Description
Types of Smoke Alarms
- Ionization Smoke Alarm:
- Advantages: More effective against fast-flaming fires (e.g., paper fires, kitchen fires).
- Working Principle: Detects smoke particles by ionizing air molecules and measuring changes in electrical current.
- Photoelectric Smoke Alarm:
- Advantages: More effective against slow-smoldering fires (e.g., fires from burning cigarettes in couches or bedding).
- Working Principle: Uses a light source and a sensor to detect smoke particles that scatter light.
- Combo Units:
- Features: Combine ionization and photoelectric technologies.
- Advantages: Provide early warning for both fast-flaming and slow-smoldering fires.
Power Sources
- Battery-operated: Easy to install, but batteries need regular replacement.
- Household current (hard-wired): More reliable, but installation requires a qualified electrician.
- Plug-in: Convenient, but must have restraining devices to prevent accidental disconnection.
Where to Install Smoke Alarms
- Locations:
- Install on every level of your home, including the basement.
- Install in every sleeping area.
- Ensure all family members can hear the alarm.
- Mounting:
- Wall-mounted: Place the top of the alarm 4-12 inches (10-30 centimeters) from the ceiling.
- Ceiling-mounted: Position at least 4 inches (10 centimeters) away from the nearest wall.
- Avoid These Areas:
- Do not install near windows, doors, or forced-air registers (drafts can interfere with the alarm's operation).
- Keep at least 10 feet away from stoves and steamy showers to avoid false alarms.
How to Install Smoke Alarms
- Follow Manufacturer's Instructions: Use a drill and screwdriver as specified.
- Plug-in Alarms: Ensure they have restraining devices to prevent accidental disconnection.
- Hard-wired Alarms: Must be installed by a qualified electrician.
- Important Note: Never connect a smoke alarm to a circuit that can be turned off from a wall switch.
Additional Tips
- Regular Maintenance: Test smoke alarms monthly and replace batteries annually.
- Expiration: Replace smoke alarms every 10 years or as recommended by the manufacturer.
- Multiple Alarms: For larger homes, consider interconnected smoke alarms so that when one alarm sounds, all alarms go off
Key Features
- Power Supply:
- AC Power: Operates on 240V AC, suitable for standard household or commercial electrical systems.
- Battery Backup: Equipped with a 9V DC battery backup to ensure continuous operation during power outages.
- Detection Technology:
- Photoelectric Chamber: Utilizes a photoelectric sensor for early detection of smoke particles from all directions. This technology is particularly effective for detecting slow-smoldering fires, which produce large smoke particles.
- Alarm Signal:
- Loud Alarm: Produces an alarm signal louder than 85 decibels (A-weighted) at a distance of 3 meters. This loud alarm ensures that occupants are alerted promptly in case of a fire.
- Mounting Options:
- Ceiling or Wall Mounting: Suitable for installation on either ceilings or walls, providing flexibility based on the layout of the space.
- Surface Mount Base Plate: Features a surface mount base plate with large cable terminals for easy installation and connection.
- Interconnectivity:
- Single or Interconnected Operation: Can operate as a standalone unit or be interconnected with up to 24 other smoke alarms. This feature is particularly useful in larger homes or commercial buildings to ensure coordinated alarm activation.
- LED Indicators:
- Red LED: Indicates alarm status when smoke is detected.
- Green LED: Shows AC mains power status, confirming that the alarm is connected to the electrical supply.
- Low Battery Signal: Alerts users when the backup battery needs replacement, ensuring the alarm remains functional during power outages.
- Protection Features:
- Insect Screen: Equipped with an insect screen to protect the sensing chamber from interference by insects or dust, ensuring accurate detection.
- Physical Specifications:
- Net Weight: Approximately 214 grams.
- Dimensions: 120 mm diameter and 43 mm height (Ф120*43mm).
Applications
- Residential Use: Ideal for homes, apartments, and residential buildings.
- Commercial Use: Suitable for offices, hotels, and other commercial spaces.
- Multi-level Buildings: The interconnectivity feature makes it perfect for large or multi-level structures where coordinated alarm activation is crucial.
Installation and Maintenance
- Installation: Follow the manufacturer's instructions for proper installation. Ensure the alarm is mounted high on walls or ceilings, away from drafts and sources of false alarms (e.g., near stoves or showers).
- Testing: Regularly test the alarm to ensure it is functioning correctly. Replace batteries annually or as indicated by the low battery signal.
- Replacement: Replace the entire unit every 10 years or as recommended by the manufacturer to ensure optimal performance.
