Police Station 911
Police Station 911
(OP)
I was asked to review a possible upgrade of an existing standby natural gas generator at a small police station in Massachusetts. Currently the required life safety lighting and fire alarm system is battery back up and this generator was added some years later. Over the years branch circuits have been added to this generator to serve air conditioning, computers, outlets, and to their 911 call system.
I am not familiar with any codes regarding 911 and was curious if this system should require a separate branch (ATS)from this generator or future upgraded generator. If 911 is considered as a life safety branch would the single source natural gas feed be acceptable or should diesel upgrade be considered as well as MA 2 hr ratings for equipment and feeders.
I appreciate any help.
Thanks.

It is a national standard that is available for guidance.

The existing engine is an Onan 45KW, I would like to upgrade to a 60KW and have it fit the existing foot print in the basement. Cummins can accomodate, but the issue has now surfaced that they no longer provide a city water cooled engine and that a remote outdoor radiator will be required.
I am leaning on moving the entire system outside within an enclosure and make the fuel source diesel.
