The second is Yiguang, Longitudinal and horizontal, Ping an, Qihui, Zhenhui, the performance price is relatively high, the brightness of emergency is higher than Minhua, Lloyd’s, and Pinast lights, but the emergency time is slightly shorter, and the price is slightly lower.
The performance and price of Yiguang fire emergency lighting is relatively high, and its brightness is better than Minhua in emergency. Minhua Fire Emergency Lighting is the most widely used brand with a long life.
Which brand is good for fire emergency lights?? Minhua is an enterprise with high competitiveness in the domestic market, the executive director of Guangdong Illuminator Association, a famous brand, Jiangmen Minhua Electric Appliance Co., Ltd.
Why does the emergency light turn on automatically when there is a power outage?
1. There is a storage pool inside the emergency lamp, which flushes power when there is no power outage, and the circuit will be automatically switched when there is a power outage, and there is battery power supply, thus playing the effect of lighting.
2. The emergency lamp can be illuminated when the normal lighting power supply fails, and it can effectively illuminate and display the evacuation passage. Principle: emergency lighting is composed of light source, light source driver, rectifier, inverter, battery pack, sign lamp shell and so on.
3. There is a relay in the emergency lamp. The coil of the relay is powered by AC, and it always keeps the suction state when there is AC power. When there is a power outage, the relay is released, the battery and the light bulb are closed and turned on, and the light bulb glows. There is a charging control circuit in the emergency light, which can charge the battery intelligently and stop charging automatically when the battery is full.
4, emergency lights will also be annual self-test, every 365 days on, about 30min-1h, or clean battery electricity, is also a normal phenomenon. If the monthly self-test is less than 30s or the annual self-test is less than 30min, the lamp will automatically alarm (the fault light flashes, the buzzer ticks) to remind you to replace the battery, and then the battery needs to be replaced.
5. What is the reason why △ fire emergency lights are always on? under normal circumstances, the fire emergency lights are automatically monitored and not lit at ordinary times, only to monitor whether the power supply system is normal or not, and to keep enough electricity in the battery. Only after the power is cut off, the battery in the emergency lamp lights up the light.
6. According to our analysis, first of all, it is a lamp. If you give him electricity, he will turn on, and if he does not turn on electricity, he will not turn on.
How to connect the emergency lights
Controllable: features: the emergency lamps can be turned on or off at ordinary times, and the emergency lights can be lit immediately after a power outage. K is the control switch, and this connection is the most common connection of emergency lights. Note: yellow and green wires are grounded.
How to connect the emergency lighting tube, first remove the screws of the emergency lamp through the props, and remove the shell. Set the three wires in the emergency light to the control panel, and then plug the cable into the panel. Connect the power supply of the emergency light to the external power supply, and then connect the fuse.
Fire emergency sign lights in the case of no power plug (three-wire connection mode), generally red (dark red) power cord is hot wire; blue power cord is zero wire: yellow and green power cord is ground wire. It can be used for reference when installing the wiring of fire emergency sign lights.
Wiring method of fire emergency lamp
1. The fire emergency sign lamp has no power plugIn the case of (three-wire connection)The power cord that is usually red (dark red) is the hot cordThe blue power cord is zero: the yellow and green power cord is the ground wire. It can be used for reference when installing the wiring of fire emergency sign lights.
2. Controllable: features: it can control the emergency lamps and lanterns on or off at ordinary times.The emergency lights were lit immediately after the power outage. K is the control switch, and this connection is the most common connection of emergency lights. Note: yellow and green wires are grounded.
3. The characteristics of various wiring modes should be accurately grasped so as to avoid blind wiring and can not play its due role. If emergency lighting is used as a part of usual lighting, three-wire controllable connection method should be adopted.
4. The strong start line of fire emergency lighting is not much different from the ordinary emergency lighting line, which is usually a four-wire system, including normal lighting line and charging wire, strong start line, zero wire (N), protective grounding wire (PE).
5. Single-lamp single-control or multi-lamp control) or three-wire connection with centralized control in the distribution box. For the project with the fire control center, in order to meet the requirements that the fire control center can open the fire layer and the related layer fire emergency lighting when the fire occurs, the wiring mode of figure (5) and (6) should be adopted.
What is the principle of the emergency evacuation lighting indicator, and why is it still on after a power outage?
1. There are many kinds of emergency evacuation lights, which usually store electricity in peacetime, and then turn on when the power is cut off.
2. The reason why the fire emergency light is always on has been mentioned above: it may be that the capacitance of the emergency lamp is broken down; when the voltage of the city electricity is extremely unstable, the electronic components of the lamp are subjected to a strong high-voltage electric shock, which leads to the instantaneous temperature of the electronic components being too high and the breakdown short circuit.
3. There is a storage pool inside the emergency lamp, which flushes power when there is no power outage, and the circuit will be automatically switched when there is a power outage, and there is battery power supply, so as to play the effect of lighting.
