What is the role of a Digital Alarm Communicator Receiver (D.A.C.R)?

1. To directly act on alarm signals

2. To accept and display signals sent via the public phone network

3. To convert analog signals to digital for processing

4. To send signals to fire stations

The correct answer is: To accept and display signals sent via the public phone network

The Digital Alarm Communicator Receiver (D.A.C.R) is specifically designed to accept and display signals transmitted over the public phone network. This device plays a crucial role in the fire alarm system by receiving alarm signals from remote locations, such as alarm panels or monitoring stations, and displaying those signals in a readable format. The use of the public phone network allows for reliable communication between the alarm system and monitoring stations, ensuring timely responses to emergencies. Understanding the function of a D.A.C.R. is vital for those in the fire alarm industry, as it highlights the importance of effective communication systems in monitoring fire alarms. The device does not directly act on alarm signals, convert analog signals, or send signals to fire stations; rather, it serves as an intermediary that facilitates communication of alarm events to the appropriate parties or systems. This clarity in its primary function underscores its critical role in alarm monitoring and response protocols.
