If the fuse blows in your Code 3 Security System, it usually means the amplifier power wires have reversed polarity. To fix this, check the polarity of the wiring.
Why does my Code 3 Security System siren go off by itself?
If your Code 3 Security System siren is sounding on its own, it's likely due to a short in the remote switch (horn ring) wiring to the remote input, causing it to short to positive or ground. Check the wiring for any shorts.
How to fix no siren output on Code 3 Security System?
If there is no siren output from your Code 3 Security System, it might be due to a shorted speaker or speaker wires, which puts the siren in over current protection mode. Check the connections to resolve this.
Why are the siren tones too low or garbled on my Code 3 Security System?
If the siren tones volume is too low or sounds garbled on your Code 3 Security System, it could be due to: * Low voltage to the siren amplifier. Check the wiring for bad connections and the vehicle charging system. * High resistance in the wiring or a defective speaker. Check the speaker wiring and replace the speaker if needed.
What to do if there's no output from the speaker on my Code 3 Security System?
If you hear tones inside the amplifier module but there's no output from the speaker in your Code 3 Security System, the issue might be: * The speaker is not connected, or the speaker wiring is open or shorted. Check the speaker wiring. * The speaker is defective. Disconnect the speaker and listen at the siren for tones. Replace the speaker if necessary.
Why does my Code 3 Security System have a high rate of speaker failure?
A high rate of speaker failure in your Code 3 Security System could be caused by: * High voltage to the siren. Check the vehicle charging system. * Connecting a 58-watt speaker to a 100-watt tap. Using a 58-watt speaker is not allowed; use the correct speaker.
What to do if the PA works but the siren doesn't on my Code 3 Security System?
If the PA system operates but the siren won't run on your Code 3 Security System, it could be: * The vehicle is in park; the park kill feature mutes the siren while the vehicle is in park or neutral. Put the vehicle in gear. * The RRB switch is on. Turn the RRB switch off.
Why is the P.A. volume low or not working on my Code 3 Security System?
If the P.A. volume is low or there is no P.A. at all on your Code 3 Security System, even with the volume control at maximum, it could be due to: * A defective microphone. Replace the microphone. * The maximum P.A. volume trimmer is misadjusted. Refer to the operation section.
