Johnson Controls launches 700 Series microprocessor-based conventional fire detectors

New group of standard detectors have got built-in microprocessors that keep track of and react to smoke density, set temp, and rate-of-rise of temperatures

  • Drift compensation function extends service living and reduces maintenance requirements
  • Detectors were created and stated in Europe and adhere to Sobre54 and LPCB specifications

Johnson Regulates, the global head for smart, healthful and sustainable structures – and architect of OpenBlue linked solutions and providers – announces the brand new 700 Series Typical Fire Detectors, the company’s first microprocessor-based regular fire detectors that specifically monitor and react to building fire circumstances. The inclusion of a microprocessor over the entire variety means these typical detectors offer superior algorithms, resulting in exactly the same detection efficiency and fake alarm rejection because the company’s newest non-Fastlogic, Gen6 detectors.

The five fire detectors in the collection (701P, 701PH, 701H, 702H, and 703H) each react to special parameters including smoke cigarettes density, fixed heat range, and rate of increase of temperature, after that notify fire recognition panels to supply an alarm reaction for the impacted zones. The 700 Collection Detectors provide a complete fire recognition solution – including drift payment – perfect for small commercial structures such as shops and company campuses.

Smoke recognition and drift settlement

The 701P smoke detector functions by sensing the optical scatter from smoke cigarettes contaminants generated in a fire. That is suitable for applications such as for example electrical services areas where cable overheating may occur.

The 701PH heat and smoke detector operates as a typical optical detector under normal ambient conditions. However, whenever a rapid rise in temperature is detected, the sensitivity of the optical detector increases to greatly help better identify smoke particles. The 701PH may be the first conventional detector from Johnson Controls that is approved to EN54-29, a non-harmonized standard for multi-sensor detectors.

The 701P and 701PH detectors both offer drift compensation (or threshold compensation), a smart feature that monitors the known degree of dust and debris within the optical detector, adjusts the sensor to pay for the obstruction then. This total results in improved reliability as time passes, extended life of the detectors, and less maintenance needs.

Heat-based fire detection

The 701H can be an A1R heat detector that uses both rate-of-rise and 60°C static temperature sensing, where in fact the fixed element offers a backstop for fires where the temperature accumulates gradually.

The 702H can be an A1S temperature detector with a static reaction heat of 60°C (Sobre54-5). Since it just responds at these particular temperatures, this detector will be areas ideal for restaurant dining, retail facilities, and resort rooms.

The 703H heat detector includes a static response temp of 90°C (Sobre54-5), which is most effective in areas where higher temperatures are normal such as for example boiler kitchens and rooms.

“The product series supplies a full-building fire recognition solution that will require only one visit to the ceiling to perform set up,” mentioned Paul Grainger, product supervisor, Johnson Settings. “Along with reliability and accuracy, this type of fire detectors provides been made to reduce program and installation maintenance charges for our customers, through fast, easy set up and a protracted detector service lifetime.”

The Johnson Controls 700 Collection Conventional Fire Detectors are usually EN Listed, with UL and ANZ Listed versions quickly coming.
