Weight: 4 Kg ( 15 Kg for ET8/480PT)
Equipment: 33 1500 Ohm input balancing resistors, 2 termination resistors for 680 Ohm
serial line, small bag with 4 5x54 threading screws and 4 S8 wedge, micro-
switch against housing opening and removing (Against house-breaking kit
with inertial sensor and analysis board for ET8/480PT), rubber-sheathed
cable with connector for remote reader (not included as part of ET8/480S
equipment), technical and programming manual, Cd programming with
PDF manuals.
NOTE:
The transponders must be connected directly to the specific terminal board of the control unit indicated as A and B
and may be powered by the mains supply terminals of the keyboard. They must be connected according to this
manual’s diagrams by using a screened cable for theft and flame prevention with a minimum section of 0.75 mm2 for
short lengths and a minimum section of 1mm2 or greater for long lengths. Maximum connection distance between
control unit and the last transponder is 1,000 metres with transponders evenly distributed. For the system’s autonomy
and powered load’s optimization, it is reccomended the use of remote mains supply boxes such as model C11K,
especially when the control unit is used with several keyboards, transponders and volumetric sensors.
