Safety is a deep-rooted, fundamental need. That’s why solutions that reliably protect people, assets, and processes against fire, smoke, and carbon monoxide play such a crucial role. Desigo Fire Safety comprises everything needed for comprehensive fire protection:

• Fire detectors with excellent reliability prevent false alarms and meet the requirements of the fire safety and carbon monoxide codes NFPA 72 and NFPA 720.
• Control panels, fire terminals, remote terminals, and displays provide full system view and are easy to operate, even in the case of an event.
• Complete range of peripherals, ranging from notification devices to manual alarm stations.

Safe, precise, and reliable
Reliable detection, fast notification, quick response – Desigo Fire Safety sets the standard in all three areas, including:

• Redundant sensors that increase the reliability of the fire detectors.
• Forward and backward light scattering technology that ensures enhanced sensitivity to actual fires and practically eliminates false alarms.
• All detectors with ASAtechnology™ come with a No False Alarm Guarantee.

A special carbon monoxide (CO) detector detects CO, whether generated by or independent from fire. Fast, fault-tolerant communication between FDnet devices and the control panels increases system reliability. The control panels allow simple, intuitive operation, plain text displays, and clear instructions, which allow security personnel to focus on the event.

Meeting every need from “standard” to “special”
Desigo Fire Safety is a homogeneous family of fire detectors and control panels whose models are all compatible. From standard to special situations, it’s easy to realize the benefits of this comprehensive system:

• Reliable detection confirmed by the S-LINE detector’s No False Alarm Guarantee

Siemens owns one of the largest fire test laboratories in the world. We conduct live fire behavior tests in eight test labs. Our database contains more than 5,000 tests. We factor all of this information into the development of our Desigo fire detectors.

Intelligent technology for enhanced detection

One family to cover virtually any application
Desigo fire detectors answer virtually any application need, from standard to sophis-ticated and from clean to dirty. The C-LINE detectors are an economical, reliable solu-tion for standard applications. The S-LINE detectors are the best choice for more demanding applications with deceptive phenomena, when extremely fast response time and the highest level of prevention of false alarms is needed. Detectors from both lines can be used together in a single network. In short, Desigo allows you to manage diverse detection requirements with one detector family and one system.

Unique sensor technology
In multiple environmental conditions, Desigo detectors reliably detect any sign of fire as early as possible. Their unique sensor system utilizes state- of-the-art forward and backward light scattering technology. This technology provides advanced optical analysis of light and dark smoke particles. As a result, it improves the detection capabilities of the detectors and makes them virtually immune to false alarms. Desigo detectors comply with NFPA 76 (Telecommunication Standard) and are classified as Very Early Warning Fire Detectors (VEWFD). This means that they are extremely sensitive and provide very early detection.

A smart choice for the environment
The detectors are RoHS compliant, meeting the standards regarding the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment. S-LINE detectors also provide enhanced detection capability equivalent to ioniza-tion detectors due to their forward and backward light scattering technology. This makes them a great “green” solution.

Redundant sensors increase reliability
S-LINE detectors have two thermal and two optical sensors. This redundancy heightens their immunity to deceptive phenomena and increases their detection capability and reliability. Should one sensor fail, the detec- tors will still provide fail-safe operation.

Highlights

• One detector portfolio to cover most application areas, from clean to dirty

• Reliable detection that eliminates false alarms due to unique forward and backward light scattering technology
  Compliant with NFPA 76 (Telecommunication Standard) and classified as a VEWFD

• RoHS compliant, with detection capability equivalent to ionization detectors due to forward and backward light scattering technology

• Increased reliability and fail-safe operation thanks to redundant sensors

Legend

1. Two IR light sources
2. The rays of the two IR light sources are scattered by smoke particles in the sampling chamber and strike the light receiver.
3. IR receiver: the special position of the two IR light sources helps to distinguish between light and dark smoke particles due to forward and backward light dispersion.
4. The patented labyrinth absorbs light emitted by the light sources, thus preventing random reflection. It also captures small fibers and dust particles so that they do not enter the sampling chamber.
5. Redundant temperature sensors (two) measure the temperature.
6. The monitored CO sensor measures the CO concentration.

S-LINE – setting new standards with ASAtechnologyTM

U nsurpassed reliability
Preventing downtime and costs caused by false alarms are central considerations for any company. ASAtechnology™
(Advanced Signal Analysis) offers extreme detection reliability with the immunity to deceptive phenomena. Therefore, we offer a No False Alarm Guarantee with this detector.

Sophisticated applications require exceptional technology
S-LINE detectors feature our unique ASAtechnology™. This makes them highly reliable in preventing false alarms caused by deceptive on-site phenomena, such as machine exhaust gases, dust, or steam. This provides excellent protection and extremely reliable detection in critical applications, ranging from very clean environments like data centers and tele-communications centers to dirty industrial applications like warehouse facilities.

Highest life safety
The multi-criteria fire/CO detector FDOOTC441 combines ASAtechnology™ with carbon monoxide (CO) detection for maximum life safety. It responds very quickly and reliably to fire or the presence of CO. With two optical and two thermal sensors and one additional electrochemical CO sensor, FDOOTC441 analyzes fire criteria: smoke, heat, and CO. The addi-tional CO sensor ensures earliest detection of CO-generating fires and detects CO independently from fire. FDOOTC441 complies with the requirements of the fire safety and carbon monoxide codes and standards UL 2075 and NFPA 720.

Meeting changing needs
S-LINE fire detectors offer more than 20 application-specific detection profiles that let you adjust the detectors to the expected environmental condition. Should the conditions change, you simply modify the detector by adjusting the detection profile. This provides for reliable and early fire detection even under changing environmental conditions.

Highlights

• Unique detection reliability and No False Alarm Guarantee provided by ASAtechnologyTM
• Fast, reliable detection of smoke, heat, and carbon monoxide
• Earliest detection of CO- generating fumes, also independently from fire, with the CO detector
• Enhanced life safety provided by selectable fire detection profiles
• Adjustable detection profiles guarantee quick, cost-efficient adaptation to environmental conditions

C-LINE – for standard applications

Reliable in operation
Backed by many years of field experience and proven under numerous operating conditions, the Desigo C-LINE fire detectors provide comprehensive safety. This makes C-LINE detectors a great choice in standard environmental conditions where only occasional deceptive pheno-mena occur, in typical commercial applications such as:

• Retail stores
• Restaurants
• Offices

Modern, cost-effective technology for investment protection
The addressable technology in the line network FDnet (Field Device network) permits fast, fault-tolerant communication between fire detectors and the control panel. All existing wiring can continue to be used. The C-LINE detectors’ integrated algorithms can easily be adjusted if the room or building usage changes in the future. This makes C-LINE detectors a cost- efficient solution and long-term investment.

All-around safety
The installation of the detectors on the FDnet circuit increases safety. In the event of malfunction, alarms are simply redirected the other way to the control panel.

Highlights

• State-of-the-art detection algorithms
• Continued use of existing wiring
• Reliable and efficient fire detection
• Protection of your investment thanks to the system’s flexibility and the ability to respond to changing needs
