The SCS⁄SCE
Programming
•
Dipswitch positions 1 - 6 are OFF (factory default setting). All green LEDs will flash rapidly and the piezo will sound. During this
condition an expander trouble will be displayed at the control panel. Pressing the Local Acknowledge/Lamp Test switch will silence the
piezo. (DIP SW DEFAULT)
•
For SCS v4.0 or higher (requires NFS2-3030 and/or NCA-2 v.21 or higher); Dipswitch position 6 (HVAC/FSCS) does not match the
panel configuration in ACS programming (HVAC/FSCS). (MODE CONFIG)
HVAC Toggle Switch Group Trouble
A toggle switch group trouble condition applies to a single toggle switch and its four annunciator points. HVAC toggle switch group trouble
conditions are defined as follows:
•
A trouble condition exists for one or more of the four devices programmed to annunciate at that specific toggle switch. The respective
trouble LED will blink once, followed by a pause, then repeat until acknowledged. (DEVICE TROUBLE)
Example: Open circuit or loss of communication with a module.
•
For AM2020/AFP1010 only: Annunciator software type ID does not match the associated toggle switch function. The respective
trouble LED will blink twice, followed by a pause, then repeat until acknowledged. During this condition an external trouble is
annunciated at the control panel.
Example: A1P1 is AMON but should be ACON since the first annunciator point associated with the first toggle switch in
the SCS⁄SCE is expected to perform a control function (i.e. AMON programmed for a control point).
•
NF2S-3030, NFS-320/NFS2-640 with NCA-2, or NFS2-3030 with NCA-2: (Similar to the AM2020/AFP1010). Annunciator point is
not mapped to a device of the proper type ID.The respective trouble LED will blink twice, followed by a pause, then repeat until
acknowledged. During this condition an external trouble is annunciated at the control panel. (DEVICE MISMATCH)
Example: A1P1 is mapped to point N1L1M1 (monitor) but should be mapped to a valid “control” module.
•
Annunciator point activity or trouble occurs for an annunciator point which was not programmed to be active according to the group
type. The respective trouble LED will blink three times, followed by a pause, then repeat until acknowledged. During this condition an
external trouble is annunciated at the control panel. (DIP SW MISMATCH)
Example: A group is programmed as type 10 (CON
ON⁄OP
and VER
ON⁄OP
), but the off control point indicates an invalid
reply. Check group programming and annunciator point mapping.
HVAC toggle switch group troubles are acknowledged by pressing the Local Acknowledge/Lamp Test switch, at which time any flashing
trouble LEDs will turn on steady. The LED group trouble codes may be reset by pressing the Local Acknowledge/Lamp Test switch for at
least five seconds. When the trouble is cleared, the respective trouble LED will turn off.
3.9 Programming
3.9.1 NFS2-3030, NFS-320, NFS2-640, and NCA-2
Any mode of operation for SCS modules can be used when the modules are installed:
•
on an NFS2-3030 ACS circuit and linked to NFS2-3030 monitor and control modules;
•
on an NCA ACS circuit for use with NFS-640 and linked to the NFS-640 monitor and control modules using the network annunciator
menu or the Veri•Fire Tools Programming Utility.
•
on an NCA-2 ACS circuit for use with NFS2-3030, NFS2-640 or NFS-320 monitor and control modules using the network annunciator
menu or the Veri•Fire Tools Programming Utility.
Prior to programming, the following steps must be taken.
1.
SCS modules must be installed on the ACS circuit, then configured. (See Section 3.4.7, “Dipswitch Setting” and Section 3.4.8, “EIA-
485 Addressing” of this manual.) Using Worksheet 2 at the end of this manual, note the switch group type assigned to each switch
group.
2.
Using Worksheet 2, assign each SCS annunciator point a value of “needed”, “unneeded”, or “unused”. “Needed” points are those within
each switch group of four annunciator points that match the capabilities of the switch group type. Those points classified as “unneeded”
do not match the capabilities of the switch group type. “Unused” points are associated with switch groups that are not used. It will be
necessary to know these values for programming.
NOTE:
The NF2S-3030 and NCA-2 each provide 32 more annunciator points (points 65 - 96) per FSCS mode annunciator address than
legacy panels. Any or all of these extra points may be used to activate FSCS mode priority from the NFS2-3030 or the NCA-2. When one of
these points is programmed to a panel zone containing smoke control points, or to a single smoke control device, activation of the zone or
device will cause subsequent automatic events to be locked out. Smoke control can then only be overridden manually. When FSCS is
configured for Pairing and CBE lockout is required, only program points 65-96 on the first SCS module.
