Q. What is the difference between the DC1 and DC2 inputs on a LifeSafety Power FPO power supply? PDF Print E-mail
A.  The DC1 output on an FPO power supply is a continuous, non-controllable output, while the DC2 output can be controlled with the FAI input.  By setting the DC2 output’s fuse to the appropriate setting, the operation of the DC2 output can be changed from failsafe to fail-secure.  If FAI is not used in an installation, the DC2 output can be used as a continuous output as well.
