Hi,
I have recently had to replace my existing Cequra sounder / bell-box with a replacement item, i.e. a Cequra2 unit.
These are the connections used on the original unit (no resistors fitted).
So I though I\'d be able to simply transpose these same connections to the Cequra2 unit as follows (note, some of the connection naming is different on the Cequra2).
Again I didn\'t fit any resistors.
When testing I experienced two issues, the strobe was on permanently and the siren wouldn\'t sound. After some experimentation I fitted a pair of 1K resistors (between the +ve Hold Off and Siren & +ve Hold Off and Strobe).
This has fixed those issues and both the siren/strobe now function as expected.
However I still have an issue with the \'cheep-cheep\' arm notification which I used to get when full-arming the solution. This is still not working. I really want this to work, since it\'s a very good arm-notification indication.
Any ideas appreciated.
FYI, on the Cequra2 the unit is configurable for +ve/-ve strobe & alarm configuration, I have left this as default (i.e. -ve).
Also (for reference), what\'s the meaning of \'trigger wire monitoring facility\' since the Cequra2 instructions show two connection methods, one without this and one with it? FYI I have used the \'without\' option.
