[1] The strobe must be connected to a continuous voltage. The horn
must be connected to a continuous voltage when it is set to sound a
temporal tone; it may be connected to either a pulsed or continuous
voltage when set to sound a steady tone.
[2] Horn and strobe currents are additive when connected in parallel.
