Our Fire Alarm Internal communications Systems is Mirtone with 3 major components,
Master Hand Set-Fully functional '
Amplifier Model QSE-222,
Supervisory Controller, Model QSE002
Either the amplifier and or the controller are disfunctional.
The manual that we have do not have detailed circuitory drawings for the Amplfier or the Controller.
These items are approx. 33 years old. We are in Edmonton, Canada.
Mirtone Fire Alarm Co. is defunct in Canada and thus very little assistance if any is available in solving the problem.
We wonder if you can offer us any assistance as to where we could find the detailed ciruitory drawings for the Amplifier and the controller.
We thank you for your assistance.
