Installation Guide
Introduction
This installation guide provides basic instructions for common ALC Outdoor LF BUS Beacon with Loop installation scenarios.
CAUTION!
It is important that you read and follow the instructions in this document. If you have questions, call your local Elpas support representative.
Reasonable effort was 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 in 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.
Product Description
The Elpas ALC LF BUS Beacon is a fully supervised, 125KHz emitter
that adds instantaneous location, choke-point (e.g. gate or door),
awareness to security, and safety applications. The sealed beacon
enclosure enables installation outdoors where long range LF coverage is
often needed.
The ALC LF BUS Beacon generates a user-adjustable, elliptically shaped
field up to 4m/13ft (perpendicular to the device) and 3.5m/11.5ft (parallel
to the device) in radius that can be used to cover a single interior
doorway. Optionally, up to three ALC LF BUS Beacons can be deployed
in ‘Primary–Secondary’ (up to two secondary devices) topologies to
cover large double-doors or architectural complex indoor entrance/exit
areas. The DIP Switch setting determines which is primary and which is
secondary.
The ALC LF BUS Beacon with external loop antenna generates a user-
adjustable, cylindrically shaped field of 2.2m high (nominal range) along
the loop cable (for a 3-conductor cable loop of 1.4mm wire diameter
(1.5mm
2
), buried 5cm under concrete or asphalt pavement). The device
supports loop cables 10-80m long.
The ALC LF BUS Beacon contains two general purpose analog inputs
(IN1 and IN2) and two open collector outputs (OC1 and OC2). The
device forces a choice between IN2 and OC2. The device also provides
the choice of either two digital inputs or two 26-bit Wiegand device
outputs. The DIP Switches setting determines these selections.
Note:
Installation should be done only by a professional.
ALC with Loop Beacon - Sample Network Topology
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 Primary BUS Beacons) which are
wired together with Elpas RS-485 Junction Boxes (P/N:5-JBA10485).

Front Cover Tamper Contact:
ALC BUS Beacons contain an optical tamper which
indicates non-authorized attempts to remove the device front cover tray when in
operation.
Status LED:
All BUS beacons contain a Red, Green and Amber LED array that
detail the status of the devices:
Green LED
o
Unregistered:
Flashes once/second
Red LED
o
Invalid ID:
Flashes once/second - See page 4 for additional details
o
Device Back Tamper:
Flashes once/second
o
Output Activated:
Flashes once
o
Synch Cable Disconnect
(in secondary): Flashes continuously.
Orange LED
o
Continuous indicates normal state
o
Flashes to indicate the front cover is not properly closed
Note:
o
LEDs are visible only when front cover is removed.
o
LED colors may also be controlled remotely as ELC Actions or Eiris
Outputs.

RS-485 Interface:
ALC BUS beacons contain a female RJ-11 connector to link to
the RS-485 Junction Box. This connector transfers both power & data. (See page 2
for details)
Buzzer:
The beacon has a buzzer that sounds when an improper ID Address is
assigned. (See page 4 for details.)
General Purpose Inputs:
ALC BUS Beacons include one set and one selectable
general purpose inputs. (See page 6 for details.). The beacons also provide the
choice of either two digital outputs or one 26-bit Wiegand device output. (See page
6 for details.)
Output (User Selectable):
The beacons provide either two digital outputs or one
26-bit Wiegand device output. (See page 6 for details.). The beacons also include
one set and one selectable open-collector outputs.
Important:
An electric current runs through the LF coil. The current is especially
strong at the vias. Do not touch.

IMPORTANT
: BUS Beacons
MUST BE
powered-down while you wire the
unit’s I/Os and when you connect to the RS-485 BUS. This prevents
accidental damage to the devices caused by shorts/spikes
.
