Alarm Question

My '99 C2 Tip's alarm has been working fine, but when changing the car battery I noticed something strange. The horn next to the battery on the offside was buzzing slightly. I disconnected the connectors to the horn and tested the voltage which read 9-10v all the time. The horn sounded normally when I applied 12v through it. When I left the horn disconnected and armed the alarm, it rightly sensed a fault and the led flashed twice every few seconds. When I reconnected the horn, all was well when arming it. My worry is the 9-10v going through the horn all the time and would it flatten the battery. Is this normal or is this how the alarm system senses the horn is connected or not. I would appreciate if anyone out there has the same car would connect a volt meter to the connectors of this horn to see if they have the same phenomenon. Thanks

Thank you Tool Pants. Answers my question exactly. At least I know the 9.6v I read is normal and not some short circuit.
