The SCS⁄SCE
Configuration
Switch Group LEDs for FSCS Mode
FSCS Toggle Switch Group LEDs
There are three LEDs associated with each SCS⁄SCE toggle switch. These LEDs function according to Table 3.8.
FSCS 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.
FSCS 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/Network Annunciator. All amber trouble LEDs will flash rapidly and the piezo will sound.
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
All yellow LEDs will flash rapidly and the piezo will sound.
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. During this condition, an expander trouble will be displayed at the control panel.
NFS-320 or NFS2-640 with NCA-2: Annunciator points 33 - 64 are not programmed to an unused output point and the
SCE-8 is not connected. During this condition, an expander trouble will be displayed at the control panel.
