PARA Dox CR-R880-BL, Installation Manual

CR-R880-BL 7

Mounting on Metal

Although metal may decrease the read range, the CR-
R880-BL card reader can be mounted on metal. 
However, do not box in or surround the card reader with 
any kind of metal. If the reader must be installed in a 
metal enclosure, ensure that the face of the card reader 
is not covered and that there's at least 4cm (1.6") 
between the card reader and the metal on all sides of the 
card reader.

Wiring

Using the recommended cables listed in the technical 
specifications on page 3, splice these cables together 
with the pigtail of the reader and seal the splice. Route 
the cable from the reader to the host controller. Do not 
wire the CR-R880-BL cables in the same conduit with AC 
power cables, lock power, or signal wiring. Maintain all 
reader wiring a minimum of 30cm (12") away from other 
wiring such as: AC power, computer data wiring, 
telephone wiring, wiring to electric lock devices, etc. 
Connect the cables as shown in Figure 2 on page 10 for 
Wiegand connections, or Figure 3 on page 11 for ABA 
connections. Trim and cover all conductors.

Important Installation Notes

Do not connect the shield wires together at 
the reader cable splice. With the shield wire 
already terminated at the reader, simply 
terminate the shield at the controller. Do not 
connect the shield to the black wire at the 
reader cable splice. (refer to Figure 2 on 
page 10 and Figure 3 on page 11).
