Section 2: The Lcd2-80 & Terminal Mode - Honeywell Notifier LCD2-80 Instruction Manual

Section 2: The LCD2-80 & Terminal Mode
The LCD2-80 is set for Terminal Mode and 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, Drill and Reset.
NOTE:When LCD2-80s are used on the same EIA-485 circuit as
LCD-80s, the LCD2-80s must be at the furthest end of the circuit from
the panel.

Notes:
• EIA-485 circuits have a maximum of 6000 feet between units.
• Up to 32 LCD2-80s may be used on the EIA-485 circuit (consult control
panel's battery calculations).
• Between each LCD2-80 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 an EIA-485 circuit used in ACS Mode (annunciator interface).
• The EIA-485 terminal interface does not support the use of RPT-485
repeaters.
