Frequently Asked Questions - C800 Dormakaba

What is the difference between EU and EL functions?

EU (Electrically Unlocked, Fail Secure): Lock unlocks when power is applied; remains locked when power is removed. EL (Electrically Locked, Fail Safe): Lock locks when power is applied; remains unlocked when power is removed.

What is the RX function?

RX (Request to Exit) uses a microswitch that activates when the inside lever is rotated, signaling security systems for immediate egress.

What power supply is required?

A 24V AC/DC power supply with ±10% tolerance and at least 0.145A capacity. All solenoids are continuous duty.

How do I wire the RX switch?

Use the 3-wire harness: white (COM) and gray for normally closed, or white and purple for normally open. Connect with 22 AWG wire.

What wire gauge should I use for field connections?

Use 22 AWG wire for terminating lock wires to the wire transfer hinge. Proper crimp splices or wire nuts are recommended.

What door preparation is needed?

Machine a 3/8" wire raceway, a 2 1/8" cylinder lock pocket, and prep for a wire transfer hinge. For EU/EL use 3/8" raceway; for RX use 3/4" raceway.

How deep should the raceway be for the rectifier module?

Provide a 5/8" diameter hole extending 6" to 8" from the back edge of the cylinder lock pocket.

Can I use this lock on any door thickness?

Check door thickness before drilling. The template shows hole positions relative to the bevel edge. Ensure proper backset (2 3/4" or 2 3/8").

What does 'Fail Secure' mean?

Fail Secure (EU) means the lock remains locked when power is lost, securing the door. It unlocks only when power is applied.

What should I do if the lock doesn't operate?

Verify power supply (24V AC/DC), check wire connections, ensure rectifier module is not removed (warranty void if removed), and confirm proper switch wiring for RX functions.

USER MANUAL C800 Dormakaba

C800 ELECTRIFIED CYLINDRICAL LOCK INSTALLATION INSTRUCTIONS

1. Function Description:

EU - Electrically Unlocked (Fail Secure):

When power is applied the outside trim will unlock. With power removed the outside trim is locked.

EL - Electrically Locked (Fail Safe):

When power is applied the outside trim will lock. With power removed the outside trim is unlocked.

RX - Request to Exit:

A microswitch attached to the chassis is activated when the inside lever is rotated. The switch signals the use of the lever to security systems allowing a non-disruptive means of immediate egress.

NOTE: All installations should be in accordance with local electrical codes.

4. Installation Instructions:

A. Door Preparation

a. The door must be machined with a 3/8" wire raceway, Cyl. lock pocket & prepped for a wire transfer hinge. Make sure the pocket is free of debris.
b. Provide a 5/8" dia. hole extending 6" to 8" in depth from back edge of Cyl. lock pocket. This provide room for insertion of rectifier module and wires.
c. Provide a 3/8" dia. through hole for electrified functions or provide a 3/4" dia. for RX functions.

B. Install Wire Route

a. Run the wires from the wire transfer hinge through the 3/8" raceway starting at the wire transfer hinge & exiting into the Cyl. lock pocket.
b. Screw the wire transfer hinge to the door (at this time DO NOT connect the hinge wires on the jamb side to the wires coming from the power supply).

C. Install Outside Trim

a. Electrified Functions:

Terminate the two blue wires from lock to the wire transfer hinge device using 22AWG wire. Use proper crimp splices or wire nuts for terminating connections. (No Polarity of wire is required)

b. RX Functions:

Terminate the three wires from lock to the wire transfer hinge device using 22AWG wire. Use proper crimp splices or wire nuts for terminating connections.

c. Carefully slip the connected Cyl. lock chassis into the pocket paying close attention not to pinch any wires.

D. Follow UP

a. Mount the Cyl. lock per manufacturer's instructions.
b. Connect the wires from the power supply at the wire transfer hinge on the jamb side. Connect the wire transfer hinge to the jamb.
