Description

The utility model relates to the field of safety, in particular, to technical means that ensure the evacuation of people from buildings in case of fires, disasters and power outages, namely, emergency lighting devices.

A comprehensive warning system for emergencies, illumination of escape routes and fire-fighting equipment, as well as the organization and distribution of people’s flows during evacuation (PM No. 663092 RU) is known, containing a power supply and light warning units included in the fire alarm system, additionally mounted on the ceiling , light sirens emitting light spots along the entire route of evacuation of people and locations of fire extinguishing means, communications, alarms, etc., while using light sources as s LEDs. Light annunciators are made in the form of narrow plastic boxes, for example, three meters long, mounted on the ceiling or wall. Some light sirens may have a second-level power supply. The emergency lighting system is activated by a command from the control panel, including the lighting of warning lights according to a specific program, forming flashing “light tracks”.

The disadvantages of the proposed emergency lighting system are: the need to install a large number of light boxes in the building, which spoils the interiors and is not always possible, as well as the cost of construction and installation works due to additional labor costs. The flashing mode of the lamps in an alarming situation causes psychological stress of evacuated people and contributes to panic. Emergency lighting from the fire alarm control panel does not start, for example, with a simple power outage in the building and requires manual control. Management of “running” light paths requires a large number of wires, which makes the system more expensive and complicated.

To address these shortcomings, an emergency LED lighting system is proposed based on the elements of a security and fire alarm system (OPS) and video surveillance installed at the facility.

To this end, it is proposed to use detectors, junction boxes and video camera boxes and other equipment with integrated LED emergency lighting (VSSAO) in fire alarm and video surveillance systems. The output circuits of the VSSAO are connected to uninterruptible power supply units distributed over the floors of buildings that have a circuit for supplying voltage to the lamps during a power outage in the building.

The essence of the utility model is that light sirens based on superbright LEDs of white, yellow or red light are installed in the holes on the covers, bases, mounting rings, firefighters, security detectors, loudspeakers, junction boxes and video camera boxes, and are mounted in them wires or on additional or main boards equipped with additional screw clamps, terminals or wires and not galvanically connected to the electronics of detectors and video cameras, at the same time, feel The detector elements connected to the emission of emergency LEDs are protected by screens formed by boards and optically opaque elements on boards on which the LEDs are soldered, and / or by screens on LEDs, moreover, light sirens are connected in parallel to a common low-voltage direct current network, the voltage of which from uninterruptible power supply battery appears when the power failure of its voltage converter voltage of 220 V AC, switching by means of a relay or an electronic key.

The emergency LED lighting system is mounted simultaneously with the installation of the fire alarm system, acoustic warning and video system of the building (Fig. 1.). In this case, equipment is used that has built-in LED lights with white, yellow or red super-bright LEDs. The system consists of an uninterrupted power supply (BIP) (1) with a voltage converter (2) that charges and monitors the battery (3); a relay or an electronic key (4) that connects the battery (3) to the power supply circuit (5) of the VSSAO, made of a copper wire with a cross section of at least 0.5 mm, to which fixtures in the housings are connected in parallel: smoke detector (6), infrared - wall (7) or ceiling (8), acoustic (9), door (10) security detectors, manual fire detector (11), box (12) video cameras, loudspeakers (13), junction boxes (14), thermal fire detector ( 15) or other elements of the OPS.

The power supply from the emergency lighting BIP (1) is connected to the corresponding additional terminals or wire outputs of the detectors and is galvanically isolated from their main circuits.

A smoke fire detector (6) (FIGS. 2, 3, 4) with a built-in LED lamp has openings (17) for superbright LEDs (18) in the upper part of the cover (16). The LEDs (18) can also be located on the base (19) of the detector or on a separate mounting ring (20), used to install smoke detectors in suspended ceilings, in the holes (21). All LEDs on the detector are connected in parallel through current-limiting resistors (22), and are output to additional terminals (23) based on the detector (24) and to terminals (25) on the base (19) (Fig. 3.). Under the cover (16), the LEDs are soldered on a circuit board (26) located above the smoke chamber (27) and preventing light from the LEDs (18) from entering the smoke chamber. The circuit board (26) has a central hole (28) to test the detector's operability, in which there is an opaque tube (29), which also prevents light from the LEDs from entering the smoke chamber and at the same time directs the test rod into the smoke chamber opening. Current limiting resistors (22) and conductors (or connectors) (30) connecting LEDs with additional terminals (23) are also located on the board (26). When the LEDs are located on the base (19), the LEDs (18) are soldered onto the ring board (31) (or simply conductors) inserted into the ring recess (32) of the base (19). The terminals (25) of the base (19) (Fig. 5), to which the wires from the BIP are connected, are screwed directly to the contact pads (33) of the board (31). When the LEDs are located both on the detector and on the base, emergency lighting will be functional even if the detector (6) is removed from the base (19).

On the mounting ring (20) (6, 7) for installing a smoke detector in a suspended ceiling, LEDs (18) are installed in the holes (21) radially located on the lower surface of the ring and are soldered to each other and current-limiting resistors (22) on the ring board similar to (31), or conductors (34). The circuit board or conductors are closed by an annular cover (35). The power supply to the VSSAO of the mounting ring from the BIP is carried out through the wires (36) (+ - AO).

In a thermal fire detector (15) (Figs. 8, 9), LEDs are placed on a ring board (37) under a perforated cover (38) fixed to the base (39). The board has a central hole (40) for the detector thermocouple. The LEDs (18) on the board are arranged so that light from them freely passes through the holes in the perforated cover (38). The power supply to the VSSAO of the heat detector is carried out by wires (41) (+ - AO) or through additional terminals on the basis of the detector or on the board (37).

In manual fire detectors (11), super-bright LEDs (18) are placed in the holes on the front cover (42) (Figs. 10, 11), soldered to the detector board (43) with the addition of additional screw terminals (44).

In the security (IR, ultrasonic, etc.) detector (7), the LEDs (18) are located on the front cover (45) (Fig. 12). They are either unsoldered on a separate board (46) (Fig. 13), fixed on the inner surface of the front cover of the detector and connected to the network (5) of fixtures with wires (47), or installed on the main board (48) of the detector mounted on the back lid (49) (Fig. 14.), with the addition of additional screw clamps (50) (+ - AO).

In the ceiling infrared security detectors (8), the LEDs are arranged radially on the cover (51), soldered to the detector board (52) with the addition of additional screw clamps (53) (+ - AO) (Fig. 15, 16.).

In acoustic detectors (9) (Fig. 17), the LEDs are soldered on the detector board, similarly (Figs. 14, 15, 16).

In the door security detectors (10) (Fig. 18, 19), the LEDs (18) are inserted into the holes of the top cover (54) and soldered between themselves and current-limiting resistors (22). The reed switch (55) of the detector is located in free space under the LEDs. From the detector housing, the wires (56) of the luminaire (+ - AO) are output as a separate pair in a four-wire cable.

In the boxes (12) of the internal dome cameras, the emergency LEDs (18) are installed in the holes along the perimeter of the box lid (57) (Figs. 20, 21). The LEDs are unsoldered on the board (58) with the terminals for additional screw terminals (59) (+ - AO).

In the loudspeakers (13) of the ceiling (Fig. 22) or wall (Fig. 23) type, the LEDs (18) are located in the holes of the speaker ring housing or the front cover and are soldered on separate boards or wires, with the output to separate terminals or wires (+ - AO).

In the junction boxes (14) (Figs. 24, 25, 26), the LEDs are installed in the holes of the top cover (60) and soldered on a separate board (61) with the terminals (62) (+ - AO).

The emergency LED lighting system based on security and fire alarm and video surveillance elements works as follows:

When installing fire and burglar alarms, loudspeakers, junction boxes and boxes of dome cameras in buildings, equipment with built-in super-bright LEDs is used or extra-bright LEDs are built in to the detectors, limiting resistors and additional terminals independently.

When installing detectors use cables with an additional pair of wires for emergency lighting (+ - AO). Uninterruptible power supplies (1) with voltage converters (2), batteries (3) and relays or electronic switches (4) are installed on the floors of the building. Along the corridors, a main circuit (5) is used to supply emergency lighting with a copper wire with a cross section of at least 0.5 mm ² . The VSSAO wires (+ - AO) from the smoke (6) (via terminals 25), thermal (wires (41), infrared (7) (through terminals 50 or wires 47), and acoustic cables of the same type (8) are connected to it. infrared ceiling (via terminals 53), door (9) (wires 56), mounting rings of smoke detectors (wires 36), box (12) cameras (via terminals 59), manual fire detectors (11) (via terminals 44), switching boxes (14) (wires 62) and loudspeakers (13) in parallel, based on up to 40 fixtures per one BIP.

They turn on the voltage converter (2) in a 220 V network. In this case, a relay or an electronic switch (4) disconnects the power circuit (5) from the battery (3) and it is de-energized. If the mains voltage fails, a relay or an electronic key (4) connects the open circuit of the power supply (5) with the battery (3), and the lamps light up. Since rooms usually have at least two smoke or heat and one infrared, acoustic and door detectors, and sometimes a video camera, loudspeaker and a junction box, at least 4-5 LED lamps begin to shine in the room, which provides sufficient illumination for evacuation. In the corridors, in addition to fixtures in smoke detectors, fixtures are added in manual fire detectors, video camera boxes, IR and acoustic detectors, loudspeakers, which also provides the necessary lighting for evacuating people.

Charging one 7.2 Ah battery is enough for 5 hours of illumination of 40 LED lamps with a luminous intensity of each LED in the lamp from 8000 to 12000 mCd.

When using LED lamps built into the annunciators of the OPS and video camera boxes, equipment is saved - separate emergency lighting fixtures are not required, time and money are not wasted for installing separate luminaires from the OPS equipment, emergency lighting system maintenance is simplified, and reliability is improved due to decentralized power supply and control , the functionality of the elements of the OPS is expanded and the number of lighting points in each room increases. It also facilitates the installation of alarm equipment in dark, de-energized rooms, as anywhere in the workplace lighting can be provided by connecting the nearest detector to the BCCAO battery.
