DoorKing 2348 Elevator Control - Manual (Page 7)

Section 1 – Introduction
DoorKing's Model 2348-010 Elevator Control System provides complete elevator security and is used
to (1) restrict which floors visitors may have access to via the elevator(s) after they have been granted
access by a building resident, and (2) restrict which floors residents may have access to via the
elevator(s). Elevator control is typically used in high rise apartment building applications that are
equipped with this option and a DoorKing Model 1833, 1835 or 1837 Telephone Entry System, or the
DoorKing Model 1838 Multi-door Access Control System. This system also requires the installation of
an access device (card reader) in the elevator car to enable building residents to activate the floor
buttons according to the security level assigned to them.
1.1 General Information
Up to eight (8) elevators may be controlled by up to eight (8) DoorKing Access Control Systems
(1833, 1835, 1837, 1838) at four (4) entrances. Typically, a telephone entry system is installed at the
building entrance. The 2348-010 elevator control board(s) is located and installed close to the
elevator electronic control panel. A three conductor wire connects the 2348-010 board to the
telephone entry system. Resident access to different floors in the building is controlled by an access
device (card reader) installed in the elevator car and connected to the telephone entry system (or to a
Tracker expansion board) by routing the wiring along with the elevator car electrical umbilical cable.
The elevator control system is able to restrict elevator button operation by interrupting the button
wiring between the elevator car and the elevator control electronics. The elevator car floor button
wiring is routed through the relays on the elevator control board before being connected to the
elevator electronics. In this manner, the 2348-010 elevator control system may either open or close
the wiring to the floor buttons in the elevator car upon command, and thus either disable or enable the
desired floor button(s) for a programmed period of time.
