A signal from each _______ system shall be connected to the master alarm panels to indicate that a problem is present with the source equipment.

A signal from each _______ system shall be connected to the master alarm panels to indicate that a problem is present with the source equipment.

• A. anesthetizing
• B. pressure switch
• C. area alarm
• D. local alarm

Answer: (D)

The idea being tested is centralized fault signaling for source equipment. Each piece of source equipment has a local alarm that detects problems and signals the master alarm panel. This setup lets the master panel show a problem and identify which specific piece of equipment is affected, enabling quick response and maintenance. The local alarm is the correct concept because it is the alarm installed at or near the individual device, designed to report its status to the central master panel. A pressure switch is a sensing device, not the signaling path to the master panel. An area alarm monitors a room or zone rather than tying directly to each source equipment’s status. An anesthetizing system refers to the type of gas-delivery setup, not the signaling mechanism to the master panel.
