tart Guide
Keri has modified its PXL-500W Tiger Controller and SB-293 Satellite Board to tailor a system for
Wiegand reader, elevator control applications. The LC-502W Elevator Control Panel is made up of
an LC-500W Tiger Controller Board and an SB-500 Satellite Board, together in a standard PXL-
500 enclosure. The LC-508W Elevator Control Panel combines four LC-500W panels with four
SB-500 Satellite Boards in a rugged enclosure.
The LC-502W 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 16 LC-502Ws to
control floor access for up to 32 floors

. Used in conjunction with Doors software, this combination
can be a very cost-effective elevator control solution.
The LC-508W provides eight floors of elevator control in a small, integrated package. As with the
LC-502W, a single Wiegand Reader is mounted inside an elevator cab and then is connected to the
LC-508W, providing controlled access for up to eight floors in a single enclosure.
Any combination of LC-502Ws and LC-508Ws may be combined to control more 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. Each installation should use isolation relays.
1.0 Considerations
To ensure timely operation, the following considerations apply when using Doors 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.
