🔍 Key Concepts

• basic electrical circuit theory (series vs. parallel circuits) • how fire alarm zones must behave when one detector activates • what happens to the rest of the system if one detector or circuit fails

💭 Think About

• Think about what should happen to the other detectors in the system if one detector in a zone goes into alarm or fails. Should they keep working normally, or stop working? • Consider how voltage and current behave differently in series circuits versus parallel circuits. Which type of circuit lets each device operate independently? • Imagine removing or disconnecting one detector from the circuit. In which wiring method would the rest of the system still function correctly?

✅ Before You Answer

• Review how series circuits behave when one component opens (is removed or fails). • Review how parallel circuits behave when one branch opens, and what that means for power to the other branches. • Confirm which arrangement is normally used so that a single detector failure does not disable the entire zone.
