4.2 Buttons
The LCD2-80 emulates
from one to 32
annunciators.
Acknowledge
When the Acknowledge
button is pressed on the
front panel, the LCD2-
80 sends an
acknowledge command
to the control panel, and
silences the local
sounder. In Terminal
Mode, additional key punches will step through what the host panel shows
for next events.
Silence
When the Silence button is pressed on the front panel, the LCD2-80 sends
a signal silence command to the control panel.
System Reset
When the System Reset button is pressed on the front panel, the LCD2-80
sends a reset command to the control panel.
Drill
When the Drill button on the front panel is pressed and held for 2 seconds,
the LCD2-80 sends a drill command to the control panel.
Display Step/Lamp Test
If the LCD display backlight has been turned off due to a trouble condition
in the system, momentarily pressing this switch will illuminate the display
for 60 seconds. If this switch is pressed and held in excess of 3 seconds,
the LCD2-80 will go into Lamp Test mode. During Lamp Test, all LEDs
will light, all segments of the display will turn on and the piezo will sound
for the duration the switch is pressed. Upon release of the switch, the
LCD2-80 software version number will briefly be displayed and then the
LCD2-80 will return to normal operation.
When the LCD2-80 is set for ACS mode, this button may be used to step
the display through multiple events. Events types are displayed in the
following order; alarms, supervisories, security alarms, non-fire events,
troubles, and outputs. This is a local function and does not send an
acknowledge command to the control panel. If a trouble condition has
turned off the backlighting, it also causes the backlit display to illuminate
for about one minute, and while held, turns on all LCD segments (lamp
test).
NOTE:
The Acknowledge, Silence and Reset and Drill buttons will serve
no function if the LCD2-80 has been set for Receive-Only operation
(DIP switch SW1-1 has been set ON)
