Everspring Siren & Doorbell difficult to configure

I bought both Everspring Siren SE812 & Door Bell TSE03. Could include them in to Vera2 but cant make them perform. Vera initially configures both with device File as “D_Siren1.xml” and provides an ‘ON’ ‘OFF’ control on the Dashboard UI5. But they both fail to work and gives an error message “Transmit failed with error code1”. I have ensured that batteries are new and the Devices kept close to Vera2 for testing and before posting here in this topic. I tried changing Device File to D_BinaryLight1.xml with nill results. I am really stuck with these things after spending long hours trying. Has any one here used this stuff and could make it work? I would be much thankful for how they did it.
