Linear WOR Specsheet

Wiegand Output

Radio Reader

Model WOR

TM

• Easy way to equip ANY Wiegand input access
control panel with radio transmitter access.

• Connects as easily as card readers;
transmitters are added like cards, with no
software changes required.

• Keyless entry offers user convenience, safety,
and security for triggering gates, barrier arms,
and doors.

• Ideal way to facilitate handicapped access.

• Multi-button transmitters can double as
personal emergency devices for triggering
security alarms.

• RF input/Wiegand output receiver supports
26, 30, or 31-bit data formats.

• Wide selection of MegaCode (over 1 million
codes) format transmitters, with available block
coding.

• Field adjustable read range—from 5 to to
500 feet.

• Facility and ID codes tailored to system
requirements.

• Weather-resistant case for mounting
outdoors or in.

Any existing access control system can
be equipped with radio-based proximity
sensing, by the simple addition of
Linear’s Radio Reader (Model WOR).
Keyless entry, handicapped access, and
emergency alert functions are easy
to achieve with this wireless control
technology.

With a read range of up to 500 feet, Linear
transmitters facilitate handicapped access far more than
close proximity or contact devices. For adding security
at sites such as college campuses and parking garages,
multichannel models allow access control and “panic
button” functions to be combined in a single device.

The WOR uses a Wiegand output format (26, 30,
and 31-bit supported) that interfaces to virtually any
commercial access control panel. Long-range transmitters
can be added as easily as Wiegand cards, and without
software changes. Facility and ID codes can be matched
to system requirements.

The 500 foot range of the WOR is made possible
by superheterodyne receiver technology. It is supplied
with a local whip antenna that screws directly onto
the receiver’s top connector. Two remote antennas
are also available: the directional EXA-2000 or the
omni-directional EXA-1000, both of which wire to the
receiver’s antenna connector with type RG-59 cable. An
integral gain control is included to limit the maximum
radio range that the WOR can achieve, if required.

A two-color LED acts as a status display. It lights
red when the receiver is getting dc power from the
system controller and turns green when access is
granted to a transmitter. The radio LED lights when the

receiver detects a transmission and can be used for

troubleshooting and verifying system
performance. Receiver test points are
provided for listening to incoming
signals.

The WOR is housed in a

weather-resistant enclosure, so it

can be mounted outdoors or inside.
Gaskets and a weather-tight wiring
strain relief seals the unit from the
elements.

General Specifications

RADIO FREQUENCY

Frequency: 318 MHz
Bandwidth: 300 KHz minimum
Image Rejection: 40 dB
LO Reradiation: 200 μV/meter @ 3 meters (maximum)
Data Format: MegaCode
Sensitivity: -100 dBm minimum
Sensitivity Adjustment: 20 dB variable attenuation at the

antenna input

INPUTS

Power: terminal block input “+” and “Gnd”; input voltage
operation 5 Vdc regulated or unregulated between +6 to +24
Vdc with reverse polarity protection

Hold: terminal block input “Hold”; follows standard Wiegand
hold line conventions; hold line can be
overridden via dip switch

Antenna: 9-1/2 in whip antenna with F-connector
(supplied)

Output Facility Code: 16 positions to select one of 65,536
possible facility codes; a selected output format may not use all
16 bits

Output Format: 3 positions for selecting either 26-bit, 30-bit,
or 31-bit Wiegand output format

Button Disable: 5 positions, each corresponding to 1 of 5
possible MegaCode transmitter buttons — left or top left, right
or top right, bottom left, bottom right, top

Receiver Lockout Disable: 1 position; if set to ON, the 1
second receiver lockout is not performed

Button Offset: 1 position; if set to ON, the transmitter ID
number is offset with a number based on which button
is pressed:

Button Offset
Left 0
Right 16384
Top 32768
Bottom Left or Right 49152

ENCLOSURE

Weather-resistant, anodized aluminum enclosure with
removable end caps to provide wiring and programming access;
end caps secured with screws

OPERATING TEMPERATURE

-22° to +155°C (-30° to +70°C)

OUTPUTS

Data: terminal block output “Data 0” and “Data 1”;
standard Wiegand electrical and protocol interface

LEDs: Red RF activity LED indicates RF activity at 318 MHz;
red/green decode LED is green during Wiegand
data transmissions and receiver hold timing window
(if enabled) after any output transmission, otherwise it is off
unless hold enable is selected, in which case LED
will remain red until hold is removed by host system

CONTROLS

Pushbutton: momentary switch labeled “Program” used to
configure microprocessor after system option selection and
configuration

Dip Switches:
Receiver Facility Code: four positions to select 1 of 16 possible

MegaCode facility codes; if code 0 is selected, the receiver will
validate any received facility code; any other selection requires
the transmitters’ facility code to match the receiver facility code
selection for validation

ELECTRICAL

Robust RFI and ESD protection for all inputs and outputs,
including antenna input; protection to prevent output errors
during brownouts

WIRING

Five conductor cable up to 300 feet, BELDEN 9929 or
equivalent (24 AWG); up to 500 feet, WEICO 9404 or
equivalent (20 AWG); up to 1,000 feet, CAT-5

AVAILABLE ACCESSORIES

Antennas:

a. EXA-1000: remote, omnidirectional; includes mounting

hardware and five feet of cable

b. EXA-2000: remote, directional-type; including

mounting hardware and ten feet of cable
