Alarm Lock 103 24v AC/DC Fail-Safe. From the manufacturer: Models 103 & 104RA are compact electric locks simple to install on all types of doors. The door is locked or unlocked by remote switch, key switch, time programmer or other electrical contact which interrupts the power. Model 103 is our standard failsafe unit which projects the bolt only while power is on. When the power is off the bolt retracts. Model 104RA (reverse action) unlike our standard unit is `fail-secure` and will project the bolt only when the power is `off`. When the power is on the bolt retracts.
