In addition to this programmable button selection, the O9 Control Head has a dedicated "Hi / Lo" button on its Siren Mode Keypad.

 

WFForward.png The Hi / Lo Siren tones can also be enabled as one of a sequence of radio actions, known as Consolidated Actions. See also: Siren Type.

 

  • If the Siren is already on, pressing a Direct Siren function (Direct Hi / Lo, Direct Manual, Direct Wail, or Direct Yelp) that is different from the current selection leaves the Siren on and switches to the selected Siren function.

  • If the Siren is already on, pressing the Direct Siren function that is currently selected turns the Siren Off.
