Emergency Floodlight With Stand are commonly installed to cover the final exit points of public or commercial premises, especially when those final exits lead out to areas which are dark at night. It should be noted than when risk assessing a final exit route, care must be taken to account for a worst-case scenario. For example, you cannot assume that a neighbouring property will have their lights on, or that everyone leaving the building will be familiar with their surroundings.
For some premises, it is advisable to install maintained emergency lighting which is always illuminated. This presents a particular advantage if the exit also serves as an entrance point and is frequently used, however, this is not always an ideal solution.
When commercial or public buildings are located in populated areas, light pollution can be an issue for neighbouring properties. Where this is a concern, it has been common practice to make use of non-maintained emergency floodlights covering escape routes.
Both of these options have drawbacks. Non-maintained emergency lighting will only illuminate when there is an emergency involving the loss of regular mains power, but this accounts only for one escape scenario. If a fire or a physical threat causes the evacuation of the building when it is dark outside, a non-maintained light would not come on until the power supply is compromised.
A relay-activated system could be considered as well. This allows for emergency lighting to be triggered by an impulse from a relay such as a contact sensor on the exit door, or a signal from a fire alarm panel. Whilst relay-triggered devices are a solid option, they are generally more complex to install as they require the addition of hardware to the door in question, or a physical connection to the fire alarm system, which can be expensive to achieve. Again, if the installed light is triggered by a relay from a fire alarm system, there is a risk that the floodlight may not illuminate if the emergency that causes the evacuation does not involve a fire.
