Description

The present invention relates to a mycio-ray device for fire and alarm signaling with the control of the voltage of an electrical current source supplying a device in which it is possible both to receive signals from several beams simultaneously and to receive signals from one of them irrespective of the state of the others. each beam of which is consistent with a push-button detector and resistance is switched on by a relay, one of which is triggered when the beam is open, the other is when it is short-circuited.

According to the invention, in the proposed multi-beam fire and alarm device, in order to mark damages with a double signal indicating both the nature of the damage and the beam in which this damage has occurred, the applied optical indicators are turned on through the contacts of the corresponding linear breaker relays and the message included into the beam chain in such a way that simultaneously with the igniting lamp indicating the nature of the damage and the damaged beam, using local

break and message relays turn on common optical and acoustic indicators, and when an alarm is received, the beam that feeds this signal is produced by two-teeth valves, whose circuit is closed using a linear break relay, including alarm relays, which short-circuits the common optical and acoustic indicators anxiety

The multipath device for fire and alarm signaling, the electrical circuit of which is shown in the drawing, in OCHOIBHOM consists of: 1) a KI pushbutton detector installed at the signal point of each beam, the circuit of which is powered by an LB battery is connected in series with a short-circuit relay and LRO breakage relay with switch D, L / S short circuit lamps and LO breaks and a plug socket G for connecting an inductor beam to the line / to give a response signal; 2) of the common for the whole Device is the grounding relay LRZ, alarm relay RT, relay RO, relay short circuit Р / С, bell relay РЗ, relay RCB control of the local battery MB, the supply circuit of all common

l device devices, dual-tooth alarm KT, calls: alarm ST, control battery 3KB, damage j / 7 and warning lights: alarm LT, control battery LKB, j short circuit OLK, breakage OLO. When the beam is operable, the LRK short-circuit relay and the LRO open circuit relay are included in the linear battery LB circuit and a current flows from the plus winding of the LB battery through the windings g, springs 2, 1 of the plug socket G, wire a, resistance R, wire b, springs 4 and 3 sockets G, the winding of the linear relay LRO, springs //, / About switch / Zj, the winding of the LRK short circuit linear relay to the minus of the same battery. In this case, the LRW relay bore will be pulled in and close one of the ends of the CT valve winding to the idle contact connected to the spring 7 of the ZTb switch, therefore its winding will be without current and the valve door will be kept from falling by the lower tooth. The LRK short-circuit relay does not work at the same time, although the current passes through its winding, since & BUT is adjusted to current levels exceeding the normal ones. The alarm is sent by pressing the K button on the detector KI. Here, the signal circuit is first opened for a very short time and immediately thereafter closed again. During the short opening of this circuit, the LRO relay will release its measles, which will close the coil of the LP valve to the MJS battery, i.e. the current will flow from the plus of the local MB battery through the springs 6, 5 of the G socket, the springs, 9 switches I), the bottom contact of the LRO relay, the CT winding to the minus of the same battery. The valve anchor is attached, the prong will release the door, which will fall, but will not fall, but be delayed by the second upper tooth. When the button is released after the signal is pressed, the signal chain is re-closed. The QD valve bore is released and under the action of the spring rises, releasing the door, which falls and closes the winding of the alarm relay RT, which activates, turns on the common RT alarm light and the bell 57 or the loud bo shown on the drawing) or any other acoustic signaling device. Upon receipt of an alarm should give a response signal. This is done by inserting the plug W into the socket G and rotating the knob of the inductor I. In this case, the response signal goes in parallel along both branches of the loop that connects to the detector button and passes through the call 3 to the ground. The relay PO, on the winding of which current will flow when the button is pressed, has a long delay time and therefore it does not work.

If one or both wires of the loop of the LRW winding breaks, the measles are released and the circuit is closed: plus MB, springs 5, 6 sockets G, springs 8, 9 of the HI switch, lower contact of the LRO relay, broken LO lights, PO breaker, minus MB . The LO lamp lights up, the RO relay triggers and turns on the OJJQ common break lamp and the RFK damage call.

When grounding one cable of the loop, except for the circuit of the circuit during an open circuit, the circuit closes: plus LB, springs 2 and 7 of socket G, loop lines, earth leakage, earth of the LRZ linear grounding relay, winding last, milliammeter MA, minus LB. In this case, an LRZ relay is triggered, closing the relay relay circuit with an LZ lamp from plus MB, an LRZ top contact, springs / 5, J4 of the Po switch, an earthing switch of the RZ relay, a winding of the RZ earthing relay, which turns on the damage alarm bell. Relay. LRZ can work without full grounding in the loop. To energize a relay, it is sufficient that the leakage current to earth exceeds a certain amount by which the relay is regulated. To monitor the correct operation of the relay is a milliammeter tL.h

In case of a short circuit of a beam, the current in the signal circuit will increase so much that the linear short-circuit relay LRK will work, which will turn on the LAM box of the LC in the battery circuit of the battery, and the coil of the relay RK. The plug is a HI switch. The LRO relay switches current and releases its measles, and closes the circuit of the valve winding AT, the door of which will be released by the first tooth and retained by the second upper one. In this case, it turns out. possible alarms despite the presence of an unresolved connection between the lines. When the push button is pressed, the detector closes the circuit: plus LB, springs 12, P switch ZTi, winding relay LRO, springs J, 4 sockets G, line b, left contact and ground buttons, ground of the ground relay LRZ, winding last, minus LB. Relay LRO pr no, valve / SG will be deprived of current. When the signal circuit is opened (after the button is released), the CT valve will again reject the measles, than the latter will release the door, which will also close the PT relay.

The health of the local battery is controlled automatically by the RKB battery control relay, which is normally energized. In the absence of a sufficient voltage on the battery terminals, the RKB releases its measles, including the LKB battery control lamp and the VCB battery control bell, powered by an LB linear battery. When a linear battery malfunctions, all light bulbs are broken, the common light is broken, and the damage bell rings. Signal bulbs are preferably made in different colors (for example, white; red, green) and supplied with appropriate labels (open, alarm, earth, etc.). Instead of calls, any other acoustic signaling devices can be used.

The subject matter of the invention.
