ANSI/IEEE Audible siren form
IEEE-library form of audible siren: a siren indication identifies an audible alarm output with the documented operating role.
In plain English
What does ANSI/IEEE Audible siren form mean?
This reference locates audible siren in Autodesk's IEEE-oriented miscellaneous family. A siren indication identifies an audible alarm output with the documented operating role. The public library uses HAN1S 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
State the alarm condition and the controlling circuit. The symbol alone does not prescribe tone pattern or evacuation meaning. State the alarm condition and the controlling circuit. The symbol alone does not prescribe tone pattern or evacuation meaning. 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.

How to read it
- State the alarm condition and the controlling circuit.
- The symbol alone does not prescribe tone pattern or evacuation meaning.
Information to show or reference
- Identify the associated device, circuit or diagram boundary.
- State the alarm condition and the controlling circuit.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
A distinction that matters
The symbol alone does not prescribe tone pattern or evacuation meaning.
