required current constantly and that it is cooled properly (do not wrap it in any
thermally insulating material, or use ill-ventilating covers, etc.!). The required current
depends on the count of buttons and other elements in the set and can be determined
for 12 V according to the following formula:
Basic unit without keypad
80 mA
Basic unit with keypad
200 mA
1 one-side extender unit
80 mA
1 two-side extender unit
100 mA
Camera
130 mA
Reader
150 mA
Display
200 mA
The above mentioned currents are maximum values at 12V.
Cable Arrangement inside the Cover
We recommend you to use a UTP cable (8-wire, approx. 5.5 mm output diameter) for
EntryCom connection. Push the cable into the groove on the left side of the cover. If
you combine this cable with another one (e.g. the electric lock 2-wire cable), insert the
2-wire first and then the UTP cable to prevent the 2-wire cable from falling out. You can
also fit the cables with common clamp tape.
WARNING! An improper cable arrangement may cause a malfunction of the
product. Before closing the cover, check all wires and the cover for perfect
closing.
Grounding Terminal Connection - Mandatory
Any person that gets in contact with EntryCom may carry an electrostatic charge of
several thousands of Volts. Drawing one’s finger near to the EntryCom metal panel
may result in spark discharge. The purpose of the grounding terminal is to protect the
