The siren has 12 volt supply to the box. The alarm controller states that the contacts have to have zero voltage.
Where does it state this? On the unit?. The alarm controller states that the contacts have to have zero voltage.
The alarm control unit instructions state that it's Relay contacts, to trigger external siren must have no voltage across them. The external siren needs 12 volts from the control panel to trigger the siren.If the "contacts have to have zero voltage" then I don't see why you would connect 12V to them?
The alarm control unit states that the built-in external alarm Relay contacts either no or no must have no voltage across them.Where does it state this? On the unit?
Or do you have hook up instructions, or any other details?.

I should point out that my alarm is not listed in the siren booklet but I would think I could use the general connection listedDoes it show any hook-up details?

The specification "Latching relay contacts (volt-free)" doesn't mean that the contacts must have no voltage applied: it means that the control unit itself doesn't supply any voltage to the contacts. It's your decision what use you make of the contacts.The alarm control unit instructions state that it's Relay contacts, to trigger external siren must have no voltage across them.
Sorry I never sent the text that was with the the Alarm panel connection block...The specification "Latching relay contacts (volt-free)" doesn't mean that the contacts must have no voltage applied: it means that the control unit itself doesn't supply any voltage to the contacts. It's your decision what use you make of the contacts.
I assume that infers that no external voltage is required and contact closure only is required between input points.
They appear a little vague and certainly could be clearer.

Sorry Section should readI agree that it could be better and maybe I need to talk to Honeywell.
I have 12 volts at the siren box and I did not think I could run it through the control box NO snd the when the alarm is triggered the co tacos would close sending the 12 cold to the siren. On cancelling the alarm the siren would cancel!
But the wording made me think that I needed an interface that would supply the 12 volts to the siren from either an open or closed contact from the panel.
But I have no idea what circuit/inyerface I should look for that would not put voltage across the contacts.
As Alec noted, that's referring to the external signal contacts, such as from door and window sensors, not for any output contacts in the alarm.This is were I got the idea that I could not apply a voltage across the contacts.
Thanks again for the help. What I maybe should have said was the the alarm system has its own solar powered wireless siren and over the last few years I have noticedTo me it would seem that especially a Co. such as Honeywell would show a much clearer and detailed typical hook-up.
The instructions are far from clear and certainly not typical, IMO.
