After every 70 times the system has been unset, the system will prompt you to test the system. The results of this test are stored in the panel and form part of the service report generated by the ARM maintenance computer

To Continue with the test press 'YES'.
(If you choose 'No' you will be asked again to perform the test the next time you unset your system. After rejecting the test three times you will not be asked to perform the test for another period of 70 system 'sets')
