This inspection need not be recorded.
b) Every week, an outstation should be operated. It should be confirmed that the call is correctly received at the master station and that a short test conversation is clear and intelligible at both master station and outstation.
c) A different outstation should be used at the time of every weekly test, so that all outstations in the building are tested in rotation. The result of the weekly test and the identity of the outstation used should be recorded.
28.2 Recommendations for monthly attention by the user
a) If an automatically started emergency generator is used as part of the secondary power supply to the EVC system, it should be started up once each month by simulation of failure of the primary power supply and operated on load for at least one hour. The test should be carried out in accordance with the instructions of the generator manufacturer, including instructions on the load that should be operated. At the end of the test, the fuel tanks should be left filled, and the oil and coolant levels should be checked and topped up as necessary.
