ProxLock

General Description

The ProxLock is a low cost stand-alone programmable access control system based on the GSC proximity tags.

The read-head, electronics, memory and relay circuitry are contained in a robust housing allowing for simple and quick installation. The minimum connection just requires 12V and a door strike.

The unit can store the codes of up to 2000 unique tags.

An optional transaction buffer module and WIN Software is available.

A Tag Simulator allows adding and deleting of tag numbers when the tag is lost.

For harsh environments a range of weatherproofed read heads (IP66) is available.

Specification

ProxLock Operation

Programming

The first tag presented to the reader will be stored in its memory and designated as the master tag. The master tag allows for programming of the following functions :

• Add Tags

  Every tag that is presented to the reader in the ADD state will be stored in the system memory and allowed access.

• Delete Tags

  When in the DELETE state all tags presented to the reader will be deleted from memory.

• Clear Memory

  The master tag allows erasure of all programmed data to reset the reader to the factory setting.

• Time Adjust (Strike time)

  This function sets the time the relay operates when a valid tag is read or the exit push button is pressed. The relay can be set to operate for any length of time between 0.25 to 12 seconds.

• Relay Operation (Pulse Mode and Toggle Mode)

  The relay on board can operate in Pulse Mode (suitable for access control applications) or Toggle Mode (suitable for arming/disarming alarms, switching lights, machines, etc.).

  Every time a valid proximity tag is read in Pulse Mode, the Green lamp will go on and the relay will operate, for the pre-set Relay Pulse time.

  Every time a valid proximity tag is read in Toggle Mode, the relay changes state. The RED lamp will be on when the relay is OFF and the GREEN lamp will be on when the relay is ON.

Remote Read Heads

The optional Remote Read Head is suitable for installations where a read head is required both sides of the access point or where the read head needs to be installed outside. It operates as a second reader point when connected to the ProxLock. The read head is tamper proof and can cope with extreme weather conditions. It is rated at IP66 and can be used from - 20° to +70°C.

Programming of tags can be performed at either the ProxLock reader or at the remote read head. For programming and operating purposes the remote read head has red and green LED indication.

The unit is ideally installed close to the ProxLock and is supplied with one metre cable. With a reduction in the tag reading range the remote read head will operate up to 10 metres from the ProxLock.


ProxLock Weatherproofing

A range of waterproof PVC housings (rated IP66) is available for installing ProxLock externally. Please consult your dealer for more information.

Tag Simulator (Optional)

The Tag Simulator is an extremely simple "Programming Device" that allows adding and deleting proximity card/tag numbers from the reader memory when the tag is lost or not available.

One Tag Simulator can be utilised at different sites - but for security reasons it will operate only in conjunction with the Master Tag.

Proxlog Transaction Logger and Win Reporting Software

An optional transaction logging module can be added to the ProxLock system. The logger dimensions are identical to the ProxLock unit.

The last 800 transactions are written accurately to the non-volatile memory of the logger. When the memory is full, new transactions overwrite the oldest ones.

The ProxLog Windows software offers a simple way to view and print card holders activities.

Specification

ProxNet

System Overview

ProxNet is an access control system based on RFID technology. The two main components of the system are the controller and up to 254 proximity readers and/or alarm monitor units. Optionally a PC running management and reporting software may be added to enhance the system. All communication is via a single RS-485 network.

The system supports up to 4000 card holders. The number of card holders can be increased if certain features are not used (by special arrangement with GSC only). Each card holder carries a uniquely encoded proximity card or tag, and presents this card to within some 10 cm of a reader to gain access via the associated door, turnstile, booth or boom. All readers are capable of making intelligent access decisions and logging transactions even if temporarily disconnected from the controller. The use of non-volatile memory in both the controller and readers ensures that no loss of data will be experienced during power failures.

The PC Windows 98/NT/2000/XP compatible software enables users to have total control of the system from his/her desk. The software is networkable and supports multiple users.

The drawing above shows some of the ProxNet components.

Access Levels

• Holders are assigned to one of 64 Access Levels.
• An Access Level is made up of a combination of any of the 8 time zones and 64 Areas.
• Time zones TZ1 - TZ7 are defined by a start time, stop time and valid days of the week.
• Time zone TZ8 is linked to the TZ8 switch input on the ProxNet Controller. Operation of this switch will bar all access except for those Holders set for TZ8 access.
• The access level tables are stored in the reader ensuring a secure system even if communications with the controller fail.

Anti-Pass-Back (APB)

If APB is implemented, a Holder will not be allowed access if their current area (stored in the controller) is the same as the area to which they are trying to gain access. This decision is made in the controller and if communications with the controller are lost, APB checks cannot be carried out until such time as communications are restored.

Three levels of APB can be implemented :

• Soft APB only checks when access movements are from a lower to a higher area (increasing area number) and ignore APB when moving from a higher to a lower area number.
• Hard APB checks all movements.
• Timed APB applies anti-passback for a defined period (e.g. 15 minutes) after the last movement.

Event Counters

Individual holders may be assigned an event counter which can be set to count up or down on each valid transaction.

The up counter may be reset to any value and will count up to a maximum count of 65535 after which the count will not increment. Access is still allowed after the maximum count is reached.

The down counter may be preset to any value up to 65535 and will decrease to zero after which the holder will be denied access.

Alarm Function

Each ProxNet Reader has an alarm input that may be wired to the internal tamper switch or to an external switch.

An alarm event at a reader operates and latches the alarm relay on the ProxNet Controller and is reset by the Alarm Reset push-button wired to the controller.

Alarm events are recorded as transactions with date and time.
