HVAC Trouble Conditions
When an SCS⁄SCE trouble condition exists, the type of trouble can be identified on the SCS⁄SCE modules by a series of one or more LED
flashes (trouble codes) as described in this section.

HVAC Module Trouble
A trouble affecting the entire SCS⁄SCE is called a module trouble condition. A module trouble may occur for any of the following reasons:
• Communication is lost with the FACP. All amber trouble LEDs will flash rapidly. During this condition, an annunciator communication
fault will be displayed at the control panel. (COMM LOSS)
Example: Trouble with the EIA-485 communication loop or incorrect address selection.
• Annunciator points 33-64
For AM2020/AFP1010 only: Annunciator points 33 - 64 are not programmed as type ID ACON and an SCE is not
connected or responding to the SCS. All yellow LEDs will flash rapidly. During this condition, an expander trouble will
be displayed at the control panel. During this condition, an expander trouble will be displayed at the control panel.
• NF2S-3030, NFS-320/NFS2-640 with NCA-2, or NFS2-3030 with NCA-2: Annunciator points 33 - 64 are not programmed to an
unused output point and the SCE-8 is not connected. All yellow LEDs will flash rapidly. (EXPANDER CONFIG)
