Specifications:
Cable Requirements: 24 AWG minimum, multi-conductor stranded with an overall foil shield, for example Belden 9540 or similar. Per the SIA’s Wiegand specification, maximum cable length is 500 feet (152.4 m)
Grounding: Shield (drain) continuity must run from the Receiver to the access panel. Shield and reader ground must be tied together at the access panel and connect then to an earth ground at one point
Power: Power required is 12 VDC nominal at 120mA. The Receiver may be powered by the access panel. A linear power supply is recommended for best operation
Mounting: The Receiver may be mounted indoors or outdoors. The base of the enclosure includes a drill template providing mounting provisions to a wall box (standard North American and European), as well as pre-drilled holes in the four corners allowing mounting to a flat surface
Read Range Adjustment: As shipped, the Receiver is set for the maximum read range, which is nominally up to 500 feet. This may be reduced by adjusting the range pot in the counter-clockwise direction
Additionally, for optimal read range it is important that the Receiver be mounted as far from potential interference sources as possible
These sources may include, but are not limited to, large metal obstructions, as well as magnetic fields and radio transmissions. Note for each installation, read range may vary
External LED Indicator: Green: Initial power up Amber: Normal powered on state Flash Green: An activated Transmitter button press has been received and processed Flash Red: A non-activated Transmitter button press has been detected Off: Receiver is not powered on, or failed to power up successfully
Antenna Switch: As shipped, the Receiver’s Antenna Switch is set in the INT position. If a separate antenna is to be used, then the switch should be set in the EXT position
Beeper Switch: As shipped, the Receiver’s Beeper Switch is set in the ON position. If the installation technician prefers to disable the beeper and External LED Indicator, then the Beeper Switch should be set in the OFF position
Connections: 10-Pin Terminal Block - Refer to the information below for cabling to the Receiver:
