For 120 vac supply, connect the black lead to the 120 vac line wire (hot). Connect the ground wire from the power supply to a receptacle (e.g. a wall socket) that is not connected to an electrical outlet. This will allow you to turn on the light when you are not using it.

Can emergency lights be on a switch?
Emergency lighting operations maintained lights can be wired to a light switch to be used as normal room lighting and will function as emergency lighting during a power failure.
The control panel is located on the rear of the vehicle and is used to control the lighting in the cabin. The panel consists of two main controls, one for the main lights and the other for auxiliary lights.
This panel can also be accessed from the driver’s side door.
Does emergency lighting need its own circuit?
If you are in the US (National Electrical Code territory) the emergency lighting units should be fed by the same circuit as the lighting, but it must of course be connected to the main power supply. If you do not have a ground connection, you will need to use an extension cord to connect the unit to a wall socket.
What is the NEC code for emergency lighting?
Systems, covers requirements for emergency lighting. 700.16(B) states that emergency lighting systems shall be designed and installed in accordance with the provisions of this section. The following requirements shall apply to the design and installation of the lighting system: 1. The system shall comply with all applicable Federal, State, and local building and fire codes.
All lighting fixtures and equipment shall meet the requirements of NFPA 70.3. Each lighting fixture shall have a minimum of two outlets and a maximum of four receptacles. A fire extinguisher or other approved means of extinguishing the fire may be used in the event of an emergency.
If the system does not have an automatic shut-off feature, it shall automatically shut off after a specified period of inactivity. When a fire alarm is activated, the lights shall remain on for at least one hour after the alarm has ceased to sound. An automatic fire sprinkler system is required to be installed at each floor level of a building.
What is AC and DC in emergency light?
Lights run off an Alternating Current (AC) of 120 VAC supplied the building they are installed to. However the unit does not run on AC, but instead converts it to DC. This means that the lights do not need to be turned on and off as often as they would if they were on an AC unit.
The lights are controlled by a switch on the front of the light fixture. The switch can also be set to “OFF” to prevent the LEDs from lighting up when no one is using the room. If you want to turn them on when you are in a room, you can use a remote control to do so.
What cable should emergency lights be wired in?
What cable should be used for emergency lighting? A 4-core cable of the type widely used for lighting circuits that include self-contained (not central battery) emergency fittings. A fire resistant cable is required to connect the emergency light fitting to the circuit. The best cable is one that has been tested and approved by the National Electrical Code (NEC) for use in the United States.
It is recommended that you use a cable with a rated voltage of at least 3,600 volts to ensure that it will be able to provide sufficient current to meet the requirements of your application. If you do not have access to an approved cable, you should consider using a 3-pronged cable. This will allow you to use the same cable for both emergency and non-emergency lighting.
What is the difference between emergency light and exit light?
The lights are different from each other. (EELs) are designed to be used in the event of an emergency, such as an explosion, fire, or power outage. They are also used to indicate the direction of travel for emergency vehicles. EEL lights are usually located on the outside of a vehicle, but they can also be installed inside the vehicle.
How do emergency lights get power?
How emergency lights work. A small battery is charged by a fixture that is connected to the main power supply. Emergency lights are designed to be switched on and off in a matter of seconds. When the emergency lights switch on, they illuminate the area around them for a short period of time, and then turn off.
This is called a “flash” and can be used to alert the public to an emergency situation, such as a fire, or to warn people of an approaching emergency vehicle. Emergency lights can also be programmed to automatically turn on when a certain time of day has passed, for example, when the sun goes down.
