Comprehensive Guide to Alarm System Notifiers: Types and Applications

Alarm system notifiers are critical components in security and fire alarm systems (OHS). Their primary purposes are:

  1. State Visualization: Indicating the status of control panels and loops.
  2. Alerting in Emergencies: Drawing attention to unauthorized actions or hazardous situations.

For fire alarm systems, an additional function includes evacuation management, often supported by light panels with textual or graphical information, such as:

  • Text Indicators: "Exit," "Do Not Enter," or warnings like "Gas, Evacuate."
  • Graphical Cues: Arrows for evacuation directions or universally recognized safety symbols.

Security Alarm Notifiers

Categories of Security Notifiers:

  1. Sound Notifiers:

    • Purpose: Deter intruders by drawing attention.
    • Effectiveness: Limited when used indoors due to sound containment. Outdoor installations are more effective but require protection against tampering.
    • Examples: Ademco 702 or 719 models are known for their loudness and efficiency.

  2. Light Notifiers:

    • Functionality: Indicate system states (armed, disarmed, or alarm).
    • Features: Use energy-efficient LEDs with low power consumption and a long lifespan.
    • Benefits: Simple visual cues like steady, blinking, or colored light (e.g., red for alarm, green for safe) ensure easy interpretation.

Fire Alarm Notifiers

Mandatory Installations:

  1. Light Panels:

    • Applications: Guide evacuations with clear signs like "Exit" or "No Entry."
    • Regulatory Compliance: Adhere to fire safety regulations such as SP 3.13130.2009.

  2. Sound Notifiers:

    • Applications: Mandatory for alerting occupants about emergencies.
    • Types: Tonal alarms for small setups or voice announcements for larger facilities.
    • Key Considerations: Ensure adequate sound pressure levels across all occupied areas, factoring in background noise and distance.

Combined Light and Sound Notifiers

Combined notifiers integrate light and sound into a single unit, though their use is limited to specific applications like homes or small businesses. For large or complex systems, separate notifiers are often more effective due to tailored placement and optimization.

Popular Notifier Models and Brands

Key Installation Considerations

  1. Placement: Ensure visibility and audibility across the required coverage area.
  2. Tamper Resistance: Install notifiers in secure locations to prevent vandalism.
  3. Compliance: Adhere to regulatory standards for sound pressure levels and light intensity.
  4. Efficiency: Opt for energy-saving models like LED light notifiers to minimize operational costs.
