button will cause the associated Alarm to activate when the sensor value falls below the value set for
that Alarm (Descending). Set Alarm’s 1, 2, and 3 to either ascending or descending.
b) When activated (blue), the ‘LAT’ button will cause the associated Alarm to be “Latching” and will not
allow that Alarm to reset until the cause is cleared or removed and the Alarm is reset with the reset
button. When de-activated (gray), the ‘N-L’ button will cause the associated Alarm to be reset when
the cause of the alarm is either cleared or removed. Set Alarm’s 1, 2, and 3 to either latching or non-
latching.
16) At the bottom of the screen are three boxes labeled “RELAY BANK SELECT”, “1”, “2”, and “3”. These
Bank Selection boxes will assign each sensor to a bank of alarms. Assigning a sensor to a Bank of alarms
allows the operator to create groups of sensor Alarms. When activated (Green) the sensor will be assigned
to the bank selected. I.E., selecting Bank 1 will assign that sensor to Bank 1; therefore, should an alarm
occur, it triggers the appropriate alarm in Bank 1 only.
17) Once all parameters for the sensor have been set appropriately, select “EXIT” to return to the Main Screen.
18) Proceed through all channels, setting each channel’s parameters to the desired values. When all channels
have been correctly set the unit should be ready for normal operation.
4.4 Remote Display Set-up
The remote display must be setup to match the main 880. The screens are duplicates of the Main 880;
therefore, the setup is accomplished in much the same manner as the main unit.
1) From the “Main Screen” (Figure 29), enter the “System Configuration Screen” by touching the “System
Configuration” box with the wand.
2) The display will prompt for a password to enter the 880 “System Configuration Screen”. The default
password is “1234”. Enter the password in the Pop-Up Screen and press enter to continue. This will
open the “System Configuration Screen” (Figure 30 – Analog, Figure 31 - Serial).
3) Use the wand to select the “FACILITY NAME” box. A keyboard will appear to allow input of the
facility name (Figure 32). The facility name can be any alphanumeric string of no more than 40
characters, and should be the same as the Facility Name entered in the Main 880. After the facility name
has been entered, use the ‘ENTER’ key to transfer the string to the “System Configuration Screen”.
4) Select the “TOTAL # OF CHANNELS” Box and input the number of channels that will be attached to the
unit. This number must match the number entered in the Main 880.
5) Select the “Exit” box to exit the “System Configuration Screen” and return to the “Main Screen”.
6) The “Channel Description”, “Gas Type”, and the range decimal point must be setup in the Remote
Display to match the information used to setup the Main 880. Sensor Range and Alarm information
should not be altered at the Remote Display. (This information is transferred over from the Main 880).
Use the wand to select a channel from the “Main Screen” and open that channel’s corresponding
“Channel Detail Screen” (Figure 34).
a) Select “Channel Description”. The keyboard will appear, allowing the input of the Channel Tag
Name, or a brief description of the sensor, up to 20 characters maximum. The “Channel Description”
here must match the “Channel Description” entered at the Main 880.
