1.5 AFP-300/400 NION Diagnostic LEDs

The AFP-300/400 NION has 6 diagnostic LEDs used as aids in diagnosing proper operation.
Service LED - Indicates binding status of node on Echelon network.
• Slow blink indicates NION not bound.
• Off indicates NION bound.
• On indicates nonrecoverable error.
Network Status - Indicates status of Echelon network interface.
• Slow blink indicates network operation normal.
• Off indicates network interface not functioning.
• Fast blink indicates a network communication error.
Network Packet - Blinks briefly each time a data packet is received or transmitted on the Echelon network.
Serial 2 - not used.
Serial 1 - Application specific indicator of serial port activity (port 1); slow blink indicates the NION is operating
properly.
NION Status - Indicates status of the NION.
• Rapid blinking indicates proper NION operation.
• On or Off indicates critical error and that the NION is not functioning.

1.6 NION Power Requirements

The AFP-300/400 NION requires +24VDC @ 250 mA nominal and supervised battery backup in accordance
with local code requirements. It can be powered by any regulated, power limited source that is UL listed for use
with fire protective signaling units. The NION is equipped with a +3VDC lithium battery for data backup during
low power conditions. The AFP-300/400 NION is powered by external +24VDC supply at TB5.

1.7 Relay output - Fault Annunciation

TB6 on the SPB board is used to annunciate a trouble condition;
Normally Open and Normally Closed contacts are available.
The red Relay Power LED on the AFP-300/400 NION indicates a
trouble with either serial communication or Echelon network
communication.
