The CRT Terminal with keyboard features an 80 column, 25 line display. Function keys allow you to execute
FACP commands from the keyboard.

The CRT requires 120 VAC, 50/60Hz primary power. A secondary power source (battery backup) is not
provided; the use of a separate Uninterruptable Power Supply (UPS), UL listed for Fire Protective Signaling is
recommended.

Installation
Connection between the AM2020/AFP1010 and the CRT is provided through an EIA-232 interface on the
Serial Interface Board (SIB). Assemble a custom cable for connection to the EIA port on the CRT. Connect
additional CRTs with installer-provided cables (AUX on first CRT to EIA port on second CRT, and so on).
Multiple Terminals
The AM2020/AFP1010 supports up to 25 terminals installed on the EIA-232 circuit of the Serial Interface
Board. Each CRT is shipped from the factory with a keyboard, used for programming the FACP. The keyboard
can only be used on the first CRT installed in the chain. Only the first CRT is supervised on the EIA-232 circuit.
When finished programming, remove the keyboard.
The AUX and EIA ports are located
on the back of the CRT-1 Monitor.
The PAR (Parallel), AUX and EIA ports are
located on the back of the CRT-2 Monitor.
