We strongly encourage you to watch the ‘How To’ Video before installing your new device.
DISCLAIMER: Please note that if the provided instructions are not followed accurately and the door functionality isn't tested before being closed, our ability to provide additional assistance is restricted. An incorrectly wired safe door could result in your door not being able to open.
What you will need
What you've received
Battery Backup
Please note that the Override Key has now been replaced with a Backup Power Kit.
Power Back-Up Kit
Plug back-up kit into the power port at the back of the safe OR on the right side of the readers that are equipped with a port.
Step 1: Open the safe door and then power off the safe
Warning: Ensure to open the safe door BEFORE powering off the safe.
Important: Before starting the retrofit, put a screwdriver or similar object into the catch on the door. This will prevent you from accidentally locking yourself out of the safe while performing the retrofit.
Step 2: Identify your existing reader
Use the picture below to identify the model of reader that is currently on your safe. This will help you determine how to correctly wire in your new reader.
Step 3: Identify your existing reader
Our safes come in a variety of sizes. Using the pictures below, identify your safe.
Our 'M' Series safes are our smaller models
Our 'C' and 'S' series safes are our larger models. These models also require an ethernet cable to ensure the new reader can be connected to the existing safe network cabling.
Step 4: Remove Existing Reader
On the bottom of your existing reader, just below the keypad, there is a retaining screw. Use the Torx screwdriver (with the star-shaped end) that we have provided to loosen the screw.
Once the screw has been sufficiently-loosened, your existing reader can be lifted up and off its mounting bracket. Lift the reader gently, to avoid damaging any of the existing wiring.
Gently pull to remove the wiring connectors that are plugged into the back of your existing reader, and disconnect the Ethernet cable.
Step 5: Remove Internal Cover
For Model M Series Safes:
Using your Philips screwdriver, remove the two screws from the cover on the inside of the safe door. Carefully pull the existing wiring through to the inside of the safe door.
Once this is done, use your Phillips screwdriver and your pliers and remove the mounting plate that your old reader was attached to.
For Model C, CW & S Series Safes:
Using your Philips screwdriver, remove the seven screws (including back, right and left locations) from the cover on the inside of the safe door.
For SC403/US700 style readers, remove the black cable connected to the ethernet jack. Carefully pull the existing black wiring out through the wire hole leading to safe door.
Once this is done, use your Phillips screwdriver and your pliers and remove the mounting plate that your old reader was attached to.
For BioStation readers
The Ethernet Jack is connected directly to the back of the reader. The Ethernet cable from the back of the reader should already be disconnected from Step 4.
Shimmy the wire in through the wire hole - you will need this inside the cover panel to connect the upgraded Ethernet Jack provided with the new prebuilt reader.
Once this is done, use your Phillips screwdriver and your pliers and remove the mounting plate that your old reader was attached to.
Step 6: Attach Reader Wires
To install your new reader, you will be connecting five wires and one jumper wire. Our easy-to-use Tap Connectors allow you to connect the new reader wiring, without any cutting or splicing.
When connecting the wires, you can install the connectors by squeezing them onto the old wires by hand, or with a pair of pliers. Ensure that the connector click and lock into place. See below for an example.
Important: Please read the following instructions carefully, and note the colors of the wires that you are connecting. Please also make sure to connect the wires in the order shown.
ZKTeco SC403 and US700 with M-Series Safe Models
Using the supplied Tap Connectors, make the following connections:
1. Wire #1 (jumper wire) connect 2-Pin black wire → 10-Pin black wire
2. Wire #2 (blue) → red wire on the 10-Pin Connector
3.Wire #3 (black)→ black wire on the 2-Pin Connector
4. Wire #4 (white) → blue wire on the 10-Pin Connector
5. Wire #5 (green) → white wire on the 10-Pin Connector
6.Wire #6 (red) → red wire on the 2-Pin Connector
ZKTeco SC403 and US700 with C/CW/S Series Safe Models
Using the supplied Tap Connectors, make the following connections:
1. Wire #1 (jumper wire) connect 2-Pin black wire → 10-Pin black wire
2. Wire #2 (blue) → blue wire on the 10-Pin Connector
3.Wire #3 (black)→ black wire on the 2-Pin Connector
4. Wire #4 (white) → red wire on the 10-Pin Connector
5. Wire #5 (green) → white wire on the 10-Pin Connector
6.Wire #6 (red) → red wire on the 2-Pin Connector
Suprema BioStation 1 with All Safe Models
Using the supplied Tap Connectors, make the following connections:
1. Wire #1 (jumper wire) connect 5-Pin black wire → 6-Pin black wire
2. Wire #2 (blue) → blue wire on the 3-Pin Connector
3.Wire #3 (black)→ black wire on the 5-Pin Connector
4. Wire #4 (white) → white wire on the 3-Pin Connector
5. Wire #5 (green) → blue wire on the 6-Pin Connector
6.Wire #6 (red) → red wire on the 5-Pin Connector
Suprema BioStation 2 with All Safe Models
Using the supplied Tap Connectors, make the following connections:
1. Wire #1 (jumper wire) connect 2-Pin black wire → 4-Pin black wire
2. Wire #2 (blue) → blue wire on the 3-Pin Connector
3.Wire #3 (black)→ black wire on the 2-Pin Connector
4. Wire #4 (white) → white wire on the 3-Pin Connector
5. Wire #5 (green) → yellow wire on the 4-Pin Connector
6.Wire #6 (red) → red wire on the 2-Pin Connector
Note: if your safe (M-Series Only) has an electrical key override feature, the jumper wire is not needed and can be left detached from the wires
Replace resistor
Note: this step is only required for C/CW/S-Series Safes.
The existing Resistor (brown) needs to be replaced with an upgraded Resistor.
Caution: The old resistor may be hot to touch! Wait a few minutes after powering down your safe and proceed once cooled.
A) Before unscrewing the existing Resistor, as a precautionary step, it is important to mark the terminals that the Resistor is connected to with a marker.
B) After marking the terminals, use a flat-head screwdriver to unscrew the Resistor from the panel.
C) Place the new Resistor into the marked terminal and screw them in.
D) Take the strip of velcro and place it to prevent the Resistor from touching the plate - it needs to be positioned in a way so that it will not touch any of the wires.
Step 7: Attach Ethernet Cable
C/CW/S-Series safes have an Ethernet Jack inside them, whereas M-Series safes have an Ethernet Cable.
For the C/CW/S-Series safes, you will need to plug in the supplied Ethernet Cable to the Ethernet Jack. (See Page 6 to locate the Ethernet Jack)
Then for All Safes, plug the Ethernet cable into the supplied connector, to join it with the new Ethernet cable.
Step 8: Secure the New Reader
Caution: Use M3X12mm screws to mount. Do not use bolts longer than those supplied to avoid damaging the reader.
Using the supplied Hex Wrench and the four supplied mounting bolts, attach your new reader to the door of the safe. Watch to ensure you do not pinch any cables.
Step 9: Replace Internal Cover
Note: Ensure that all wires are secured together with a zip tie.
Reposition the cover on the inside of the safe door, while watching to ensure that you do not pinch any cables.
Using your Phillips screwdriver, tighten the two screws.
Step 10: Testing
Reconnect the power to your safe. Note the following:
- The LED lights on the card reader and keypad should light up. If they do not, double-check the connections on Wire #3 (black) and Wire #6 (red).
- The buzzer should sound. This indicates that the door is open. If it does not, double-check the connections on Wire #5 (green) and both ends of Wire #1 (black jumper wire).
- Tap the supplied access card onto the reader. The latch should unlock. If it does not, double-check the connection on Wire #2 (blue) and Wire #4 (white).
- Close the safe door. The buzzer should stop. If it does not, double-check the connections on Wire #5 (green) and both ends of Wire #1 (black jumper wire).
- If upon start up the screen shows “initializing keys” - reboot the safe.
Light Indicators
There is a small indicator light capability integrated directly above the PIN pad on your safe door. There are a variety of colors that communicate different conditions detailed below.
