Abstract
An alarm system providing programmable remote control of electrically controlled devices, such as lights, is provided. Geographic site and date information is provided to the alarm system. The parameters used to dictate the activation and deactivation of the controlled devices include the geographic site location and the sunrise and sunset times for the current date at that site. Accordingly, the activation and deactivation times of the controlled devices be programmed to automatically track the shifting sunset and sunrise times at the site.
