To tie their Dakota Alert driveway alarm system in with an exiting DSC alarm system some customers have connected the DCR-2500 receiver (which has relay outputs) to the DSC sensor. In trouble shooting it’s been found that because the DSC sensor¬†and the Dakota Alert system operate on 433mhz this can cause interference, causing the DSC sensor to¬†not recognize the relays change of state.

How to fix this?

Simple, move the DSC sensor further away from the DCR-2500 receiver (several feet if possible). This will help limit any potential interference from the wireless signals.
