I am trying to connect a GXW4224 gatway between a UCM and 24 Code Blue IA500D emergency call stations without success so far. The problem, according to Code Blue is that the GXW does not provide enough power out to the door stations to allow them to work.
So far Grandstream has been unable to provide me with what power output (loop current) is, but Code Blue states previous testing has found this to be a problem.
This is a new area for me, so help here would be appreciated.
Does anyone know what the line voltage on the GXW is?
Does anyone have a suggestion as to how I can boost the line voltage between these devices?
Although I would prefer to say with Grandstream, does anyone know of a gateway with more power I should loiok at?
Any other thoughts, ideas and/or suggestions?
