Egress During an AC Loss Featured

Wednesday, 11 March 2015 12:46 Written by 

Are you in a region that requires egress doors to unlock on an AC loss?  Typically, this is accomplished by simply not placing a backup battery set on your 24V lock power supply and using fail-safe locks.

But what if you have other locks or 24V devices you want to remain powered during an AC loss?  What if you are using fail-secure locks that need to unlock on a loss of AC power?  LifeSafety Power has a more elegant solution that offers more flexibility.

By simply integrating the AC fault relay into the FAI input circuit of the FPO power supply, you now have full control over what happens during an AC power failure using standard FAI-capable outputs.  This includes selecting which doors unlock and which don't for both fail-safe and fail-secure locks.  It also allows you to select outputs to remain powered during an AC loss.

For wiring diagrams and more information on this, see our Application Note AN-28.  And as always, our Technical Support department is here to help.
