I am looking for any literature or information anyone may have, related to my Dunbar Nunn Unitrol Model 330-55 Switchbox.


Also, any hint of when my switchbox may have been manufactured would be appreciated. The serial number on my switchbox is 3-12211.


I understand that Federal Signal acquired the Unirtol line from Dunbar Nunn line on January 1, 1996.

Did you ever have any luck finding any information or wiring diagrams for this switch panel? I just obtained one also and can't find squat about it.


Thanks
 
PM me your email, I have the manual in PDF and can email it to you. I like those boxes a lot- intuitive and work every time.
