The GE Personal Security Alarm Kit includes everything you need to help secure your home, including a deluxe door alarm with a four-digit keypad and three independent window alarms. Best of all, there's no wiring or drilling required for installation. This simple-to-use, cost-effective security solution helps protect you and your family against home invasions thanks to each of the 120-decibel alarms, loud enough to make a would-be intruder think twice about entering through your doors or windows. The GE Personal Security Alarm Kit couldn't be any easier to install. Simply mount the deluxe door alarm and any of the window alarms using either double-sided tape or screws (included). Next, check that the batteries are fresh using the battery test switch or low battery indicator. It's that easy! There's no wiring involved, so the kit is simple for anyone to install. The system is also extremely easy to use. The door and window alarms feature a contemporary design with easy access buttons and controls for simple operation. This straightforward concept makes using the alarm kit intuitive, no matter what your technological skills may be. The deluxe door alarm features a four-digit keypad for programming your custom pin, to secure any door in your home. The unit mounts easily with the included mounting plate. No measuring or messing with templates. Using the included double-side tape or screws, simply attach the mounting plate in the desired location and snap the door alarm into place–it's that simple. And best of all it requires no wiring. Using the deluxe door alarm is a breeze. You can select instant or delayed alarms with the flip of an easy-access switch. In the 'Away' mode, you have 45 seconds to exit your home after you arm the system. When you get back home, simply open the door and deactivate the alarm within 30 seconds by entering your custom four-digit code. The 30-second delay helps to eliminate false triggering of the alarm. When you're home, simply select 'Home' mode for an instant alarm. With a 120-decibel siren, the alarm is loud enough to alert you or your neighbors of a possible break-in. The siren is sure to scare any intruder, and will give you plenty of warning to alert the authorities and get your family to safety. When not in 'Alarm' mode, all the alarms in the Alarm Kit offer a chime setting that alerts each time a door is opened. This is a great safety feature if you have small children that may make their way outside unsupervised. The GEPersonal Security Alarm Kit also includes three independent window alarms, each with a built-in 120-decibel alarm for even greater home security. With no wires required for installation, protecting any window in your home is as easy as attaching the window alarm to your window with screws or double-sided tape (included). Each window alarm features an on/off/chime switch for easy operation and a battery-test switch for checking battery life. Each alarm requires four LR44 batteries (included) that last up to a year. Perfect for homes, apartments, dorm rooms and offices.
