Sensor Status Mode
Pressing and releasing the MODE button for more than 2
seconds but less than 5 seconds places the display into Sensor
Status Mode. During this time interval, the display shows STS.
Function
The user can scroll through status information for each sensor
in the system, including the current %LFL and any active Fault
states. Alarm states are indicated by the %LFL level exceeding
the alarm threshold (typically 15%).
Display
1. The user scrolls through the information by subsequent
button presses after entering the Sensor Status Mode.
2. The display shows the sensor number, %LFL, and active
fault (if any).
3. The display will scroll through all eight sensors (1-8) and
show LOC for any sensors not communicating or not
installed.
4. In the case of a system with four sensors, where three
sensors are operating normally and sensor 2 has an
internal fault, the display responds as shown in Table 11 on
page 11.
