Mirtone Service & Repair Forum
We have a mirtone EC200 installed in a 36 unit Sr. Care complex with standard call switches in each unit and a call light outside the entry door on the exterior of each unit. The system is powered with a 24VAC transformer. We would like to replace the outdoor lights with a Horn/Strobe combination unit to provide for better indication of the call request for emergency personnel. QUESTION: Can we replace the 24VAC transformer with a 24VDC power supply so that we can use 24VDC horn/strobes on the exterior of the buildings? All field wiring would be compatible with this but I wasn\'t sure if the EC200 would operate on a DC supply. 24VDC Horn/strobes are readily available but 24VAC ones (especially when they have to be weatherproof too) are extremely hard to find and are very expensive. Any input would be appreciated.
