Universities, multi-room gas monitoring, car parks, battery stores, battery charging rooms, food processing, agricultural buildings, banks and secure buildings are all examples of where the Pro-elite has been installed to provide a comprehensive level of gas detection.

Flexibility
The Pro-elite has been designed to be as flexible as possible, whether it’s a simple installation requiring just one detector or a large distributed system with a mix of gas detector types, alarm settings and remote indications. The system will be preconfigured before supply and require fully commissioning by Medem engineers.

IMPORTANT – Gas Detectors should not be installed until all building, construction or painting work, etc. Is completed, as these works can affect the sensitivity and longevity of the detectors.

Currently, they include:

• Methane CH₄ (natural gas)
• Propane C₃H₈ (LPG)
• Carbon Monoxide (CO)
• Carbon Dioxide (CO₂)
• Oxygen O₂ (both for enrichment and depletion)
• Hydrogen (H)
• Chlorine (CL)
• Nitrogen Dioxide (NO₂)
• Hydrogen Sulphide (H₂S)

Coming soon:

• Ammonia (NH₃)
• Acetylene (C₂H₂)
• Phosphine (PH₃
• Pentene (C₅H₁₀)

Detector Siting
When considering the placement of fixed-point gas detectors several factors must be taken into consideration including (but not limited to):

• The gas type.
  
• What the potential source is.
• The shape of the area i.e. roof peaks or sunken areas).
  
• Obstructions that could lead to “dead spaces”.
• Thermal links, remote EM stop buttons and a fire alarm input can all be monitored.
  
• Airflow – either natural or mechanical.

The underlying point is that the gas must reach the sensor in order for it to be detected, therefore each installation must be considered on its own merits and the information contained here is to be used as guidance only.

Carbon Dioxide
Medem's CO₂ detection is designed to deal with its production either via cooking or biological processes (namely breathing).
CO₂ is roughly equal weight and density as air it will therefore naturally diffuse equally within a space. Our CO₂ detectors are for the purpose of monitoring the air quality within an area to ensure adequate ventilation is taking place, as such the detectors should be located with the main body of the room within the “breathing zone” (4 to 8 feet) but not in such a place they'd likely be exposed to a potential release point (i.e. someone breathing on it). The alarm levels are dependent on application with different levels being specified for education facilities and for commercial kitchens, these are set within Medem's control panels and not the detector themselves.

Methane
A colourless gas which is a lighter than air gas and will, therefore, tend to rise when released to the atmosphere. Detector location should be at a high level. Detectors are set to alert at a pre-alarm level of 5% LEL and high-alarm of 10% LEL.

Propane
A colourless gas which is heavier than air gas and will therefore sink and stay at a low level when released to the atmosphere. Detector location should be at lower levels (approx 20 cm to 30cm from the floor). Detectors are set to alert at a pre-alarm level of 5% LEL and high-alarm of 10% LEL.

Carbon Monoxide
A colourless and odourless gas CO is roughly equal weight and density as air it will diffuse equally within a space. That said CO is typically produced as a product of poor combustion and as such can be initially excepted to rise as it will be hotter than the surrounding ambient temperature. Detector location is normally close by (but not immediately next to) the potential source – be that a boiler or ducted vent etc. Detectors are set to pre-alarm at 80ppm and high-alarm at 100ppm.

Oxygen
Oxygen forms some 21% of our atmosphere. At Medem, we primarily deal with oxygen depletion with a pre-alarm at 19% and high-alarm at 18%.
Although we have produced detectors for oxygen enrichment alarm levels would have to be decided on after discussion of the application.

The recently updated V4 system can monitor for carbon monoxide (CO) and carbon dioxide (CO₂) out of hours so even when the panel is switched off an alarm can be raised, or ventilation switched on. This provides additional safety monitoring particularly if solid fuel appliances are installed within the kitchen.

Demand-controlled ventilation fail-safe gas valve and relay checking are just some of the new developments making Medem systems continue to be the most reliable, safest and flexible available today.

With each gas line controlled individually, laboratories with multiple gas lines no longer need several panels installed. This reduces installation and purchase costs and creates a simple interaction for the user, which is aided by hidden until lit switches.

Detection of exotic gases can also be monitored.

All features of the system can be enabled during the initial installation, or they can be introduced at a later date, thereby providing a unique level of future-proofing.

Service Isolation
Isolation control of electrics, water valves and non-proving gas valves can also be achieved.
