Elpas Proximity BUS Reader

Wiring Guide

P/N: 5-LFA00125

Introduction

This wiring & installation guide provides basic instructions for common Proximity BUS Reader installation scenarios.

CAUTION! It is important that you read, understand, and follow the instructions in this document. If you have questions, call your local VT support representative.

Product Description

he Elpas Proximity BUS Reader is a 125KHz, EM4100

ompatible; indoor/outdoor surface mounted proximity reader.

he reader features low power consumption, high reliability,
nd consistent read ranges (up to 10cm /4 inches), regardless
f card or tag.

Designed for harsh indoor/outdoor environments, the reader’s
solid state electronics is housed in an epoxy potted, IP-67
rated, weatherproof thermoplastic casing that ensures years of
maintenance free deployments.

The Proximity BUS Reader contains an onboard I/O that
enables the monitoring of one alarm sensor and control of one
digital open-collector output. The proximity reader also includes
a 2m/6.5ft long RS-485 power/data cable for interfacing to a
Elpas BUS Master (a RF IP Reader or an ELC Controller) via a
RS-485 Junction Box (P/N:5-JBA00485).

Note: An Elpas RS-485 BUS may contain up to fifteen Elpas BUS

evices (such as RF or IR Readers, Elpas Display Panels, LF Exciters,
r other Proximity BUS Readers) which are wired together using Elpas

RS-485 Junction Boxes.

Mounting Considerations

The Proximity BUS Reader should be wall mounted, adjacent to
the opening side of the door (outside of the protected area), at a
height of approximately 1.2m/4ft above the floor

Note: When installing Proximity BUS Readers on adjacent doors,
make certain that the minimum distance between readers is at
least 60cm/2.0ft to ensure proper operation.

Mounting Procedure

1. Insert a screwdriver into the recess at the bottom of the case,
and separate the cover from the reader.

2. Place the base on the installation surface, mark two screw
holes, drill the holes, and insert the supplied plastic anchors, if
necessary.

3. Fasten the base to the mounting surface, using the two #6 Tap
screws supplied with the reader.

4. Replace the reader’s cover, ensuring that the cover is aligned
with the reader. This enables the LED to be visible.

LF Proximity BUS Reader - Network Topology

Note: Do not install the Proximity BUS Reader directly onto a metal

surface, since can significantly decrease the effective read range of
the device. If you have to mount the reader onto a metal surface,
insert a RDR-BACK (P/N: 3-6317-0) between the device’s reader
base and the metal surface.

Proximity BUS Reader – Wiring Guide

LED Status Indicator

The Proximity BUS Reader contains a tri-colored (Red, Green and
Orange) software configurable LED array that can be used to specify
the status of the device.

Refer to the Eiris Software (V4.7.1 or higher) or the ELC Programmer
Software (V2.1 or higher) Configuration Guides for setup details.

General Purpose Inputs

The Proximity BUS Reader have two general purpose inputs
designated IN1 and IN2. EOL supervision may be added to either
of these inputs to detect: Open, Close, Line Cut and Line Short
conditions using an End-of-Line Terminator (P/N: 5-IOX00001).

By default, the Red LED is used to indicate the following device
trouble conditions:

o The reader is unregistered (flashes once/sec.)
o The reader has lost RS-485 communication (flashes once/sec.)

RS-485 Interface

The Proximity BUS Reader has one 2m/6.5ft, 6-wire AWG-26
power/data cable with a male RJ-11 connector (6P6C) for connecting
to the RS-485 Junction Box.

I/O Interface

The Proximity BUS Reader also has a 2m/6.5ft, 4-wire AWG-22 cable
with ends for connecting two inputs and one digital output.

Color Conductor Details

Black Ground
Red Digital Output
Green Input 1 (IN1)
White Input 2 (IN2)

IMPORTANT: BUS Exciters MUST BE powered-down while wiring the unit’s
I/Os and when connecting to the RS-485 BUS. This will prevent accidental
shorts/spikes to cause damage to the devices.

Recommended Cable: 22 AWG, unshielded/twisted pair.

Digital Output

The Proximity BUS Reader has one general purpose digital output,
which provides open-collector switching (up to 100mA, 28VDC).

Recommended Cable: 22 AWG, unshielded/twisted pair.

RS-485 BUS/Stub Topology

The RS-485 BUS MUST BE wired using a BUS/Stub topology where the BUS Master (a RF IP Reader or an ELC Controller) is connected
anywhere along the BUS. The topology supports data transmission between the BUS Master and up to 15 Elpas BUS Devices (such as RF or IR
Readers; LF Exciters primary & secondary), Elpas Display Panels and 6x6 I/O Modules using Elpas RS-485 Junction Boxes (P/N: 5-JBA00485).

IMPORTANT NOTE: Only 1 RF IP Reader/ELC Controller and up to 7 RF BUS Readers may coexist together on a single BUS.
200M/650Ft: Max. BUS length 10M/30Ft: Max. Stub length 100 Ohm Termination: Required each end of the BUS.

Recommended RS-485 Backbone Cable Type: CAT5 Solid (4x2x26AWG)
For Power: Use three-twisted pairs (six conductors) between RS-485 Junction Boxes

For Data: Use one-twisted pair (two conductors) between RS-485 Junction Boxes
