Smoke detectors are characterized by their sensing technology (ionization for fast flames, photoelectric for smoldering fires, or dual-sensor), notification methods (loud audible alarms, flashing LEDs, voice alerts), power sources (battery, hardwired with backup), and connectivity (standalone, interconnected wirelessly/hardwired). Key features include test buttons, indicator lights, long life (around 10 years), and modern options like CO detection and smart home integration.
Key Characteristics
Detection Technology:
Ionization: Detects fast-flaming fires by disrupting an electrical current with smoke particles.
Photoelectric: Senses smoldering fires by scattering a light beam onto a sensor.
Dual-Sensor: Combines both ionization and photoelectric sensors for broader detection.
Aspirating (ASD): Actively samples air for very early detection in sensitive areas.
Alarm & Notification:
Audible: Loud, distinct sound (different from other signals per NFPA standards).
Visual: Flashing LEDs.
Voice Alerts: Announces danger and location (e.g., "Fire in the kitchen").
Power & Interconnection:
Battery-Powered: Uses replaceable batteries, chirps when low.
Hardwired: Connects to home's electrical system with battery backup.
Interconnected: All alarms sound when one detects smoke (wireless or wired).
Physical Features:
Housing: Plastic (ABS, polycarbonate), circular/rectangular, with vents.
Buttons: Test/hush buttons.
Indicator Lights: LEDs for power/alarm status.
Modern Features:
Carbon Monoxide (CO) Detection: Combines smoke and CO sensing.
Smart Home Integration: Connects to Wi-Fi for alerts on smartphones.
Lifespan: Typically needs replacement every 10 years.
