3.0 When Installing Controllers
DO
since this is a telephone entry system at least one phone line will be necessary, it is important to plan ahead to meet
power and telephone requirements for your system (if using a modem, the host computer will need 1 phone line, plus
one for each master controller in each network or each EntraGuard unit)
mount controllers in environmentally suitable areas - the EntraGuard Silver unit is weather resistant, but care should
be taken to avoid areas of weather/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 the enclosure as a mounting template to mark drilling holes for permanent mounting
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 (with the EntraGuard Silver controller as the
master)
route cables in accessible areas for ease of maintenance
connect all controllers to a quality earth ground
1
add transient suppression across electric devices attached to a controller output
use an isolation relay (P/N IRP-1) if attaching to a parking gate, a turnstile, or any application using a large electric
motor
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 or Ethernet/LAN WAN connection.
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 EntraGuard Silver controller near EMI sources - EMI sources can affect the performance of the controller
use switching power supplies - they are EMI sources
route network cables beside power cables - transients on the power cables may be picked-up by network and reader
cables
stretch or over-tension cables
route over sharp objects
let the wires get tangled
route the EntraGuard Silver controller as a slave to a PXL-250 master
route all controllers in a network in spur, hub, or loop configurations
connect earth ground
1
to the network cable shield - the EntraGuard Silver automatically connects earth 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
1. Ground wire is green, with or without yellow tracer.
