DOL remote start stop

Hi all. Apologies if formatting is off, creating on mobile.

Got a customer who wants to remotely control a DOL for their sprinkler system, currently the operators have to leave their station, down a flight of stairs then lean over a barrier (supposed to go round) to switch it on. Not much, but enough for them to ‘forget’ to turn them on a lot of the time. It’s a recycling facility, so in dry spells they’re incredibly dusty and get a lot of complaints. Their thinking being to get 2-3 remotes so the operators can switch on from the station, and also one or more managers/supervisors have office access to a remote.

Has anyone come across anything like this before? This is all I’ve come up with as a proper kit so far: https://toughleads.co.uk/products/stand-alone-remote-control-switch-for-dol-motor-starters States it’s for extractors but I can’t see a reason why that couldn’t operate a water pump(?).

Or does anyone have any other clever ideas? Using a kinetic wireless switching setup to pull the contactor in? Interested to hear thoughts.
