Stratos-HSSD 2

Stratos-HSSD 2 embodies innovative features which depart from accepted techniques for detectors which operate at very high sensitivity. Perhaps the most important feature of the system is the adoption of a patented ‘artificial intelligence’ known as ClassiFire-3D. This controls all aspects of the system operation. ClassiFire-3D ensures that Stratos-HSSD 2 operates at maximum SAFE sensitivity to give warning of problems earlier than previously considered possible.

ClassiFire-3D is the most comprehensive intelligence found in a smoke detection system to date. Not only does it determine the maximum reliable sensitivity for the environment, but it also controls the dust separator monitoring for maximum efficiency.

The detection principle used in Stratos-HSSD 2 is known as ‘forward light scattering’ where the laser beam is diffracted by a small angle by smoke particles. This principle not only offers high sensitivity, but sensitivity to a known range of particle sizes.

A patented feature of the system is that compensation is made for any contamination, ensuring a long and trouble free life.

The Stratos range of detectors are the only high sensitivity systems which are routinely applied to the protection of very dirty and dusty environments. This is achieved by using Laser Dust Discrimination (LDD) with a patented dust management and separator system. These features have greatly extended separator life service intervals. At the other extreme, Stratos-HSSD 2 is capable of providing the very highest levels of sensitivity in environments such as computer and clean rooms. In these applications it is able to sense the very smallest amounts of smoke.

By using the latest semiconductor laser, electronic components and manufacturing techniques enable the Stratos-HSSD 2 system to be supplied and installed with a significantly lower whole-life cost then alternative high sensitivity systems.

Stratos-HSSD 2 provides four alarm level outputs and a fault output to the fire alarm panel. When an addressable panel is used the Addressable Protocol Interface Card (APIC) is used to communicate using the addressable protocol. Using the APIC means that the alarm and fault relays can be used for other purposes.

Up to 127 Stratos-HSSD 2 and Stratos-Micra detectors may be networked together using RS485 cabling and the Stratos-HSSD 2 has a built-in RS485 repeater that allows up to 1.2km between each detector. For improved fault-tolerance the RS485 may be looped using a Command Module which will give indication of the location of any cable breaks or shorts and maintain communication. When using a Command Module a single Addressable Protocol Interface Card (APIC) can signal the individual status of each detector back to a fire panel, greatly reducing interfacing cost and complexity.

Stratos-HSSD 2 is supplied with comprehensive diagnostic facilities as standard, giving the capability of fault finding down to the individual component level. ClassiFire-3D may be viewed working in real time by attaching a PC running the remote software. You can also view a detailed chart recorder of historical smoke levels showing date, time and alarm thresholds.

A reduced cost minimum display version of the Stratos-HSSD 2 is available. It has no on-board programmer and has only Fire 1, Fault and Ok indicators. A PC is required to install and commission the minimum display version.

Stratos-Micra25/100

Stratos-Micra 25 is intended to provide LOCALISED incipient fire detection only. This means that it is suitable for the substantial range of applications typified by; small non-compartmentalised rooms, warehouse racking, or pieces of electronic or electromechanical equipment where it is desirable to achieve individual incipient fire reporting. In compartmentalised rooms, each compartment would normally use individual Stratos-Micra 25 detectors.

This product employs a very low-power aspirator and the aspirating capability of the Stratos-Micra 25 detector is limited accordingly. Stratos-Micra 25 is NOT intended to protect large areas, or to sample from areas where there may be any difference in airflow rates or pressure differentials. Application of Stratos-Micra 25 in these circumstances is not recommended. If detection in environments conforming to these descriptions is required, alternative versions of Stratos products should be used.

We recommed a maximum sampling pipe length of 25 metres to be used on the Stratos-Micra 25. Maximum single length of sampling pipe to be used on the Stratos-Micra 100 detector is 100 metres (or 2 x 50 meter lengths) in still air with 25 sampling holes (or Capillary Remote Sampling Points). This will provide a transport time from the end of the sampling pipe within 120 seconds. If the protected area has airflow present, the maximum permitted sampling pipe length will be reduced.

Stratos-Micra 100 has two pipe inlets and supports a maximum of 100 metres of sampling pipe.

Stratos-Micra is available with an optional ‘Piped Exhaust’ type Docking Station. This is primarily intended to allow the Stratos-Micra detector to sample from areas which may be at different air pressure to the detector location. Typical uses are for air-duct sampling and allowing the installation of the detector in under-floor or ceiling voids or when sampling from pieces of computer related equipment.

Stratos-Micra provides four alarm level outputs and a fault output to the fire alarm panel. Relays for Fire 1 and Fault are fitted as standard. When an addressable panel is used the Addressable Protocol Interface Card (APIC) is used to communicate using the addressable protocol. Using the APIC means that the alarm and fault relays can be used for other purposes.

Stratos-Micra is supplied with comprehensive diagnostic facilities as standard. By simply plugging a PC into the serial port display diagnostic menus will give the capability of fault finding down to individual component level. ClassiFire-3D may be viewed working in real time. It is also possible to view a detailed chart recorder of historical smoke levels showing date, time and alarm thresholds.

Stratos-EX

Stratos-Ex™ is a highly sophisticated ‘next generation‘ of High Sensitivity Aspirating Smoke Detection product that has been designed to ensure that installation and commissioning is as simple as possible, whilst optimising performance.

Stratos-Ex incorporates a patented system of ‘Perceptive Artificial Intelligence‘ known as ClassiFire®, which allows the detector to initially configure and then to maintain itself at optimum sensitivity. ClassiFire also monitors the detector chamber and dust separator for contamination, continually adjusting the appropriate operating parameters to counteract the negative effects of such contamination.

The Stratos® range of detectors are unique in being able to provide a consistent level of protection in a very wide range of environments by continuously making minor adjustments to sensitivity. Detectors from this range have proven their worth many times by detecting ‘difficult-to-detect‘ slow-growth electrical overload incipient fires in ‘difficult‘ environments.
