Honeywell NOTIFIER SCS Series User Manual

202 SCS Series Manual — P/N 15712:L 7/18/16
Appendix C: Special Applications
The features discussed in this appendix were introduced with SCS Manual 15712 Revision J. To use the new features on SCS V4.0, NFS2-
3030 and/or NCA-2 must be running software V21 or higher.
C.1 Mode A Operation
Mode A” is classic SCS operation as described in Section 3 of this manual. This mode is compatible with SCSV2.84 and higher.
C.2 Mode B Operation
When the panel is programmed as “Mode B”, and newest software is running, “Mode B” is also available. As described below, there are dif-
ferences in behavior when CBE lockout is programmed from when CBE lockout is not programmed.
C.2.1 Mode B without CBE Lockout: Independent Switch-Group Operation
 Definition
Classic SCS operation has dictated that manual mode (initiated by an event or by toggling any one switch) would affect all switch groups.
Independent switch-group operation describes a new mode of operation where a single switch group can enter manual mode without affect-
ing other switch groups. This is used in applications where smoke control zones are in physically separated parts of the building, but on the
same system.
 Programming
To get this form of operation:
• The NFS2-3030/NCA-2 must be programmed for Mode B.
• No points 65-96 should be programmed; i.e. no CBE lockout.
• Software versions must match those described above.
C.2.2 Mode B with CBE Lockout
 Definition
In Mode B operation, a manually controlled switch that is returned to the AUTO position will return to the lockout state (the state determined
by the first automated event).
When no automated event occurs, Mode B operation is like that described in Appendix C.2.1.

Programming
Mode B with CBE lockout requires point programming in position(s) 65-96.
When one of these points is programmed to monitor a panel zone containing smoke control points or a single smoke control device, activa-
tion of the zone or device will cause subsequent automatic events to be locked out. Smoke control can then only be overridden manually.
C.3 Multiple Smoke Control Station
 Definition
Multiple smoke control station operation is a feature that allows the configuration of a system with primary and secondary (redundant)
smoke control stations. Primary and secondary smoke control stations are capable of identical control and reporting.
Only one smoke control station can be active at any moment, as selected by manual input; visual indication of the active station is required.
Control is managed by a switch input and is hierarchical. The hierarchy of active control is established during system installation and pro-
gramming.

Programming
Multiple smoke control station operation requires:
• NCA-2 (V21 or higher).
• SCS-8L (V4.0 or higher).
