Before Installation
Read all instructions prior to installation.
1. Prior to beginning installation, cut off all power to prevent personal
injury and damage to S900 and peripheral equipment.
2. Connect the ground wire first, in order to prevent electro-static damage
to the S900.
3. Connect power supply to the S900 last. If the S900 does not operate
properly, always cut off power to it before examining/dismantling. Be
advised that wiring the S900 while power is on may cause damage to the
device. Possible resulting damage from not powering off the S900
prior to wiring is not covered by manufacturer’s warranty.
4. Mount the S900 at a comfortable height, typically between 4 and 5 feet from
the ground.
5. After installation, remove protective film from the S900 display and
fingerprint sensor.
6. To prevent being accidentally locked out while testing the exit-door
button, keep a person on the inside of the door.
7. Run the auto-test function to confirm that installation is successful.
8. In order to maximize the life of the S900, use the auto-sleep and wake up
functions.
9. We recommend using a 12V DC 1.5Amp power supply for proper
functioning of the S900 terminal. If the incorrect voltage is used, the
S900 may keep rebooting or may not operate the electric door lock (if
attached).

10. Improper wiring may cause the S900’s main circuit board and fingerprint
sensor to burn out. Resulting damage from
improper wiring is not covered under manufacturer’s warranty.
11. Only use supplied transformer and cord. Do not attempt extending the
cord by cutting and splicing.
12. If using RS485 mode of communication, use only a ZK
Software-supplied RS485 converters. Using a 3rd party RS485
converter may or may not work. If the RS485 cable length exceeds 200
feet, we recommend using a 120Ώterminator.
13. Refer to the user handbook and operating instructions for further
information.

2.Installation
2.1 S900 Wall Mounting
1. Separate mounting plate from the S900 by removing the screw at
the bottom edge of the S900. Special screwdriver is supplied.
2. Determine the position of the mounting plate on the wall. The S900
should be mounted on the external wall of the door approximately 4
to 5 feet from the ground. After the desired position is determined,
cut out an opening (approximately 1 ½ inch x 1 ½ inch) for cables
(see below figure’s shadowed area).
3. Line up the opening of the mounting plate with the newly cut-out
opening on the wall, and then screw the plate to the wall.
4. After installation, make sure the mounting plate is tightly secured to
the wall.

2.2.1 Door sensor connection
The door sensor is used to detect the door status (open or closed). The
S900 can monitor unauthorized entry and trigger an alarm if the door
has been opened by an unauthorized user or if the door remains open too
long.
- 9 -
2.2.2 Exit-button connection
Install exit button approximately 4 to 5 feet from the ground. Make sure
that the exit-button is properly connected to the corresponding terminals
on the back of the S900. (Unused exposed end of cable should be cut off
and wrapped with insulating tape.) Be sure no electromagnetic
disturbance occurs as a result of the installation.
2.2.3 Alarm connection
The S900 can trigger alarms and monitoring systems (only supports 12V
DC buzzers).

2.2.4 Door lock connection
Door lock connections depend upon the type of lock used (i.e. electric
door strike or mag lock) and surrounding mounting surface (i.e. wood,
sheetrock, cement, glass, etc.).
Be sure to distinguish between the positive and negative terminals on
both the S900 and the door lock. The unused bare end of the wire should
be cut off and wrapped in insulating tape. Note that the time-delay of the
door locks is usually adjustable.
Selecting door lock
For glass doors which swing both in and out, we recommend the use of
electro-magnetic door locks (aka “mag locks”).
For 1-way opening non-glass doors we recommend the use of electric
door strikes, instead.
While both locks are equally secure, the mag lock is considered safer
than the electric strike, especially during power interruptions. During a
power failure caused by fire or other safety threats, the mag lock will
“fail open” and allow people to exit a room/building unhampered.
Conversely, the electric strike “fails closed”. In the event of a power
failure, it is possible to exit a door secured by an electric door strike
provided there is a mechanical device (i.e. door handle or exit bar) to
free the door during power interruptions. ZK Software is not
responsible for any personal injury or damage caused by power
failure.

Connecting Door Lock
Although the S900 can supply power directly to a door lock, it is
recommended that the door lock be provided with an independent
power source in certain situations.
Provide an independent power source to the door lock if:
1) the door lock voltage is not 12V DC;
2) the door lock runs on 12V DC, but requires more than 1.5A current;
-or-
3) the distance between the S900 and door lock is greater than 15 feet.

Test and examine after installation

Enroll a fingerprint, and use that same fingerprint to test
access control system and door strike.

2.2.5 Ethernet connection
The S900 can connect via Ethernet by 2 different methods;
1) The S900 can connect directly with a PC by a using a cross-over
cable
- 16 -
2）The S900 can connect indirectly with a networked PC by wiring the
S900 directly to a network switch or router
3) RJ45 plug wiring diagrams for Ethernet

3b) Ethernet 10/100Base—T Crossover Cable
Most often applies to a switch or router，or directly connects
two Ethernet terminals (not through switch), fully supports
10Base-T and 100Base-TX.
