- had to reprogram this thing to actually do voice messages as well as map the test message to the button on the front panel, since the people who installed this and the rest of the sirens in this county never bothered to program them correctly. one vortex R4 in particular was reprogrammed by the installers, as a R3 so that the EMA wouldn't receive the warning of the one bad amplifier.
