China Emergency Light Manufacturers , Emergency Light Switch Wiring Solution
China Emergency Light Manufacturers mainly introduces the switch wiring of several emergency lights.

  
1. Fire emergency light switch wiring

  
For emergency luminaires that only contain emergency light sources and have their own batteries, they contain only one light source. There are 4 wires from the emergency luminaire, one lighting wire, one charging/detecting wire, one N wire, one PE wire, and the wiring of the emergency luminaire: Let us first say that only the emergency light source is included. The emergency light fixture with its own battery contains only one light source. There are 4 wires from the emergency luminaire, one lighting wire, one charging/detecting wire, one N wire, one PE wire.

2. Emergency light single control switch wiring

  
The two contacts of the two single-pole double-throw switches are respectively connected, that is, the contact 1 of the switch 1 is connected to the contact 1 of the switch 2, the contact 2 of the switch 1 is connected to the contact 2 of the switch 2, and then the two switches The knife is used as the two ends of the entire switch to access the ends of the lamp. Thus, when the switches 1 and 2 are simultaneously connected to the respective contacts 1 or simultaneously to the contacts 2, the circuit is turned on and the lamp is turned on.

  
If one of the two switches hits the contact 1 and the other touches the contact 2, the circuit fails, and the light is off. Therefore both switches can control the lamp. Two switches can be placed at the upper and lower ends of the stairs, or at both ends of the corridor, so that you can turn on the lights before entering the corridor, turn off the lights at the other end through the corridor, which can both illuminate and avoid the waste of the lights. Electricity.

  
3. Emergency light double control switch wiring

  
Let’s first get to know the wire color of the dual dual control switch. Red represents the fire line; blue represents the zero line; green represents the round line. After you know the color of the wire, let’s start wiring.

  
First connect the middle terminal of a dual control switch to the live wire, then connect the middle terminal of the other dual control switch to the base (or the center tongue of the screw base), and then connect the return line, that is, use two green The wires are arbitrarily connected to the upper and lower terminals; the neutral wire is directly connected to the other contact of the lamp cap (or the thread of the screw cap) so that the connection is completed.

  
4. Bring your own battery emergency light switch wiring

  
The common control and wiring of the self-contained battery emergency lighting fixture is compared with the ordinary lighting wiring. First, a control line and the main contact of the AC contactor connected in series are added to the outlet circuit, and the charging circuit is used for the charging circuit. protection.

  
Although there are many ways to control the emergency lighting, the principle is the same. When the manual button is pressed, the contactor coil KM is energized, its normally open contact is closed, the contactor is self-locking, and the lamp is turned on. Bright; when automatic, the fire automatic alarm linkage contact K is closed after receiving the signal from the fire detector, so that the contactor coil KM is energized, its normally open contact is closed, the contactor is self-locking, and the lamp is illuminated. When the light button S2 is turned off, the contactor coil loses power, its normally open contact is restored, and the controlled light is off.

  
5. Common emergency light wiring method

  
Under normal circumstances, it is a fire wire, a zero wire, and a ground wire. These three wires are the wiring method of conventional lamps, and another fire wire is taken from the corresponding distribution box to the emergency lamp to be connected to the charging power source. In this way, after the distribution box circuit switch trips, the emergency light can be illuminated by the rechargeable battery and brightened while being charged; or the rechargeable battery can be kept lit for a certain period of time after the fire distribution box is cut off.
