Close the gas appliance and re-test the gas.. The gas test should successfully complete, if the gas
test fails and you have checked all appliance are off you have a gas leak and require a gas
engineer to check the pipe work..
With the gas proven and available for use, breathe onto the CO2 sensor (where fitted):
The system will indicate a rise in CO2 and advise the operator to increase any available ventilation.
Or the SEC-K system will attempt to increase the ventilation (where the feature has been connected)
If this is not done and a level of CO2 remains present at the sensor the panel will go into a high
alarm condition and isolate the gas supply.
The systems are currently set to 2300ppm low alarm and 2800ppm high alarm.
All of these procedures are dynamically carried out by the SEC-K system each and every time it is
switched on. The system should only be turned on during service and switched off when the gas is
not in use so the gas supply remains isolated.
There should be a manual operational test on any installed Emergency stop buttons, which when
operated will isolate the gas supply and remain isolated until a manual reset is completed.
If utilized an auto stop time out will isolate the gas after the set period (default disabled).
A yearly test and inspection of the solenoid valve and let by test should be carried out by a qualified
technician i.e. Gas safe registered engineer.
The system should be switched off using the main system on/off switch at the end of a service so a
new pressure test can be completed ensuring there are no leaking appliances or appliances left
on.
Due to the Medem SEC-K being a digital system that checks its self every time it is switched on
there are no recalibration requirements.
If fitted the detectors are designed to have very low drift so recalibration on site is not required but
should be replaced every 5 years in a clean environment but consideration should be given to
replacement after 3 years if contamination is a possibility. A functionality test should be carried out
every 6-12 months.
The gas and electric supply are controlled by the soft touch switches after the panel has been
enabled with the system switch position set to ON
If at any time there is an alert or the sounder sounds follow the on screen instructions,
further information can be found both in the installation instructions and by contacting
