SU22532A1 - Electrical device for signaling the operation of a fire extinguisher - Google Patents

Description

Fire extinguishing devices are already known which, when supplying water, scooped electrical signal circuits. The signal y JTjpOHCTBa are equally well known by the use of an additional battery included in a two-wire cable, which is one m3 of the wires of the main signal circuit and services for monitoring the readiness of the latter to act. The proposed invention relates to a circular electrical signaling device; It is necessary to connect the lamps in the way of switching on the lamps signaling the nickness of the wires of the cable.

The drawing shows the circuit of the proposed devices.

In the two-wire loop g, y through the resistances .RI, KZ, the relay 1 is turned on and. 2, and parallel to the Dz and L. im-lamps. The hearts of these rede are equipped with contact points assigned to close the Mif 2 and Oj, Qz, 0 contacts for the purpose of signal lamps .i and Yes and the call Y. The current source is batteries B and with one pole of the latter grounded. ChIPrinklern; The system is equipped with a “H” catch with contacts closing the float in the “Top” position; . . ..:. .

signal chain. When the water lifts the float H and the circuit closes, the relay 2 triggers, turning on the lamp La sig nlizuyuschuyu that the fire extinguisher is working ..-.

Lamps L1, L and L are used to control the operation of the device. If, for example, one of the wires of the loop is disconnected, relay 1 is turned off, the core expr is released and, under the action of springs or the like, the device closes MI, M, MS, and the lamp i lights up and the bell rings. If a short circuit occurs. the wires of the cable are broken and the wires are grounded, the lamp J3 lights up. Finally, if broken and grounded. the wire . “Then the lamp Jli lights up. Thus, in the event of an accident, the line will be given a corresponding signal, notifying that the signal circuit is not in order ..

The subject matter of the invention.

An electrical device for signaling the operation of a fire extinguisher with the use of an additional battery included in a two-wire circuit with connections that represents eo66ft one of the main signal wires, characterized in that Parallel ABHO relay 1, which controls Line, and parallel to relay 2, The employee who received the signal for the operation of the fire extinguisher, turned on the lamps corresponding to Z 4 with a: th purpose so that during a short circuit the wire of the loop would be lit and the parallel connected. Relay: when the loop is broken and the grounding of one of its wires, the same vJj lamp is lit, when the other wire is broken and grounded, the pagral relay 2 turned on, and when both wires of the loop are grounded, the lamp lights (Fig. 1) .
