Dear All,

From some time I try to understand DD243:2004 requirements, yet have some unexplained doubts. First of all, the "completion of setting". I couldn't find any information on what should happen if the "completion of setting" procedure will not be performed (e.g. "push set" button will not be pressed after typing-in the code for setting). Should the system set after the exit delay expires (and "push set" only terminates the exit delay before it expires), or should stay in a "ready to set" mode (but then, how to notify the user that the procedure haven't completed - in case the button is not operating, for example).

Second question is related to "remote reset" feature. How the code/anticode algorithm is provided - is there an UK-wide standard for that, and all the equipment manufacturers use that or, each manufacturer provides the ARCs with their "anti code calculators" (software or hardware)?

Many thanks for helping me out with these.

Best regards,

Michal

Dear All,

From some time I try to understand DD243:2004 requirements, yet have some unexplained doubts. First of all, the "completion of setting". I couldn't find any information on what should happen if the "completion of setting" procedure will not be performed (e.g. "push set" button will not be pressed after typing-in the code for setting).

If the exit terminator button is not pressed the exit tone will not stop and the system will not set, it is always recommended that when a system is set the customer should wait outside the premises for the exit tone to stop so they know the alarm has set OK.

Second question is related to "remote reset" feature. How the code/anticode algorithm is provided - is there an UK-wide standard for that, and all the equipment manufacturers use that or, each manufacturer provides the ARCs with their "anti code calculators" (software or hardware)?

The anticode is generated using specialist software only available to alarm companies. Most manufactures use the own software; some use a specialist system like technistore that I assume is sold on licence to some manufactures.
