Fire alarm systems need to be inspected, tested and tagged annually. Testing must include all smoke detectors, manual pull devices, annunciators, visual indicators and strobes, control units, voice/alarm communications systems and any other devices that are a part of the fire alarm system.
it will need a port like this one to get more power from the usb since it only give 5.0 volts and this powered usb give up12 to 24 volts so you dont have that in a laptop and there is no way it could raise the power on the usb port in a laptop without damaging something .http://en.wikipedia.org/wiki/Powered_USB.
Ad. 2. Insert the USB drive into the port. If you plan to use it frequently, insert it into the front port. Make sure you insert it into the correct port-some desktops and laptops have different types of ports available, such as 2.0 and 3.0 ports, which could be hi-speed and non-hi-speed ports. Proceed accordingly.
