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.

All Medem control panels have the capacity to be connected to a fire panel, so in the event of an alarm, our systems can isolate the gas supply.

Although a vital safety feature it can prove inconvenient when testing and servicing the fire alarm system.

The FTIP-1 is designed to sit between our standard gas control systems and the fire alarm panel. When activated it will isolate the two systems from each other allowing the fire alarm to be tested without interrupting the gas supply.

This is a key controlled and timed (max 45 min) isolation, that if not manually reset will do so automatically after the period set during installation.

Please Note:
FTIP-1 function is built into the SEC range of panels.

Flexibility
Each CM2M-K can be used to interlock 2 fans, the fans are connected by taking the live feed for each fan through the current monitor (before any speed controllers/inverters).

Fan load sensitivity range on each fan is 30 milliamps to 24 amps (max).

Features and Details:

• There are 3 LED indications:
     > 1x Green, for the 12-volt power to the CM2M-K.
     > 2x Red, one for 'Fan A' and another for 'Fan B' load detection.

When the fans are switched on and the load is detected (installation instructions) the corresponding side’s NO/NC contact will close and the red LED will light, this will flash for the first 15 minutes after current detection and then become solid. The flashing LED helps us to identify a fan intermittently stalling.

The gas pressure proving is by Medem’s patented method of dynamically measuring the pressure differential across the solenoid valve when performing a downstream integrity check. This method stops nuisance tripping of the gas supply. The addition of the LCD makes this system very easy to use providing clear messages giving real information rather than just LED indications.

Flexibility
The GPPS-evo is designed to perform a downstream integrity check of pipework and appliances which could be left open to atmosphere, such as a laboratory.

In-line with the updated legislation of BB101 and IGEM/UP11/Edition 3 the system can also monitor the CO₂ level when fitted with a Medem detector displaying the PPM.

CO₂ is considered a primary indicator of air quality, with the latest legislation setting maximum limits for levels within educational facilities.

Carbon Monoxide, Natural Gas and Oxygen depletion detectors can also be monitored.

An auto-stop timer is incorporated to help prevent unauthorised use of the gas out-of-hours.

There are several 'engineer functions' which can be used to aid in the set-up of the system.
