MZX systems include the most extensive range of products which are suitable for and approved for use in all classes of hazardous areas. The range extends from intrinsically safe detectors for use on conventional systems to flameproof and intrinsically safe flame detectors for use in the most demanding environments, both on and off shore. A complete range of barriers, housings, call points, ancillary modules and sounders is provided to enable a complete system to be supplied. System 620 conventional and system 800 addressable solutions include detailed design guides ensuring the system designer has all the tools to implement a safe and effective solution. ATEX and IECEx approvals are in most cases for both dust and gas hazards. In addition to individual component approvals both conventional and addressable systems have systems certification.

Flame Detectors

MZX Infra-Red Flame detection offers unrivalled performance where hydrocarbon based fires exists. IR detection is less susceptible to radiation inhibitors than is UV, being able to detect through oil mist, smoke and vapour, all of which can be commonly associated with fires involving fuels. They are also less prone to false alarms from background radiation sources.

Infra red (IR) sensors are tuned to a bandwidth typical of the radiation emitted from carbon dioxide which is present in hydrocarbon fires. Single channel detectors are set to a fixed frequency and then rely on flame flicker, whereas triple channel detectors can monitor frequencies above and below the fire threshold filtering background radiation from non-fire sources. Array based IR detectors use 256 sensors making them sensitive yet extremely stable. The array can be configured to ignore hot spots such as exhausts, flues and flame stacks. The detector in addition to all other approvals is IEC61508, (SIL2) approved.

Some models can also incorporate a CCTV camera within the detector housing, providing real time images of the incident. All of the above detector types are available within the MZX range covering all categories of risks.

Intrinsically Safe Addressable Detection

800 series Addressable detectors are intrinsically safe and use galvanic isolators when connected to the MZX loop. Galvanic isolators do not require a high integrity earth connection as the primary and secondary circuits are not directly interconnected.

This offers the installer a much easier and less costly installation and removes the need for regular checking to ensure continuous earth continuity. Available detection technologies are multi-sensors, smoke/heat detector, carbon monoxide/heat detector, ionisation detector, heat detector and the single channel IR, point detector. Each sensor offers flexibility in programming and offers various modes of operation which can be selected to suit the risk. All detectors connect to a common intrinsically safe approved base and have ATEX and IECEx approval for use in both gas and dust atmospheres.

Intrinsically Safe Conventional Detection

System 620 provides a range of conventional detectors very similar to the 800 series addressable. Conventional detection circuits also require a safety barrier, galvanic, (for new systems) or shunt diode (for extending some older systems), in order to meet safety requirements.

Conventional detectors can be connected to an appropriate approved control panel or an interface and onto an MZX loop, within an adjacent safe area. Within the product range are multisensors, smoke/heat detector, carbon monoxide/heat detector, ionisation detector, heat detector and the single channel IR, point detector. All detectors connect to a common IS labelled base and have ATEX and IECEx approval for use in both gas and dust atmospheres.

Meridian Fixed Gas Detector (SIL2)

Scott’s Meridian Universal Gas Detector is an innovative next generation gas detection solution. Meridian’s single detector head supports combustible and toxic sensors. Designed for ease of use, Meridian significantly reduces upfront investment and on-going maintenance costs. With global approvals and SIL2 certification from TUVRheinland, Meridian ensures best in class performance and safety.

The Meridian Universal Fixed Gas Detector can interface directly with MZX and ZETTLER PROFILE fire detection and alarm systems using the DDM800 Fire and Gas Module, to provide an economical combined fire and gas solution. Industrial facilities protected by MZX and ZETTLER PROFILE fire detection and alarm systems often have a requirement for gas detection.

Employing the fire detection system’s high-quality cabling infrastructure to also communicate toxic or flammable gas hazards provides a practical and economical means of achieving total environmental protection.

IR Oil Mist/Smoke Detector

The Tyco IR6003/7 Oil Mist/Smoke Detector has been specially designed to be highly sensitive to the presence of oil and kerosene mists or smoke particles in the path of the detector beam.

The detector has been developed for use in enclosed oil rig well head areas, generator rooms and turbine enclosures.

Callpoints

Tyco offer a range of hazardous area callpoints. Both indoor and outdoor Call points are available for use in hazardous areas. Alternatively suitable non-addressable devices can be connected to the MZX loop via an addressable interface.

Manual call points are themselves simple devices and can be connected via a galvanic isolator, or be constructed so as to be incapable of causing ignition, or be enclosed within a flameproof enclosure. In addition to the type of protection offered the device is also rated for use in a particular (gas group) atmosphere and temperature rated so as never to exceed the ignition temperature of any gas or dust /air mixture present. MZX offers the widest range of call points and interfaces to meet the required standard whilst minimising the amount of equipment to be installed.

Sounders, Beacons and Accessories

The MZX range offers sounders and beacons which are either intrinsically safe, when used with an appropriate safety barrier, or flameproof in their construction. A number of I/O units mounted within flameproof enclosures complete this very comprehensive range of hazardous area equipment.
