What should I expect when I turn my A50 on?
When mains power is first applied to the A50, it requires a period of approximately 40 seconds to stabilise.
During this period all lights on the front of the device will flash on and off four times (accompanied by a sounding horn)
The OK lamp will then flash on and off while the Fault light remains lit
Once the device has fully initialised the Fault light turns off and the Ax 50 enters normal operation mode
The flashing OK lamp indicates the system is operating correctly.
