No the low volatge(door bell, electric strike ) and hi voltage(120 volt) must be kept separate. They can be in the same trench right beside each other. They just can't be in the same conduit.

Also you shouldn't be runing 14/2 cable in the conduit. You should run individual conductor THWN.

thanks i will run them seperately can u explain why not so i can now the downside to doing so

thanks again

It is against code.

The likely reason is because in the event os a wire failure you do not want the possibilty of putting 120 volts on the low voltage door bell and stirke wires.
