Hardware #

The following diagram provides a high-level overview of the Access Control hardware arrangement

An Axel Terminal Server provides a network connection to the access control solution – this needs to be located within close proximity of the Master Access Control Box. The will be one of these per floor enabling two master modules per floor plus 31 slaves per master (this provides a total capacity of 64 readers per floor).

An RS232 cable links the Axel Terminal Server to the Master Control Box – this can use cat 5 cabling if over a short distance and terminated at both ends so that short cat5 patch leads can be used with special DB9 RS-232 headshells (ESP supply these headshells – you supply the cables!)

Master Modules – this is the first Nortech control box which may have a card reader attached, or can simply act as the first point for the cable to run to the subsequent slave. An RS-485 cable is run to each slave in turn in a daisychain format. This cable is a Belden 9729 or equivalent cable with a maximum TOTAL distance of 1200m.

Slave Modules – there can be up to 31 slaves connected in line. Each slave unit is assigned a unique node number (2-31)

Nortech Control boxes may contain one, two, three or four modules – the first will become the master and subsequent ones are slaves. Each module controls one reader and provides the control outputs for the associated door, turnstile or barrier. It also supports a ‘Free Exit’ push button.

Dependent on the location of each access control point (e.g. door) will determine whether a single, double, triple or quad module box is used – the rough rule of thumb is that each box should be no further than 2.5 metres from the reader’s location.

ESP’s Hardware #

Nortech DeltaQuest. Control Boxes

Typical view of control box – all control units come as a 2 reader interface.

Each box requires a Fuse Spur for the mains supply – ESP will supply the boxes but DOES NOT mount them or connect them to the Mains Supply.

Belden 9729 or equivalent cable links each module in line – this cable must be run from the last module of each control box to the first module of the next box.

Idesco Card Reader

These are wall mounted for customers to present their cards / bands to gain access – a fixed cable from the back of the reader runs to the Nortech Control Box.

These readers have a standard 3m cable: a Belden 9538 or equivalent (10m max) can be used to extend from Nortech Control Unit to location of each Idesco Card Reader – this must be a single run of cable with NO JOINS to each reader location.

Below is a schematic of how multiple boxes are linked together

Control Box Relay & Exit #

Each module has a relay to be able to control locking mechisms such as magnets or turnstiles. Each box has a 12V 3A PSU for driving card readers and associated locking hardware such as door latches or magnets – dependent on the load, there MAY be a requirement for a separate PSU for your locking hardware.
