Product liability
In compliance with the liability of the manufacturer for his products as
dened in the German “Product Liability Act”, compliance with the infor-
mation contained in this brochure (product information and intended use,
misuse, product performance, product maintenance, obligations to provide
information and instructions) must be ensured. Failure to comply releases
the manufacturer from his statutory liability.
1 Safety
1.1 Intended use
The movement detector GC 308 R may only be used for the activation of
automatic sliding, curved sliding, folding, swing or revolving doors with
GEZE drives.

direction of
emergency
exit)
1.2 Safety notes
àThe prescribed mounting, maintenance and repair work must be per-
formed by personnel authorised by GEZE. Any attempts at repairs by
unauthorised personnel cancel the factory guarantee.
àThe device may only be operated with safety extra-low voltage (SELV)
with electrically protective separation.
àThe country-specic laws and regulations are to be observed during
safety-related tests.
àIf unauthorised changes are made to the system, GEZE cannot be held li-
able in any way whatsoever for any resulting damage, and the statement
of approval for use in escape and rescue routes is no longer valid.
àGEZE does not accept any warranty for combinations with third-party
products.
àOnly original GEZE parts may be used for repair and maintenance work.
àObserve the latest versions of guidelines, standards and country-specic
regulations, in particular:

Safety GC 308 R
4
àASR A1.7 “Doors and gates”
àDIN 18650 “Building hardware – Powered pedestrian doors”
àDIN EN 16005 “Power operated pedestrian doorsets – Safety in use –
Requirements and test methods”
àAccident-prevention regulations, especially BGV A1 “General regula-
tions” and BGV A2 “Electrical installations and equipment”.
àThe risk assessment and installation of the sensor and the door system in
compliance with national and international regulations and door safety
standards are the responsibility of the door manufacturer.
àAny uses of the device other than those described in this manual do not
correspond to the approved purpose and cannot be guaranteed by the
manufacturer.
1.3 Safety-conscious working
àSecure workplace against unauthorised entry.
àWatch the swivelling range of long system parts.
àSecure the cover/drive panels against falling.
àAttach safety stickers to glass leaves.
àDanger of injury with opened drive. Hair, clothing, cables, etc. can be
drawn in by rotating parts.
àDanger of injury caused by unsecured crushing, impact, drawing-in or
shearing spots.
àDanger of injury due to glass breakage.
àDanger of injury due to sharp edges in the drive.
àDanger of injury during installation through freely moving parts.
1.4 Environmentally conscious working
àWhen disposing of the door system, separate the dierent materials and
have them recycled.

DescriptionGC 308 R
2 Description
The GC 308 R radar sensor has been designed for use as an opening pulse
generator on automatic doors. Due to the Doppler eect, the sensor
detects movements, whereby a distinction is made between approach and
distance to the detector. It is not possible for several sensor systems to inu-
ence each other and result in a hazard.

3 Work to be done before installation
3.1 Installing the drive
XMake sure that the cover of the drive is tted correctly and earthed.
3.2 Positioning the sensor
The GC 308 R is used as an activation sensor for automatic doors.
àThe sensor must be mounted above the door in the case of sliding,
curved sliding, folding and revolving doors. Ideally, the ows of people
walk directly towards the sensor. If the scanning area does not cover the
entire opening width or if ows of people from dierent directions are to
be expected, several GC 308 R can be used.
àIn the case of swing doors the sensor must be mounted on the hinge side
above the swivelling axis.

6.5 Access code
An access code (1 to 4 digits) is recommended for sensors which are in-
stalled close together.
To save the access code 0-9 0-9 0-9 0-9
To delete the access code 0-9 0-9 0-9 0-9 0
After the access code has been saved, this code must always be entered to
unlock the sensor.
If you have forgotten the access code: Switch the power supply o and on.
After switch-on you have 1 minute to unlock the sensor without entering
the access code.
