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 Titanium 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 Titanium 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 Titanium 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 Titanium 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 Titanium 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.
