Keri Systems LC-208 User Manual

Wiegand Elevator Control Panel

Keri has modified its PXL-250W Tiger Controller and SB-293 Satellite Board to tailor a system for
Wiegand reader, elevator control applications. The LC-202W Elevator Control Panel is made up of
an LC-200W Tiger Controller Board and an SB-200 Satellite Board, together in a standard PXL­250 enclosure. The LC-208W Elevator Control Panel combines four LC-200W panels with four
SB-200 Satellite Boards in a rugged enclosure.

The LC-202W provides two floor increments of elevator control at an economical price. Users can
mount a single Wiegand Reader inside an elevator cab and connect it to up to 12 LC-202Ws to
control floor access for up to 16 floors. Used in conjunction with Doors32 software, this
combination can be a very cost-effective elevator control solution.

The LC-208W provides eight floors of elevator control in a small, integrated package. As with the
LC-202W, a single Wiegand Reader is mounted inside an elevator cab and then is connected to the
LC-208W, providing controlled access for up to eight floors in a single enclosure.

Any combination of LC-202Ws and LC-208Ws may be combined to control greater than eight
floors.

Check with local authorities when installing Elevator Control panels. Your elevator
control application must meet all local and national safety codes. The Main or
Lobby Floor cannot have access control applied – all people must be able to exit the
elevator at all times on at least one common, ground-level access floor.

LC-202W/LC-208WQuick Start Guide

1.0 Considerations

To ensure timely operation, the following considerations apply when using Doors32 software for
elevator control.

• One reader in the elevator car controls access for all floors. This reader is attached to all antenna
inputs at each controller assigned to a floor. This wiring scheme results in the one reader being
responsible for access requests for all floors.

• The reader's read range is reduced, possibly up to 25%, due to the reader signal being shared
between multiple controller antenna inputs.

• To ensure the Wiegand reader signal reaches all controllers with good signal strength, a
Wiegand Distribution Amplifier (P/N 04197-001) is required.

• The reader's LED and beeper are used to indicate card presentation only, and does not indicate if
access has been granted or denied as in a standard access control reader application.

• User card presentation to the reader is critical. To ensure that all controllers have the opportunity
to respond to a card read, the card must be presented to the reader for a greater period of time
(perhaps up to 2 seconds depending upon the length of the cable run and the number of
controllers attached to the network). This allows all antenna inputs on all controllers the time
necessary to respond to the card.

2.0 Hardware and Software Operating Requirements

All standard hardware and software requirements for Doors32 software apply (refer to the Doors32
Users Guide – P/N 01821-002). To support elevator control, the following additional software and
firmware requirements must be met.

• The Doors32 software must be at revision 3.42 or greater.

• The controller firmware must be at revision 6.3.42 or greater.

3.5 Controller Memory Retention

• 5 year lithium battery backup to support controller RAM and real-time clock

3.6 Floor Control Relay Contact Rating

• 1 Amp @ 24 VDC

When connecting to elevator control systems and the floor selection buttons, please verify the
elevator system voltages. Most elevator systems operate on DC or AC voltages higher than the 24
VDC @ 1 Amp rating at which Keri Systems’ elevator controllers are rated.

Keri Systems recommends establishing a system connection point at which the access control
system and elevator control system connect, and to which both the access control company and the
elevator company have access. This assists in making the connections between the systems and in
allowing for independent system troubleshooting.

• If the system voltages are different (or if you wish to fully protect the access control system
from transient voltage spikes), these connections should be made via isolation relays or relay
control boards.

• If the system voltages are the same and both systems are fully protected, or if the system
connections are made between dry relay contacts, you may only need to use a terminal strip for
these connections.

Please consult your local building codes for proper installation requirements and check with local
permit departments to verify compliance. Elevator systems have Life Safety requirements and may
also require a connection to a fire control system.

4.0 Controller Installation

Sections 4.1 and 4.2 are quick lists of things to do and not to do when installing LC-202 and LC­208 panels.

4.1 Do

• Plan ahead to meet power and telephone requirements for your system (1 phone line for the host
computer and one for each master LC-200W in each network).

• Mount controllers and the distribution amplifier (for LC-202W applications) in environmentally
suitable areas – they require protection from weather and from temperature/humidity extremes.

• Mount the controller and the distribution amplifier (for LC-202W applications) at least 3 feet
away from the controller's power supply to prevent EMI radiated from the power supply from
affecting the controller.

• Use the enclosure as a mounting template to mark drilling holes for permanent mounting.

• Consider mounting requirements - central versus distributed.

- Central mounting places all controllers in one location, running lengths of cables out to each

door to support readers, inputs and outputs.

- Distributed mounting places each controller near the door it supports running short lengths

of cable out to each door, but running a long network communication cable.

• Note the locations of the knockouts in the enclosures and remove the appropriate knockout for
the easiest cable routing into the controller.

• Route all controllers in a network in a single, continuous daisy-chain.

• Route cables in accessible areas for ease of maintenance.

• Connect all controllers to a quality earth ground.

• Add transient suppression across electric devices attached to a controller output.

• Verify the controller's supply voltage is 12 VDC – long power line runs cause a drop in voltage
at the end of the run.

• Verify proper operation of the host computer's COM port.

• Attach the reader to be used for card enrollment to the master controller (this reader can be used
for access control as well as enrollment, but during the enrollment process the door associated
with the enrollment reader will not allow access until the enrollment process is complete).

LC-202W/LC-208WQuick Start Guide

4.2 Do Not

• Make modem phone line connections through PBX telephone switching systems - most
modems are not compatible with PBX systems leading to disconnection problems with the
modem.

• Locate the LC-200W controller near EMI sources - EMI sources can affect the performance of
the controller.

• Use switching power supplies - they are EMI sources.

• Route network and reader cables beside power cables - transients on the power cables may be
picked-up by network and reader cables.

• Stretch or over-tension cables.

Wiegand Elevator Control Panel

• Route cables over sharp objects.

• Let the cables get tangled.

• Mix LC-200Ws with PXL-100s in the same network.

• Connect earth ground to the network cable shield - the LC-200W automatically connects earth
ground to the shield at one point on the network to prevent ground loops.

• Use gender changer plugs when making RS-232 serial communication connections (unless you
know it is a "straight-through" plug) - gender changers may have internal wiring changes that
can disrupt communications.
