Hey guys, I have a python 1000esp and I just received my backup battery in the mail. First of all, does the backup go in the car or in the engine bay? Second, it has 4 wires: power, ground, and a (+) and (-) inputs to the alarm. What are these inputs? I have the wiring diagrams for the alarm but i dont know what these are. Also, does the power to the main alarm stay connected to the battery post? What happens if you cut the wire to both the backup and main alarm, does it still go off? Thanks a lot

 

Thanks for the help Teken. Can you clear some things up for me? Im looking at the backup battery and it has the wiring diagram on it for the 4 wires, but it doesnt have anything about a backup siren. I have 2 sirens that I would like to use, but im not sure of how to connect these with a relay so that the siren goes off when the regular alarm goes off, but then stays on if both power wires are cut.

Also, about the (+) and (-) inputs. In confused about what they mean in the first place. Does the (+) mean that power is sent to this wire when the alarm is tripped, like power being sent to the original siren (wire H1/10 Brown (+) siren output)? Then for the (-) input, does this mean a ground is sent when this area is tripped, like with the doors? Im reading the manual for the original alarm and it says:

"Most vehicles use a negative door trigger circuits. Connect the green wire to a wire which shows ground when any door is opened. In vehicles with factory delays on the domelight circuit, there is usually a wire that is unaffected by the delay circuitry" H1/5 Greed (-) door trigger input.

So on the regular alarm, when a door is opened, a ground is sent to the brain and the siren goes off? Is this what I want?

Im just trying to understand everything first. There are (+) and (-) inputs and outputs......????!??!??!?!??

Finally, the backup battery was sent with this small clear box with 4 wires coming from it. These wires are really short, maybe 2', do I have to lengthen these, or are there supposed to be wires nearby that im supposed to utilize?

Thanks, and I apologize for the long post and "stupid" questions. However, these are questions that I dont understand.

What I have is the python 1000 esp, and a Backup battery, and two extra pieze sirens. What I want is for the backup battery to provide power to the alarm and siren in the even that the main power to the alarm is cut. I would also like to make good use of the extra sirens if possible. Im just trying to find out where everything connects, whats (+), whats (-), etc. So all im wondering is how everything is connected so that I can fully understand this to modify it if I have to. Right now, I just need to know how the backup battery provides power to the alarm through the Alarm (+) power input, and the Alarm (-) trigger input. Those are the two wires. Also, im sorry but I dont understand what you mean by the service port. How is this created?

Im reading on the battery now, that the Grey wire(Alarm (+) power input) says "GREY: To alarm power input (power output to alarm power input). so does this mean that the power to the alarm ONLY comes from the backup battery, and that the original connection from the battery post now goes to this grey wire?

Also, the Blue wire, it says "To alarm instant trigger circuit. Will trigger when batter is disconnected." Can this be something like the hood pin? What is this?

"DO NOT connect vehicles (+) 12V to alarm, use only the GREY wire of 520T."

I was just thinking, is it possible to use the (-) input from the backup battery and hook it up to a siren? It says that the wire will trigger when the battery is disconnected. Does the negative mean that it will provide a negative signal when the power is gone? Is it possible to hook the power of a siren to the battery, or some power souce, and this wire from the backup to the ground of the siren? Will it work like that, or am I way off? (still trying to understand this, sorry for my incompetence)

I apologize again for so many simple questions.

Thanks

Can you tell me how this is done? I thought that all you do is connect the 4 wires, and if the power is cut, than the only source of power for the alarm is the backup battery. How is this done?

 

Take the black wire and ground it to a solid chassis with a star washer.
Take the blue wire and hook it to the blue wire on the main harness of the alarm. If you have somwthing else hooked to the blue wire currently, you will have to splice these together with diodes, band side of the diode facing away from the alarm.
Take the red wire coming from the alarm's main harness which runs to the battery. Cut it. Hook your red wire from the backup battery to the side of your cut wire facing away from the alarm. Take the gray wire that is left and hook it to the red wire that is left, coming out of the brain. You may also what to hook in a connector so you may charge the backup battery if need be.

This is assuming that you have a DEI 520T backup battery. IF you have another manufacturer, these colors are likely not the same.

 

Hey, I just installed the backup battery and the old dei pager. Is the backup battery supposed to trigger the alarm when it is cut? I tried that and it didnt set it off. When I set off the alarm with the hoodpin, and disconnect the backup battery power, it goes from the regular siren sound to this mutated sound (barely hear). Whats going on? I used the 1 amp diode and connected the blue wire to the hood pin wire.

I thought the backup was supposed to trigger the alarm when it is cut....hmmm....anyone know? Also with the pager, do you only get paged when the 3 triggers are tripped? Meaning the door, hood pin, and trunk? So what if someone hits the car or breaks the glass, does it not page you since you didnt connect it even though the alarm is going crazy?

Note: the only other thing i have connected to the hood pin wire is the pager which i did not use a diode because i thought it was just an input to the pager and not a sensor that sends signals to the main alarm. Thanks
