Quick Install Guide
For experienced installers looking to do a basic installation and programming of the reader, but for in-depth installation and programming instructions, see Table of Contents on pg. 5

Quick Wiring Guide

NOTE: To protect the relay, you must install the enclosed diode—with the cathode (striped end ) toward the positive side—for DC powered locks OR install the varistor (MOV, not supplied) for AC powered locks and for electromagnetic locks unless your lock has a diode/MOV built in (all SECO-LARM electromagnetic locks have built-in protection). Do not install both diode and MOV. Failure to use these as directed will void the warranty.

Programming Tips

Master programming code (6 digits) should be programmed before any other programming.

A steady red LED indicates that the reader is powered on and ready. The LED will change to flashing red and a single beep will sound to indicate the device has entered programming mode.
A steady orange LED indicates that the reader is in a function programming mode.
Do not disconnect the reader from power while in programming mode. Doing so may cause a memory error.

Note that, in programming instructions, programming entry actions or options other than specific keystrokes are enclosed within the parentheses, while factory defaults are enclosed within square brackets.

NOTE: The alarm duration follows the overall setting (see Programming the External Alarm Output, ).
Exit programming mode: *

Setting Up a Two-Door Interlock System with Two Readers

In this application, two of the same series of readers are each connected to separate door locks and egress pushbuttons. While one door is open, the other cannot be opened.

Two-Door Interlock System Wiring Diagram

NOTE: To protect the relay, you must install the enclosed diode—with the cathode (striped end ) toward the positive side—for DC powered locks OR install a varistor (MOV, not supplied) for AC powered locks and for electromagnetic locks unless your lock has a diode/MOV built in (all SECO-LARM electromagnetic locks have built-in protection). Do not install both diode and MOV. Failure to use these as directed will void the warranty.

Programming the Interlock System

Enter programming mode: * (master code) #
Disable: 70#[default] OR
Enable: 71#
Exit programming mode: *
NOTE: While you may wish to do so for convenience, it is not necessary for the two readers to have the same master codes.

Setting Up the Wiegand Reader Mode

The reader can work as a standard Wiegand reader with a controller. Be sure to set the reader operation mode to Wiegand reader mode.

Enter programming mode: *(master code) #
Wiegand reader mode: 75#

Set PIN input bits: 8 (4 or 8 or 10) # [default: 4 bits]
Exit programming mode: *

Programming a Fingerprint from the Reader

To add fingerprints, the keypad must be in standalone mode: 74#
NOTE: This product can use fingerprints as a virtual proximity card, a Wiegand data stream to the Wiegand controller.
Enter programming mode: * (Master Code) #
Enable Device ID: 81 (01 ~ 99) #
Add fingerprint via user ID: 1 (user ID) # (fingerprint) (repeat fingerprint)
NOTE: User ID, any number 1~1000
Exit programming mode: *

Wiegand Data Transmission Format
A scanned finger or entered PIN becomes a Wiegand data stream to the Wiegand controller. The Wiegand controller interprets the Weigand data stream as a proximity card.

Fingerprint Example

Device ID:99
Fingerprint user ID: 3
Wiegand data sent to the controller: 099,00003

PIN Example

Device ID:99
User inserts PIN:
Wiegand data sent to the controller: 099,05555

NOTE: If a user enters a PIN of 5-digits or greater, the Device ID will be ignored.

Example 1

Device ID: 99
User inserts PIN:
Wiegand data stream sent to the controller: 000,55555

Example 2

Device ID: 99
User inserts PIN:
Wiegand data stream sent to the controller: 005,55555

Resetting the Reader to Factory Default
When resetting to factory default, user information is retained. You may also program new Master fingerprint. To reset the reader to factory default settings, follow steps 1~4 below.

Power off the reader.
Hold down the egress (Request-to-Exit, RTE) button and power the reader on, continuing to hold down the egress button until you hear 2 beeps and the LED turns orange.
NOTE: If no egress button is installed, use a small jumper wire to momentarily connect the yellow and black wires.
Release the egress button.
If you only need to reset the reader to factory default, wait until the LED changes to red (about 30 seconds) indicating that the reset has completed successfully.
If you need to program a new Master fingerprint, within 30 seconds scan the Master Add fingerprint twice, then the Master Delete fingerprint twice. The LED will change to red indicating that the reset has completed successfully.

Troubleshooting

Unit fails to accept a new fingerprint

Ensure the User ID assigned is between 1 and 1000
Ensure the User ID is not already assigned to another user

Unit fails to accept a new PIN

Ensure the User ID assigned is between 1 and 1000.
Ensure the PIN is between 4~6 digits long and not already assigned to another user.

Unit fails to read a programmed fingerprint

Ensure the finger being presented is the same finger that was originally programmed.
Press the finger evenly on the central area of the reader.
Ensure the reader window is clean.

Unit fails to respond to a programmed fingerprint or PIN

Ensure the unit is in standby mode by pressing the * key until the LED becomes steady red

User Operation of the Reader

Depending on access mode setup, to activate the relay, the user must either:

Present a fingerprint
Enter a PIN
Present a fingerprint + a PIN

The user should hear 1 beep and the status LED should turn green to indicate that the credentials are accepted, and the door is unlocked. Present a valid PIN or fingerprint to silence an alarm (except for duress alarms).

NOTE: An alarm (except duress alarms) can be disabled by a valid PIN or fingerprint (unless Access Mode is set to Fingerprint+PIN or Multi-User Access).
