Hi, hoping someone can help.
I have an original BT VP1000 Home Monitor unit which I understand is a re-badged Visonic PowerMax.
I recently (March 2017) added a new wireless keypad (MCM-140) which has been working perfectly - however on a couple of occasions the main unit has reported a fault that it is unable to communicate with the keypad and then sends out alerts. I am able to clear the alert from the main unit by arming/dis-arming the alarm from the MCM-140 and all is well for a while.
I'm guessing that the main unit and keypad communicate with each other at a set time-frequency (for checking purposes) and for some reason this is being interrupted. Does anybody have experience with this type of set-up? Could it be as simple as a new battery is required?
Many thanks in advance.
