GuardianSense™ Aspirating Smoke Detector (ASD)

Unrivaled Ultra-Early Fire Detection for Critical Environments

Protect your most valuable assets, ensure operational continuity, and safeguard lives with the GuardianSense™ Aspirating Smoke Detector (ASD). Engineered for unparalleled sensitivity and reliability, our ASD system detects invisible smoke particles at the earliest stages of combustion, long before traditional smoke detectors would react.

The GuardianSense™ ASD actively draws air from protected areas through a network of sampling pipes, analyzing it with advanced laser-based technology to identify even microscopic traces of smoke. This proactive approach provides crucial minutes of warning, enabling swift intervention to prevent catastrophic damage, minimize downtime, and ensure maximum evacuation time.

Key Features & Benefits:

1. Ultra-Early Warning Detection

• Feature: Actively samples air through a network of precisely engineered pipes, delivering it to a central detection unit.
• Benefit: Detects incipient fires at the earliest possible stage – often before any visible smoke, flame, or significant heat is present – giving you critical time to investigate and respond.

2. Superior Sensitivity & Accuracy

• Feature: Utilizes high-sensitivity laser particle counting technology.
• Benefit: Capable of detecting smoke concentrations far below the thresholds of conventional spot detectors, offering precise and reliable sensing even in the cleanest environments.

3. Multi-Stage Alarm Thresholds

• Feature: Configurable alarm levels (e.g., Alert, Pre-Alarm, Fire 1, Fire 2).
• Benefit: Provides graduated response capabilities, allowing for proactive investigation and staged mitigation without triggering full evacuation protocols unnecessarily, reducing false alarms and costly disruptions.

4. Environmental Adaptability & Robustness

• Feature: Designed to operate effectively across a wide range of challenging conditions, including extreme temperatures, high airflow, dusty environments, and hazardous areas.
• Benefit: Reliable performance where traditional detectors fail, ensuring consistent protection in diverse and demanding applications.

5. Discrete & Aesthetic Integration

• Feature: Sampling pipes can be easily concealed within ceilings, walls, or architectural features.
• Benefit: Maintains the aesthetic integrity of sensitive environments like museums, historical buildings, and luxury spaces while providing robust protection.

6. Simplified Maintenance & Accessibility

• Feature: The main detection unit is centrally located and easily accessible.
• Benefit: Enables safe and efficient servicing without needing to access potentially hazardous or difficult-to-reach areas (e.g., high ceilings, cleanrooms, cold storage), reducing maintenance costs and improving safety.

7. Intelligent Self-Diagnostics

• Feature: Continuous monitoring of air flow, filter status, and system integrity.
• Benefit: Provides real-time fault reporting, ensuring the system is always operating at peak performance and alerting you to any issues before they compromise detection capability.

8. Seamless Integration & Connectivity

• Feature: Multiple communication options including relay outputs, Modbus, BACnet, and Ethernet.
• Benefit: Easily integrates with existing Fire Alarm Control Panels (FACP), Building Management Systems (BMS), and security networks for comprehensive facility oversight.
