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?

if your alarm has a horn output you can use that it turns on only when full trigger......

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.

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