Figure 2. New connection diagram for standard peripherals to keyboards with new terminals
5.1.2. BM0900
The BM0900 modular base is designed for 230V mains voltage (AC1 AC2). It can be powered by
an external DC power supply (+24V and GND sockets). Connecting the rest of peripherals is
identical to that of keyboards.
5.1.3. Common part for KDC39xx and BM0900
The KDC39XX and BM0900 keyboard supports DC locks and electromagnetic jumpers. The
supported voltage range is from 6V up to full supply voltage. Locking bolt is connected to LOCK
(positive potential) and PGND (ground) cables (in BM0900 respectively R+ GND). The voltage and
polarization of lock changes with parameters – there is no need for additional relay. Permissible
load of LOCK output is 0.5A.
Apparatus line is compatible with existing PC255, PC999 and PC512 devices. Permissible line
resistance of apparatuses is 10Ω (total to L+ and L-). The KDC3915 keyboard does not have a built-
in apparatus line.
The keyboards and modular base can be connected to a locking button between AUX and PGND
terminals. The button controls the bolt with standard settings, but it can also be used as OC trigger.
It is possible to connect a parallel LED to the button illumination.
The OC output can be used to control an additional relay (e.g. for the gate). If the relay is
connected, it is necessary to connect the LED according to diagram in Figure 1. The OC output is
also used to switch on the ZV-18 video bus power supply. Terminal P- is connected to OC terminal,
while P+ is connected to PWR+24V. Such a connection requires OC control configuration for the
duration of call (pair x298) and blocking OC control from the P2 button (pair 382).
