SEC-K-NP- kitchen Interlock

SEC-K-NP- kitchen Interlock

The SEC-K-NP – kitchen interlock gas system. Ventilation interlock system with multiple features available where and when required

  • Ventilation Interlock
  • Carbon Dioxide level monitoring
  • Gas detection/Carbon Monoxide
  • Demand controlled ventilation
  • Dual BMS selectable relays
  • Built in fire test isolation control

Ventilation interlock
It is a requirement (See BS 6173/2009 & IGEM UP19/Edition 1) that any mechanical ventilation within a kitchen environment (supply and extract) is switched on and running before the use of any gas appliances can take place. If the ventilation is not switched on, the LCD display informs the operator of the fans that are off, to switch them on and reset the panel.

Carbon Dioxide monitoring
When fitted with CO2 detectors, the SEC-K-NP can provide catering staff with information based on the room ventilation quality. This can be used to remind staff to clean any fan filters or increase the ventilation during higher levels of occupancy or cooking load.

Demand controlled ventilation
The SEC-K-NP can monitor the carbon dioxide level and temperature to control area ventilation in commercial kitchens.
This enables energy and cost savings because the ventilation rate is adjusted in relation to demand. Where the CO2 level rises above prescribed limits, the system can isolate a gas supply.

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

  • 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 activation

    CO2 based ventilation activation

    When fitted with the additional BMS relay, a signal can be taken to a contactor to switch on a fan when a set level of CO2 has been detected in order to control the ventilation rate.
    This can help to save energy by controlling fans so that as the occupancy rises and falls so will the ventilation rate.

  • 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.

  • Electrical Isolation

    Electrical Isolation

    Option to control the electrical supply via a contactor, this allows a single point of isolation for multiple services

  • 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)
