Normally you have UPS per rack. That adds value as electricity splitter.
Will the unit blamed AC in your drawing be pulling air on top and blowing on the ground to help abuse natural circilation?
Normally servers blow hot air in the back FYI. I dont see that instrumented at all.

The UPS is centrally installed together with a generator, the air flow will be from down, the front of the racks will be faced to the AC unit.

Thanks,

wrong air flow costs you 1kW per rack 24x7

what about the sensors I mentioned, where are the best locations?

Thanks,

Do you have a better design that could be done with the same UPS and AC?

Thanks,

Each server has sensor or fifty, You will have tons of time to record them.

What I can suggest that you arrange air flows right. i.e cold air is blown in the face of servers from bellow and droppings are collected behind on top and front and back is isolated with slaughterhouse curitains.

Hi,

First of all it is preferable to have FM200 units out of the rooms. This is because if a fire occurs it might destroy the sensors or lines or worst cause the the tanks to explode. You also need to have control units and operating panels outside the room and make sure that doors are equipped with emergency panic bars. This is because FM200 gas removes the oxygen from the environment to extinguish any fire rapidly which is dangerous for humans. Should FM200 is activated it is preferable for people to control/override the operation from outside.

Then we come to other sensors.

General rule of thumb for cameras:
You generally use cameras to determine  who has accessed some rack/server and/or who entered the room. So that you could detect any unauthorized access to them. Cams should be placed on points where:
- You can record any person who enters/exits the room.
- Back/front of each rack so that you would know who had accessed to a particular/rack server at a specific time.

Humidity Sensors:
- If there's a water leakage it would most probably comes from the floor because you use FM-200 gas to extinguish any fire and your nozzles would not have any liquid. So the best place would be under the raised floor over the surface of the room.  They should be placed especially under the AC assuming that you're using precision A/C which utilizes water, and Racks in case there's a problem with water.

Smoke detectors would be placed over the ceiling close to Racks and the A/C.
