MAKING 5 ZONE ALARM CONTROL CIRCUITS

Alarm is one security tool for home or small-sized companies. Many types of alarms produced by a variety of inputs, outputs and configurations. In this scientific writing and explain the author makes the analysis or the workings of a series of five zone alarm. This series consists of several blocks, including blocks of regulators, switches zones, buffers, logic and alarm circuit. Experimental results show that the five zone alarm will sound if the switch ON / OFF switch in the On state. Trigger the alarm is an alarm switch and to indicate where the ring is marked with a flame led.
