Battery Life
The GT8 terminal is tted with a Lithium-Ion battery which typically has a service life of between 3 and 5
years. In order to ensure the continued reliable operation of the back-up battery function we recommend
regularly checking the condition of the battery and replacing it when it has reached the end of its service life.
The GT8 is also tted with a button cell type battery on the main PCB to maintain the real-time clock (RTC)
of the device when power is removed. This battery typically has a service life of around 10 years. The
battery should only be replaced by suitably qualied engineers and care should be taken to avoid damage to
the PCB caused by ESD (ElectroStatic Discharge). Replacement batteries must be of the same type as the
original, and the old battery should be disposed of in accordance with local regulations.
Care should be taken when recycling the terminal to ensure that the batteries are removed and recycled in
accordance with local regulations/legislation.
Maintenance
The GT8 terminal does not require any regular maintenance during its service life.
It is however recommended that periodically (once every 6 months) the condition of the battery should be
checked to see if there are signs that it’s reaching the end of its life. Occasionally, the battery may start
to swell towards the end of its life, if this is noticed, the battery should be replaced (Part Number: EM-BB-
2HR-A).
Cleaning
Cleaning of the outside of the terminal can be undertaken at intervals appropriate to the environment
that it is being used and the frequency of use. In all cases it is recommended that the surface of the
clock is wiped with a lint free cloth that has been dampened with up to 70% isopropyl alcohol. We do not
recommend spraying liquids directly onto the surface of the clock as this could potentially cause damage to
the electronics. Particular care should be taken when cleaning the display and biometric devices to prevent
damage.
Installation Safety
The GT8 clock should be installed in accordance with the instructions documented in this user guide. The
clock should be installed in compliance with any Health and Safety legislation and it is recommended that
any electrical or network connections to the clock are undertaken by a suitably qualied engineer.
The GT8 clock is designed to be installed indoors only with a normal ambient operating temperature
between 0-35 Deg C (32-95 Deg F).

PowerOptions
AC 110-240V via Adapter
The GT8 Terminal can be powered from an AC power outlet using an optional plug-top or wall wart power
supply. Adapters include
AE-PSU-PT-12VDC universal adapter with UK, Europe, Australia and US interchangeable AC plugs
AE-PSU-NA-12VDC adapter with US AC plug
DC 12V
The Terminal can be powered from a suitable
12Vdc power supply with 2.1mm DC plug centre
positive connected to the ‘+12V DC’ power in jack.
The supply should have a stabilised voltage output
of 12VDC ±5% with minimum 2A capacity. The
power supply should incorporate suitable overload
protection.
The GT8 power indicator will show blue when power
is supplied via the 12V power jack either with direct
DC connection or with an AC power adapter.
Power over Ethernet PoE
The GT8 may be powered via the Ethernet cable
with suitable upstream PoE+ switch or injector.
Supported standards
IEEE 802.3at (PoE+) injector provides Terminal
with 2000mA @12V
Note: PoE+ is recommended to ensure there
is sucient power available to support dierent
congurations of the terminal.
When the GT8 is running from PoE the power
indicator on the front of the Terminal will show green.

Page 15
PowerOptions
Battery Backup
As standard the GT8 is tted with a backup battery
(EM-BB-2HR-A) to run the Terminal should the normal
power supply fail, providing up to 2-hours runtime.
When the battery pack is installed the terminal will
continue to run when power is removed until the
battery charge level reaches its lower threshold. The
terminal may be shut down prior to battery exhaustion
by using the ‘Shut Down’ option accessible through
the launcher menu. Once shut down the terminal will
remain o until power is restored. When in the shut
down state there is very little draw on the battery and
it can remain in this state for extended periods. For
optimum battery life it is recommended that the battery
is charged a minimum of every six months if the unit is
in shut down for prolonged periods by applying power
to the Terminal.
Charging of the EM-BB-2HR-A battery pack is
managed by the GT8 terminal and depending on
power source typical recharge time from 0% to 100%
will range from 3 hours to 12 hours. Charging times
will be extended in elevated ambient temperatures to
protect the battery.
When the GT8 is running from battery the power
indicator on the front of the Terminal will show red.
The EM-BB-2HR-A battery pack comprises a
rechargeable li-Ion battery along with protection
circuitry to prevent safety hazards caused by
overload, over-charging or over-discharge.
WARNING: ONLY FIT BATTERY PACK
SPECIFIED, FAILURE TO OBSERVE MAY
RESULT IN FIRE HAZARD
Service life of the EM-BB-2HR-A battery pack is
typically 3 to 5 years depending on conditions
and regular replacement is recommended. The
battery may become swollen towards the end of
its service life, if swelling is observed the battery
should be replaced.
