Description

 The invention relates to alarm devices intended for fire and militarized guards with a large number of posts located on the same ring wire.

In the device, pulsed electromagnetic mechanisms such as searchers are used for optical reproduction of pulsed signals, the contact fields of which mechanisms are connected to signal lamps in such a way that the lamp being searched for will be at the intersection of two contact lines of the searchers.

The essence of the invention lies in the fact that the detector uses a locking electromagnetic device in order to slow down a typical wheel while simultaneously giving more than one signal, which device is included in the battery circuit through the second-row brushes of the searcher and is provided with a bark, which protrusion is intended to enter the cut-out pulse wheel.

In FIG. 1 depicts a diagram of the alarm system in which the proposed device is applied; FIG. 2 schematically the device itself.

When the code wheel in the detector is put into rotation, the linear circuit opens and some number closes

times, which is caused by the operation of the gear wheel. The LR and LR relays (Fig. 1), powered by the battery 5i, release the measles when the circuit is opened. send current pulses to the windings of electromagnets seekers. When the Schleif circuit is first opened, the slow-acting MP relay opens and opens contact 3. The MP relay does not respond to short pulses, and the relay of this relay remains pulled until the loop is permanently closed between the first and second groups of current pulses, i.e. when the spring 9 will be on the long protrusion of the code wheel 8 (Fig. 2). The current pulses from the linear contacts, the JJPi and LRz relays are directed to the electromagnet 9i and the searchers And along circuit 1: plus, contact / contact / contact, contact 4, winding E, minus. The Ifi finder receives the first group of pulses and moves the brushes to the corresponding contacts, for example, to contacts 4. Now, when the loop is closed for a long time, circuit 1 is open for a long time, as a result of which the MR relay releases the measles and closes contact 3, the BPi relay will operate and block your contact 7. Contacts 4 and 8 are closed and contacts 3 and b are closed. Pin 4 turns off solenoid E electromagnet And pin 5 turns on

Elektromakyyit gEz Iskatel I, and the subsequent group of current pulses (group of units) is directed to electromagnet E tie of circuit 2: plus, contact 7, contact 2 L77, contact 5, contact / 5.

At the end of the current relay pulses

- ZHR will release the measles again and will give plus the YaRz relay. The BR relay will work and will be blocked by its contact 16. Contact 14 will close, which will close the current circuit of the signal lamps of the SL. If the brushes “skatel 1” stopped, as indicated above, on pin 4, and the brushes of the searcher 2- “and contact 5, then the circuit is closed: plus,“ contact I p and the searcher HI, lamp, 5 contact 14, contact 77, minus. With the output of the brushes, the ill-in sequence of the HI finder from the initial position is closed. The acoustic signal circuit (buzzer or ring tT) closes. The device is reset to its initial position by pressing the SB button, and the relay Ps, receiving a plus from the KB button, will activate and lock its contact 72.

1, contacts 10, 77 and 75 are closed, and contact 77 is opened, which extinguishes the signal lamp. Contacts 10 “77 turn on the pulse-PR relay in parallel to both searchers, and pin 13 delivers the minus relay BR through the finder // 1 brushes in order for the BR relay to block only when the brushes of both searchers return to their original position. When the brushes of the searchers go to the zero contacts, the Pulse-Relay is turned off and the BR, BR and BR relays unlock because they lose their minus, i

If almost simultaneously, without waiting for the receiver to return to its original position, more than one alarm signal is given, then subsequent signals are received only after the receiver has been reset to its initial position after receiving the previous signal. Said according to the invention is carried out as follows. The alarm detectors are equipped with an electromagnetic locking device (Fig; 2), the electromagnets of which device receive current at the meeting of brushes of a number P of the searcher I from the zero contact, as a result of which the electromagnet 7 (Fig. 2) attracts the curie 7 washers 8 and stops the type wheel. When the receiver / is brought back to its original position, the electromagnet 7 is deprived

current and. releases its measles, freeing the typical wheel, which comes into rotational motion. The disk 5 with a spike 4 and contact springs 3 n 6 serves to turn off the electromagnet 7 at the beginning of a pulse in order to facilitate the rotation of a typical wheel, which would be slowed down by a spacing of the core 7 on the brake disc 8.

The subject matter of the invention.

A device for alarm signaling designed for fire and militarized guards with a large number of posts located on the same ring wire, using pulsed electromagnetic mechanisms of the type of searchers for optical reproduction of the IM pulse signals, the contact fields of which mechanisms are connected to signal lamps in such a way that the lamp being searched will be located at the intersection of the two contact lines of the searchers, characterized by the use in the annunciator of the arresting electromagnetic field sposobleni in order to model the wheel braking while supplying more than one signal, what device is included in the battery circuit through the second row of the brush searcher HI and the armature 7 is provided, whose projection is intended to enter into the cutout brake disc 8 impulse wheel.
