in the same raceway.
130vdc is for a door alarm and 24vac is air conditioning controls.
Can I do this or am I mixing class1 and class2?
 
Voltage and insulation type for the conductors are not the only determing factors in regards to conductors from different systems installed in the same raceway/enclosure.

As you mentioned, the source is important as well, such as Class 2.

The source for the door alarm is a 130 volt dc 20 amp breaker in a panel fed by a 130 battery string. The 24 vac source is a control transformer in the air conditioner.
Or do I not understand what you and Raider are asking me?
 
The 24 vac from the air conditioner is probably from a Class 2 power supply and the rules in 725.55 will very likely will prohibit the mixing of those conductors with those of the 130 volt system.
