Automatic fire detectors

Product catalog summary
Overview: The document provides detailed information on the Cerberus™ PRO and Cerberus™ FIT automatic fire detectors, specifically models OH720, OP720, HI720, and HI722, designed for use with the C-NET detector bus. These detectors are suitable for various applications, offering robust signal processing and automatic addressing during commissioning.
Properties and Features: The detectors are resistant to environmental influences such as dust, moisture, and extreme temperatures. They include features like shock resistance, sabotage protection, integrated line separators, and alarm indicators with 360° visibility. The detectors are eco-friendly, using reusable materials and easily separable electronic parts.
Types of Detectors:
  • OH720 Multi-sensor Fire Detector: Utilizes optical forward scattering and includes a heat sensor for increased immunity to false alarms. It offers two parameter sets for detection behavior: 'Robust' and 'Sensitive'.
  • OP720 Smoke Detector: Functions similarly to the OH720 but is specifically for smoke detection with 'Standard' and 'Sensitive' parameter sets.
  • HI720 Heat Detector: Offers static and differential heat detection with parameter sets 'A2S' and 'A2R', suitable for environments with fluctuating temperatures.
  • HI722 Heat Detector: Static only, with a parameter set 'A2S', designed for environments with short-term temperature fluctuations.
Intended Use: These detectors are intended for use on a C-NET detector line within FS720 or FC360 fire detection systems.
Technical Data: All models operate on DC 12-33 V, with varying quiescent currents and are compatible with FS720 and FC360 systems. They have a protection category of IP40, which can be increased to IP42 with a detector base seal.
Accessories: Various accessories are available, including detector bases, sounder bases, designation plates, and protective cages, each serving specific functions such as theft protection, enhanced IP protection, and mounting in wet environments.
Installation and Disposal: The document outlines installation guidelines, emphasizing the use of universal detector bases and proper disposal methods in accordance with European guidelines.
Approvals and Standards: The detectors comply with standards EN 54-7, EN 54-17, and EN 54-29, and have approvals from VdS, LPCB, FM, and DNV GL (marine).
Documentation and Support: Additional documentation is available for installation, technical manuals, and compatibility lists, issued by Siemens Switzerland Ltd.

Detector heating unit FDBH291 ● For operating point detectors in critical ambient conditions during icy conditions or when there is a danger of moisture condensation. Examples of application: Cold stores, attics, loading ramps, cheese cellars Optimum function is only guaranteed in conjunction with base attachment wet BA721. The point detector temperature increases by approximately 2 °C over the operating temperature and thus avoids moisture condensation on the detector. Mounted quickly: The detector heating unit clicks into place in the detector base. To protect the point detector from damage...
