I've researched for hours trying to figure out the control wiring of this circuit. I'm at a loss and I certainly need help.
BACKSTORY
Residential community has a community center with three separate bodies of water---main pool, wading pool, and spa. Sub-panel service is 120/240v. Equipment, for reference, are (4) separate pump motors with (1) emergency shut off switch. Motors identified below:
Main Pool Filter Motor - 2.0 HP, 208-230v, 60Hz 1PH kW, 11.0-10.2 MaxAmps
Wading Pool Filter Motor - 1.5 HP, 208-230V, 60Hz 1PH kW, 9.6-8.8 MaxAmps
Spa Filter Motor - 2.0 HP, 208-230v, 60Hz 1PH kW, 11.0-10.2 MaxAmps
Spa Booster Motor - 3.0 HP, 208-230V, 60Hz 1PH, 14.6-12.7 MaxAmps
SCOPE
Currently, the emergency stop switch (DPST toggle) operates just the main body of water. Community manager would like to have all (4) motors/pumps shut down if the emergency push button is engaged.
SOLUTION
I've attached a wiring diagram of how far I've gotten.
For those whom are much smarter than myself, can someone help me out? Give some guidance on how to complete the control wiring?

SCOPE
Currently, the emergency stop switch (DPST toggle) operates just the main body of water. Community manager would like to have all (4) motors/pumps shut down if the emergency push button is engaged.
SOLUTION
- Remove existing DPST toggle emergency stop switch.
- Install a dedicated 15A, 120VAC circuit from the service panel to an ESO push/pull button switch.
- Normal operations: ESO push button pulled out (closed), energizes NO Relay #1, closes contact, energizes (4) 120V control coils of pool pump power relays to close contacts and motors operate---no audible alarm.
- Emergency operations: ESO push button pushed in (open), de-energizes the NO Relay #1 to an open state along with the power relay contacts of the (4) pool pump power relays---audible alarm needs to sound.
