Description

NEGOTIATING - LOCKING ENTRANCE

The device relates to the field of housing and communal services and can be used to protect residential or industrial buildings from unauthorized entry of unauthorized persons into them.

Known devices. allowing access to the building only to a limited circle of people - these are various types of combination locks installed on the front door of the building: mechanical, electromechanical. electromagnetic or electronic /1.2.3.4/.

The disadvantage of all types of combination locks is their lack of the ability to send a call signal to a visitor in the apartment he needs. if it is a gummy building or in the right room, if it is a production building. as well as in the absence of two-way speakerphone and remote opening of the door lock of the building of the io apartment.

The closest in technical essence is the intercom - lock device containing a side of the code of the desired apartment. key. block for determining the key code, RESET and CALL buttons and subscriber intercoms. for two-way loud-speaking communication with the visitor and with the remote lock release button / 5 / - prototype.

The disadvantage of the prototype is. in some

repair etc. , or when a tenant from this entrance has forgotten or lost the key, it is practically impossible to open the entrance door without damaging the intercom system.

This drawback can be eliminated by introducing the dispatcher’s access block into the intercom and lock device, which provides the connection of a seven-wire communication line of this entrance to the dispatch room, two microphone amplifiers for two-way speakerphone and a side alarm signaling about the open state of the building’s front door.

Figure 1 shows the structural diagram of the intercom locking device.

It contains the code block for the desired apartment 1, key 2. block for determining the key code 3. auxiliary buttons RESET and CALL 5. subscriber intercoms 6 for two-way speakerphone with the visitor and with the remote opening button for zemkz, bpk obrereniya - dispatcher 7, the first and second microphone amplifiers 3 and 9 and the signaling unit about the open state of the front door 10.

The device operates in a sped manner. Pressing the i and 5 buttons consecutively RESET and CALL. located on the front panel of the intercom - lock

devices are triggered by a short circuit relay K4 and K4 at the output b while obrzgtseniya to the dispatcher 7. which contacts K3,1. and K4.1 supply + 24V from the control room to the relay windings K1 and K2, which in turn connect both microphone amplifiers B and 9 to the control room (K2.1. and K2.2.). and contacts K1.1. the microphone of the intercom and lock device is connected to the input of the first MICROPHONE amplifier 3. and contacts K1.2. the speaker is connected to the output of the second microphone amplifier

 about

On the display of the у-dispatcher, the signal lamp of the corresponding i-entrance number lights up. When the dispatcher presses the three-position switch to the left, the position, when contacts a and c are closed, + 24V are sent to bus 1, after which the CALL button 5 can be released, contacts K4.1 . open, but K3.1 contacts. remain closed, and relays K1 and K2 remain on for the duration of negotiations between the dispatcher and the visitor to the entrance. If during these negotiations the dispatcher considers it possible to allow the visitor to open the entrance door of the entrance, he informs him that he can open the door after 5-10 seconds by pressing the 5 CALL button, and he himself switches the three-position switch of the remote control to the right position when the contacts are closed in and s, and the contacts m and n open. When the visitor presses the 5 CALL button, the K4 relay is activated in the access block to the dispatcher 7, contacts K4.1. are closed, point d is connected to the common bus and then relay K5 and contacts K5.1 are activated. provides opening of an entrance door of an entrance. After that, the dispatcher switches the three-position switch to the neutral position (standby mode) when contacts a and c, as well as contacts b and c are open, and contacts m and n are closed and a voltage of 24 V is applied to bus 7.

The alarm block about the open state of the entrance door of the entrance 10 receives information from two sensors - the current sensor of the electromagnet of the lock and the dick of the open state of the door, and if after 20 seconds after the next door opening one of the sensor contacts is open, pulses with a frequency of the order of 1 Hz are generated in the unit served on the relay KB, contacts KB.1 which periodically closes, giving when

-3 signal light,

The signal light will begin to flash at the same frequency as for the dispatcher serves as a signal that the front door of this entrance is open.

The application of the proposed device did not lead to any changes in the console of the integrated dispatch system.

Using the proposed device makes it possible to limit access to residential buildings by unauthorized persons, helps to maintain cleanliness and order in the building, to ensure the safety of engineering equipment and building construction in the house.
