3.2.2 AV-AMP-80 LEDs
There are six (6) onboard LEDs associated with the AV-AMP-80 (see figure 6).
1. Transmit (TX): Flashes when sending data via USB or RS485 port.
2. Heart Beat (HB): Flashes to indicate proper microprocessor operation.
3. Amplifier 1 (AMP 1): On steady when amplifier 1 is active. Flashes on amplifier 1 trouble or open/short
circuit on amplifier 1 speaker circuit.
4. Amplifier 2 (AMP 2): On steady when amplifier 2 is active. Flashes on amplifier 2 trouble or open/short
circuit on amplifier 2 speaker circuit.
5. 40V: On steady when amplifiers are active, flashes during amplifier supervision test.
6. USB: On steady when amplifier message is being programmed (USB port connected).
3.2.3 AV-AMP-80 Amplifier Backup Programming
As previously discussed, both amplifiers (AMP 1 and AMP 2) of the AV-AMP-80 amplifier are controlled together.
However, based on installation or local code requirements, amplifier 2 (AMP 2) can be configured as a backup
amplifier for amplifier 1 (AMP 1).
Configuring amplifier 2 as a backup amplifier is done in the Axis
AX
AV-AMP audio message programming tool,
simply check the associated “Backup Mode Enabled” box within the Properties (see figure 7).
