Installing the Reader
Choose the Best Mounting Location for the User
The normal height for the reader is approximately 48 inches (four feet) from the floor, on the
unhinged side. Check local regulations regarding proper mounting locations for disabled or
handicapped persons.
Mount the reader on any firm flat surface. Avoid mounting the reader on rough textured surfaces.
There must be a distance of at least 36 inches (three feet) between two readers. Therefore, if
using readers to control entry and exit from an area, they must be mounted on opposite sides of
the door.
No special precautions are needed if the reader is mounted outside, as it is fully encapsulated. The
connections made to the flying lead, however, may need protection.
Route the Cable
Install the reader up to 200 feet from the Control Panel or Wiegand Interface Unit using 22 AWG
wire or up to 500 feet using 18 AWG wire. Run a five or six wire cable from the controlling unit to
the reader mounting location.
Protect the reader cable from EMI:
Do not route the reader cable close to the power lines for
the electric lock. Use shielded cable to eliminate possible interference to the data from the electric
lock.
Splicing the Cable to the Wiring Harness
Use the crimp connectors provided, or other suitable means such as soldering, to splice the wiring
harness, provided on the reader to the end of the cable. When using 22 AWG cable, you should
twist the wires together and double them over before inserting them in the crimp.
