528t for extra sirens

How do i wire in a 528t so that when i arm my alarm the interior sirens don't chirp and only go off when the alarm gets set off? Black w/stripe-trigger input (which trigger?) Black-ground Red-12v Orange 87a-? Brown 87-? Yellow 3o-? Where does the red wire from sirens go?"ole blake"

My system does not have a horn output."ole blake"

You make no mention of what system you have, but if it provides an armed output use that to trigger the 528t. Cut the wire supplying the siren and connect as follows. 528T               Connection Red                 Constant fused 12V+ Black               Ground Orange 87a          One leg of interior siren supply Yellow              Other leg of interior siren supply Black w/stripe      Ground when armed output from alarm Set your timer for however long you want the interior siren to be disabled for. This will disconnect the siren supply each time the ground when armed output of the alarm is activated. Hope this helps.

Oh i'm sorry.I have a clifford arrow 3.It has a (-) armed output"ole blake"

So orange 87a will be the piezo siren (+) wire and yellow will go to the piezo siren (-) wire?"ole blake"
