Section Two: Operating the LCD-80TM

Display Patterns

The LCD-80TM displays directly the information from the AFP-200 or AM2020/AFP1010 terminal interface without
alteration.
Note: The ALARMS PENDING, TROUBLES PENDING, Alarm Count and Trouble Count information will not be
displayed on the LCD-80TM.
If the LCD-80TM fails to receive communications from the panel for a period of over one minute, it will activate its local
sounder and display the following message:

Status Button

The LCD-80TM, when used with the AM2020/AFP1010 will keep a count of alarms in the system (number of alarm
messages, minus alarm clear messages, since the last ALL SYSTEMS NORMAL message). When this key is pressed
the alarm count is displayed in place of the time/date for 10 seconds.

Contrast Adjust

Repeatedly press this switch until the display's contrast is acceptable.

Lamp Test Button

If the backlight LCD display has been turned off due to a trouble condition in
the system, pressing this switch will illuminate the display for 60 seconds.
This switch also silences the local piezo. While it is held down, all segments
on the display will be turned on and the piezo will sound.

Global Acknowledge Button

When the Global Acknowledge switch is pressed on the front panel, the LCD-
80TM sends an Acknowledge command to the control panel, emulating a CRT
terminal.

Silence Button

When the SILENCE switch is pressed on the front panel, the LCD-80TM sends
a Signal Silence command to the control panel, emulating the CRT terminal.

Reset Button

When the System Reset switch is pressed on the front panel, the LCD-80TM
sends a Reset command to the control panel, emulating the CRT terminal.
Note: If Acknowledge, Silence, and Reset switches are enabled for system control, access security must be provided by
mounting the LCD-80TM in a locked Fire Alarm Cabinet, or Annunciator Backbox model ABF-1/1D or ABS-1T with AKS-
1 key switch option.
