has_many :through question

I have 3 models

Circuit has_many :alarms has_many :dacsports, :through => :alarms

Alarm belongs_to :circuit belongs_to :dacsport

Dacsport has_many :alarms has_many :circuits, :through => :alarms

I have the circuit -> dacsport relationship going.

How do I correlate the alarm data to either the circuit or the dacsport?
