Installation Notes on Keypads
Do not run keypad cables in same conduit with AC power or signal cables.
Keep keypad 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 keypads 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.
Important
Keypads made by other manufacturers may not have the necessary Wiegand interface. Hence, these
keypads will not operate in dual card and PIN modes; they will only operate in card/reader simulation.
