How it works

- Signal processing: the ERA-DCRX receives the alert, plays the programmed melody, and activates the 12V DC output.
- Alert activation: the output powers the connected accessory for a set duration, with multiple alert combinations available.
Zone configuration examples
Different alerts per door: front door on Zone 1 with a blue strobe, back door on Zone 2 with a red strobe, loading dock on Zone 3 with a siren, side entrance on Zone 4 with a bell.
