autopage 315, dei 795t pager, 1996 240sx

My car info: 1996 Nissan 240sx
My Alarm unit: Autopage 315
My Pager unit: DEI 795T

I had an Autopage 2600 in my car when I bought it. It burnt out from not being installed correctly. It was hooked up to a DEI 795T pager unit. The pager unit was fine but when the shop installed my Autopage 315 they said they could only hook it up to the door trigger. IE, the pager only goes off when the door is opened.

I really would like it to be hooked up like the old one was, so that my pager goes off whenever the alarm is triggered, not just when the door is open. Can I do this? I don't see why not, I would just hook the brown wire from the pager unit to the siren + but it only pulses low voltage short pulses so it does not stay steady long enough to trigger the pager unit. Maybe I need some sort of relay?

Any help would be great, and if I posted to the wrong section/area please forgive me as this is my first post here and I am still getting my bearings around the forums.

So, no help? No ideas at all?

Any help would be great, I'm waiting patiently.

Thanks in advance!

your post is kinda vaugue, what exactly do you want to do with the siren and the pager, the alarm only goes off when the door is triggered, if so, you could probably wire your other contacts to the door input, you could also wire your sensors, but they would show up as a door being triggerd anyway, and not to mention full trigger and warn away would be the same on the pager if you did that. sound like the directon you're thinking off, if not, then explain a bit more in detail, and maybe then more advice might come your way, cheers.

-------------

Sorry for being vague, my first time here and am trying to learn more about what details I need to list. Don't want to mess up and post a lot of useless information if need not be.

I'll try to make it clearer. The alarm goes off from shock sensor or from the door being opened. I can get you the wiring diagrams for the pager unit, that at least shows the wiring diagram. I want the pager unit to trigger whenever the alarm sounds, not just when the door opens. I can offer any information that I have. I just don't know exactly what I need to do.

I'm not technical, I do OK with wiring. I just know that it used to work that way with the old alarm unit. I thought that both units being from autopage I could set it up the same way but have no clue as to where to begin.

Thank you again for responding, and please have patience with me as I am trying to learn how to use these forums.

I really hope that helps!

i'm not familiar with your specific unit, but if only the door trigger causes the pager to respond, them maybe you could wire in your shock sensor full trigger output to the door contact, the warn away would not be reported to the pager though

I'm trying to understand what I need to do. Thank you for the information, maybe this will be helpful, the link to the PDF install instructions for the DEI Pager unit. (it is a old unit)

I cannot find an online install guide for the Autopage 315, but I will keep looking.

The guy at the shop told me there was no way to hook up this or any other pager unit to the Autopage 315 in any other way than the door trigger for some reason they cannot explain... They charged me $320 for this unit (including installation) which is very high since they didn't tell me about the pager situation until it was already installed... I really think the guy is just trying to get me to buy a more expensive unit ($600+) and after I complained about just paying him over $300 he said he would knock off $100 for the old unit.

I'm just tired of getting ripped off and want to try to do it myself. At least I know I won't rip myself off.

And the door trigger to shock sensor trigger, that sounds perfect for what I want to do, just not sure exactly how it works.

well, i saw the diagram in the link you posted, anyways, does your unit have an off board shock sensor, the diagram made no mention? that's the only way this is gonna work. unless, you get help from someone like mr.idiot to make the connections inside the control module.

-------------

The pager unit itself does not have a off board shock sensor. The alarm unit itself (autopage 315) does however have one. I'm not sure which wires to try hooking up to which though. I don't want to ruin anything, but I am willing to try.

tell me what colour wires you have coming of the sensor, there should be about four wires,

red- twelve volts

black- ground

green- warn away

blue- full trigger

once you verify this we can move on.

-------------

Confirmed, Red Black Blue Green.

ok, now here's the thing, with this setup, both warn away and full trigger will cause the alarm to full trigger, showing up on the pager as a door tamper alert, that being said, using a single pole double throw relay, connect like this,

pin 30- ground

pin- 86 twelve volts,

pin 85- from the shock sensor diode isolate the green and blue wires with two one amp diodes, bars facing away from relay,

pin 87- to the door wire.

on a side note, the green wire is just warn away, if you would like the sensor to only report with full trigger, then just eliminate the green wire from pin 85 on the relay, and use the blue alone, no diodes needed.

it's eleven here, i'm out for the night, post up, i'll reply tommorow, good luck.

OK, I'm going to go pick up a relay today so I can try this out. I'm going to try and pick up some diodes too. If I can get the diodes I will try wiring it the way you said first, if I can't find diodes at the part store I'll do the second option. I don't care how the pager registers as long as the pager goes off whenever the alarm goes off I will be so amazingly happy!

Well that didn't work well at all. I went to auto parts stores, they looked at me like I was crazy when I said what I wanted... Said I needed a part number, so I realized that was a bad idea.

Then I went to two different car audio installation places that install alarms. They confirmed the original shop often tries to rip people off this way and that is how they get most of their business. They also did not know anything about autopage alarms so they told me they couldn't help. They also looked at the print out of the relay you described and told me they couldn't help me or sell me the relay, but could sell me a new alarm. (of course)

Do you know where I can get a relay like this? Everyone wants me to buy their alarm and not help with the one I have so far. I just figured there had to be a work around for it, and from what you describe there is.

That's the one! Thank you, I swear I looked on their site for the install manual but could only find the user manual. I was probably looking right at it again, thank you!

Hopefully that plus this: DEI 795t Pager Unit Install Guide will get something clear that I can do without much modification to get the pager to work as soon as the alarm sounds.

I'm feeling a bit more confident now.

This is too easy. Just connect the blue from the shock sensor to the blue zone 1 input of the 795t. Connect the green of the shock sensor to the gray zone 2 input of the 795t. The manual for the 795t clearly tells you how to do this. No diodes, relays, transistors or flex capacitors needed.

Thank you, if this works I will hook it up this way. No relay like stated previously? I can just tap into the wires and connect? Awesome!

I'll pick up some connectors today, and barring any flooding (a good chance) I'll hook it up and let you know how it went.

It's kinda hard to work on the wiring in a 1/4 foot of water, and man are the mosquitoes and fire ants angry!

mr jworm, he said that only the door trigger sets off the pager, which is why i recommended he use the relay and the diode connected to the door wire of the shock sensor trigger wires, since he wanted the pager to also page when the shock sensor was triggered although it would ahow up as a door trigger on the pager anyway, he mentioned that he just wanted it to work,

and mr tanshin if what j worm suggested does work, you have been giving me wrong info!

-------------

t&t, I don't believe he said that the shock sensor wires were ever connected to the pager unit wiring. That is the problem. He needs to connect those.

tanshin, if you have the siren wire connected to the pager unit you should disconnect it. It should only be connected when the alarm does not have a ground when armed wire. If it has not been connected already, the ground when armed wire needs to be connected to the pager unit. Also, you need to install a diode on the ground when armed wire that goes to the starter kill relay to prevent the ignition input from backfeeding to the pager, or else the pager will keep going off if the shock sensor is ""shaken" or a door is opened when the ignition is off and the alarm is off. That would be annoying.

You are correct, I don't care how it triggers or what it triggers as. I just want the pager to go off when the alarm sounds. Right now only the door trigger is hooked up. Everything I told you is correct to the best of my knowledge. I am learning as I go, just trying to not get ripped off again/more. If I have given any wrong info I apologize.

No, the shock sensor wires are not connected. No, I don't have the siren wire connected to the pager. I will try to connect it tomorrow as you have described, if the sensor keeps annoying me I will find someplace to buy a diode. Sound about right?

Like I said I am new to this and the guy at the parts store looked at me funny when I asked if they had any one amp diodes, said they don't have anything that doesn't have a part number... Made me want to slap myself on the head for even asking. I'm not sure if any of the radio shacks are even open in this town any more, I will do a google search in the morning.

Thank you both once more for all the help.

I hooked everything up like described and everything works wonderfully! Now I know they were trying to rip me off, and will never go back to that shop again. In fact I will try my best to learn as much as I can so I can do what I need to myself.

Thank you for the help, I feel my car is much safer now!

Exactly why I've NEVER taken my cars into shops to have electrical work done by other people. With a little study time, little electronics background, lots of reading forums and such and I've installed 2 bulldog systems (3yrs ago and I didn't know any better), replaced bulldog systems with DEI Viper 160xv, installed a 3rd 160xv and a python 1400xp(essentially a 160xv lol). Fixed a buddy's autopage RKE system and countless auto repairs from bad or old wiring. And all the mistakes I've made were cause of carelessness on my part. Forgetting about the parking lamp jumper or mixing up the starter wires, my only two mistakes.

I LOVE MY MULTIMETER!

here is what i just did on the work bench.
i used a 550esp viper and 795t and 2 508D units we will name them 508DA

and 508DB for reference.

on the 795t i used the orange GWA wire and not the siren input..
and i did not use any shock sensor at all.
i hooked 508DA to the shock sensor input and tapped 508DB's blue and

green wires each respectivly into 508DA's blue and green wires but

poweRED / grounded 508B from a source other than the shock sensor input.
then a tapped the blue wire from the 795t into the blue wires from the

pair of 508 sensors. NO DOIDES WERE USED DURING ANY OF THIS WHOLE TEST.

even though each 508D was only triggered enough to warn away, the pager

STILL went off. and of course went off also when either 508D went

"red".

then i removed 508DB's blue wire and the 795t's blue wire from the mix

and connected them to the regular multiplex wire on the 550esp main

harness.

the ONLY time the pager went off was when 508DB went"red".
the pager remained quiet through ALL warnaway and 508DA going red(which

still set off the alarm like a good boy).either 508D could warn away

and not trigger the pager.

THEN.... i took 508DA's blue wire and moved it from the shock sensor

input to the blue multiplex main wire with the 795t blue wire and the

508DB blue wire.
the system worked perfect. no warn aways triggered the pager and all

and "reds" triggered the pager right along with the alarm going off.

i hope this helps.

If your system moves you physically and not emotionally, you have wasted your money.

test number 2. check this out..
i connected both 508d sensors to the blue mpx wire except this time i used some diodes and

put each sensor on a different pager channel.
i tied the zone 1 wire from the 795t into 508dA and then through a diode and into the blue

mpx wire on the 550esp.
then i took 508dB and tied it to the zone 3 wire of the 795t and through a diode before

connecting it to the same blue mpx wire.
even though each sensor would report a different zone to the pager, they would also set off

the alarm reporting on the 550esp's zone 4.

my next test will be to use two 795t modules simultaniously and have one report as car A and one

report as car B to the same pager and see if i can monitor 6 different zones of paging from the same car while

i only have a few zones available on the 550esp.
