The SEC-L, a multi-function solution designed for the laboratory

  • Gas pressure proving
  • Gas detection
  • Electrical and Water isolation
  • Demand controlled ventilation

Gas proving
Using the patented differential pressure proving method, the SEC can test low pressure gas and natural/LPG gas pipe work. It can also pressure prove a variety of gas delivery lines including oxygen up to 10bar. Overpressure can also be monitored and reported on the LCD display.

Gas detection
The SEC has been designed to accept multiple gas detectors including natural and LPG gases, carbon monoxide, oxygen depletion and rise, as well as CO2. Isolation of gas will occur upon detection of the target gases at prescribed levels.

Demand controlled ventilation
The SEC-L can monitor the carbon dioxide level and temperature to control area ventilation in the laboratory. Where the CO2 level rises above prescribed limits, the system can isolate a gas supply. The limit is variable to accommodate for current legislation and guidance. See BB101 for more information.

Design & Specification Documents

  • 5 Year Warranty

    5 Year Warranty

    Medem’s industry leading five-year warranty is a demonstration of the company’s confidence in the quality and design of our products.

    This applies to the main panels and sender units, gas detectors carry a two year warranty.

    Where we commission an installed system the warranty is extended from five to ten years. At the time of commissioning photos and gas pressure readings are recorded along with other relevent details of the installation. A 24 hour help line number and serial number is attached with the panel and all details are then entered on to the Medem database.

  • CO2 based ventilation control

    CO2 based ventilation control

    A 0 to 10 volt output on the panel can be connected to fan speed controllers in order to control the ventilation rates based on CO2 and temperature levels.
    This can help to save energy by controlling fans speeds so that as the occupancy rises and falls so will the ventilation rate.

  • Engineer Functions

    Engineer Functions

    Our systems include several engineer functions which allow a range of information to be displayed on screen.

    This not only aids in the original setup and commissioning but also enables us to provide a greater level of technical support on the telephone.


  • Fan interlocking

    Fan interlocking

    Fan interlocking is used where you require isolation of the gas supply when the ventilation is not running.

    In commercial kitchens it is a requirement to meet current regulations BS6173, BB100, UP11 (see our standards section for more information).

    Our recommended method of interlocking is “current monitoring” (see our model CM2M-K)


  • Fire Test Isolation Mode

    Fire Test Isolation Mode

    Fire Test isolation; In the event of a fire alarm test being undertaken the system can be set into a fire test isolation mode with three consecutive presses of the display detectors button (indicated) so ensuring the gas remains live during the test procedure.

    Once the test is completed the panel will revert to normal operation. If at any time you wish to cancel the operation of the fire test isolation repeat the three button presses on the panel and the panel will once again be connected to the fire panel.

    Note. In the event of an emergency requiring the isolation of the gas supply whilst the fire test isolation function is active the emergency stop button on the panel (and any others fitted) will still isolate the gas supply.

  • Over Pressure Alert

    Over Pressure Alert

    New to our systems is an over pressure alert

    Should the gas pressure rise above 70 mbar while gas is being used the panel will isolate the gas supply by closing the gas valve.
    When the panel is first switched on and if at that time the gas pressure is over 70 mbar then the gas valve will remain closed.
    Only a Medem gas pressure proving system measuring pressure on both sides of the valve can operate in the way described.
    70 mbar is above the pressure most appliances and other equipment (in buildings) has been designed to use, higher pressures can occur where a gas regulator fails.

  • Water Isolation

    Water Isolation

    Option to control the water supply via a 230v solenoid valve, this allows a single point of isolation for multiple services.
