COMPONENT INSTALLATION

7 Component Installation

7.1 Basic Component Installation

The PIV-Station readers do not have built-in relays that would allow them to control a door lock, and therefore,

they must be part of a larger access control system. System component selection is very specific to each

installation but a minimum system would consist of a finger-scan reader mounted on or near an access point, an

electric lock, cabling, and the access controller. More complex systems might consist of readers on multiple

access points, each with an electric door lock, a multi-point controller, networking and a PC to run the access

controller and VeriAdmin Management Software. See Figure 3 below for an example (not for Ethernet).

The installation of the locks and access controllers should be completed according to the manufacturer’s

specifications and in accordance with all local codes. Final connections to the PIV-Station will be covered in

more detail later.

Wiegand, RS-232, and power cabling for the system are minor aspects to the installation, requiring nothing

more than planning the cabling route and pulling the cable through the building. It requires only that one is

familiar with basic electrical installation theory.

Do not run any wires near utility AC power wiring, lightning rod grounding wire, and etc. to avoid externally

generated transients. Grounding equipment is required for ESD protection and safety.

7.2 Choosing a Network Type

If your installation requires the use of network communications, then the choice of cable, the cable run length,

the network topology, and termination of the network are very important aspects that must not be overlooked.

Table 1 outlines the relevant differences between an RS-485 and RS-232 communications. If your system has

one or a few readers each only a short distance away from the VeriAdmin PC then RS-232 could be used

providing that each reader can have a dedicated RS-232 port.
