Overview of Menus

4.0OVERVIEW OF MENUS

The Liqui-tect panel displays the Opening Screen at startup, as shown in Figure 14.

If any alarms are active, the Current Alarm screen appears. (Pressing any key on the LCD keypad will silence the audible alarm.)

If no alarms are present, the LCD screen will alternately display the Opening Screen and a screen showing NO ALARMS PRESENT.

If no alarms are present and the Enter (Return) key is pressed, the Main Menu appears and pre- sents two choices that lead to all functions within the panel:

View Status (see 5.0 - View Status Options for step-by-step instructions)

System and Control (see 6.0 - System and Control Options for detailed instructions)

4.1View Status Overview

The View Status features are available to all users—no password is required. This permits all person- nel to check on the status of any equipment or location being monitored. From this menu, any user may:

View cable status, the monitored cable length and the amount of current present (both zones)

View data stored in the Alarm History Log

View data stored in the Zone Trend Log

4.2System and Control Overview

The System and Control options require a password. Authorized users may:

Configure the Liqui-tect panel

Reset any latched alarms

Delete all records from the Alarm History Log

Delete all records from the Zone Trend Log
