3. Splice reader wires and mount both readers
Position the reader at the appropriate
mounting position on the doorframe. To
comply with the Americans with Disabilities
Act (ADA), readers should not be installed
higher than 48” from the ground.
Pull the shielding off both the reader cable
and the wiring pigtailed through the drywall.
The EMC only requires five wires from the
reader to operate. Review the directions that
are supplied with the reader, but the following
rules usually apply:
PWR = red
wire
DATA 1
= white wire
DATA 0
= green wire
RTN = black
wire
LAMP = brown wire
Note:
Check the instructions supplied with
the reader for LED wiring. LED wire color will
vary by reader manufacturer. Also, all LED
functionality must comply with ADA
requirements (e.g., when the EMC grants
access and unlocks a door, the reader’s
green LED must remain lit for the duration of
the unlock cycle).
Figure 10: Wiring a Reader
Splice the wires together and secure using wire nuts or splice caps.
Be sure to cut back drain wires and tape back along with non-used reader wires (see Figure
10).
Drain wire (shield) should be connected at earth ground at the EMC (refer to Figure 6 on
page 10).
Position the reader against the wall. Use a level to assure that the reader is mounted
straight. Mount the reader to the wall using mounting hardware appropriate to the specific
material and type of construction of the wall.
4. Splice and mount the door hardware:
The proper placement and connections for your door hardware depend on the type of equipment
being used. Follow the instructions included with the door hardware on the best way to splice and
mount your hardware. Remember to install your transorb, diode, or MOV at the door lock location
for surge protection.
5. Wire door hardware to the power supply:
Follow the instructions included with the power supply for proper connection of locking hardware.
Follow the same procedure for the other door components (REX, PIR, etc.) that will be used.
