Horizontal sliding door

[codequestion]

I have automatic horizontal sliding door which per IBC 2015 requires standby power. IBC says refer to NEC for standby power. I am confused as to what tyoe of standby power is required by the code generator, battery, UPS for the horizontal door????

I do not know what the 2015 IBC specs however, most all sliding doors that I have seen do not have backup power of any kind, they have push bars, breakaway hinges (and a lot of warning signage) so they can be opened manually from the inside for emergency egress..

As a matter of safety, I would tend to think that any exit doors that must be unlocked or opened electrically would be on a legally required emergency standby system, unless you are working on some sort of specialty item, like a bank vault, prison, or biohazard lab.
