Adding a pager and tilt sensor

My car alarm is OEM BMW made by Alpine, it has a build in glass sensor,  i added Alpine 8327 shock sensor and now want to add a tilt sensor. Since evrything in this alarm is made by Alpine i want to have Alpine tilt sensor as well. Now the problem is that Alpine does no longer make alarms. What Alpine tilt sensor model is good for my case, how and where can i get one.

It will help me a lot if i know Alpine tilt sensor model numbers.

Can a 4 wire sensor be mounted on oem alarm that requires only 3 wires (power, groung and output)? This sensor has 4 wires:1-battery input, 2-ground, 3-sensor output, 4-sensor control. What sensor control does or can it just be ignored? I have a oem BMW alarm made by Alpine, it has a build in glass sensor. The tilt motion sensor i'm asking about is Alpine 8322 model that is an old item and it prevents car jacking-tilting, don't know much more about this. Anyone has more info on this?

I have computer upgrades going on right now but this is where I'm at with your question. I looked over the weekend and was unable to find a wiring diagram but I did bench check the older first generation style sensor.  Your's 'may" have the same wiring and I'm leaning towards it does as Alpine was pretty consistent with wiring codes.

The yellow wire is a constant 12V (0.01A current draw), black is chassis ground, gray is negative trigger output, and the gray with blue tracer is the solenoid set wire. The solenoid set wire gets a pulsed 12V input to it to set the sensor. The older Alpine system used one pulse on that wire to set the sensor and then a second pulse to fine tune the sensor levels setting so it was more level than after it was from the first pulse. I tested the sensor I had and this sensor does require the double pulse or a single pulse to set it. If the sensor dows not get the set pulse the sensor my be set on an angle that the car is not on and it may trigger from a slight tilt instead of a larger one. It's possible to hook the solenoid set wire to the parking light flash output but I would also add a diode inline.

If all else fails, wire yours up temporarily and see how it works and then try pulsing the solenoid trigger wire to see if it makes any difference in it's sensitivity.

Is there a way to test the functionality of  DEI 507M tilt sensor with a voltmeter, or other way before it is permanently mounted to my OEM BMW alarm. This sensor has 3 wires: +, - and sensor output.

Use a multimeter, ground the (-) of the 507M give the (+) 12v ground the (-) of the meter and put the (+) on the sensor output. You should be able to hear a beep when the sensor is tipped.

You might be able to use DC volts, it depends on how sensitive your multimeter is. You would be better off using the continuity function. It should have an icon that looks like a sound wave and when you touch the (+) and (-) together you should here a beep.

Yes, it did work, now i have to find more info or a web link in order to do a quality instal so my OEM alarm will have an extra feature.

I've used models similiar to the DEI 795T before in support vehicles at the drag strip so if the driver or someone was out on the track grounds we could activate the pager and they knew to come back to the trailer for something. The units used to have positive or negative triggers on them and the pager could be set to vibrate or make noise and it had 2 or 3 LED's on it to let you know if it was a door that got opened, the hood, or a sensor as well as a mode for pressing one of the dash control buttons with the kit. They used to go through the factory mast antenna systems like an FM modulator but the opposite way and they may have changed to their own stand alone antenna system.

My OEM alarm detects glass breakage and shock blows, what i need to add to this is: 1.Tilt detection  2.Pager or signal device that will tell me the alarm has been activated 3.Alarm siren sound delay for up to 1.5 minute so  I have some extra time to reach to the car location before siren even starts to sound. In other words i want to catch the person who activated the alarm. 

I would need more info on call guard features... think will go with adding DEI 795W or T, need to know what is the difference between the 795T and 795W. My OEM alarm has built in glass sensor and already added shock sensor, it performs very well. In addition to DEI 795 i want to add DEI 507M tilt sensor and DEI 528T pulse timer. Will i be able to delay the alarm siren activation with DEI 528T? I think this will take me some time to have a clear picture on how to do it and will depend how quickly the information will be provided to me from members on this board. 

It is all up to your will and time availability to provide me with info how to do this.

Adding a delay timer to the siren would work to allow it not to sound for a certain amount of time but does your system also flash the parking lights when tripped and would you want those also to be on a delay ?. If so I would think you could add a second timer or with one timer use either the parking light output or the siren output and then branched off out of the timer to both the siren and the parking lights so they both work.

Jim

You are right, the turn signal lights are activated as well, will it be safe to use one timer only, for lights and siren? I just found some info on another pager made by Alpine, it is 8205. Any feedback on this pager, can it be wired with my OEM BMW alarm (this alarm is made by Alpine too) is it any good compared to DEI ???

You could do it a couple of ways. First would be to use the siren output to the timer delay and then out of this to two relays with those being fused seperately so that should a parking light or something else in that circuit become shorted it would blow that fuse but the siren would work or visa/versa. The other option would be to use the parking light wire instead of the siren output wire.

Jim

I believe the siren and lights will signal for about 1 minute and if i do a 45 sec delay it will only soung for a short 15 sec... The idea of adding a switch(es) that will turn the siren and lights on-off is something i might go with. I am again confused on pager choices, i need a pager with a long range, my car is parked indoor and i am about 200 yards away and indoor as well. So is it DEI, Alpine or something else that will be the best for this. DEI claims up to 1 mile for 795 pager, some say: "Yep, I got one, installed it and its a waste of money. The thing only works 20ft away and triggers everything ur siren goes off (that means when you one and close the car). So I pretty much stopped using it and turned it off." I hear others talking good about Alpine pagers... need more info from this board on pager selection.

Well, i did install myself the OEM BMW alarm, it was pretty much plug'n'play since my car was pre wired. I took my time and it came very good. Also i added the Alpine shock sensor as the OEM alarm came with only build in glass break sensor. Now i have glass and shock protection. Want to add the toilt sensor and a long range pager as well. This might be a little more complicated. I still have to decide which pager to go with, there are not many long range that are compatible with OEM alarms. I don't want to install complete new aftermarket alarm just for having a pager, preffer just adding a pager to this OEM alarm which is made by Alpine for BMW. I have a DMM and wanted to confirm the right way to identify + and - triggers.

Want to wire DEI 795T pager to OEM BMW alarm which is made by Alpine for BMW. This alarm has bult in glass break sensor and I have added Aline shock sensor as well. DEI pager has 10 wires, it is clear how to wire some of them but the question is do i have to connect all 10 wires in order to make it work?

Red, black, orange will activate it.

Blue, gray, violet, green are you trigger inputs. Use as few or all if you need.

Use brown only if the security system doesn't have a "ground when armed" or negative starter kill output.

If your car has an electric or electronic antenna then connect the white wire to activate the latter when there is an alert sent by the pager.

Almost there...

(Red, black, orange will activate it.) 1. It will activate but it still does not make the pager to beep, right?

(Blue, gray, violet, green are you trigger inputs. Use as few or all if you need.)  2. I have to use 1 at least, right?

Use brown only if the security system doesn't have a "ground when armed" or negative starter kill output. 3. I will have to post the BMW alarm scetch, not sure if i have "ground when armed" or this is called with different name(s) as well.

(If your car has an electric or electronic antenna then connect the white wire to activate the latter when there is an alert sent by the pager.) All clear on this, i have no motorized antenna. But why there are 2 wires for this?

Dual radar sensor DEI 508D has 4 wires (red, black, green, blue), want to mount this and i think the center of the vehickle is a good location. I don't want to link this sensor with the alarm brain (no siren or lights when this sensor activates), it will be linked with the alarm pager DEi 795T only. My question is will this work that way and regrading green, blue wires that are triggers for inner and outer zones.

1.The inner zone wire will trigger (will give ground output) for 1 second - is this enought to activate the 795T pager?

2.The outer zone wire will trigger (will give ground output) for 1/2 second - is this enought to activate the 795T pager?

Your gonna HATE that thing...I promise. When the weather changes....so will the sensativity. Do you live in a part of the US that has all 4 seasons....it will be worse then. Your remote will be going off for NO reason. I do not know any of the particulars on the DEI peice, but I do know about a microwave sensor.....they suck.

Remeber folks.....just my opinion.

The car will be mostly indoors, will sensitivity change because of the exterior temperature?

Any other proximity sensor that you would recommend?

Need to diode isolate the sensors, where can i get 1N4001/L diodes? Do i have to mention other specs while ordering like ampere rating etc.?

OEM BMW alarm made by Alpine with built in glass sensor, have Alpine added shock sensor, now i need to add a pager DEI 795T and tilt sensor DEI 507M. The alarm does not have a "ground when armed" wire, how can this be resolved, think need the relay but need more instructions -what model, how to do the wiring in order to make a "ground when armed" wire.

If you have a real electronics store locally you can get them cheap.... they should be around a dime apiece.... The net is not hardly worth it because of shipping unless you need other parts.

At the Shack they cost substantially more.  Radio Shack has them but I hate going in there.  I have more than once gone to a local Stereo/ Alarm shop.  And asked the installer for some.... the last time I bought 5 of them for a buck.

It is an OEM factory BMW alarm made by Alpine, i need to have a ground when armed wire every time i arm the alarm and no ground when disarming the alarm.  The alarm harness plu has 12 pin connector, 2 of those pins are door lock + and door unlock +. Would this be the easyest way to create ground when armed from these 2 pins using relays. I believe both lock and unlock wires have a one time pulse + current. How can i do this.

The alarm (made by Alpine for BMW) has a built in glass sensor only, i added Alpine SEC-8327 shock sensor wiring the ground trigger to alarms hood pin switch, red 12V wire to alarm harness hot wire and ground to accessory so when the car is turned off the sesnor is on, did not diode isolate. Now i want to add some more features DEI 507M tilt sensor and DEI 795T pager and this is the reason I'm asking for ground when armed wire. Installing the 3 wire tilt sensor should not be to complicated for me but 795T pager is my nightmare as I'm not a pro. Basically i need to make the pager armed and disarmed at the same time with the alarm. I have the alarm diagram and pager diagram, need the info from this board...

This link shows the alarm diagram: https://forums.bimmerforums.com/forum/showthread.php?p=8317743#post8317743

Pins from 1-12:

1 hot at all times
2 ignition
3 chassis ground
4 driver's door trigger
5 passenger's door trigger
6 not used, rear door trigger
7 siren
8 parking lights
9 door lock
10 door unlock
11 trunk trigger
12 supervised dome lights

What would be simple and reliable way to arm and disarm  the pager simultaneosly with alarm?

1.The alarm has 2 separate pins, one for door lock and the other for door unlock, both are instant  (-) controled by remote. The TR-7 has one input wire for this, can I just tap on both door lock and door unlock pins and wire them to TR-7's input  and diode isolate so the signal does not pass from one pin to another?

2.Will TR-7 drain my car battery if the car is not used for 1-3 weeks? I found that TR-7 is about 150 m/amps. The reason I'm asking this is that there are more devices wired to the security system: alarm brain, led, shock sensor, tilt sensor, pager and two DEI 528T pulse timers
