LCK and BELL outputs
LCK and BELL are transistor (open collector) outputs which can control 15V/1.0A load. In standard scenario
of door control, LCK output is dedicated to control door lock while BELL output is dedicated to control alarm
signalling device and door bell but they can be used for any other functions which are configured using AC-
MAX management software.
Output polarity can be configured as normal or reversed. Output with normal polarity represents high
impedance in normal state and is shorted to ground when triggered. Output with reversed polarity operates
with inverted logic. It is shorted to ground in normal state and represents high impedance when triggered.
The configuration of output polarity is done within low level configuration using AC-MAX HW software. By
default, outputs are configured with normal polarity.
DC and DR inputs
DC and DR are parametric inputs which can be configured as NO, NC, EOL, 2EOL, 3EOL or DW (Double
Wiring) types. It is also possible to configure input response time which defines minimal pulse which can
trigger the input. The configuration of input electrical parameters is done within low level configuration by
means of AC-MAX HW software.
Each input can be assigned with function. In standard scenario of door control, DC input is dedicated to
connection of door contact while DR input is dedicated to connection of exit button. Inputs are assigned with
functions using AC-MAX management software. Default factory settings for both inputs are as follows:
•
DC input: NC/50ms
•
DR input: NO/50ms
VDR power output
VDR power supply output is dedicated to supply door lock, alarm signalling device and other door related
devices. The terminal VDR+ is protected with 1.0A electronic fuse. The terminal VDR- is internally shorted to
ground (GND). Green LED indicator is located at the VDR+ terminal to signal voltage at the output.
