I am repairing a door lock at an apartment block showing these symptoms.A transformer feeding the MA-485 is outputting 19.25 volts...will this harm the unit.It is a 16 volt amplifier.B when an apartment station depresses the door button the output at the amplifier terminals for the ac door reads 19.25 volts...but when it is released it only drops to 18.85 volts...which makes me think the relay is stuck on the amplifier.....bottom line do I need a new controller?C the electric strike shows a rating of 24 vac? how could this function well on a 16 volt system?It appears to have been part of this system for some time..and the caretaker has said there are problems with the system as far as people getting in without being buzzed. what is the lowest voltage a 24 volt buzzer could activate at?— Purchase or Repair:

Mircom Intercom Amplifer -MA-485 do,s not have any audio sound aplification needed to operate an apartment intercom station . I beleive when the oringinal split transformer 8v for door and 16 vac for the audio burned out because the pos+ side came lose and grounded to the neg - side the replacement was a 120- AC 24 volt 1.67 Amp 40 that I believe it damaged the amplifier circuit leading to no sound at the intercom station.Please correct me if Im wrong at my way of thinking. leewright— Purchase or Repair:
