The Lu-Tech AB-3 General Emergency Siren is a multipurpose battery-operated warning beacon that acts as the new first line of emergency response used by Lu-Tech. This new alarm strobe has 8 powerful LED lights arranged in an octagon instead of the standard rotating klaxon used previously. This allows the beacon to not only change color to indicate specific emergency triggers but also have separate modes and flash patterns programmed into the alarm. The beacon comes with 4 pre-installed modes: Strobe, Single rotator, Double rotator, and Flash, however the possibilities for alarm patterns are only limited by the installer. The casing is made of aerospace-grade aluminium (and comes in a heavier full steel version for extreme environments), and the device has an internal battery that allows it to continue running even during total loss of power for up to 6 hours. The alarm comes in both wall-mounted and ceiling-mounted variants.
The alarm is purely variable operated, use the sliders to control the alarm Alarm sounds from freesound.org If you want to use this: ask first, clearly credit me, and make sure to link the project you used it in!
