Alert lights with sound options

Called Stacklights, they mount with an M22 thread through a 22.5mm hole. Some versions have the lights just above the mounting surface and some are extended 100mm above the mounting surface (see photo, tall lights are further away).

After colour choice, a further option is to have a 3.9kHz sounder built in (sounder versions can only be red or green or both – no yellow options).

“he new alarm produces a clear sound, superior to that of electro-magnetic or electro-mechanical alarms,” according to New Yorker Electronics which is stocking the lights. “Stacklights with sound are available in continuous tone, chime tone, fast pulse, medium pulse, slow pulse, fast double pulse and slow double pulse.”

Some sounder versions keep going, and others switch to a repeated short pulse sound after 15 seconds. Some versions are medium-loud (70 to 80dB typ at 1m), and others are loud (80 to 90dB).

Sound and lights are separately controlled.

There is also a choice of operating voltages, with some Stacklights working across 9 to 16Vdc (JR-16 Series), and others 20 to 28Vac/dc (JR-28 Series). The internal LEDs draw different amounts – some as much as 60mA.

Cables are around 300mm long.

Applications are expected in scientific equipment, medical equipment, 3D printers, machine tooling and robotics.

The parts are cUL recognised and RoHS compliant.
