LC-202P/LC-208P
Quick Start Guide
3.4 Current Draw
• 500 mA maximum current draw for a Controller with all options installed (SB-200, LCD-1, and
Reader)
• 120 mA maximum for a LC-200P Controller
• 150 mA maximum for an SB-200 Satellite Board
• refer to Table 1 on page 3 for Reader current draw
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.
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.
