Accenta G4 alarm & garage door

[Petergmarsh]

I have an Accenta G4 alarm installed.
There are two key pads, one by the front door & the other inside the garage by the door. The garage is covered by an infra-red device and the door is Garador sectional door controlled by a Garamatic 10 motor & control. I understand that Garador can supply a relay that connects in some way to the infra-red device that enables you to raise the door without setting off the alarm. What Garador cannot tell me is how to connect to the alarm system.
Can anyone help?

If it's a simple relay then Google 'shunt switch'.

You need to find out how this relay will operate , but usually you would connect it across the garage detector NC terminals , so when you press the remote to open the door , the detector is bypassed ( or shunted) , giving you time to disarm the alarm.
