C.5 Detector Maintenance Features
C.5.1 Overview
The NF2S-640 provides features to check the maintenance performance level of addressable,
intelligent detectors. Detector maintenance features include the following:
• View detector maintenance information for an individual detector
• Print a detector maintenance report for all detectors
C.5.2 How to Access Detector Maintenance Information
1. Access detector maintenance functions by pressing the
ENTER
key. The control panel displays
the Program Entry screen:
2. At the Program Entry screen, press the
M
key. The control panel displays the Detector
Maintenance Selection screen:
3. Press
1
or
2
to specify the SLC loop, then the detector’s three digit address, then press the enter
key; or to print a Detector Maintenance Report (Figure C.8 on page 104): Press
P
; then, press
the enter key.
C.5.3 View Detector Maintenance for a Detector
When you enter the detector SLC address the control panel displays the Detector Maintenance
Status screen as shown below:

Once you display information for a detector, you can use the
(Next Selection) and
(Previous Selection) keys to view information for the next or previous detector on the SLC.
Refer to “Interpreting a Detector Status Display or Maintenance Report” on page 104 for
descriptions of each item.
