Truealert Es on conventional NAC or Power Supply

Hi all,
Does anyone know if a Truealert ES can be powered on a conventional Smart sync circuit or does it need a special command to sound from a IDNAC compatible panel? Reason I ask is because tons of Truealert Es are available on e-bay.

The ES is an addressable alarm.

It needs an IDNAC Signal from an IDNAC power supply, a TrueAlertES power supply (on the newer ES series panels) and needs an ES series panel because these are addressable devices.
