And... if you are running software such as AHP, you could use the SH10A power horn as a chime with different tones and you can program the number of chimes.
Sending it a dim command has one tone and sending a brighten command has a different one. For every 10% of dim/brighten it makes a ding (I.E. 10% = 1 ding, 50% = 5 dings, etc.)
