Abstract

PURPOSE: To prevent erroneous alarms which may be given at a time other than when the power stops by allowing FF to memorize the fact that the power is supplied to the transmission line once and giving an alarm by a buzzer, etc. only when there is power failure.
CONSTITUTION: Plug 111 is inserted into the plug receptacle provided on the transmission-distribution line subject to detection of power failure and A/C input supplied through plug 111 is rectified and smoothed 112 and after it is inputted to and rejected by FF115 at the samt time, it is inputted to AND circuit 116. Therefore, when power supply to plug 11 is shut-off after A/C power is supplied to plug 111 and FF115 is set, the output of AND circuit 116 becomes "H", transistor 118 is turned on and buzzer 17 sounds for alarm. With this invention, this unit memorizes that the power is supplied to the transmission line once and gives alarm by a buzzer, etc. only when the power actually stops, thus preventing erroneous alarms that may be given when there is no power failure.
