Setting up rebroadcast

[nick223]

Trying to set up a siren box so the radio can go though the siren when switched to the radio button on the siren box. Using tk 7180s and tk 7360s
Also how to go off the radio to the back of the siren box.

any information in appreciated thanks.

All you need to do for radio rebroadcast on a siren unit is bridge across the speaker leads. Name brand sirens work with BTL audio so there is no damage to the radio.

If you use external speakers, no prob splicing into the wire. If you use the internal speaker, there's a hitch. If you terminate the sirens rebroadcast wires to a phone plug and stick it into the external speaker jack, it will kill the internal speaker. On a TK_X80 it was easy, just pull the cover and apply a solder blob to bypass the switching action. The TK_X180 would require you to pull the whole board up for this. Easier to snake the wire inside and go straight across the internal speaker.

There is AFO (receive audio) on the rear 25 pin connector, but it may not have enough oomph, depending on the siren.

Thanks for the reply.

Here is what we did took an external speaker cut the cord put both ends into the siren box and the speaker connection into the speaker jack on the back of the radio. This is what i was told to do by the radio guy at the shop he said its the easiest and cheapest way to do it and it works.

we been trying to adjust the RBB on the back of the siren box the thing is it is distorited on some of the radio traffic i know it wont sound crystal clear but is there anything we can do to get it a little better.

the louder the person transmit the better it sounds so if you have a quiet person talking its distorited. is this because the speaker is a siren 100w speaker? Not sure if you have any other advice

Thanks

Normally it just works. You adjust the gain in the siren to where it just becomes loud enough to be usable.

Is the audio out the external speaker distorted also, or just from the siren speaker? What brand of siren are you hooking this to?

just the siren speaker its a code 3 siren/speaker. the rest of the trucks works great because them are cone shaped sirens.
