Wiring a Bathroom Exhaust Fan

Electrical Question: I have a Fantech inline exhaust fan, I want to wire separate switches in two bathrooms to control the same exhaust fan.

How to Wire a Inline Bathroom Exhaust Fan

Tony asks:
I purchased a Fantech PB270L10 2 Bath Fan w 2x LED to exhaust two separate bathrooms.
On a dedicated circuit, I want the wiring such that if someone in bathroom #1 turns the fan on (note, it will exhaust both bathrooms simultaneously) I don’t want someone entering bathroom #2 to hit the fan switch and turn the fan off this is my problem with using 3 way switches.
However, if both switches are in the off position, the fan will be off.
I have done tons of internet searching and a few blogs have said to use single pole switches wired in parallel so that either bathroom switch can turn the fan on, but no one can turn the fan off accidentally while someone is still using the other bathroom.
Is this safe and up to code.
I am attaching a hand drawing of the circuit that I want to wire the grounds are not shown in the drawing.

Additional Comments: Lots of useful information for the novice such as myself.

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
