BURGLAR ALARM QUESTION I have installed a new AZTECH AZ-220 bell box as per instructions, it is wired correctly ( I think! the previous unit was an older aztech which had to be replaced following storm damage), and went to muted state when activated, however I can get no response from a function test from the panel for strobe or sounder), and the LEDs indicate that the unit is still in muted state even though I have 13.7V at the terminals in the box, the only function working is the tamper switch. Is the unit defective or is there another test I can try?
Is there any test I can make to the unit, before I go out and buy another?
As I bought the unit by mail I would like to be absolutely sure before I throw even more money away sending it back so that somebody can throw it in the bin!
As I said in my initial question, I have 13.7V at the bell box terminals, as I understand it, the 12V DC voltage into the box is constant and the panel switches it on at the two returns for the strobe and sounder for an alarm trip. The maintained voltage 'holds off' the boxes own 6V anti-tamper response, but only once it is activated by the higher voltage from the panel, am I correct in this assumption? If I am right then, the box must be faulty.
Yes they are very reliable, the last one was working just fine right up until a falling tree knocked it off h the wall it was on!
Thanks a lot for your help.
