ANSI/IEEE Loudspeaker annunciation form
IEEE-library form of loudspeaker annunciation: a loudspeaker indication identifies conversion of an electrical signal to an audible output.
In plain English
What does ANSI/IEEE Loudspeaker annunciation form mean?
This reference locates loudspeaker alarm indication in Autodesk's IEEE-oriented annunciations family. A loudspeaker indication identifies conversion of an electrical signal to an audible output. The public library uses HAN1B7 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.
A simple example
Use the surrounding circuit labels and the project legend to identify the intended operating condition and connection. Carry the same device reference into the schedule or equipment document so the symbol can be reconciled with its real terminals, function and operating limits.
What the drawings help you do
Label the signal path and amplifier or system connection. An audio loudspeaker is distinct from a directly supplied with operating power alarm buzzer. Label the signal path and amplifier or system connection. An audio loudspeaker is distinct from a directly supplied with operating power alarm buzzer. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.

- Terminal
- An identified point where a conductor connects.
- Signal
- Electrical information passed between devices, rather than necessarily the main power supply.
- Rating
- A value stating the conditions for which equipment is specified.
