Disconnecting Battery, Alarm Goes Off!

[Slats]

Hey all,

Just trying to do a few things with my car which requires disconnecting the batter leads to the car battery.

The unit has a digital back up battery which of course sets of the siren as soon as i disconnect the battery leads.

This nearly made me go deaf when i first disconnect the leads!

My question is, how can i disconnect the leads without the bloody siren going off? Is it as simple as disarming the alarm and then do the work? I'm pretty sure the car was disarmed when i disconnected the leads yet the sirens till went off.

Thanks.

Someone answered this for me a while ago. It's obvious to me now, but I didn't think of it at the time.

You should have a key for the siren, usually mounted in the enginebay. The key turns the siren off so you can disconnect the battery. It's a tamper-proof feature of the alarm. =-]

You said a digital backup - they don't normally have the keys, right? I thought it was only analog alarms that had the key under the bonnet?

Yeah digital backup battery, no key.

maybe I should be patient and give the manufacturer a call tomorrow!~ hehehe But I'm sure it can;t be somethign too hard.

After disarming the alarm the siren should not sound when the battery is disconnected if it is digital, if it does then contact the manufacterer.
