The GE51107 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.

+120-Decibel alarm sounds when window or door is opened
+Easy to install with no wiring necessary
+Door alarm uses 4-digit keypad to set security code for arming/disarming

simple installation. just make sure you play with the window pieces first before actually sticking them on. the window units are actually simplistic - can be turned off or remove, crushed, or thrown away by the intruder. alarm is very loud but can be suffocated with a piece of cloth. so, it works as advertised but may not be effective against sophisticated intruder(s).
