This is a luminaire in which the emergency lamps are lit all the time. In places of assembly such as theatres, cinemas, clubs, the emergency lamp is usually turned on only when it is necessary to illuminate the interior of the building. In the case of an emergency, the lights may be switched on and off by means of a switch in the centre of each lamp.
This switch can be operated by the operator or by a remote control. When the switch is operated, a signal is sent to the control unit, which in turn sends an electrical signal to a relay which turns the lamps on or off, depending on whether the signal from the relay is positive or negative.

Does emergency lighting need to be hardwired?
Emergency lights need to be on for 90 minutes if the electricity goes out. The electrical supply needs to provide power within 10 seconds of the loss of normal power. Egress lighting must be “hardwired,” or served by an automatic shut-off system. In the event of a power outage, an emergency light must remain on for at least 30 minutes.
Do emergency lights need their 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.
Is a maintained emergency light always on?
Emergency lighting should be on all the time. Emergency lighting should always be connected to the power source, but not always on. It can be turned off when it is not needed, or turned on only when needed. You can do this by turning the lights off in the morning, and then turning them on again at the end of the day.
If you do not have an emergency light in your home, then you can use the following tips to help you determine when you will need them: Turn off all lights that are not essential to your life. For example, if you have a lamp that is only used to light up the living room, turn it off at night.
Do not turn on a light that you use to read a book or watch a movie, because you may not be able to see what is on the screen or in front of you. The same is true for lights in bedrooms, bathrooms, closets, etc. Turn on lights only if they are necessary for your safety or the safety of others.
Does emergency lighting have to be wired in fire rated cable?
I’m well aware that emergency lights must be wired from the local lighting circuit and if from a central battery source the cables must be fire rated, if the lights are self contained then the cable should be rated for a minimum of 1,000 volts.
How do emergency lights get power?
The lights are powered by the main electrical supply and have a battery-powered backup. Emergency lights that only light up during emergencies or when the power is out are non-maintained. Emergency lights can also be used to warn other drivers of an approaching emergency vehicle, such as a police car, fire truck, ambulance, or other emergency service vehicle.
