Hi there, I recently purchased an AR timer on eBay and I was having similar issues. Here's what I would do.
Power not going to the siren: keep in mind that AR timer does not give any power to the siren, it is basically just like a switch or relay. You'll have to get power to the siren separately.
Test button: the wires coming out of the test button should be going to terminals 1 and 2 on the lower Bank, On my timer the wires are orange and purple. If the wires are going to these Terminals and the problem still persists then the button has most likely failed, Or the timer was wired incorrectly.
Cancel button: keep in mind that even after the cancel button is pressed they cam motor does not stop, and will continue to go for the full 3 minute cycle but, the siren should stop after the cancel button is pressed.
The timer may also not be working properly because it was connected to a radio activation system while it was in service (mine had this problem) if so, you will need to add some jumpers to the timer. Those jumpers are between 15 and 16 on the upper Bank and between 13 on the upper bank and 6 on the lower Bank.
Here is schematic that shows how I wired my AR Timer with my Model D.
