System 2 Installation / Programming Manual

Readers

Overview

Readers are designed to be flush mounted or surface mounted on a wall depending on the type used. They

have factory installed LEDS to provide the end user with visual feedback of the door/relay status. Mount the

Reader in a vertical or horizontal position. If the Reader is an outdoor version and will be mounted in a humid

location, protect the wire terminals from corrosion by applying a light coat of silicone grease or other protective

caulk to the terminals.

They may be installed in standard electrical back boxes (some Proximity or Data Chip models) or surface

mounted using standard electrical hardware. Bar Code, Magnetic Stripe and Wiegand Card Readers normally

supplied for the System are swipe-style, and are designed to be surface mounted. Swipe means there is an

open slot in the unit where the Card is passed through in a rapid fashion. It is "swiped" through the reader slot.

An insert reader is available for the Wiegand readers. Use the supplied mounting template, nylon or lead plugs,

and screws if mounting the Reader directly to the wall.

The standard Proximity reader is a surface mount reader with a read range of 5-8”. This reader is made to be

surface mounted, or hidden behind drywall. Switchplate Readers are indoor and designed to be mounted on a

standard wall box. Mullion readers are slim line and are designed to be mounted in a door frame.

Reader data is encoded making code duplication virtually impossible by shorting any of the data lines.

Status LEDS

Readers have a dual color LED that is normally red indicating that the reader is not active. When a valid Card

is used, the red LED changes its color to green for the duration of the door release time. It then changes back

to red when the "door open time" has elapsed or is canceled by a System "door closed" sense switch. When an

invalid card is used, the LED will blink four times to indicate that the card used was not authorized at that port.

If there is a wiring problem or parity error, the LED will blink twice.

Back To Back Readers

It is possible to install two readers back to back at the same door and connect both of them to one Port. It will

open the door any time a valid Card/Data Chip is used at either of the readers but the printer will only show the

Port used as a single Port. Of course, all other System data including the user ID and location will be recorded

and/or displayed.

To mount Bar Code, Data Chip, Magnetic Stripe or Wiegand Readers on both sides of the door, connect the

five wires together. These Readers will report as one. If you wish the Readers to report as a separate entry,

two Ports must be used - each wired directly to the system.

Back to back mounting of Proximity Readers is possible if done properly. Standard size readers cannot be

mounted directly back to back unless they are offset at least eight inches so that one is well outside the shadow

of the other.
