SIMPLE SCHEME OF SECURITY SIGNALING OF APARTMENTS, COTTAGES, GARAGES

When the 220 V voltage is turned on (S1 is closed), the transformer and the electric siren are energized. The "Alarm on" light comes on and the rectifier starts working. The "Alarm" light on the alarm panel does not light, because Contact P12 is open. The electric siren does not work. 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). Pressing the button K1 on the alarm panel energizes the relay P1, which is activated, self- blocked by the contacts P11, and contacts P12, P13 supply power to the   Light bulb "Alarm" on the alarm panel and electric siren (siren sounds). This test indicates the operability of the alarm panel. By pressing the K2 button, which is located in the garage, or opening the gate, doors, windows, etc. The "Alarm" light comes on and the siren sounds. This test indicates the operability of the entire line in the garage and its contacts ( microswitches ) of gates, doors, windows, etc. If the thief again closes the gate, door, window, etc., when the alarm is triggered, the alarm will come on until the voltage is removed 220 V (off S1).

The circuit is assembled in a small box (console), which is located in the house. The wires of the alarm line in the garage must be held covertly.

S1                           - switch of any type for 220 v .

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

D 1 , D 2                   Rectifying diodes.

C1                           - Electrolytic capacitor per 100-1000 mkf.

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

L 1 , L 2                    - signal lamps for voltage, which provides III winding transformer.

K 1 , K 2                    - buttons for checking the operability of the alarm.

MB 1 , MB 2 , etc. - Microswitches (closers) on the gates, doors, windows, walls (in the garage).

EC                          - electric siren (bell) of any type for 220 v .
