Alarm possibilities

[knutk]

As an alarm I don't think the BMW alarm is better or worse than any 3 part quality system.

I do however find it quite convenient to be able to use the FOB for activating/deactivating the alarm. The OEM alarm also shuts down before the battery (at 12Ah only) is drained too much, and quite handy to have it integrated to the CANbus, using the bikes lights for visual signaling, and the alarm will be disabled when turning the ignition on. With keyless ignition you may program the alarm to automatic activation (a tedious procedure). When on a trip, the alarm activates automatically, and when you approach the bike for loading again you just turn the ignition on and off, and the alarm is deactivated long enough for you to load the bike with luggage.

The OEM alarm does not have the ultrasonic proximity sensor. What will a proximity sensor do to battery drainage. Will it be a factor to consider?

do you have the model? or a link?

This is the one I fitted: https://www.ebay.co.uk/itm/SPY-ALL-...+MOTORBIKE&_from=R40&rt=nc&_trksid=m570.l1313

I liked the fact that the main unit contains a backup battery and also the siren so it can't be so easily disabled as those without battery backup and with a separate siren which could have its wire cut. The optional microwave proximity sensor is a little difficult to setup as placement and sensitivity setting is quite critical. In the end I put mine in a position where it goes off if you stand in the position you would take to get on the bike. The first time movement or proximity sensor are triggered it gives a couple of warning chirps, then if disturbed again it goes into full ear splitting alarm mode. I don't get any excessive battery drain.

However I fully understand that this is not going to stop the bike being taken, but together with my other security measures (2 disk locks + chain and lock) I hope it would put off the scrotes. In the worst case I also have a BikeTrac fitted which improves the chances of recovery.
