HELP - ALARM knackered! (reply to this one)

[theweeninjaguy]

ok guy's i got my S2 elise serviced yesterday at jude performance who confirmed that the alarm siren is knackered as i kinda suspected due to there being no noise when the alarm goes off (just flashing indicators and an imobilised elise).

now Dan had told me how to get into the siren to replace it which i attempted today - unsucessfully cos the siren isn't where we expected it to be. i removed the wheel arch lining from the front passengers side and although i managed to find a couple of fuse boxes and the horn i didn't see any sign of the alarm siren!

so here's my question - how can i fit the replacement siren? can anyone tell me either there the existing non functioning siren is? or alternatively which wires to splice into to power the new siren? i spent about an hour with an ampmeter trying to find the right wires but again was left thoroughly pi55ed off and my car still doesn't have an alarm which makes an noise. so any help would be very much appreciated cos i'm at my wits end now

many thanks

there is a fuse for the siren in the fuse box n/s cover .
i assume you have an identical siren to replace the dead one ?
if you do it will be a case of making three connections 12v- earth- data wire ( coded link wire cont by alarm ) some times they are just a neg trip , but because the one fitted to the lotus is a cat 1 it prob will not .

when you start make sure that none of the wires touch !

If you're still looking for the siren, on the 111R it's located in the hollow underside area of the front crash structure... try this.

Romove the front undertray, it's bolted to the side wall part of the crash structure just in front of the ARB on the passenger side.

I have a spare siren from a 111R don't know if it's the same as yours tho

actually i bought a siren out of maplins!

so where are the wires i need to splice into? where's the actual alarm unit hiding?

Up in the passenger footwell iirc. Crawl in and have a look. After that, and once you are done, might I suggest:

it's not in the passengers footwell under the dash - i tried that yesterday and yes it was very awkward to get into.

it's a small car so i'm struggling to figure out where it could be hiding tbh.

you cant put any siren on there as the cont is via a data bus wire , this wire controls the siren . The two other wires will be 12v and earth . The maplin siren will have a 12 supply and will have a neg switched to it to sound .
