Full Product Description The dormakaba Simplex 7104 Mechanical Pushbutton Lock provides battery-free combination access with an automatically relocking deadlocking latch. Authorized users enter the programmed combination and rotate the exterior thumbturn to retract the latch. When the door closes, the spring-loaded latch automatically engages the strike and returns the opening to secured operation. Unlike the Simplex 7102 and 7108 deadbolt models, the 7104 does not have to be manually relocked after each use. Its automatic relocking function makes it a better choice for employee entrances, utility rooms, storerooms and other controlled openings that should remain secured without requiring someone to extend a deadbolt manually. The 7104 features a 1/2" throw deadlocking latch with an adjustable 2-3/8" to 2-3/4" backset. This adjustable latch accommodates the two most common backset measurements without requiring separate 7102- and 7108-style deadbolt models. From the interior, the thumbturn retracts the latch without requiring the combination, providing unrestricted egress. Once the interior thumbturn is released and the door closes, the latch automatically returns to the secured position. Because the Simplex 7104 is completely mechanical, it requires no batteries, electricity, wiring, access cards, software, computer or network connection. It continues operating during power and network outages while eliminating recurring battery-replacement and electronic maintenance expenses. The lock stores one shared mechanical access combination. The combination can use one or more of the five pushbuttons pressed individually or simultaneously, providing thousands of possible combinations. Authorized personnel can change the combination from the interior without removing the complete lock from the door. Heavy-duty construction includes an all-metal cast exterior housing, vandal-resistant solid-metal pushbuttons and a force-resistant, clutch-protected exterior thumbturn. The clutch helps protect the lock’s internal mechanism if someone attempts to force the exterior thumbturn without entering the correct combination. The Simplex 7104 installs on wood or metal doors from 1-3/8" through 2-1/4" thick, requires a minimum 4" stile and is field reversible for left- or right-hand doors. Its weather-resistant construction makes it suitable for appropriate indoor or outdoor applications.

Function Summary Exterior combination required: Yes Interior combination required: No Interior free operation: Yes Automatic relocking: Yes Manual deadbolt relocking: No Key override: No Latch holdback: No Number of codes: One Power required: None Automatic Relocking The Simplex 7104 automatically returns the opening to secured operation each time the door closes. This is the major functional difference between the 7104 and the 7102/7108 deadbolt models: The 7104 uses a spring-loaded latch. The latch retracts when the correct combination is entered. The latch projects again when the operating thumbturn is released. Closing the door causes the latch to engage the strike automatically. No one has to manually extend a deadbolt. The 7104 does not include latch holdback. Choose the Simplex 7106 if a surface-mounted rim latch with holdback is required. Deadlocking Latch Protection The 7104 uses a deadlocking latch rather than an ordinary spring latch. When the door is properly closed and the auxiliary deadlocking feature contacts the strike, the main latch is protected against being forced back with a card or similar object. Proper strike alignment is essential for the deadlocking feature to function correctly. Adjustable Backset The Simplex 7104 latch adjusts between: 2-3/8" backset 2-3/4" backset Backset is measured from the edge of the door to the centerline of the lock. The adjustable latch allows one 7104 model to fit either common preparation. Set the latch to the correct backset before installation.
