Planning the Installation

Planning the installation is probably the single most important aspect to a

successful installation. Good planning will be comprehensive, accurate, and

adaptable. Planning for an Access Control installation must consider: the access

controller, the door locks, and the readers. Readers provide a means for the users

to request access to a controlled area. The Veri-Series products are different from

typical readers in that they provide not only verification of the presence of an

authorized card, but also the assurance that the authorized holder is presenting

the card.

During the planning phase, you should determine:

Ø How many doors need to be protected

Ø What type of reader on each door (maybe some doors are internal and

don’t require the added security of the Veri-Series)

Ø If multiple Veri-Series units are to be networked, a dedicated PC is

recommended to administer the system. This can be done through RS-232

(primary or auxiliary ports), RS-485, or via Ethernet (V-Station only).

Ø The controller must support any of the Wiegand formats supported by the

Veri-Series units.

Ø If the installation requires RS-485 or Ethernet network cabling for template

distribution/management

When planning the system, identify all wiring by the signal levels they are to carry.

Wires can be generally separated into the following groups:

1. Power distribution: Wires carry power to devices, door strikes, etc.

2. Data communication: RS485, RS-232, Ethernet, Wiegand, etc.

3. Sensor: Door contact, request to exit push button, alarm input, etc.

Use separate cable/conduit for different signal groups to avoid cross talk. Observe

the distance limitation of each type of signal when planning device placement.

Line extenders or repeaters can be used for extended distances when required.

Do not run any wires near utility AC power wiring, lightning rod grounding wire,

etc. to avoid externally generated transients. Grounding equipment is required for

ESD protection and safety.

Do research on the environment where the equipment will operate. If used

outdoors, it may be necessary to seal the readers or protect the installation with a

weather shield.
