What does audible alarm mean?

What is an audible alarm? Audible alarms produce loud noises and are used to draw attention to an upcoming action. Mostly, audible alarms serve to warn of imminent dangers in areas where visual indications cannot be used sufficiently to alert people.

Where would an audible alarm be most effective?

In an enclosed space some of the sound will be reflected and increase the sound level. All-mounted sounder is positioned near a ceiling, more sound will be reflected. The same is true for a ceiling mounted sounder near a wall. A sounder mounted on a wall is more effective than one mounted on a pillar.
