The 2 front doors continue to act like they fall asleep. I test it every time I go to the site and never find a problem with it, the back door unlocks on the first prox read after periods of extended inactivity. During this whole time, the Honeywell reader on the back door has logged no complaints at all.I replaced those readers with some from AWID. I changed the reader/keypads again to a different manufacture, HID, I believe. A week or so goes by and the customer tells us that the same effect of the readers falling asleep is noticed. We install the P640 combination keypad/prox readers on those doors. After about 6 months the customer wants to change the readers to Keypad/Reader combo units on 2 office doors.The effect is like the reader falls asleep after about 6.5 minutes. If you present your fob again within about a 6 minute window the reader LED turns green and access is granted. I investigated, verified the complaint and discovered that if the reader stays idle (no reads) for about 6.5 minutes, the first presentation of the fob beeps the reader but its LED stays red and access is not granted. After a few weeks the customer told us that they had to present their prox fobs twice to be granted access sometimes.All were programmed and tested fine- cards read good, reader LEDs change from red to green properly, all works well as far as we can see. We installed 3 access controlled doors to the system, 2 with Linear P300 readers and 1 with a take out/used Honeywell OmniProx reader. I installed a Linear E3 Elite panel for a good customer in June 2016.I have never had this issue come up before. I have installed dozens of access control systems in that time, most of them Linear systems or their IEI predecessors. I started in the security field in 1985.Readers have been replaced/swapped and doors still behave the same way.
