirelessly connected to it. As many as four sensors can be programmed in each of four zones, giving you the security of up to 16 sensors to guard your entire home, including sensors for doors, windows, gates, water leaks, and motion detection.

The Wireless Control Center allows you to secure your system with a custom four-digit code that can be changed at any time. Plus, the center lets you control many system features. For example, you can select 'Home' mode for an instant alarm and 'Away' mode for a delayed alarm. In addition to the armed alarm system, the Control Center also offers a visible and audible Zone Notification alert system (with a choice of continuous alert or single chime mode) and a dedicated alert zone (Zone 4). The center wirelessly transmits and receives signals up to 150 feet.

Additionally, the Wireless Control Center features a low-battery indicator that will alert you when battery power is low in a specific zone, so you'll know exactly when to replace the batteries in every one of your components.

Combine Components for Total Home Coverage
There are several components available for use with the Wireless Control Center, including a door/window sensor, motion detector, water leak sensor, secondary audio alarm siren, signal repeater (for enhanced wireless range), garage door sensor, and Silent Alert LED indicator.. Add up to 16 sensors and give yourself the peace of mind that only complete home protection can provide.

Quick and Easy Pairing With Choice Alert Sensors
The Wireless Control Center features a dedicated "Learn" button that lets you easily pair Choice Alert Sensors within a matter of seconds. The process for disabling sensors is just as simple, making for hassle-free customization of your Choice Alert Security system. There's also a dedicated switch for toggling between 'Alert', 'Chime', and 'Off' modes (affects Zones One, Two, and Three only).

The Control Center includes a special dedicated alert zone (Zone 4) that is always monitored, regardless of the alarm settings. This is ideal for alerting you of water leaks, and open garage, shed, freezer, or medicine-cabinet doors--areas of your home that you want to continually monitor with a silent alarm.

All-Weather Door/Window Sensor that Installs Within Minutes
Installing the Door/Window Sensor couldn't be any easier. Using the included double-sided tape or screws and mounting plate, the sensor mounts to most doors (interior and exterior), gates, or windows within minutes. There's no wiring involved--the sensor transmits alerts wirelessly to the Choice Alert Wireless Control Center within a range of 150 feet.

The Choice Alert Door/Window Sensor can be paired with any of the Wireless Control Center's four zones, and pairing takes just seconds. Zones One, Two, and Three provide alarm protection, while Zone Four is a dedicated alert zone that generates a visual alert along with a continuous beep to discreetly warn you when the zone has been compromised.

The GE Choice Alert Wireless Control Center and Door/Window Sensor are backed by one-year limited warranties.

Wireless installation means less waiting around and minimal compromise to the home structure.Security Without CompromiseAlexor is a wireless control panel, the virtual brain of the security suite. Because it is a distributed system, the panel is not attached to the keypad physically, but rather wirelessly. Designed for flexible, secure installation locations within the home, as long as there is access to AC power, Alexor operates via up to four wire-free keypads (the WT5500). If the system changes its armed state or a wireless device is tampered with, Alexor will immediately be signaled and the appropriate transmission will instantly be transmitted to the monitoring station.
