Is there a four wire controllable strong start evacuation indicator?

Emergency lighting and evacuation instructions can be wired in a variety of ways.

Normally: emergency lights wear three wires, safety exit lights wear two wires, and evacuation lights wear three wires.

Three-wire with fire control module: one for each ground and one for the fire;

What is controllable with strong start (four lines), controllable without strong start (three lines), normally closed with strong start (four lines), normally closed without strong start (three lines) and so on. I can't count them, but I can only name some common ones.

Evacuation instructions are:

Three-lined: one for each of the fire and the ground;

Four-wire (lamps with batteries): floating charging wire (fire), power line (fire), neutral wire, grounding wire.

Anyway, there is only one neutral and ground wire.

Extended Information: The Difference Between Emergency Lights and Safety Exit Lights:

Exit light installationsA light-emitting plaque indicating pedestrians to travel safely in rooms with two or more doors, staircases or corridors is often installed above the exit door. In the event of an emergency, people can get out of danger safely and quickly by walking in the direction indicated by the exit light. The emergency lighting does not light up when there is sufficient natural light, and when the power failure causes the lights in the room, staircase or corridor to be unlit and the light is insufficient, it will automatically light up to provide short-term emergency lighting for people to walk and evacuate from dangerous areas.

No, I'm sorry.

Two power lines and two communication cables.

Isn't that troublesome? The wrong line is often connected during construction, resulting in equipment damage and extremely low efficiency.

Intelligent evacuation is now basically using the two-wire system, using the powerbus two-bus chip, upgrading the product to a two-bus intelligent product, and the four-wire becomes two-wire. The construction efficiency is improved, and the cost is saved

You refer to 4 wires, it should be 3 phase 4 wires, connect the indicator light, use the indicator light to connect a terminal to the switch outlet line n position, the original rear indicator light another wire head is connected to the switch outlet line l position, I refer to the indicator light is 220 volts. If it is a 380 volt indicator light, connect the two terminals of the indicator light to the L1, and L3 positions of the switch outlet.

The landlord is talking about the evacuation indicator with a strong start function, but it is not a 380V lamp

Emergency Lighting Copy:

Usually it is 3 or 4 roots, depending on the drawing requirements.

When there are 3, it is the live wire, the neutral line and the ground wire;

4 have an emergency light line, which is done according to the form and requirements of the emergency lighting box.

Evacuation Indicators:

Three-lined: one for each of the fire and the ground;

Four-wire (lamps with batteries): floating charging wire (fire), power line (fire), neutral wire, grounding wire.

Hello, 3 lights need 4 wires for the same pipeline, the zero line is a public line, and the 3 live wires are connected to the emergency lights, safety exit indicators, and evacuation indicators.

Now look at it, all manufacturers are doing two-bus schemes, and two-bus is only using two lines. Usually it is still non-polar wiring, and you don't need to estimate how to connect it, just match it casually. Brands like Chongzheng, Jade Bird, and Taiyi are all two-bus systems.

You can go and see how the two-bus system has become mainstream.

Evacuation instructions are generally available on three lines, the source or four lines, depending on your lights. The emergency lighting circuit depends on whether you are centrally controlled or on-site, that is, whether there is a switch? Or is it directly controlled by the circuit breaker in the distribution box?

Add another wire to the switch control. If the distribution box is controlled, I feel that the charging cable is useless.

Lamp power supply line copy wdzn-byj (f) lamp communication line.

Baidu controls the communication line between the device and the power supply.

Power supply line of the main DAO station and distribution device: wdzn-byj(f)-3x4

All of them are three wires, the neutral wire, the live wire, and the ground wire.

The indicators and emergency lights of the all-outlet BAI belong to the centralized control type ZHI emergency evacuation system, and their control and internal power supply are controlled by two Powerbus buses that distribute the output of the capacitor device. So they share a set of wires and belong to the fire protection weak current system.

The static power consumption of the indicator light is generally around, and the size of the emergency lighting varies from 3 to 10W, which requires a strong power supply capacity, and only the PB331 power supply chip in China can meet the requirements.

From the safety point of view, there must be a grounding wire (connected to the fire emergency fluorescent lamp shell) in accordance with the requirements of the specification.

In general, the two white wires of the emergency power supply are connected to the energy-saving lamp, the red line is connected to the Changming line, the black wire is connected to the switch live wire, and the blue wire is connected to the zero line. (There are also some products with different wire colors, depending on the wiring identification on the emergency power supply). The installation is the same as that of a normal downlight, except that an extra emergency power supply is added to the ceiling.

Emergency lights are installed in the same way as ordinary ceiling lights. Wiring: The switch wire is connected to the lamp head, and the Changming wire is connected to the emergency power cord. Neutral line sharing.

There are a total of 4 wires: one directly connected to the fire wire (fire status and daily charging cable), one connected to the switch wire through the switch (normal lighting), one connected to zero, and one connected to the ground.

1. Battery charging circuit.

The external power supply is charged by Q2, Q6, R8, D10 for constant current charging. When there is an external power supply, the charging current is charged to the battery through R8, D10, and the charging indicator D12 is lit.

2. Lamp control circuit.

It is composed of Q3, Q5, Q7 and the key K, G, when there is no mains, press the K (on) button, Q5 saturation conduction, and the collector current of Q5 passes through R12 to keep Q7 conductive; D11 reverse breakdown works in a regulated state, and the collector voltage of Q5 provides a bias to Q3 and Q4 to make it on, lighting up L1 and L2.

When the G (off) button is pressed once, Q7 is cut-off, the Q5 conduction condition is removed, and the light is turned off.

3. Test circuit.

When the test button S is pressed, the QL is cut off, and the negative potential of D7 becomes low and the positive deviation is turned on, so that the Q5 conduction meets the lighting conditions, and L1 and L2 are lit. Release the S key and the light will go out. The function of the test circuit is to test whether the lighting circuit is normal.

The four-wire system is the live wire, the neutral wire, the ground wire, and the strong start line, and the access can be done.

The so-called fire emergency light is in the state of firefighting, there is a control center to directly control the fire control box, forced start, normal three lines to meet the control function, fire, and then another line directly skips the on-site control switch to turn on the emergency light to light up, and force start.

No, the emergency lighting, evacuation: dispersion indication have their own charging system inside, no need to add a charger.

The grooming indicator has its own charger inside.

No, it is fully equipped. It's ready to use right from startup.

No, it comes with a charging port.

Three-wire with fire control module: one for each ground and one for the fire;

Strong activation can be achieved by external wiring.

External wiring: a normal live wire (which can be used to control the usual light or charging), an emergency strong fire wire (in the same phase as the normal live wire, provided by the contactor of the strong start), a neutral wire, and a grounding wire.

The internal wiring depends on the manufacturer's relevant product manual.

Is there a three-wire kind, two are connected to 220V, and one is connected to the switch, and the other end of the switch is connected to the red line.

If there is no battery, two wires into 220V are enough.

Two wires, one positive and one negative.

4 wires - live wire, neutral line, PE line, strong start line.
