SCHEMA DOOR ALARM: ELECTRONIC REALIZATION
AUTOMATED ASSEMBLY DOOR RING:
When the door is open, the device is triggered during a brief period and activates the buzzer is conneetee him.
When the door is closed, the device enters again function by pressing the ring for a few moments. The supply voltage must be 12 Volt DC The maximum consumption is about 70 mA with relay energizes and 3 mA onlyby rest.
To change the relay excitation time (duration of the ring), we must act on the value of the capacity C2. By increasing this value, the time increases and vice versa.
For assembly of components and connections, we must be attentive to the implementation of the scheme indications.
LIST OF ELECTRONIC COMPONENTS: All resistors are 1/4 watt unless otherwise noted. R = 4,7Kohms R2 = 33Kohms Cl = 10uF16Velec. C2 = 470uF16Velec. IC1 = 40106B RL = 2V relay 1 magnetic reed switch 1 Support 14 pin
