This article discusses the discrepancy between documented poll rates on an ITS-DX4020-G.
The Bosch Cellular Service User Guide states that for Fire applications we should go with a Poll rate of 240 Ack wait of 10. the current ITSDX4020-G O/I guide says Poll at 60 Ack wait 13. Which is correct?
240 seconds with 10 second retries is correct for the current NFPA72 regulations for Fire. This used to be 60 seconds in the old NFPA72 standard.
