What is the proper way to install a battery backup siren to an existing alarm?
I intially connected it to the +,- wires for the current siren and used the neg trigger line but when I activated the unit I was unable to shut it off using my remote.
Next I tried hooking it up directly to the constant +12v line powering the alarm and the ground along with the same neg trigger. It had more power and was louder but had the same result as before. Am I using the correct hook up? Should I be using a + trigger instead? What about this unit draining my battery, would a relay help somewhere in the install? I'm considering using this unit in addition to my current siren.
SOMEONE PLEASE HELP!
My current alarm is an Audiovox APS400 in my 2001 S10.
Thanks for your help.

the way they work, is the red to 12v...blk to ground....if the the power is lost the siren will trigger and run until the battery dies or you shut it off with the key.......if you use the purple wire (+)and hok it up the alarm siren output, the siren will trigger but not shut off until you use the key.....at least thats the way the ones from omega work...... ------------- Good Luck

What brand is the BB siren? How many wires are coming out of the harness?

I was told that it was a Crimestopper unit when I bought it off of Ebay. The unit has 4 wires. 2 are +,- and the other 2 are for +,- triggers. When I hooked it up initially it was using the +,- from the current siren which didn't seem to provide it with enough juice so I hooked it up to the same constant 12v feeding the brain and - .This way made it sound much louder so I assumed that this aspect of the hook up was correct. Now when I hooked up the trigger I spiced in to the - trigger being used by the alarm. I don't think the truck has a + trigger. Anyway, When this was complete I reattached the battery and turned the siren on using the key. It started wailing away and wouldn't shut down unless I used the key again. Meanwhile, during my failed attempts at using the alarm remote to shut it down, I could see the led for the alarm responding normally and flasing the parking lights twice as if the alarm itself was shutting down. Only thing was the siren wasn't. What an I doing wrong? This is really getting to me! Could someone please go to the audiovox website and click on installation manual and tell me what wires you would use to install this siren? I believe I used the brown wire for the - trigger. Thank you in advance for bearing with me. By the way the truck is a 2001 S10 4.3L. https://www.audiovox.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10001&storeId=10001&productid=608&langId=-1

thats the way it works. its not designed to work as the primary siren. when the alarm is triggered, you can send a - or + pulse to sound the siren. once it starts sounding, it will run until you use the key to shut it off. thats so someone cant cut the main power and shut the alarm down...... ------------- Good Luck

So are you saying that I hooked it up properly based on my description?

On the siren? I believe that they are blue and white plus the norm black & red. I am at work now and can't quite remember the color codes, but I believe blue is - trigger and white is + trigger.

Would this siren place a constant drain on my battery thus killing it? Are any relays needed in this system to prevent any problems? Please say no.

no. the siren will use the - or + to trigger it....it is not using the siren output from the alarm to power it......the back-up siren will run until the battery inside of it dies......not sure which one will die first...im sure it will be the siren one... ------------- Good Luck

The reason I am asking is that some of the models come with a 4 wire hook up and the others come with a 5 wire harness.
The standard CS211 is a 5 wire harness. The colors and use are as follow's.
1. RED = (+) 12 VDC constant
2. BLK = (-) Chassis ground
3. WHT = (+) Positive trigger
4. BRN = (-) Negative trigger
5. ORG = (+) Battery charge, with ignition on
Other models such as the DEI 515R have only a 4 wire harness.
1. RED = 12 VDC constant
2. BLK = Chassis ground
3. VIO = (+) Positive siren input
4. GRN = (-) Negative siren input
I would just like to clarify the operation of the battery back up siren for you. When you arm your alarm you will hear a chirp, when you disarm, you will also hear a chirp from the siren(s).
When the alarm sounds, both sirens should come on. When you disarm the alarm, both should turn off.
The back up siren should idealy function on its own, when power is removed, assuming the key is turned in the armed state. If the key is left in the off state, it will only operate as a normal siren without battery back up.
I would ask you to the do the following things first to varify the operation of the siren. With the back up siren disconnected from any source when you turn the key to armed, it should sound on its own, assuming it is properly charged.
If it does not, no matter the position of the override key. Then either the battery is too low, dead, or the sirens electronics are faulty.
If it operates normally as stated above, your next step is to ensure that you wire the siren correctly as outlined above.
Remember, the siren only uses a positive or negative input trigger from your alarm. Do not wire all four wires. In your example there would only be 3 wires in total connected.
That being +12 positive from the battery, (-) chassis ground, and a (+) trigger from the alarms brown siren output.
Again, the back-up siren should always turn on and off with the alarm system upon arming and disarming. The only time the siren will not turn off is (IF) the main power source is disconnected, or a low power condition is seen.

OK. The siren does sound when it's disconnected from any source with the key turned to arm. Now, when I connected it as described earlier and I armed it, I was unable to turn it off until I used the key to disarm it. I did use only 3 wires to hook it up. I noticed that you said to connect the alarm's brown wire to the (+ ) trigger. Could this be my mistake? I connected the brown wire to the (-) trigger on the siren. Were you able to pull up the install intructions on the alarm to see if I am using the correct output for the siren. Dude, I really appreciate all the help. Thanks for having patience.

The wire coming off of the APS-400 for the siren is a white with black trace on it. The siren is in fact a positive pulse from the alarm system.
Take what ever color wire from the back-up siren that is the *positive (+)* activating lead, and connect it to the APS's white with black strip.
You should be good to go from there. If you need more help, please ask.
P.S.
Please confirm the wire colors from the BB siren for us all, as I have read over this thread several times, and it was never stated as a fact, as to what it is.

There are 4 wires. Red and Black (+ & -), also Blue ( - trigger) and white ( + trigger) . I'll check it out hopefully tomorrow when I get off of work if my 16 month old son lets me. Thanks again for your help.

Well. I was finally able to tackle it this afternoon. Everything worked out perfectly. Thanks for all your help. You really know your sh#t! When I connected the 12v constant, I spliced it into the alarms 12v line just after the fuse. I thought that it would add a little protection. If I were to connect a pain generator siren, would I just use the (+,-) outputs for the alarms siren? Would I need anything else like a relay or something or is it just a straight forward 2 wire hookup?

To do it safely, so as it will perform consistently and reliably. You will add a standard SPDT relay of your choice.
Everyone uses a 30 amp relay in the field, I prefer to use a 40 amp relay. The only reason is that it allows the user / owner to have that extra margin of safety in terms of current capacity, if they so desired to add in a siren, horn, or mechanical raid style horn, which draw alot of current in cold weather.
The choice is up to you on that aspect.
You will add the relay of your choice as follows.
87 - Constant +12 VDC
86 - Chassis ground
85 - From alarms siren output trigger
30 - Connects to all the siren(s) you wish, within the current limit of the relay. ie 30-40 amp max.
I would also ask you to ensure all the siren(s), are fused seperately, along with the application of SS self tapping screws, with a star washer, and dielectric grease compound.
