Fire Exit Signs, also called Fire Escape Route Signs must be visible, even when
the power supply to the normal lighting fails. Illuminated fire escape route signs
and fire exit signs fulfil this requirement. The minimum backup duration of emergency
lighting is specified by local regulations and is generally between 1 and 3 hours.
All our units have a 3 hour internal battery. Self-contained escape route signs
and fire exit signs are classified according to their modes of operation. Click here for more information on the modes of operation for emergency lighting.
