Hi, I just replaced my old Veritas 8 control panel with the same Veritas 8 new one, a new back up battery and Premier Odyssey 1E external sounder. Everything functions as before except one thing. When I set the system and exit, the external sounder rings for 5 seconds. Before the external sounder LEDs would flash to indicate the system was set but the sounder remained silent. Does anyone know how I can silence the external sounder when setting the system please?
