MAINTENANCE For proper operation of the detection system which also includes the controller it is requisite to periodically undertake specifically the following servicing of the transmitters connected to the controller a calibration at least once every 6 12 months i e setting the detection limits checking the responsiveness of the sensor checking the system s functionality The precise interval is dependent on the level of contamination of the environment the degree of accuracy required and the level of occurrence of the selective gases in the environment Calibration should be carried out only by authorised service centres holding a valid certificate of competency or by the manufacturer b Functional checking at least once every 3 12 months Functional checks are performed utilising the test gas at the concentration that is intended for it this must not exceed the limit range of the transmitter We recommend gases with a certified 1st grade of purity Recommendation For ideal functioning it is recommended to carry out the calibration and the functional checks once every 6 months or the calibration once every 12 months and the functional check once every 3 months The means for testing the fire alarm transmitters must not be utilised for these checks v APPENDICES Appendix No 1 Example of the connection of the DEGA UPA II L compact controller
