DESCRIPTION

The E2452 is a standalone lost RC aircraft 
beacon module which produces a loud 
beeping sound after a programmed time 
delay has elapsed or when triggered from a 
spare receiver channel.  The programmed 
time delay varies between 1 to 72 times 20 
minutes after being powered.  This allows 
aircraft to be flown for regular flights before 
being reset unless the aircraft does not return 
in time such as due to a crash.  Alternatively, 
the beeper can be enabled using a spare 
receiver channel prior to the time delay 
elapsing.  Unlike other lost aircraft beepers, 
the E2452 module does not depend on a 
possibly non-functional receiver to power 

the beeper after a crash.  The E2452 module 
instead uses a self-contained battery to sound a
beeper for 1 second on and 10 seconds off to 
prolong battery life for over 24 hours while a 
search is in progress.  A battery monitor beeps 
between one and five times to indicate battery 
strength.  The modular form also minimizes 
the chance for damage after a crash.  The 
beeper is very loud thus increasing the chances
of recovering an aircraft in dense bush.  The 
module can be attached and transferred to any 
aircraft.
