I must say trying to help someone do their homework when I failed to do my own is not a good look at all.

I noticed you do this to my threads only. Anyways trying to point which code or article or sharing knowledge is not called homework.

I already did my homework but was not able to find it.

In NYC:
907.2
In all occupancies where an automatic fire alarm system is required, selective coverage smoke detectors shall be located as follows, unless partial or total coverage automatic detection is specified.
1. In each mechanical equipment, electrical, transformer, telephone equipment or similar room, in elevator machine rooms, and in elevator lobbies.

You can't leave, you don't have a hall pass nor have you passed the departure test!
Stay put, we enjoy inspectors input!

As Victor points out, any requirements will be in the building code or local amendments thereto. Or the specs and drawings, which can go above and beyond code.

Or in NFPA 72.

As mentioned, you need to look in the adopted building code for the jurisdiction you are working and determine from the occupancy type if it is required.
For example, if it was the 2021 IBC and a Business "B" Occupancy (non-high rise), then no detectors are required per section 907.2.2.

NFPA 72 tells you how to install detectors, not if they are required.

Oh yeah

Yes, once you determine detectors and the associated control panel are required for the occupancy / facility from the Building Code, then you can go to NFPA 72 to see the how, that you need to put a detector at the control unit, power extender, etc.
