Real-World Example: Troubleshooting in Action
Scenario:
Jane, a homeowner in Perth, noticed her hard-wired smoke detector was beeping intermittently late at night. After confirming there was no fire or smoke, she tried the following steps:
Checked the backup battery: Jane replaced the battery with a fresh one.
Pressed the reset button: Holding it down for 20 seconds silenced the alarm temporarily.
Inspected the device: She cleaned it with a vacuum attachment to remove accumulated dust.
Despite her efforts, the beeping resumed after an hour. Jane called Web X Electrical, and a licensed electrician identified a wiring fault during their inspection. The faulty connection was repaired, and the issue was resolved.

Ionization vs. Photoelectric Smoke Detectors
| Criteria | Ionization Detector | Photoelectric Detector |
|---|---|---|
| Pros | - Quick response to fast-flaming fires. - Affordable and widely available. - Lightweight and compact. | - Quick detection of smoldering fires (e.g., from furniture). - Fewer false alarms from cooking smoke. - Better performance in homes with interconnected alarms. |
| Cons | - Prone to false alarms near kitchens or bathrooms. - Less effective for smoldering fires. - May require frequent cleaning to avoid dust buildup. | - Generally more expensive than ionization models. - Slower to detect fast-flaming fires. - Larger in size due to more complex components. |
| Ideal Use Case | Near bedrooms, hallways, and areas away from cooking smoke. | Near kitchens, living rooms, and areas prone to slow-smoldering fires. |
| Price Range | $180 - $200 | $200 - $220 |
