Elpas Proximity BUS Reader

P/N: 5-LFA00125

Installation Guide

Product Description

The Elpas Proximity BUS Reader is a 125KHz, EM4100
compatible; indoor/outdoor surface mounted proximity reader.
The reader features low power consumption, high reliability, and
consistent read ranges (up to 10cm /4 inches), regardless of card
or tag.

Designed for indoor/outdoor environments, the reader’s solid
state electronics is housed in an epoxy potted, (IP-67 rated), of
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 devices
(such as RF or IR Readers, Elpas Display Panels, LF Beacons, or other
Proximity BUS Readers) which are wired together using Elpas RS-485
Junction Boxes.

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.

Introduction

This installation guide provides basic instructions for common Proximity BUS Reader installation scenarios. For UL 294 Compliant Applications
refer to page 4 of this document for a listing of applicable installation considerations.

CAUTION: It is important that you read, understand, and follow the instructions in this document. If you have questions, call your local Elpas
support representative. All reasonable efforts have been made to ensure that the specifications and other information in this guide are accurate
and complete at the time of its publication. Nonetheless, all information contained within this document is subject to change at any time without
prior notice. Any modifications to this equipment without prior written consent of Elpas Solutions Ltd. will void all warranties including the
pertinent regulatory certifications and as such revoke your authority to operate this product. Furthermore unauthorized modifications may also
result in damage to this device and may cause a safety hazard to the users.

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.

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.

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.

IMPORTANT: BUS Beacons 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.

General Purpose Inputs

The Proximity BUS Reader has two general purpose analog
(N.O.) dry contact inputs for monitoring alert sensors or emergency
call buttons 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-of­Line Terminator (P/N: 5-IOX00001).

Note: Elpas End-of-Line Terminators have not been evaluated for use in UL Applications.

Recommended Cable: 22 AWG, unshielded/twisted pair.

Digital Output

The Proximity BUS Reader has one dry contact open-collector
digital output (up to 100mA, 28VDC) for actuating an alert
response device.

Note: The output is resistive loading only, there is no power factor.
Recommended Cable: 22 AWG, unshielded/twisted pair.
