The invention relates to signaling and can be used in secret departments of enterprises and organizations for remotely controlling the issuance of documents in a special vehicle to subscribers, for remote opening of special cards and special rooms with the help of coded commands, and for centralized monitoring of safe opening, subscriber premises.

The purpose of the invention is to ensure reliable operation of the device.

In the drawing of FIG. 1 a and FIG. 16 shows the electrical circuit of the device.

The device contains a coding unit with dialer 1, step searchers 2, 3, relay 4, with two closing contacts 5, 6 and one normally closed contact 7, relay 8 with two closing contacts 9,10 and one normally open contact 11, relay 12 with two closing contacts 13, 14 and one normally closed contact 15, a relay 16 with two closing contacts 17, 18 and one normally open contact 19, a relay 20 with two closing contacts 21, 22 and one normally open contact 23, a relay 24 with closing contact 25 and a disconnecting contact 26, relay 27 with normally open contact ohm 28, relay 29 with two closing contacts 30, 31, relay 32 with two closing contacts 33, 34, relay 35 with closing contact 36 and opening contact 37, relay 38 with opening contact 39 and two closing contacts 40, 41, relay 42 with opening contact 43, capacitor 44, with two groups of dissociating dioo

45, 46, a remote control unit consisting of switches 47, buttons 48, microswitch 49, signal lamps 50-53, group of isolating diodes 54, contact groups 55, 56, relay 57 with a break contact 58, A set of test electromagnets contains relay group 59, valve group 60, button group 61.

The device works as follows. Switch 47 is set in position. At the same time, the positive bus is fed through the disconnecting contact 37 of the relay 35, and the voltage is supplied through the disconnecting contacts of the dialer 1 to the windings of the relay 27 and 29. The relay 27 breaks the disconnecting circuit 28 of the stepper finder 2 and the relay 29 applies voltage to the preparation bus of the step finder 2 and the closing contact 34 prepare the relay coil circuit 38.

When dialing a dial-up dialer 1, its switching group is activated. The next first stroke of the dial disc breaks its opening group the number of times, corresponding to the number dialed on it. Each break of this group de-energizes the winding of the relay 27 and closes the contact 28, applying current to the winding of the step finder 2. The slider of the latter moves one step, and in just the first working stroke of the dial the same number of steps. When the dial dial returns to its original position, its switching group also returns to the initial state and supplies current to the winding of relay 29. The closing contact 30 of relay 29 supplies current through the Power line to the bus finder 2, corresponding to the first code bit, from which the current falls on winding one of the relays 4,8,12,16,20 and 24 (depending on the dialed digit). The relay is blocked by the corresponding own closing contact to power from the positive bus, breaks the relay coil circuit with the opening contacts 7,11, 15, 19,23 and supplies current through the closing contacts 6, 10, 14, 18, 22 and 26 to the bus finder 2, corresponding to the second bit of the code. At the same time, the current through the disconnecting diodes 46 is supplied to the signal lamp 53 A set that is lit before the accumulated stroke is reset.

During the second reset of the dial, the switching of its contact groups and relays 27 and 29 occurs in the same way as in the previous case, and during the second run, the slider of the step finder 2 advances by the number of steps corresponding to the number of the second digit of the code, and with the corresponding

The lamellae of the second-discharge stator group are applied to the windings of the desired group of actuating electromagnets by a positive voltage. When the engine passes the first stator lamella in the group of the second

0 discharge current through the isolation diodes 45 is applied to the winding of the relay 32, which is detected by its own closing contact 33 for power supply from the positive bus and the closing contact 34 prepares

5 relay circuit 38. Upon the arrival of the dial disk after the second stroke to the initial position, relay 29 through the closing contact 31 supplies current to the relay 38. The latter is blocked with its closing contact 41

0 to power from the plus bus, breaks the power line of the winding of the stepper finder 2 with the break contact 39 and prepares the power line of the winding of the stepper finder 3 with the closing contact 41.

5 At the same time, a positive voltage is applied to the winding of the relay 42.

During the third cocking of the dial, the cycle repeats in the same order, however, the pulses are no longer sent to the stepper finder 2, but through the opening contact 43 of relay 42 to the winding of the steamer 3, the slider of which also moves by the number of steps yes code.

5 In this case, the negative polarity voltage is applied to the line of the third digit of the code, to which the ends of the windings of the executive electromagnets are connected (one from each group) through

0 isolating valves and normally open buttons.

Pressing the button of the corresponding special cabinet by the subscriber triggers the actuating electromagnet, and

5 the door is opened or the lock is unlocked. At the same time, the closure group of the electromagnetic mechanism closes and supplies current to the winding of the relay 35. The opening contact 37 of this relay closes, removes power from the positive bus, and the device returns to its original state. The closing contact 36 of this relay supplies current to the reset buses of the step finders 2 and 3, which also come in

5 starting position.

When the door of the special cabinet is open, the contact group 55 supplies current to the signal lamp 51, which is lit until the door is closed. After it is closed, the rocker actuator is supported by a lock.

Contact group 55 opens and lamp 51 goes out.

In the case of special documents in the cabinet, the opening group of the microswitch 49 opens, and the closing group closes. In this case, the signal lamp 50 is on. When the contents are removed from the cabinet, the corresponding microswitch returns to its original position, the lamp 50 goes out and the lamp 52 lights up. Simultaneously, the opening contact 58 of the relay 57 breaks the winding circuit of the step finder 2. The subsequent dialing is impossible until the inspector places the subscriber control token in a special cell, thus opening the contact group 30, thus extinguishing the signal lamp and unlocking the dialing circuit.

Returning the circuit to its original position in the process of dialing is carried out by setting switch 47 to the Reset position. When this happens the same operations as when the relay 35 is triggered.

If it is necessary to quickly open all cabinets, switch 47 is set to the Reset position and press

button 48. A positive voltage is applied through decoupling diodes 54 to all groups of actuating electromagnets and to the winding of the step finder 3, which, by sliding the slider all contact groups alternately (to avoid overloading the power supply), supplies current to the negative lines. The actuating electromagnets are triggered for a short time (several seconds).
