Terminals
The CRT-2 Terminal with keyboard features an 80-column, 25-line
display. Function keys allow all control panel commands to be executed
from the keyboard.
The CRT-2 requires 120-240 VAC, 50/60 Hz 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. An UPS is required for NFPA 72 Proprietary
Protected Premises Receiving Unit applications.
These are the CRT-2 Electrical Specifications;
• Voltage:
• Frequency:47-63 Hz
• Current:
Connection between the IFC-1010/2020 and the CRT-2 is provided
through an EIA-232 interface on the Serial Interface Board
(refer to Figure 79). A custom cable must be assembled for connection to
the CRT-2 EIA port. Additional CRTs are connected with installer
provided cables (AUX on first CRT-2 to EIA port on second CRT-2, etc.).
Refer to Figure 81 for wiring instructions.
The IFC-1010/2020 will support up to 25 terminals installed on the
EIA-232 circuit of the Serial Interface Board. Each CRT-2 is shipped from
the factory with a keyboard. This keyboard is used to program the control
panel and can only be used on one CRT-2 installed in the chain. The
keyboard must either be removed or locked after programming (except
NFPA 72 Proprietary Protected Premises and Central Station Receiving
Units, where the keyboard must remain installed and functional).
Note: The CRT-2 is factory programmed.
PAR
The PAR (Parallel), AUX, and EIA ports are located on the back of the CRT monitor.
