TrueAlert ES is the addressable notification family for Simplex 4100ES, 4010ES, and 4007ES panels, where each horn, strobe, or combination appliance carries its own address rather than wiring as a conventional notification appliance circuit. Addressing the appliance directly lets the panel set tone and output on a per-device basis, supervise each unit, and report load at the appliance, which simplifies circuit design and survey verification compared with conventional NAC wiring.

Verify panel and device family compatibility before ordering.
