Thunderbolt 1003 all 3 Signals
THIS IS THE OFFICIAL AND ORIGINAL VIDEO I HAVE, NOTE: THIS IS NOT MY VIDEO!!!! i uploaded this because the user of this video deleted the video due to, too many bad comments on videos (that's what i heard) but i won't let this get out of hand and so i uploaded it so u guys can watch it as well any questions, comment below or send a massage i do read your comments so no negative crap FIRST signal is fire, high low, is sirens that use solenoids to block the air in one row of ports/openings preventing that tone to sound thus only the other row will sound as long as it is not blocked and "hi-lo" is created with that cycle repeating how fast it is set to SECOND is called alert, popular for warning others, for a tornado/testing, its where the tone is steady THIRD is called attack, popular for firehouses that don't have sirens with solenoids, used as well as some siren testing after alert there are a couple more signals but they would have to be rewired to make the signals ALTERNATING HI LO (solenoids in hi lo mode non-stop with attack mode) my personal favorite this signal is semi rare to find since most tbolt/3T22 have the hi low for alert rather than attack. this is unique because with the hi low still activated while in attack changes the tone each time the solenoids are activated. PULSED (friend's favorite) this signal is also semi rare to find. this is done by having the 2 solenoids wired to the same terminal connections in the control panel. this will make them open and close at the same exact time. (like binary On or Off) you get Pulsed sound while in alert ALTERNATING PULSED this is rarely used. this is the same as Pulsed (see above) but instead of running it on alert, you run it on attack and the solenoids still switch while the rotor winds down and winds up if i missed a signal or correct my description, feel free to comment below
