Abstract
A door operator is disclosed which has a motor connected to open and close a door; for example, a garage door and a lamp is provided to illuminate the interior of the garage. Motor and lamp energization circuits are provided as controlled by switches; for example, a push button switch or a radio controlled switch. An alarm circuit is provided which may be a security alarm; for example, a burglar alarm or fire alarm. The alarm circuit is enabled when the door operator is not being used and the alarm circuit is disabled automatically whenever the door operator is being used. A time delay means is provided to maintain the lamp energized for a time delay period after the door has closed, and while the lamp is energized the alarm circuit is disabled, but as soon as the lamp is extinguished then the alarm circuit is enabled or armed.
