Two Minute Tuesday - Primary & Secondary Power Supplies

Life safety systems need two power supplies - a primary, and a secondary. Here we explain why you need them and ways that you can go about getting your secondary power supply. Enjoy!

Here at Sertus we manufacture smoke ventilation systems. We also like to educate people about smoke ventilation and related fire safety topics. Whether you're a smoke control pro or just someone who stumbled across our channel by accident, hopefully you'll learn something new and help us in our mission to make the world a safer place 😁
