I have seen some routers have a plug you can plug a normal phone plug into and have other phones connected in the house on extensions so in theory won’t the Dailler work if the other phone work the same

I have a gardtec 816 and dailler will this Dailler work if I get full fibre broadband in house as it’s a digital line instead of a copper telephone line if not is there a way to make it work

I will get 2 new contacts and fit them and see how it goes does it sound like a contact fault it as been fine since

I have a 16 zone gartec alarm and working spot on last night a chime went and on keypad it said a door had been open I checked the doors and all ok there are 2 sets of doors on this zone both normal contacts set alarm as normal all ok would it be worth replacing the 2 contacts do there go faulty over time the system will be 18 years old thanks mark
