[QUOTE="Steerpike, post: 758387, member: 807"] I have two of these CISA locks, specifically chosen for their strength. They have a 12V coil, BUT it cannot stand 12v continously, or it will burn out - not sure of the time period. It happened to one of mine when the control circuit got stuck. Now I pipe the CISA release signal through a 10,000uF capacitor to give it a pulse, but no continuous DC if a fault occurs. The coils are obtainable as a spare part. The will work as low as 9V.
