Vistronic MCM 140 keypad not working

[lmor1]

My vistronic MCM 140 keypad has stopped working, when I try to put my code in to arm my system, it beeps and the led turns red after the third press of the digit keys, so cannot out my full code in. I have changed the battery but still no joy. Any assistance would be great

I assume this MCM140 is connected to some obsolete one way Powermax thing?

It could be out of range, lost it's programming/ faulty. Only seen one it was a pain...

As usual with the old Powermax stuff delete and re-enroll can fix or it maybe for the bin.

prove a range issue by taking the device to the panel. Have had local interference affect devices in the past

Hi, the keypad is connected to a powermax complete system and has been working fine for the last 6 years. I can’t enroll it again as I would need the installers code to go through the menu. I did try going through the menu to enjoy keyfob and when the system transmitted, I pressed the keypad keys and no change on the main control panel.

try the above before reenrolling.

Just because its been working for x years doesnt mean it will never stop. Imagine saying to the garage that their cant be anything wrong with your car that just broke down after 6 yrs of trouble free use

Have you tried asking the installer? I was assuming DIY.

[james.wilson]

I was too

Thank you for the comments, James I tried removing the batteries, reinstalling them and trying to connect to the system but the system still says transmitting and not picking up the keypad signal. 
 

I did contact the supplier, however they are wanting a fortune, so just thought it was a simple fix I could do. Looks like I maybe need a new keypad anyway.

Training engineers and running a business 24/7 to fix this stuff costs money. I don't know what a fortune is relevant to what you are protecting.

If you think they are trying to rip you off then see if someone else will take over the system. Although you will do well to find somewhere that wants to take it on without recommending replacement.
