Function-retention boxes
By retaining the function of electrical systems, we mean that they remain operational even in the event of an emergency or fire. Function boxes are also part of these systems. This ensures that the power supply to electrical equipment such as lighting, lifts, flue gas extractors, alarms, etc. is maintained for 30 (E-30) or 90 (E-90) minutes. This is enough to keep people out of the building and rescuers to work in the event of a fire.
