Schooner Intercom

Hi There,

I have posted a video of my 5 pin Intercom below

…and a technical doc describing it here

http://www.intercomsrus.com/handset%20pdf/Schooner%20Door%20Entry%20Handset%20Data%20Sheet.pdf

I’d love to be able to link an Opener to this, but I need to be sure before I buy?

Can anyone help?

Thanks.
