Sound warning for a temptress? (5)

I believe the answer is:
siren
This clue could be a double definition.
'sound warning' is the first definition.
'siren' can be an answer for 'warning' (I've seen this before). I am not certain of the 'sound' bit.
'temptress?' is the second definition.
(synonyms)
'for a' acts as a link.
Can you help me to learn more?
(Other definitions for siren that I've seen before include "Temptress - makes a loud noise!" , "'Delilah!'" , "Loud warning signal" , "Loud whistle or dangerous woman" , "Alarm; temptress" .)
