Hello all. I'm a new Sundance user but have gotten many ansewrs here. My customer has a Dukane 24A700B Master Clock that has blown They have asked me to replace it. I have purchased a used unit but am in need of the program procedures. I have 30+ years in telecom and can use a manual. I've never had so much trouble finding a manual before. Any help/suggestions would be greatly apprecisted.

Is the Dukane company still making clock systems? Silly question, but I suppose you have already contacted them and asked them for a manual?

Dukane Communications is now owned by UTC. they bought the GE fire and security business in the last year or two.

Dukane does still manufacture clock systems. The current master clock is model #24A715. The Dukane 24A700B is long out of production, so getting support from UTC is going to be difficult to get.

What kind of secondary clocks are you running? Just about any master clock can run just about any model of secondary clocks. You may be better off returning the used Dukane 24A700B and getting a new, currently supported unit from someone else. We often use the model MC41LV from ATS in retrofit situations (https://www.ats-usa.com/overture/master_body.html). It works with a lot of different clock systems.
