Which device is used to produce hard copies of alarms and data trends in a building automation system?

Explanation:
In a building automation system, producing a physical record of events and trends is handled by a device designed to print data on paper. An alarm printer is built to take alarm events and data trends from the system and output hard copies with timestamps and relevant details, which is essential for incident records, audits, and shift reports. The other options don’t specialize in printing: a front end is mainly for user interaction and data processing, not for generating printouts; a dumb terminal displays information but isn’t a printer by itself; a keypad display is a local input/output device with limited display capability, not intended for printing long logs or trends.
