1.2 Safety instructions
àThe mandatory installation, maintenance and repair work must be per-
formed by properly trained 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
liable in any way whatsoever for any resulting damage, and the approval
for use in escape and rescue routes ceases.
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 directives, standards and country-specic
regulations, in particular:
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.

1.3 Safety-conscious working
àSecure workplace against unauthorised entry.
àWatch the swivelling range of long system parts.
àSecure the weather hood/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.
2 Description
The GC 304 R radar detector 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uence each other and result in a hazard.

3.2 Positioning the sensor
The GC 304 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 ow of people
will walk directly towards the sensor. If the scanning area does not cover
the entire opening width or if the ow of people from dierent direc-
tions is to be expected, several GC 304 R sensors can be used.
àIn the case of swing doors the sensor must be mounted on the hinge
side above the swivelling axis.
