Uninterrupted power supply in the case of fire, power outages or other electrical failures.
A fully charged battery backup should operate a standard size shutter 1-2 cycles over 1-2 hours period before it’s empty. This gives the user plenty of options when the power is off, supply interrupted or in case of an emergency or fire situation. Please not that even if the shutters are not used, the battery backup will still drain during power outages.
