0249-0449 *LA not observing - power loss caused fire alarm       11858  100  120
           - alarm triggered the shunt trip. Fire department                    
           on site, no fire found. Initial alarm was @ 0213UT.                  
           UPS power failed at appx. 0240UT.                                    
           Fire department returned to station to                               
           investigate new alarm, probably due to UPS failure.                  
           Receivers were warming at last check before comm                     
           failed due to loss of UPS power.                                     
           Sensaphone called for both fire alarm and UPS                        
           failure - helpful little fellow, but could use more                  
           personality.
