Installation Notes on Proximity Readers
Do not run reader cables in same conduit with AC power or signal cables.
Keep reader cables at a minimum distance of 12 inches or 30 centimetres from AC, computer data, telephone
data, or electric lock device cables.
Do not install readers within 3.5 feet or 1.1 metres of computer CRTs.
Do not install readers in areas where broad spectrum EMI noise may be present. Devices such as motors,
pumps, generators, and AC switching relays can create EMI noise.
Readers mounted on a metal surface can reduce the read range. See the Indala manual for recommendations.
