The Appendix 1 and Appendix 2 are pneumatic sirens made by German manufacture Pintsch Bamag. The Appendix 1 is the first version which had a taller head and had its engine room bunker off to the side. Then later the Appendix 2 came out and had its engine bunker at the base of the tower. This siren works the same as all the other German pneumatic sirens. A bunker at the base of the sirens tower has a diesel engine that powers an air compressor and generator. The air tank in this siren is mounted inside the center of the sirens tower ,unlike outside like the HLS F-71 ,or inside the bunker like the HLS-273. There are only two of these sirens active ,which are Appendix 2s. All the others have either have been removed ,replaced with a Hormann ECN ,sitting abandoned ,and some have had radio antennas mounted on them.

Base of the Appendix 2 tower. The door leads to a ladder ,and down the ladder is the engine ,generator ,and accumulators.
