BFS20** is a **beam smoke detector** manufactured by **PHI (Protection Holdings Inc.

The BFS20 is a beam smoke detector manufactured by PHI (Protection Holdings Inc.).

Specifications:

  • Detection Principle: Infrared beam technology
  • Operating Voltage: 12–30V DC
  • Current Consumption: Typically 30mA (standby), 50mA (alarm)
  • Beam Length: Up to 100 meters (328 feet)
  • Operating Temperature Range: -10°C to +55°C (14°F to 131°F)
  • Humidity Range: 10% to 95% RH (non-condensing)
  • Enclosure Rating: IP30
  • Dimensions (Transmitter/Receiver): Approximately 150 x 100 x 60 mm
  • Weight: ~300g per unit
  • Compliance: Meets relevant fire detection standards (e.g., EN54-12)

Descriptions:

  • Designed for large, open spaces (e.g., warehouses, atriums, aircraft hangars).
  • Consists of a transmitter and receiver pair that detects smoke by measuring infrared beam obscuration.
  • Auto-compensation for gradual environmental changes (dust, dirt).
  • Relay outputs for fire and fault signals.

Features:

  • Wide coverage area (reduces the number of detectors needed).
  • High immunity to false alarms due to environmental factors.
  • LED indicators for power, fault, and alarm status.
  • Easy alignment with built-in alignment tool.
  • Compatible with conventional and addressable fire panels via relay contacts.

For exact installation and wiring details, refer to the official PHI BFS20 datasheet.
