ebike alarm 'standard' wiring

[alsmith]

I've been thinking about fitting an alarm on my bike. Several of the alarms I've seen show an alarm with a 2 pin plug (power), aerial, and a 4 pin connector with 3 wires. This appears to be some kind of standard fitting and the only information I can find is that it is
1 Brown: 'A3' Motor Phase
2 Orange: Vcc
3 Blue: Signal
Can anyone tell me what these connections are to? The Chinese suppliers just come back with stupid things like look harder for the plug, it must be there.
The wiring diagram was also useless when I got one- it just showed a box with exactly the same on it.

Best I've found are smallish jpg's of installation notes, but it's in Chinese (I think). Is this recognisable by anyone? I don't think it can be a microwave/ultrasonic type sensor because they have +, -, and signal.

if you open the page in chrome it will translate it for you.

It only has the text in a jpg, not typed on the page. I've found several 'different' sellers with exactly the same text and pictures.

Oh well, never mind. I just thought it might have been worth a try because it was such a low price.

I would change the topic to something to the effect of: "Help needed to translate chinese ebike alarm" ... Maybe one of our chinese members can help you out. Global forum FTW!

I have a couple colleagues and multiple graduate students from China that may be able to translate this for me, I will ask one of them tomorrow. I am kind of interested because I was thinking of installing an alarm on my e-bike build I am currently trying to finish, but was debating about just purchasing a car alarm and running it through a DC/DC converter to get the 12V. I may even have space left over on the enclosure to stick a couple Japanese type car horns to really give it the effect.

If I can get it translated I will post it here unless someone beats me to the punch.

I would like to know where you found these alarms?

Removed link..Hawk x 50 bike alarm

I have this one on my ebike.Works great with 4x18650/7812.

I've been looking at the Hawk, Spy LM100, and a cheaper one on aliexpress that has the features of the spy.
Most alarms seem to only have an impact sensor for when the bike is bumped or knocked, a few have a tilt sensor as well, and a couple have a microwave sensor either included or as an option. Is the impact sensor sufficient on its own? The microwave sensor can detect someone within a close distance to the bike but does this mean false alarms, or is it even necessary. I saw one claiming the sensor was not set off by rain where ultrasonics are. It makes me wonder if that is a hint that some are set off by rain?

I thought it might have been easier to get the right alarm.

And then I'm tempted by the 2 way alarms, so I'd know if the alarm does off. Most don't give a range but I contacted one and got the answer of about 20-30 metres. A bit pointless?
Then there are the SPY ones which claim 1000 metres, and 5000 metres. Just think, getting an alarm 5,000 metres away- that's over 3 miles- do you run back (taxi?) to find nothing there. Even 1,000 metres is over half a mile, but that seems more sensible.
But is a 2 way alarm really worth the bother? If the thief isn't scared off by the alarm sounding then the only thing stopping them are your locks and chains.

There's not an easy answer.

Hawk X50+3D tilt sensor+2 zones microvawe sensor+integrated tracker+Kryptonite U-lock.
Works fine for over a year.

That's quite a comprehensive setup!

Can you give your experience with the alarm, especially the microwave sensor? What kind of coverage have you set it for, is it affected by rain, hail, snow, how sensitive is it- anything you've learned please!

the extra meters range is for when there is several feet of concrete between you and the bike. eg most situations where i worry about it being grabbed. Does anyone here know of a good (cheap) high powered SIMPLE WIRELESS SWITCH. I can build my own alarm then!!

There are plenty of remote controlled switches out there with relay switched outputs on ebay and other places. I did consider this as a switching option but prefer an alarm with it.
There's quite a choice from 1 channel, 2, channel, 4 channel, latched, momentary, 2 channels linked so when one is on the other is off, and more channels, and varying ranges with varying remote sizes. So many options! Look through 'remote control switch' on ebay, fine tune to your needs.

just found this thread after posting some research on https://endless-sphere.com/forums/viewtopic.php?f=2&t=75887...

I have a controller-alarm combo that has a 5-wired interface, but the signals are the same...

basically, they are plugged on battery v+ and v-... once there, the wire of the circuit that gets closed when you press the lightning button (remote start) goes to ignition, one goes to controller motor lock, one comes from controller to tell alarm if the wheel is moving.
