The unit has as standard 32 recognised sounder tones and 3 levels of volume adjustment, all of which can be easily configured on site. Additional to the audible warning the unit is also fitted with a LED visual indicator for added warning capability. Utilising well-proven adaptive radio signal processing algorithms ensures the highest levels of life safety and reliability.
