Brad06 Posted January 25, 2022 Report Share Posted January 25, 2022 We have a customer that has a Tunstall nurse call system throughout the building and has smoke alarms linked into each speech unit in each flat, this is powered from the Tunstall unit and has back up battery in each smoke. would this be classed as a grade D fire alarm within the flats? I would argue not as they are not mans powered. if not what grade would this be classed? Quote Link to comment Share on other sites More sharing options...
AnthonyB Posted January 27, 2022 Report Share Posted January 27, 2022 Are they wired into the Tunstall or wireless linked? Usually you either see Grade D1 third party equipment with a relay base to the system or Tunstall's own Grade F1 wireless detectors (if a newer set up) Could be grade C depending if there is basic fault monitoring. Difficult to say to be honest without looking Quote Link to comment Share on other sites More sharing options...
