Controller Installation
Sections 4.1 and 4.2 are quick lists of things to do and not to do when installing LC-502 and LC-
508 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-500W in each network).
•
Mount controllers and the distribution amplifier (for LC-502W applications) in environmentally
suitable areas – they require protection from weather and from temperature/humidity extremes.
•
Mount the controller and the distribution amplifier (for LC-502W 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.
