The SHM Delay App has no support for DLNA or Speakers. The Keypad_ExitDelay_Talker and SHM_Delay_TrueExit apps, produce Chimes and TTS on Lannouncer and TTS on speakers for the exit delay period. For entry delay I use a self modified version of Big Talker to Chime/Please enter your pin on the keypad/Chime along with keypad beeps and a siren chirp.
Recently learned of the Remind-R app that is similar to Big Talker but has a built in time delay capability.
Lannnouncer supports playing audio files. Perhaps you can use that capability with a Big Talker or Remind-R command to produce your desired sounds.
