OOHC941 ASA Multi-Criteria Fire | CO Detector

Model OOHC941

Model OOHC941 is an advanced, multi-criteria fire | CO detector that incorporates a redundant optical / thermal sensor. Additionally, Model OOHC941 uses a distinctive forward / backward, light-scattering technology that provides high-tech, unparalleled fire detection to the widest range of fire types.

Each Model OOHC941 is programmed as a high-sensitivity detector, thus meeting the requirements of NFPA 76 Standard (for the Fire Protection of Telecommunications Facilities) as a Very Early Warning Fire Detector (VEWFD).

  • Advanced multi-criteria fire detector that has optical thermal and CO sensors
  • Differentiates between deceptive phenomena and an actual fire (nuisance-alarm avoidance)
  • Compatible with Siemens Model `H’-series devices on the same loop (with Cerberus PRO modular | FireFinder XLS/V | FC/FV9–series fire-alarm control panels [FACPs])
  • Provides enhanced detection via forward-and-backward light-scattering technology
  • Supervisory feature for temperature and CO-concentration-threshold monitoring
  • Complies with NFPA 76 (Telco standard) as `VEWFD’ high-sensitivity detector
  • UL Listed and FM Approved as a multi-criteria and `VEWFD’ fire detector
  • Low-temperature warning for sprinkler systems, per NFPA 25
  • UL 268A Listed for direct air-duct use (4,000 FPM)
  • UL 2075 and NFPA 72 requirements for sensitivity self-monitoring
  • Remote sensitivity-measurement capability
  • Tri-color detector-status light-emitting diode (LED) with 360°view
  • Polarity insensitive via SureWire™
  • Responds to both flaming and smoldering-fire signatures
  • Supervisory temperature-monitoring feature
  • Automatic environment compensation
  • Meets UL, NFPA 72 requirements for sensitivity self-monitoring
  • Compatible with:
    -Model DB-11—series mounting bases
    -Model DPU (device programmer / loop tester)
  • Restriction of Hazardous Substances (RoHS compliant)
  • UL 268 Listed, ULC Listed; FM (#3230,#3210), CSFM (#7272-0067:0258) Approved
