These 12V dc operated units simulate the sound of a two-tone British style loco horn. Each features pitch and duration controls for each note, plus a volume control.

Unit may be used free standing, or mounted within the loco (O gauge and larger). It operates on 12V d.c., provided by batteries or any d.c. power supply, and is supplied complete with all the necessary switches.

Supplied with 50mm, 8 ohm round speaker, and comprehensive installation instructions. Up to two extra 8 ohm speakers can be added in parallel for extra volume if required.

The effect is triggered manually at any time via a push switch, or automatically via a train mounted magnet passing over a reed switch positioned between the rails.

Module dimensions: 110 x 60 x 25mm.
