Are there any built in tests that I can use to check the lights and horn work on my device?
The O2NE+ and Safe-Ox+ have a user initiated built in test which allows users to check the lamps and horn work
Momentarily pressing the 'Mode' button on either Ax O2NE+/ Safe-Ox+ or and alarm repeaters, in the absence of any alarm conditions, causes this test to be performed. The indicator lamps will flash 4 times and the buzzer will sound.
Please watch the video below for a brief demonstration:
