ATG-3 - Signal generator
You will generate a light and acoustic signal even when power fails, because the built‑in battery keeps the warning in continuous operation.

// DESCRIPTION
What it is
The ATG‑3 signal generator emits an acoustic‑optical signal stored in the device's internal memory. You trigger it via one of 3 local inputs or by a simple power supply connection.
The optional internal battery maintains continuous device operation even during temporary power supply failures, so the warning signal reaches the crew without interruption.
