NFS2-3030 Operations Manual — P/N 52546:A 11/29/2005 35
Disabled Points Event Operation of the Control Panel
3. Investigate and correct the condition causing the Supervisory.
4. Press the SYSTEM RESET soft key to clear any supervisory condition caused by a device with
a latching type code: the supervisory will not automatically clear when the condition causing it
is cleared. Latching supervisory type codes are WATERFLOW S, LATCH SUPERV, and
SPRINKLR SYS.
The panel will send a system normal message to the History buffer, installed printer and
annunciators.
2.6.3 How to Interpret Type Codes
The Type Code that displays in the Supervisory message indicates the function of the point that
initiates the Supervisory. For example, a monitor module with a WATERFLOW S Type Code
means that the module monitors the state of a waterflow switch. If the Type ID code is unfamiliar,
refer to Appendix A, “Software Type ID Codes”, on page 63. This appendix is an alphabetical list
of Type ID codes and an explanation of each.
2.7 Disabled Points Event
The control panel indicates disabled points by displaying a screen for each disabled detector,
monitor module, and control/relay module. Disabled points do not cause an alarm or any
Control-by-event activity. If more than one point is disabled, the control panel automatically
displays each point in the sequence in which the point was disabled.
When one or more points are disabled, the control panel does the following:
• Holds all disabled output points in the off-state
• Flashes the
SYSTEM TROUBLE LED
•Lights the
POINT DISABLED LED
• Sends a Disabled Point message to the History buffer, installed printer and annunciators
NOTE: A supervisory condition caused by a device with a “tracking” type code automatically
clears and restores the panel to normal when the condition causing its activation disappears.
!
CAUTION:
When a zone is disabled, any input and output devices mapped to the zone are disabled if the zone
is the point’s primary zone. (The primary zone is the zone in the first position of the zone map.)
