Great video. After how many years would the siren's battery need replacing if ran in SCB mode? Cheers

Great video cheers. Do you know of a way in texecom premier elite to have a contact only alert if it is left open for a set time. IE scenario where you don't want it to alert if a gate is open then shut but if left open for say more than 10 seconds it alerts? Is that possible?
