eAC System components are designed to meet the requirements for Class 2 circuits operating from a

non-hazardous secondary power source limited to 240 VA. Cabling materials must be selected for the

installation environment in accordance with the applicable jurisdictional codes.

2 INSTALLATION

MOUNTING INSTRUCTIONS

The Controller chassis may be horizontally or vertically mounted on a wall, ceiling, or shelf as long as the

front face panel is easily accessible. The RX antenna should be positioned on a vertical plane for

maximum performance.

The detection field radiates from two internal orthogonal ferrite cored inductors. The field must fill the

area in front of the door all the way to the floor so that no Tag can reach the door without being detected.

RECEIVER SENSITIVITY

The UHF Threshold control may be adjusted to increase or reduce the range of detection of the UHF

transmission of the Tags. Threshold adjustment removes some of the background noise, and reduces

interference from Tags not within the field of the Transceiver.

Initially decrease the threshold (CCW) until the UHF RX indicator flashes occasionally. This will establish a

threshold sensitivity to background noise at the door site. Using the RF Test Tag in the keyed mode,

reduce the receiver sensitivity (increase threshold CW) until the RX indicator becomes intermittent at 25

to 30 feet. Reduce the threshold slightly and walk the tag around the area of coverage to check for

consistent UHF reception.

LF FIELD ADJUSTMENT

Adjust the LF Field for a compromise between maximum desired tag detection range and the potential to

excite tags in adjacent rooms or floors. Note that the LF field tends to be omni-directional. Starting with

the field adjustment at maximum (full CW), walk the RF Test Tag around the area of desired protection.

Reduce the field until inconsistent tag identification occurs in parts of the coverage. (The UHF Threshold

adjustment should be increased to check that the eLink is not being limited by the UHF link.) Increase

the field strength in small increments until consistent detection results within the desired area of

detection.

FCC Regulations

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) This device may not cause harmful interference, and (2) This device must accept any interference

received, including interference that may cause undesired operation.

This equipment has been tested and found to comply with the limits for Class B Digital Device, pursuant

to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful

interference in a residential installation. This equipment generates and can radiate radio frequency

energy and, if not installed and used in accordance with the instructions, may cause harmful interference

to radio communications. However, there is no guarantee that interference will not occur in a particular

installation. If this equipment does cause harmful interference to radio or television reception, which can

be determined by turning the equipment off and on, the user is encouraged to try to correct the

interference by one or more of the following measures.

• Reorient or relocate the receiving antenna

• Increase the separation between the equipment and Receiver

• Connect the equipment into an outlet on a circuit different from that to which the Receiver is

connected

• Consult the dealer or an experienced radio/TV technician for help

Any changes or modifications not expressly approved by the party responsible for compliance could void

the user’s authority to operate the equipment.
