LC-202W/LC-208W
Quick Start Guide
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 LC-
208 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).
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.
