Which term describes the printer used with a BAS to produce hard copies of alarms, preventive maintenance messages, and data trends?

• A. Front end
• B. Alarm display
• C. Data printer
• D. Alarm printer

Answer: (D)

In a BAS, a device that produces hard copies of alarms, preventive maintenance messages, and data trends is specifically designed for documenting events as they happen. This is an alarm printer. It’s built to print out alert conditions, maintenance notices, and trend data so technicians have tangible records for audits, troubleshooting, and maintenance planning.

The other terms don’t fit as closely: a front end is the user interface or control processor, not a printer. an alarm display shows alarms on a screen rather than producing a physical printout. A data printer might handle general data prints but isn’t oriented to capturing alarms and maintenance messages, which is why the alarm printer is the best description for this purpose.
