Wire Break Alarm with Delay
The kit wire-break alarm with delay activates
after a delay of 15 to 30 seconds. When the
thin-wire loop running across the entrance door
is broken, the alarm sounds after a delay of 15
to 30 seconds, the time period set through
variable resistance. Thus the occupants get
sufficient time to lock the room from the outside
and catch the thief. The circuit uses CD4060,
which is a 14-stage ripple-carry binary
counter/divider and oscillator. To Know more,
