Hi.
My name is S?lvio Viana and I'm a Brazilian Electrical Engeneer.
My Company, called Somitec Automa??o, is begining to work with Fire Alarm Systems. I'm working with a project and I got some doubts about some topics and I'll be sincerily thanks if you can help me:
1- Can I pass, in same conduct ou raceway, the comunication looping circuit Class A (signaling line circuit for initiating devices) with the 24 VDC line thats feed the "alarm signal" (strobs, horn-strob etc). Both circuits will be conected to one Adressable Control Unit (Panel)?
2- Untill now I don't understand the diference between PLFA and NPLFA circuits. I know that it means POWER LIMITED AND NO POWER LIMITED FIRE ALARME circuits. But I didn't understand how to recognize them. The loop class A of initiating devices is a PLFA circuit? The line VDC that feed the strobs e others kinds of alarms is a NPLFA circuit?
Thank you for your atention and forgive me about my not very good english.
