ELK Defintions:

MilliMiser™
This exclusive option allows further reduction of current draw (25% current draw reduction with only 6 - 8 % reduction in volume). It is great for controls that have limited alarm or auxiliary output power.

ComboTrigger™
This unique feature produces two distinct sounds, even from controls that have a single alarm output with a pulsing option for fire or burglary.

VolumeStep™
This exclusive feature is best described as a "peacekeeper." It allows the installer to select to start the message at a low volume which gradually rises over 90 seconds to full volume.
