CO Alarm Event Operation of the Control Panel
Figure 2.8 CO Alarm Message Display Example
2.7.2 How to Respond to a CO Alarm
If the control panel indicates a fire alarm, the operator can do the following:
• To silence the panel sounder:
Press the ACKNOWLEDGE soft key. The local sounder will silence and the
OTHER LED will
change from flashing to steady. The control panel will send an acknowledge message to the
panel display, history buffer, installed printers and annunciators.
• To silence any activated outputs that are programmed as silenceable:
Press the SIGNAL SILENCE soft key.
SIGNALS SILENCED LED lights steady. The control
panel sends a Signal Silenced message to the History buffer, installed printers and
annunciators.
5. Check the Alarm message for its location and type. Press the MORE INFORMATION soft key
to display the MORE INFORMATION screen and view additional information on the device and
possibly preprogrammed text for recommended action. (Refer to Figure 1.8 on page 19 for an
example of the this screen and an explanation of its fields.)
6. Correct the condition causing the CO alarm.
7. When the CO alarm condition is corrected, press the SYSTEM RESET soft key to return the
control panel to normal operation (indicated by the “System Normal” message). The control
panel sends a “System Normal” message to the panel display, history buffer and installed
printer.
The soft key PROGRAM/ALTER STATUS is also displayed on this screen. A password is required
to enter these menus, which are described in the NFS2-3030 Programming Manual.
2.7.3 Interpreting Type ID Codes
The Type ID code that displays in the CO alarm message is related to the type and function of the
point that initiates the CO alarm. For example, a monitor module with a
CO MONITOR Type ID code
means that the monitor module monitors a conventional CO detector. If the Type ID code is unfa-
miliar, refer to Appendix A, “Software Type ID Codes”, on page 78. This appendix is an alphabeti-
cal list of Type ID codes with an explanation of each.
