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
software. By default, outputs are configured with normal polarity.
DC and DR inputs
DC and DR are parametric inputs that can be configured as NO, NC type. It is also possible to configure
the input response time which defines the minimum pulse that can activate the input. The configuration of
the electrical input parameters is done within the low-level configuration by means of the AC-MAX
software only NO or NC.
Each input can be assigned to a function. In the standard door control scenario, the DC input is dedicated
to the connection of the door contact, while the DR input is dedicated to the connection of the exit
button. The inputs are assigned to functions via the AC-MAX management software. The factory default
settings for both inputs are as follows:
•
DC input: NC/50 ms
•
DR input: NO/50 ms
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.
