Bought myself a Jablotron JA-83 panel. The manual advises to connect only 1 wired keypad (JA-81E). Additinional keypads should be connected wireless. Does anyone have an idea why ? Is this panel not able to work with 2 keypads on the same keypad connectors? Does the panel delivers not enough power to feed more than 1 keypad? Or does Jablotron likes to sell wireless keypads above wired ? I really would like to know why...
