🔍 Key Concepts

• Auto alarm systems and how they respond to electrical problems • Effects of intermittent electrical faults (like loose contacts or weak tubes) on alarm circuits • How line voltage fluctuations can influence sensitive electronic selectors and relays

💭 Think About

• For each option, ask: Could this realistically cause an on‑again, off‑again (intermittent) activation of the alarm bells? • Think about which components directly affect whether the alarm circuit opens and closes repeatedly. • Consider whether the problem described is very specific (one component) or could be the result of several different kinds of electrical issues.

✅ Before You Answer

• For each choice, decide if it can cause intermittent operation, not continuous failure. • Ask if the device listed directly affects the alarm circuit continuity or its power supply. • Before choosing, verify whether more than one listed condition could independently produce the same intermittent symptom.
