OOH941 Multi Criteria Smoke Detector

Model OOH941

Model OOH941 is an advanced, flexible multi multi-criteria fire detector that incorporates a redundant optical / thermal sensor. Additionally, Model OOH941 uses a distinctive forward / backward, light-scattering technology that provides state-of -the-art, unparalleled fire detection to the widest range of fire types.

Each Model OO H941 is programmed as a high 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 dual-optical thermal 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 modularfire-alarm control panels (FACPs)
  • Provides enhanced detection via forward-and-backward light-scattering technology
  • Complies with NFPA 76 (Telco standard) as `VEWFD’ high-sensitivity detector
  • UL Listed and FM Approved as a multi-criteria and `VEWFD’ fire detector
  • UL 268A Listed for direct air-duct use (4,000 FPM)
  • Supervisory temperature-monitoring feature
  • Remote sensitivity-measurement capability
