Call features:
- adjustable max. ringing time (standard 30 s, range 10 - 600 s)
- adjustable max. conversation time from the door station (standard 60 s, range 6 - 600 s)
- adjustable max. intercom conversation time (standard 60 s)
- at most one call on the bus at a time
- calls from the door station take precedence over intercoms
- a call from the door station will block uncalled monitors from activity, signaled by an LED (buses)
- if the called station is already talking, a warning tone will sound when you press the button on the doorbell and the backlight of the called station will not flash
- communication is only one-channel. The system intelligently switches between the doorman and the monitor. The problem can arise in noisy places such as kindergartens or near noisy roads. For use in nurseries, we recommend using a monitor with a handset or a Dahua IP system.
The system is not suitable for very busy places where there are several door stations in one D2 system. If multiple people repeatedly ring multiple door stations at the same time, the system may freeze. The problem is not, for example, with ordinary apartment buildings with two entrances, but kindergartens are especially problematic.
Card reader:
- enables contactless identification of the card holder and automatic unlocking of the entrance door
- card management directly from the door station
- RFID reader, for RFID cards 125 KHz, memory for max. 320 cards, two master RFID cards for configuration
- the software is capable of storing an ID consisting of a maximum of 8 digits. The allowed range is 0 - 1,677,214.
- two control RFID cards in the package, one control card for adding and the other for removing cards from the system (the control cards cannot be used for normal access, they are only used for system administration).
