I recently bought an ACT-707SE and ACT-707T, which worked great for about 30mins, then the audio disappeared with no warning, and, although the rf is still fine, I cannot get any audio signal. Could you possibly help as nothing I do seems to make any difference at all. Many thanks in advance! All the best, yours, Colin Veysey.

I have a ACT=707SE unit. whenever I use my wireless mic with this unit, and whenever I am more than 5 feet from the receiver, I get dropouts really bad. and sometimes I can be less than 5 feet from the receiver and have the transmitter on the other side of my body and it will not have a signal. The gain is set right, and I have new batterries in the transmitter. What can be the cause of this.Thanks in advance,Birdo

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?

: Our industrial unit, a large-scale packaging facility, has been experiencing a consistent issue with the conveyor system. The belt constantly breaks down, causing significant delays in product packaging and resulting in lost revenue. This leads to increased labor costs as were forced to manually sort packages. The current estimated repair cost is high, likely exceeding $50,000, given the complexity of the machinery involved. Given this ongoing problem, Im concerned about a long-term solution to prevent these frequent breakdowns and maintain our production capacity.:

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 wasnt 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.

Based on my previous experience, the MITSUBISHI PD21B CNC module might be experiencing intermittent power loss resulting in frequent system freezing during operation. This could indicate a potential issue with the power supply or internal connections. Further inspection by a qualified technician is recommended to identify and address the root cause of the problem.
