General Lock Helix 100: Stand-Alone Fingerprint Door Security

Designed to operate in outdoor and indoor applications, the Helix 100 can be used to control virtually any electrical device including lighting, switching and security systems.

The world of electronic security is constantly changing. The credentials used to access a system include swipe cards, insertion cards, proximity cards, proximity badges, proximity fobs, I-buttons, keypads (from 5 to 16 buttons) and biometric devices.

Biometrics is the use of human biology combined with a switching device. Today’s choices range from voice recognition to retina scanners and hand geometry readers to face recognition, but fingerprint readers continue to be one of the most accepted forms of biometrics.

Distributed exclusively by the nationwide network of Clark Security Products locations, the latest new product from General Lock is the Helix 100-fingerprint access controller. Designed to operate in outdoor and indoor applications, the Helix 100 can be used to control virtually any electrical device including lighting, switching and security systems.

The fingerprint sensor uses a radio-frequency technology penetrating below the skin to read even damaged or dirty fingers. The Helix can operate either completely standalone, with internet/web access, running a Windows™ interface, or any combination of these.

In standalone mode, all functions are controlled at the reader. The optional use is for the unit to be networked for multiple doors to a computer for instant network-wide finger enrollment and audit logs. The network setup provides full customization of the system.

In a situation where dual confirmation is required the Helix can be integrated with an exit button, alarm or door controller or card reader. The system can be programmed to require either fingerprint only, card/pin only or both to gain entry.

The Helix 100 comes in a kit that includes the Helix 100 in black or silver housing, metal mounting back plate/bracket, door strike power cable (red/black), 2 cable assemblies (BRS-819-32-3/5), software on CD-ROM, secure I/O electronics board (SIOB) screw pack – including security screws, security Allen key, wall plugs, wall mounting screws, sealing grommet, and diode and quick install guide, including a helpful section on troubleshooting.

Determine the mounting position for the Helix 100. If installing in a network setup, verify available reach of network cable. Install the housing metal bracket on a flat surface on the external side of the door. Suggested height is about five feet from finished floor. Drill mounting holes for bracket and pass through hole for wiring harness according to the instructions. Pull the cable through the wall with the small 10-pin white connector coming through the hole. Position the rubber grommet around the pass through hole to protect the wiring. Verify that no wires are crimped or damaged during installation.

The SIOB secure I/O board should be installed on the secure side of the door ,inaccessible from the public. Typical location is a wall cavity, small key cabinet or ceiling space above the door. Connect the white cable connector to the Helix 100 unit with the blue wire towards the top and gently bring the housing to the back plate. The housing mounts to the plate five degrees counterclockwise from vertical. The slight rotation will ensure a proper seal on the outer unit. Push the Helix 100 shell and rotate clockwise until the security screw hole lines up in the metal back plate. Insert the security screw and tighten.

Install the door strike or electronic lock in the normal fashion. Run the figure-8 red/black cable from the I/O board to the connection points of the door strike. Install the spare shunt diode supplied with the kit in parallel with the door strike to prevent damage to the SIOB or Helix 100. The secure I/O board is used to control the electric strike/lock and also connects to the Weigand devices (alarm and access control systems). The SIOB is connected to the Helix 100 via 4 wires marked Vout, GND, 485+ and 485- in the cable BRS-819-32-3/5. Connect the wires to the strike cable and power adaptor as indicated in the supplied wiring diagram.
Alarm and access control systems connect to the SIOB with a shielded cable (not supplied) to the W0, W1 and GND screw connections. For EX or Weigand input functions, connect as indicated in the supplied wiring diagram.

Turn on the power. If properly connected, the Helix 100 green LED will stay on for about 20 seconds, the Red, Green and Blue LEDs will cycle a few times then the Blue LED will stay on. This indicates the unit is ready for programming.
