Introduction
This manual is an installation guide for the GE Models 940, 941,
970, 971, 972, and 973 proximity readers. Throughout this guide,
the abbreviation 94x represents reader models 940 and 941. The
abbreviation 97x represents reader models 970, 971, 972, and
973.
The 94x and 97x readers while similar in functionality offer a
variety of features making them suitable for different
applications. The 94x and 97x readers are designed to mount on
standard U.S. gang boxes. The 94x readers are single-gang box
size. The 97x readers are sized for larger dual gang box
installation, offer greater badge read range, and a keypad option.
Models 940 and 970 give the greatest all-around badge read range
for their respective sizes, making them ideal for most
installations.
Models 941 and 971 are tuned for installation on metal mounting
plates. The standard metal mounting plate shields the reader from
the effects of a metal wall, which would otherwise dramatically
reduce the read range. The optional back-to-back metal mounting
plate shields the reader from the effects of a metal wall and makes
the reader unidirectional; ideal for direct back-to-back reader
installations.
Models 972 and 973 are dual gang size readers, identical to the
970 and 971 respectively, except for their built-in twelve-position
keypad. This feature makes these readers ideal for installations
requiring keypad PIN entry in addition to a valid badge read.
