The L1000 has a 3 digit, 7-segment LED display used with an “Admin” tag to programme the L1000 as
well as any LSH's linked to the system. The display brightness can be varied to suit ambient conditions.
UndernormalrunningconditionsthedisplayoftheL1000willindicate the 3 digit ID number of the tag. A
buzzer also sounds momentarily to indicate that the tag has been read by the reader. The LSHs have a
simpler display comprising only three LEDs and a buzzer to indicate status. The buzzer can be config-

Seven levels of anti-passback control are available in the networked version. Each reader is capable of
storingfourseparate counter valueswhichdecrementeachtime avalidtagispresented. This providesa
method of controlling how many times a person may use a particular asset (e.g. photostat machine,
sauna,etc).
Complex programming of the system can be done using only a single “Admin” tag, but a sophisticated
software system, called Lattice Ware (refer to page 66), is preferable as it provides an intuitive, graphical
user interface (GUI), via a connected laptop, or personal computer (PC). Lattice Ware provides sophisti-
cated reporting as well as features and functionality not available without the computer. For example, if
theLatticesystemislinkedtoanofficenetworkitispossiblebymeansofaprocessknownas“remoting”
to use networked computers to access certain functionality. A security guard could have a PC in his
guard house, and each time a tag is presented at the entrance, a photograph of the tag's correct owner
would flash up on his screen as confirmation that the tag is being used by the correct person. (For full
details,seetheseparateinstallationmanualfortheLatticeWaresoftwaresystem).
The Lattice Ware system uses the freeware Firebird database which needs no license. Other databases
suchasMySQLcanalsobeusedifrequired.
All of the readers operate on the new 13.56 MHz RFID norm which is likely to become the benchmark in
the future. This standard means tags are relatively inexpensive, give good read ranges and can offer,
optionally,read-writecapability.

Both flush and surface mount readers are available. The flush mount unit fits perfectly into a standard,

The word “proximity” means “close to” or “near”. Thus a tag has only to be brought “near” or within a

The system uses RFID (Radio Frequency IDentification) technology. The reader has an antenna which
sends out a weak radio signal. The tag also has an antenna (a small coil) that receives the reader signal
as soon as it is in range. The tag absorbs some of the energy from the reader signal and powers up the
electronic circuit on the tag. There is no battery in the tag and it is thus known as a “passive” tag. An

Network: AnetworkisdefinedasasingleL1000anditsTUHandLSH's.
Area: An area is a physical area in which personnel work, or into which, or through which, they move.
E.g. Sales area, passage, classroom, etc. It is possible to have infinite areas at a site, but access to only
16 can be effectively controlled with the L1000 system. (The L1000 has a maximum of 32 readers split
between16entrance,and16exit,readers)
Zone: A zone is defined as an area, (or areas), which form a security level (or hierarchy). Thus, it is
possibletomovethroughseveralareas,butremaininthesame zone.Only7 differentzonesare allowed,
but each tag (or user) can have its own series of zones associated with it. Thus an entrance lobby,
passage and office 1 could be defined as zone 1 for user 1, whereas the entrance lobby and passage
couldbezone1foruser2,andoffice2mightbedefinedaszone2. Anti-passbacklevels(definedbelow)

The Lattice Ware system uses the freeware Firebird database which needs no license. Other databases
suchasMySQLcanalsobeusedifrequired.
All of the readers operate on the new 13.56 MHz RFID norm which is likely to become the benchmark in
the future. This standard means tags are relatively inexpensive, give good read ranges and can offer,
optionally,read-writecapability.

Both flush and surface mount readers are available. The flush mount unit fits perfectly into a standard,
wall-mounted,light-switchbox.

The word “proximity” means “close to” or “near”. Thus a tag has only to be brought “near” or within a
certainrangeofthereaderbeforeitisread.Thereisnophysicalcontactbetweentagandreader.Theread

The system uses RFID (Radio Frequency IDentification) technology. The reader has an antenna which
sends out a weak radio signal. The tag also has an antenna (a small coil) that receives the reader signal
as soon as it is in range. The tag absorbs some of the energy from the reader signal and powers up the
electronic circuit on the tag. There is no battery in the tag and it is thus known as a “passive” tag. An
“active”taghasabatteryandisusedinapplicationsrequiringgreater“read”ranges.

The reader receives the signal and checks to see if the tag serial number is one that is stored within its

Basic concepts
BeforedescribingtheL1000systemindetailsomebasictermsandconceptsareexplained.
L1000Controller:The“Master”controllerinthesystemwhichcanbeusedasastandalonereaderhead,

Lattice slave head (LSH): A Lattice slave head is an auxiliary head that must be networked to a L1000
Controllerheadusing a RS485network. Up to31LSH'scanbe linked toasingleL1000. Aremoteslave

“supervisor”tagsinanoff-linesituation.
Take up head: A tag readerwhich also creates the interfacebetween the L1000 and acomputer running
LatticeWaresoftware.
Site: A site is defined as the geographical area where the L1000 access control system is located. E.g.
BryanstonSchool,DurbanBranchoffice,etc.
Network: AnetworkisdefinedasasingleL1000anditsTUHandLSH's.
Area: An area is a physical area in which personnel work, or into which, or through which, they move.
E.g. Sales area, passage, classroom, etc. It is possible to have infinite areas at a site, but access to only
16 can be effectively controlled with the L1000 system. (The L1000 has a maximum of 32 readers split
between16entrance,and16exit,readers)
Zone: A zone is defined as an area, (or areas), which form a security level (or hierarchy). Thus, it is
possibletomovethroughseveralareas,butremaininthesame zone.Only7 differentzonesare allowed,
but each tag (or user) can have its own series of zones associated with it. Thus an entrance lobby,
passage and office 1 could be defined as zone 1 for user 1, whereas the entrance lobby and passage
couldbezone1foruser2,andoffice2mightbedefinedaszone2. Anti-passbacklevels(definedbelow)
operatebetweenzones.

Anti-pass back (APB): In general terms, this is a technique where a tag used at an “entrance” reader
cannot be re-used at that same entrance reader until it has been presented to an “exit” reader. Thus the
tagcannotbe“passedback”toafriend!
Structuredanti-passback: Structuredanti-passbackmeansthatareaderwillalwayscheckfortheAPB

(i.e. going from higher to lower security level) the reader will permit exit without forcing a level by level
reduction. This is a type of free-exit facility. This provides for more flexibility of personnel movement
through various exit readers, but still provides the security that staff cannot gain access to unauthorized
areas.

The reason for an ID is that although every single tag has a unique serial number it is not possible to

It is preferable to have only one tag associated with each ID as this ensures that tags can be uniquely
identified. In some cases, however, there may be a requirement to allocate multiple tags to a single ID.

E.g. it may be sufficient to allocate all sales staff (say five people) to ID=001, all factory workers (say 15
people)toID=002,andallgeneralstaff(say5people)toID=003. Thereareactually25tagsbeingused,
