You can get CARBON key fob covers for toad, about £10, easy to swap bits over.
ALL alarms must be supplied in silent arm/disarm mode now, this is a EEC requirement due to noise pollution, but ALL toad can have the siren chirp on arm and disarm ENABLED, takes a few minutes but easy going through key positions with chart, that they DON'T supply, if wanted PM me your email and I'll send it to you.
There are 3 volume levels the lowest is about "normal" chirp volume, the loud IS loud and would piss your neighbours off in the early mornings!!
If getting one installed just ask installer to enable chirps, they wouldn't mind at all, but "officially" they haven't of course.
