Clifford Chirp

Hello peeps

my first post here, so hopefully someone will be able to help

My Clifford Concept 300uk every now and again decides it's going to stop chirping on arm and disarm

it seems to happen if I use *+Unlock to silently arm/disarm and also when I've done a long journey.

has anyone any experience of this or know how to fix it.

the alarm stays programmed to "loud chirp" but just makes no sound.

help appreciated

Richard

I previously had an Clifford alarnm that  had a built in feature that if you switch to full ignition but did no crank starter and then turn it off it would set the remove chirp for on alrm cycle, it was in the manual  something for discrreet parking at night etc ..

yeah, it's not that though, cos then the chirp would have re-instated next cycle but it doesn't

thank you

Richard

any ideas?

bttt please.
