Section 1: Introduction
The PC4820 is a versatile Dual Card Reader Access Control
module which will enable you to meet the most demanding
access control requirements of an installation. The PC4820
is monitored and programmed via the PC4010/4020 control
panel. Up to 16 PC4820 modules can be connected to a
PC4010/4020 via a 4-conductor Combus, using standard,
unshielded station wire.
Each PC4820 is capable of providing supervision for two
door inputs which may to assigned to any PC4010/4020
zone. Each door contact may be configured for any zone end
of line option which the control panel can provide.
Each of the two PC4820 Access Card Readers can be pro-
grammed to function independently on different doors, or
together controlling access for both sides of one door.
Control of the access points can be performed using a variety
of equipment. The PC4820 supports four different types of
card readers: the Polaris magnetic stripe reader, the Shadow-
Prox proximity card reader, the HID proximity readers, and
26-bit standard Wiegand card readers. The PC4820 also sup-
ports the use of any request to exit device including the T-
Rex exit detector.
