The primary application for the LCD2-80 in ACS Mode is to display messages with text that is a subset of the panel message text, or cus-
tom messages programmed using VeriFire® Tools.
The power-limited EIA-485 interface provided by the control panels will support the installation of devices at up to 32 addresses.
Devices other than the LCD2-80 that can be installed at one of the 32 addresses include the ACS, LDM, and SCS modules.
The LCD2-80 can be mounted in ABF-1B, ABS-1TB, or ABS-1B backbox (not the ABS-1) or can mount on one slot of the CHS-4 chas-
sis. The ABF-1B may include an AKS-1B keyswitch and APJ-1B phone jack.
NOTE: For Canadian Applications, only the ABF-1DBC, ABF-1BC, ABF-2DBC, and ABS-2DC backboxes and chassis or door mount in
the CAB-4 Series Cabinets are approved for LCD2-80 installation.
