104X12 Alarm Lock Electric Deadbolt 12VAC/DC Fail-Secure

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 "fail-safe" 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. 24AC/DC and 12VAC/DC models available.
