Description

The proposed fire alarm device is of the type of such devices in which the signaling device is a bipolar switch, made in the form of a push button.

In FIG. 1 shows a circuit diagram for connecting linear circuit devices; FIG. 2 is a diagram of the connection of devices of the local circuit; FIG. 3 is a control plug circuit with a volt-ammeter, FIG. 4-coro coaxial and FIG. 5 is a diagram of the connection of the microtelephone with the plug.

The device consists of, installed in protected places, signaling devices, made in the form of bipolar switches, opening and closing, when a signal is applied, a linear circuit and has a device for signaling when the line is damaged. The device allows the use of a series of parallel circuits, and the action of each of the circuits is carried out using instruments of a linear circuit consisting of: signaling devices 1 and 2, in the form of push buttons, a reverse signal bell, a linear conductor SB, a high-current Pa fuse, a plug sockets 151, linear blender relay A with kor / and pointer t, plug socket 52, battery LB with derived midpoint 51, resistance coils C, sockets 152, high current fuse PB, linear wire b, additional relaxed a ker 5 with a plug, a plug socket 52, a switch 81 with contacts 11, 12 and 13, a plug socket 53, a plug 94 and socket 54; and a local circuit consisting of: a local battery MB, a socket 55, a box / and an indicator of a relay A with a contact 11, 12 and 13, a relay an alarm mixer 11, a switch 82 with a contact 11, 12, 13, a box / Blender Relay B with pins 11, 13, 21 and 24, Fault Ring 116, Switch 81, Relay Indicators - Alarm Blender and Alarm Ring.

In the normal position of the device, all the linear circuits are closed, the core of the linear relays of the blenders included in the linear circuit is pulled and their dropdown indicators are in the raised position, while the local circuits are open. The current path in the linear circuit will be: -f- linear battery LB, plug socket - 51, resistance coil - C, plug socket-152,

strong current protection PB, line wire b, return signal bell-1116, fuse / 7s, line wire a, plug-in socket-151, line relaxer-A, socket-52, -LB. The negative pole of a linear battery is connected to earth in the following way: -LD socket-52, contacts 12-11 of the switch 81, socket-53, contact 11 of the socket-61, plug-94, contact 12, socket-54 and ground.

When button 1 is pressed to give a signal, a current interruption is obtained in the linear circuit, and the measles / relay blender-A disappears, and its pointer t drops out, closing contacts 21-22. When the button is pressed down, the linear circuit closes, the measles / relay-blender A is attracted, and the following current path in the local circuit closes: -) - I / D socket-55, contacts 11-13 and 21-22 of the relay-blender A, blender relay alarm-llS contacts 12-And the switch - 82, socket-56, -MB. The pointer t of the Blender Relay P drops out, the closure by contacts 21-23 of the alarm bell-136 circuit.

To receive the station signal

0 from the button number 1 indicate:

1) dropped pointer t of linear relay-blenker-A;

2) the dropped pointer t alarm-11 alarm;

3) the alarm bell-136 that started ringing.

If the device is made with a device for giving a reverse signal on direct current, after receiving the signal from button No. 1, the plug-95 should be inserted into the sockets 151-152 for some time, thereby closing the following current path: - | -. 51, upper plug plug 95, socket-152, line, bell-1116 button 1, return wire, where the socket is 151, lower plug plug-95, 52, -LB. The current in the linear chain

1 so it’s been raised that the 1116 feedback call starts working.

When a line is damaged in a linear circuit in a blender-A relay, the current stops, as a result, its pointer m drops out and the malfunction call is turned on - 116. To determine the nature of the damage, you should turn on the voltmeter 31 by inserting the plug-96 into sockets 151-152, with If the ground plug is grounded, neither inserting the 97 plug into the sockets 151-152, nor removing the plug -94 from the socket 61 will make it possible to raise the dropped indicator of blenker A. To turn off the call 116, switch switches 82 and 81, insert the resistance plug C -91 in slot 152, raise Blender A relay and put switch-82 in normal position. When translating the switch -81 with its contacts 11-12, the connection to the ground of the negative pole LB is disconnected, instead of which the middle point LB is connected to the ground by contacts; With pins 21-22, the malfunction-116 ring circuit is opened.

When the plug -91 is inserted into the socket-152, parallel to the resistance coil -C, an auxiliary blender, B, is turned on, the pointer falling out of which and the closure of the contacts 21-24 occurs only after closing and following it the current flowing through the considered blender.

Since, when the button is pressed, the latter produces successively opening, closing with simultaneous grounding, opening and normal linear circuit, the reception of the signal, after the indicated switchings, is assumed to be provided when the ground is open.

In this case, in case of wire breakage a, coming from -BB, at the moment of pressing the button, the following path is closed: - -LB, C, 152, linear wire b, ground in the cable, ground in the device, 54, pin 12 of the socket 61 , plug-94, contact-11 sockets-61, socket-53, contacts

11-13 switch -81, middle point LB, and in case of breakage of the wire / going o1 - {- LB, the following: middle LB, contacts 13-11 switch 81 socket-53, socket-61 with a plug-94, socket

54, earth in the apparatus, earth in the message button, linear conduit, a; 151, blenker A, 52, - LB. Switching on, alarm in the second case occurs on the current paths already considered above, and in the case of the first, on the following path: - -,

55, pins 21-24 blenders B, alarm blenders 11, pins 12-11 switch 82, 56, -L /.

In the case of the first, upon receipt of a signal, the pointer m of the auxiliary blender, B, does not appear, which does not give a direct indication of the number of the button pressed. The location of the signal, in this case, is determined by the position of the plug — 91, since it is obvious that the signal came from that button, into the linear socket of which (152, 252, etc.) the plug was inserted. In order to give additional instructions from the signal location, a handset is used, which connects the plug 1040 to the socket in the circuit with the signal button of the patent.

1. DeviceFREE alarms, consisting of signaling devices interlocking in

and closing, when a signal is applied, a linear circuit, characterized in that the signaling devices are made in the form of two-pole switches 1, 2, in one position involving a linear circuit electrical calls for receiving a reverse signal, and in another position of grounding wires a, b , of which wires the wire a is connected to the linear battery through the relay-blender A, and the wire b- through the resistance C, short-circuited when giving a return signal, or shunted by an additional relay-blender C when the wire is broken it, for the purpose of using the linear conductors at their lesions x, applied switch 81, the earthing or a linear battery pole connected to a wire, or its midpoint.
