Emergency Lights Emergency Function Can Be Realized Automatically When Power Failure Occurs

1, the first Emergency Lights classification:

A, according to the different control methods are divided into: no control, in-situ control, centralized control;

b, according to the lighting time is divided into: steady (such as the direction of evacuation lights and safe exit signs), fire or power failure Shikai Lian (such as double headlights);

C, according to the strong starting mode is divided into: fire control room signal strong start, charging detection line after the power loss with battery power;

D, according to whether or not to bring the battery: from the battery, not with the battery;

E, according to the number of light source lamps are divided into: the normal light source and emergency light source Emergency Lights, only contain emergency light source emergency lamps.

2, Emergency Lights wiring: First of all, we only have emergency light source and the battery of Emergency Lights, that is, only a light source. The maximum number of lines received from emergency luminaires is 4, one lighting line, one charge/test line, one n line, one PE line

The charging/testing line is connected to the mains and the other end is connected with the battery of the emergency luminaire. As the name implies, this line has a dual effect, in the state of electricity to maintain power, this line is used for the emergency lamp's own battery charging, in the case of electricity loss, through the detection line, the mains of the 0-voltage signal to the battery, from the battery to the Emergency Lights, so that Emergency Lights, to achieve the start of Emergency Lights. This is the Emergency Lights in the charging/testing line after the power of the battery power to start the way. In order to ensure that the emergency lamp's own battery charging, this line is generally connected, that is, the state of electricity.

In peacetime/Qiangqi lighting Line's function is: in the non emergency condition, we may use this emergency lamp as the ordinary lamp regards and uses. In a non emergency state, the conductor connected with the two-control switch s static contact 1 is in an electric state, and the conductor connected with the dual-control switch s static contact 2 is in a state of electrical power loss. Dual-control Switch s (this dual-control switch is in fact a single control switch) can realize the lighting and quenching of this emergency lamp, hit the static contact first 1 when the Emergency Lights, static touch the first 2 emergency lamps extinguished. In the case of emergency and mains power, with the dual-control switch s static contact 1, 2 connected wires are in a state of power, this line will achieve Emergency Lights, this is the fire control room signal strong start way.

PE line is the case of Emergency Lights.

3, Qiangqi: The so-called strong-Kai, refers to the emergency state will be lit light (not emergency state light lighting is not called Qiangqi). Emergency Lights of the strong Kai is divided into two kinds: A, charging detection line loss of electricity, from the battery to the Emergency Lights; b, charge detection line charged, Emergency Lights power supply to emergency lamps.

This is a typical two-head light access method, the characteristics of the double headlights are: usually not bright, power outages or fire at a point in the light. Emergency two-head lamps start when power failure occurs. When the power outage, the charge detection line loses power, relay coil loses power, magnetic flux is 0, often closed contact point closed, the battery and emergency lights, lights light.

Fire but no power failure when the emergency of the start of the two-head lamps. When the fire, the contactor often open contact closed, resulting in a strong opening phase line electrification, to connect to Emergency Lights, to achieve the purpose of strong Kai. At this point, the relay coil to withstand 220V voltage, often closed contact point disconnect, with the battery and emergency lights off, batteries out of charge status.

What are the precautions for emergency lamp use?

1. Determine the installation position of the luminaire and the Power supply box, select the appropriate installation mode, and prepare the corresponding length of three-core cable and five-core cable.

2, use the M5 hex wrench to open the power box lid with the cable inlet, remove the ballast. will be prepared three-core cable at one end according to explosion-proof requirements from the Power box output to the ballast; and then the five-core cable one end from the power supply box input to the ballast; plug the battery wiring into the corresponding battery positive and negative connection (note: Red line to connect the cathode, black line to the negative), close the Power box cover and fixed.

3, according to the location of the fixed lighting and power supply box installed, use M6 hex wrench to unscrew the fastening screws around the front cover of the luminaire, open the front cover, connect the other end of the three-core cable to the luminaire, and then place the front cover fixed; the other end of the five-core cable line to the explosion-proof requirements of the mains, you can achieve lighting.

4, the Ballast Circuit board on the emergency function switch to the off position, can realize the lamp outside the control of the emergency function (if not required for line control emergency, only the switch to the on position, power failure can automatically realize the emergency function.

5. When replacing the bulb, unscrew the fastening screws around the front cover of the luminaire with the M6 hex wrench, open the front cover, rotate the old bulb to replace the new bulb, and then fasten the front cover.
