Section 3 The LCD-80 & Terminal Mode
The LCD-80 set for Terminal Mode operates like a CRT terminal
without full keyboard capability, but with the advantages of 24 VDC
power, wall mount, and multiple terminal location with Acknowledge,
Signal Silence and Reset.
For AFP-200, AFP-300, AFP-400, AFC-600, AM2020/AFP1010,
NFS-640, and NCA, Terminal Mode is preferable to the ACS Mode
because it has full point-display capacity, and because it requires no
programming.
Note: LCD-80 terminal mode is not supported by System 500 or
System 5000.
Notes:
• EIA-485 circuits have a maximum of 6000 feet between units.
• Up to 32 LCD-80s may be used on the EIA-485 circuit (3.2 amps
regulated power max required - consult control panel’s battery
calculations. Note: When powered by the AFP-200, a maximum
of four LCD-80s may be connected to this circuit.
• Between each LCD-80 are four wires: A twisted-shielded pair for
data communications and an open pair for 24 VDC power. The
return circuit only requires two wires for data communication.
• The EIA-485 interface used in Terminal Mode should not be
confused with the EIA-485 circuit used in ACS Mode
(annunciator interface). With AM2020/AFP1010, the CCM-1
Convertor Module converts the EIA-232 Terminal Interface from
the SIB-2048 into the EIA-485 standard required by the LCD-80.
A separate EIA-485 circuit for powering ACS or LDM Series
annunciators can be taken off of the SIB-2048 Serial Interface
