Did you add an ignition or starter interrupt relay? If so and if you used a constant 12V source instead of an ignition 12V source for the relay, that would be enough to drain the battery.

If it has a built in relay, use it and make sure you connected the ignition input of the alarm to an ignition 12V source (wire only shows 12V when the key is in the on/run position). Did you connect any other accessories or relays? If so, please list them.
