Link-Scan Controller

Features

Large User base capabilities – Real Time control of up to 8000 tag code holders enable one system to

cater for all the staff.

Leading passive transponder proximity technology design for tags and readers non-contact and no

batteries.

On-line editing capability – On-line ‘dead terminal search‘ reinstates to full speed operation newly

installed terminals thus no need to stop and re-initialize the system.

Off-line capability – Totally independent of a host system once setup, thus release the host PC for other

duties.

Large transaction memory – Maintains a history of up to 6000 transactions, until polled by a host.

Effective zoning capability – Up to 16 separate anti-passback groups, each with 1 to 16 doors, facilitates

control of logical areas in buildings.

Simplicity and low cost of installation – Up to 16 Link-Scan Controllers multi-dropped, each having a

maximum of 15 terminals, reduces wiring. Only 2 pairs of wires needed for power and communications.

Software flexibility- Various host software suites, having full reporting, with time and attendance, caters

for all users needs.

Total user control – Each tag allocated triple time and area code from a selection of 256, ensures total

control of each tag holder’s movements.

Exceptional speed of communication – 19200 Baud polling between Controller and Terminals provide

almost instant response, and 1 km communication removes distance restrictions.

Full Anti-passbacks capability – Supports both Restricted and Relaxed modes with selectable

simultaneous or Alternate movement.

Flexible Timing of access points – Integrated dual relays are duration programmable to assist in setting up

the required timing for even the most difficult access point.

Self diagnosis – Slow poll list, to prevent faulty terminals hanging up the system.

Security of electronics – The Remote scanners can be located up to 25 metres away, thus ensures the

vital connections in the Controller can be in a secure area.

Digital Input capabilities – 4 general purpose digital inputs are accommodated. They are used for ‘door

open’ sensing and push-button requests to open the door. If these features are not required, they can be used to

allow the interfacing of user specific sensors (e.g. door sense, latch override, loop detectors), to effect

conditional tag reading on the Controller only. These inputs can be as general purpose alarm inputs.

Tamper resistant capability – The unit comes with ‘‘anti-tamper’’ cabinet.

Models available – Link-scan Controller comes in two models:

LSC01GBx00 Model 20 – 2000 Tag System Network Controller

LSC02GBx00 Model 80 – 8000 Tag System Network Controller

Applications:

For the control of access in:

Office Blocks

Parking Garages

Block of flats

Factories and industrial premiums

Warehouses, etc.

As a clocking point for time and attendance operation, using designated clocking terminals within the access

control system.

The proximity system requires no physical contact and is thus useful in particularly harsh environments such as

dirty and dusty factories, outdoor marinas and fishing wharfs.

High security proximity cards ensure maximum security against duplication.

For use in remote areas where the proximity system can be used without the need for regular preventative

maintenance visits by technician.

Memory:

Non-volatile memory (battery backed)

Model 20: up to 2000 tags and between 1500 and 2500 transactions

depending on number of tags entered.

Model 80: up to 8000 tags and up to 6000 transactions.

Size (Approximately):

L = 161 mm, B = 90mm, H = 45mm

Digital Inputs:

4 x Dry contact inputs, protected to ± 80 V transients and ± 20 V continuous.

Relay output:

Integrated 2 x SPDT @ 1.5 A, 30 V DC / 250 V AC

RS485 Port 1:

Link up to 15 Link-Scan Terminals @ 19200 baud, 8 bit, no parity and 1 stop

bit.

RS485 Port 2:

Link up to 15 similar Link-Scan Controllers to host @ 2400 / 9600 baud,

8 bit, no parity and 1 stop bit.

Scan Channels:

Two, with 2 read heads each. One of the two is integrated into the cabinet

base in parallel with an optional remote scanner.

Remote Scanner:

Units are designed to operate at a maximum of 25 metres from the

electronics, can be fitted in harsh environments, and includes the three

status LEDs ( as are fitted to the main cabinet), and an internal buzzer.

Status:

Is indicated by light emitting diodes. One indicates ‘Power on / Present Tag’,

the second lights up on the receipt of a valid code, ‘Access Allowed’, whilst

the third lights on ‘Access Denied’

Reading Distances:

The distance between the passive tag and readers is approximately 100 mm

from the coils (in base of cabinet) but depends on the type of tag used.

unit should not be mounted on or adjacent to any metallic surface, including

steel reinforcing rods. Screw holes are provided in reader base.

Coil Frequency:

Link-Scan Terminal

LST01YYX00 – Network Terminals, the slave of the Link-Scan Controller, up to 15 units, will instantly be serviced simultaneoulsy. Each has door sensing facilities and can be directly linked to a controller over a kilometer away.

LST01YYX01- Network Terminal with Link-Scan Bar Code Option.

Features

Exceptional terminal communication speed – Powerful communication protocol @ 19200 baud via a RS

comms Link achieves both distance and speed plus economy of cabling.
