Security system magnetic contacts in vinyl windows?

We currently have magnetic plugs in all the ground floor casement windows connected to the hardwired security system.

How do you get this hooked up to a new vinyl window?
How does retro-fit vs. full frame affect this?

Thanks.

They can be hooked to retro contactor switches once the wire is pulled through the sill.

We, as a standard, have the customer coordinate with the security company because we do not want to accept the potential liability of that retrofit.

Pretty easy to accommodate though.

i would us a 3/8" press and fit switch in the vertical leg with a rare earth magnet on the sash. Should be enough clearance to do this and provide a fairly large gap.
