had the dreaded alarm siren failure by corroded batteries etc. Fitted a new second hand unit today and still hazards flash but no sound. Scanned with vcds lite and get...
01134 alarm horn h12 29.00 short to ground.
soon as I clear it then it returns.
Im not actually sure it's a fault of if the rechargeable cells inside have to charge up first before I will hear any sound. Does anyone know ?
