GateKeeper Overview
The GateKeeper h5 contains both the GateKeeper computer and relay unit required to operate the
door locks that work with the GymMaster software. The GateKeeper needs to be powered AND
connected to the Internet to work correctly. The GateKeeper can also be used to operate desktop
readers and receipt printers, which connect to the USB ports.
We strongly recommend that you use an Uninterruptible Power Supply (UPS) with line smoothing
to provide a constant power supply to the GateKeeper, Door Readers, Door Lock, Internet router
and any network components. The GateKeeper has an Offline Mode that will allow access to
current members during a network disconnection. Desktop PCs and other computer devices are
high power-drain, and should not be connected to the UPS. The UPS will assist in maintaining
normal member access and system operation in the event of a power failure or fluctuations.
You will need to check your own local and regional legal requirements for emergency entrance and
exit. It is strongly recommended that you install an Emergency Exit Button and/or a general Exit
Button for members in your door setup, and that you have alternative and separate key-lock
access or similar. Ensure that egress is possible in the event of an emergency.

Power Supply
The GateKeeper requires a 12V power supply capable of at least 2A. The GateKeeper is calibrated
to work with input voltage from 9V to 12V. Do NOT use a power supply with voltage greater than
12V or current lower than 2A.
It is strongly recommended to use a battery backup like an Uninterruptible Power Supply (UPS)
to maintain constant power for the GateKeeper, Door Readers, Door Lock, Internet router and any
network components. You can purchase a UPS that will allow you to plug in the router power
supply, door lock power supply and GateKeeper power supply directly.

Important Warnings
The Door Lock MUST have its own separate power supply. Do NOT use the
GateKeeper or the GateKeeper power supply to power any mag locks or door strike.
The Door Reader MUST NOT be mounted on conductive metal without an earth, or this
may cause interference issues. These issues are usually not immediately apparent but
will occur over time, preventing member access. You can install an insulating casing or
mounting to prevent these issues if grounding or alternative surfaces are not available.
Maximum length of a standard USB cable connection is 3 metres (10 feet). Do not use
multi-hubs or extensions to connect the desktop reader to the GateKeeper. For Door
Readers, ensure that the stub wiring is kept for future troubleshooting.
Install the GateKeeper where it can be easily accessed by gym staff. Staff may need to access it in
the event of a failure to power cycle it. If multiple GateKeepers are installed, mark which
GateKeeper is controlling which door readers to enable troubleshooting.
Fail-secure wiring installation can trap members in the building in the event of a power
outage if the UPS fails. Fail-safe wiring installation is recommended. Fail-safe wiring can leave the
building unsecured in the event of a power outage if no UPS is used.

GateKeeper Interface
Relay Terminals
These terminals are for signalling the door lock. For loads over 2A, we do not connect directly. Use
a secondary relay as a buffer instead.
NO Relay normally-open contact
COM Relay common terminal
NC Relay normally-closed contact
As door lock devices are often inductive, switching off the current can cause a voltage spike on the
wires to the door lock, damaging the reader. A snubber should be fitted near any switch or relay
contacts, for DC circuits a silicon rectifier diode such as IN4001 (supplied) is well suited. Please
note that the diode must be wired according to the diagram. The wrong polarity will cause a short
circuit, and damage the power supply.
The diode MUST be wired correctly according to the diagram, otherwise there may be
cumulative electrical damage to the GateKeeper board, the reader unit, or the device
power supply.

Exit Button Terminals
The GateKeeper expects a low level voltage trigger signal in the REX (Request to Exit) terminal to
activate the relay to open the door. You can wire a normally-open push button (2 terminals) to
Sensor and GND on the Door 1 or Door 2 socket, refer to the sample wiring diagram.
RFID Reader Sockets
The rear of the GateKeeper has two sockets. Up to 2 door readers can be connected. Each reader
socket has 4 terminals for reader, namely Serial A, Serial B, +12V OUT, GND.
The RFID reader has a number of wires, but only 4 of them are used. The unused wires should be
insulated from the rest. The 4 wires that are used are coloured green, white, red and black. The
default connection relationships between the reader terminals and readers are:
Terminal
Wire Colour
B (RX)
Green
A (TX)
White
GND
Black
VCC
Red
The RFID reader must be mounted in a location where the electrical noise is quiet. If there is a lot
of electrical noise, read performance will be reduced. Electrical noise can be generated from
sources such as other readers, motors, VSD’s, switch mode power supplies, CRT monitors,
fluorescent lights etc. New electrical equipment (if installed correctly) is usually ok, as it should
already meet EMC requirements.
If you have two door readers, they should be physically separated by a minimum of 5 cm, or 2
inches, to avoid interfering with each other.

Network Port
The GateKeeper requires an Internet connection via the Network port to function normally. You will
need a Network cable (not supplied), one end connected to the Network port on the GateKeeper,
the other end connected to a Network port on the router or a switch. Please ensure non-firewalled
Internet access for this connection. If you have an IT team that looks after the network you may
need to ask them to whitelist the GateKeeper. If the GateKeeper does not have a working
connection to the network it will not boot.
The GateKeeper can operate for short periods in Offline Mode during a network outage, as long as
the GateKeeper, door lock components, and facility network components have electrical power. It
is strongly recommended to use an Uninterruptible Power Supply (UPS) to maintain constant
power for the GateKeeper, door readers, Internet router and all network components, and to keep
your business secure in the event of a power outage.
The GateKeeper network port has a green/amber LED at the top left corner, and an amber LED at
the top right corner. The left LED shows whether the cable is correctly inserted. The right LED
shows network activity. When powered and connected to the router, you would normally expect to
see a solid left LED and a flickering right LED, indicating correct connection and ongoing activity.
USB Ports
Desktop readers and receipt printers are connected by USB cable to one of the USB ports at the front
of the GateKeeper.
The Gatekeeper USB ports MUST be used ONLY for GymMaster devices. If you
attempt to connect or charge any electronic device, such as mobile phone, digital
camera, etc, this can cause reader faults.

Sample Wiring Diagrams
These wiring diagrams are intended only as examples of how the relay unit and RFID device may
be installed. Actual installation wiring may differ. The GateKeeper is supplied with short wiring so
that the system can be tested prior to installation.
Typically, the GateKeeper will be positioned or mounted at or near the facility reception desk. This
enables the desktop reader to be connected, and door readers to be connected by longer cabling
fitted to wall and floor edges. This positioning also typically allows the GateKeeper to use the same
network cable access to the Internet router as used by the reception computer.
Fail Secure door locks will LOCK the door when the power goes off, and require power to unlock.
Fail Safe door locks will leave the door UNLOCKED when the power goes off, and require power
to lock.
Check with your local fire and government regulations as to which you can use. Fail-secure
systems are illegal in some areas.
Door lock, door lock power-supply, and any Push To Exit buttons are NOT supplied by GymMaster,
and should be sourced in advance by installer.
Note: If you use Fail Secure door locks, it is STRONGLY recommended that you
have alternative means by which you can physically unlock the door in case of
outage (loss of power, or no connection to Internet for a long period, etc).
Door lock MUST have its own separate power supply. Do NOT use the GateKeeper or
the GateKeeper power supply to power any mag locks or door strike.

Troubleshooting
Key Fob Assignment
To test the access control system, a test key fob is provided. If this test key fob is not available, a
new one can be assigned in the GymMaster software.
For members to check in, or enter your facility using a key tag, or swipe card, they have to have
one associated with them. This is the Key Fob field of the member's Details tab. When a new fob
is scanned on one of your readers it will be serialised to a sequential number; the first fob
being #1, the second #2 and so on. This number is represented in their Key Fob field. This
field can be set manually by typing the number associated with the fob, or you can select the
button to the right of the field with the tag icon on it. This will check for the most recent key fob
that was swiped on your designated default reader, and put the fob number in the field for you.
Make sure you click the [Save] button on the member after you set a Key Fob. The member
will also require a Membership with a Door Access Benefit. If the installation is occurring
outside the clubs open hours, you will need to update the Membership Type Doors Benefit to
allow 24/7 access.

Ensure the port on the Reader matches the port set in the software
If only one door reader is installed, the software will be set up with the assumption that you will plug
the reader into port 1 on the GateKeeper (The port farthest from the screen, as shown in the
diagram). Ensure that the relay wiring is on the same level as the port you have chosen for the
door reader.
To see which port the software is configured for, navigate to Settings > Door Readers >
GateKeeper Socket. If you want to plug the reader into the top port of the GateKeeper, update this
field and save.

Test the relay wiring to the magnet door lock
Once you have finished the wiring, you can test if the wiring is correct and working by using a
paperclip. Do this before plugging the connector into the GateKeeper socket.
Find a paperclip, straighten it and then bend it as depicted below. Connect the paperclip into the
two holes where the two wires connect to the magnet lock. You should be able to see the door lock
activate or deactivate, depending on the type of lock.
To demonstrate, if the lock mechanism is unengaged (unlocked) before you connect in the
paperclip, it should be engaged (locked) after you connect the paperclip.
If the lock is engaged (locked) before you plug in the paperclip, it should become unengaged
(unlocked) after the paperclip is connected.
If that does not happen, it means that the wiring has not been done correctly on the lock
mechanism. Please check the power supply for the lock and other related wiring.
