Keri Systems LC-508 User Manual

Proximity Elevator Control Panel

Keri has modified its PXL-500P Tiger Controller and SB-593 Satellite Board to tailor a system for
Proximity elevator control applications. The LC-502 Elevator Control Panel is made up of an LC­500P Tiger Elevator Controller Board and an SB-500 Elevator Satellite Board, together in a
standard PXL-500 enclosure. The LC-508 Elevator Control Panel combines four LC-500 panels
with four SB-500 boards in a rugged enclosure.

The LC-502P provides two floor increments of elevator control at an economical price. Users can
mount a single MS Series Proximity Reader inside an elevator cab and connect it to up to 12 LC­502Ps to control floor access for up to 24 floors. Used in conjunction with Doors software, this
combination can be a very cost-effective elevator control solution.

The LC-508P provides eight floors of elevator control in a small, integrated package. As with the
LC-502P, a single MS Series Proximity Reader is mounted inside an elevator cab and then is
connected to the LC-508P, providing controlled access for up to eight floors in a single enclosure.

Any combination of LC-502Ps and LC-508Ps 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.

1.0 Important Considerations

To ensure proper operation, the following considerations apply when using Doors software for
elevator control.

• Up to 24 floors can be controlled using any combination of LC-502Ps and LC-508Ps.

• One reader in the elevator cab controls access for all floors. This reader is attached to all
antenna inputs at all controllers in the elevator control system. This wiring scheme results in the
one reader being responsible for access requests for all floors. Since the reader’s signal is being
shared between multiple controller antenna inputs the reader's read range is reduced, possibly
up to 25%.

• User card presentation to the reader is critical. T o ensure that all controllers have the opportunity
to respond to a presented card, the card must be presented to the reader for a greater period of
time – 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. If a card is not presented correctly, controllers that have not recognized the
card will not allow access to the floors they control.

• The reader's LED and beeper are used to indicate correct card presentation only, and does not
indicate if all controllers have recognized the card or if access has been granted or denied (as
done by a standard PXL-500 Tiger Controller).

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

• 24 VDC @ 1 Amp

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. Each installation should use isolation relays.

Keri Systems recommends establishing an interconnection 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.

Proximity Elevator Control Panel

4.0 Controller Installation

Sections 4.1 and 4.2 are quick lists of things to do and to not do when installing LC-502P and LC­508P 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-500P controller in each network).

• Mount controllers in environmentally suitable areas – they require protection from weather and
from temperature/humidity extremes.

• Mount the controller at least 3 feet away from the controller's power supply to prevent EMI
radiated from the power supply from affecting the controller.

• Use isolation relays where needed.

• 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.

Proximity Elevator Control Panel

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 a LC-500P controller near EMI sources - EMI sources can affect the performance of the
controller.

• Locate a reader near EMI sources - EMI sources can affect the performance of the reader.

• Use non-approved switching power supplies, or high noise/high ripple current - 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.

• Route cables over sharp objects.

• Let the cables get tangled.

• Mix LC-500Ps with PXL-100s in the same network.

• Connect earth ground to the network cable shield - the LC-500P automatically connects earth

Quick Start GuideLC-502P/LC-508P

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.

5.2.4 Earth Ground and Power

The LC-502P panel requires 12 VDC power at 750 mA. You must make a quality earth ground
connection to the controller prior to connecting the DC power lines. The earth ground provides
protection for the controller and ensures the best possible operating conditions. Possible sources for
earth ground are a ground rod, a cold water pipe, a steel building frame, the electrical system
ground at the breaker/fuse box, or the telephone system ground. Make the earth ground and power
connections per the information in Table 4 and Figure 9.
