SIMPLE SCHEME OF SECURITY SIGNALING OF THE APARTMENT, HOUSES, GARAGE

When you turn on the voltage of 220 V (S1 is closed), power is supplied to the step-down transformer and the electric siren. The “Alarm on” light comes on and the rectifier starts working. The Alarm light on the alarm console does not light up, because contact P12 is open. Electric siren does not work, because contact P13 is open. In the initial position, all contacts K1, K2, P11, MB1, MB2, etc. open (buttons K1, K2 are not pressed, and gates, doors, windows, etc. are closed). When you press the K1 button on the alarm control panel, power is supplied to the relay P1, which is triggered, self-blocked by contacts P11, and contacts P12, P13 are energized   Alarm light on the alarm console and electric siren (siren sounds). This check indicates the health of the alarm system. When you press the button K2, which is located in the garage, or the opening of gates, doors, windows, etc. The alarm light comes on and a siren sounds. This check indicates the operability of the entire line in the garage and its contacts ( microswitches ) for gates, doors, windows, etc. If, when an alarm is triggered, the thief will again close the gate, door, window, etc., then the alarm will be issued until the voltage of 220 V is removed (S1 is turned off).

The scheme is assembled in a small box (remote), which is located in the house. The wires of the alarm line to the garage should be held discreetly.

S1                           - a switch of any type for 220 volts.

Tr.1                        - step-down transformer for 12-30 c .

D 1 , D2                   - rectifier diodes.

C1                           - electrolytic capacitor at 100-1000 microfarads .

P 1                           - a relay with self-locking contacts and two contacts for closing.

L 1 , L2                    - signal lamps for voltage, which is provided by transformer III winding.

K 1 , K2                    - buttons test the security alarm.

MW 1 , MW2, etc. - microswitches (contactors) on gates, doors, windows, walls (in the garage).

ES                          - electric siren (bell) of any type for 220 volts.
