Narrative:

At XX26 uct, mia tower had a complete power failure which forced controllers to operate battery powered radios for several mins. We had 9 operational radar position and only 6 radios in usable position. 2 of the radios are located over the flight data position where there are no radar scopes and should be relocated. The radios are equipped with loud speakers and hand mikes and have no way of connecting to a headset. With 8 different loud speakers going along with the other confusion taking place it made it impossible to have effective 2 way communications with aircraft. I believe that all radar position should be equipped with battery powered radios and a device should be designed that allows the controller to plug in the headset to the radio to cut down on the confusion. During the outage there were not enough flashlights or note pads for controllers to properly perform their duties.

Title: PWR FAILURE MIA TWR TRACON.

Narrative: AT XX26 UCT, MIA TWR HAD A COMPLETE PWR FAILURE WHICH FORCED CTLRS TO OPERATE BATTERY POWERED RADIOS FOR SEVERAL MINS. WE HAD 9 OPERATIONAL RADAR POS AND ONLY 6 RADIOS IN USABLE POS. 2 OF THE RADIOS ARE LOCATED OVER THE FLT DATA POS WHERE THERE ARE NO RADAR SCOPES AND SHOULD BE RELOCATED. THE RADIOS ARE EQUIPPED WITH LOUD SPEAKERS AND HAND MIKES AND HAVE NO WAY OF CONNECTING TO A HEADSET. WITH 8 DIFFERENT LOUD SPEAKERS GOING ALONG WITH THE OTHER CONFUSION TAKING PLACE IT MADE IT IMPOSSIBLE TO HAVE EFFECTIVE 2 WAY COMS WITH ACFT. I BELIEVE THAT ALL RADAR POS SHOULD BE EQUIPPED WITH BATTERY POWERED RADIOS AND A DEVICE SHOULD BE DESIGNED THAT ALLOWS THE CTLR TO PLUG IN THE HEADSET TO THE RADIO TO CUT DOWN ON THE CONFUSION. DURING THE OUTAGE THERE WERE NOT ENOUGH FLASHLIGHTS OR NOTE PADS FOR CTLRS TO PROPERLY PERFORM THEIR DUTIES.
