Wiegand Readers

There are three types of Wiegand card readers:

Swipe reader, through which a card is passed

Insertion reader, into which a card is inserted and removed

Key reader, into which a key shaped card is inserted and removed

A sensing coil inside a Wiegand reader creates a magnetic field. When the

wires inside the card interact with the magnetic field, they create low

voltage impulses in the coil. Depending on the arrangement of the wires

in the card, the voltage is either positive or negative. The personality

module translates the impulses and transmits the information to the apC/L

for processing.

Each swipe, insertion, and key Wiegand Reader has a single bi-colored

LED which indicates the status of the door. Sensormatic RM Wiegand

readers have a 3 LED display.

Proximity Readers (Also uses Wiegand format)

The proximity reader transmits a radio frequency signal. A proximity card

is a radio frequency transponder, or tag, which consists of an antenna coil,

and an integrated circuit chip encoded with a unique identification

number. When a card is passed near the reader, it energizes the card’s

antenna, causing it to send its identification number to the reader. The

card and reader do not make physical contact. LED indicators for

proximity readers vary according to manufacturer.

The Auxiliary Relay Module

The Auxiliary Relay Module, or ARM-1 (part # 131-912), is an optional

relay module that takes a logic-driven signal from the reader and drives or

switches a 12/24V relay for the door strike or for other use. The ARM-1 is

1.7” by 0.75” (4.3 by 1.91 cm) in size. It is mounted inside the protected

area no more than 25 feet (7.6 m) from the RM. The ARM-1 contains 1

Form C relay capable of driving a 30V, 2A non-inductive or 1A inductive

load.

Note You can connect two ARM-1 modules to each RM-4 module.
