Rather than use a bulky transducer + amplifier + room speaker system to make the very high-pitched, low-volume sound louder within the room, simply use an inexpensive in-ear "personal sound amplifier" while you enter the code. Place the device on a hook/nail on the wall next to the home security system unit when not in use.
The device is not a proper hearing aid, and it's not a bluetooth device; it's a cheap sound amplifying earpiece with poor fidelity, but plenty of gain.
