Wireless TRACcess Interface (WTI) Retrofit
Installation Instructions
Figure 1. Bezel interface and Wireless interface
Installation
To replace the bezel interface with the wireless interface
(refer to Figure 2):
1. Remove the screws from the electronics enclosure lid
and then remove the lid.
2. Disconnect the wiring plugged in to the electronics
enclosure. Make careful notes of the connection pin-
outs as the exterior WTI interface retrofit plate will be
reconnected similarly.
3. Remove the four screws that secure the electronics
enclosure to the interior plate and remove the
electronics enclosure.
4. Remove the four screws securing the old bezel
interface plate to the interior plate. Remove the old
interface plate.
5.
Feed the four-wire plug from the retrofit plate through
the cabling hole in the door, and secure the interior
mounting plate to the retrofit plate (Figure 2). Insert
and tighten screws through interior mounting plate. For
1-1/4 to 1-1/2 in. (32 to 38 mm) doors, use 3/4 in. (19
mm) screws. For 1-1/2 to 2 in. (32 to 51 mm), use 1-1/4
in. (38 mm) screws.
Note:
If the screw does not fully secure the plates
to the door when tightened, use a shorter screw. Do
not overtighten the long screw.
6.
Feed the four-wire plug from the retrofit plate, and the
two-wire cable from the lockset through the cabling
hole in the electronics enclosure. You will attach the
wires after securing the enclosure.
7.
Use the four #8 × 5/16 in. (16 mm) pan-head screws
and lock washers to attach the electronics enclosure
to the interior mounting plate. Insert and tighten the
screws and lock washers securely.
8. Connect the two-wire cable and the four-wire plug
as they were previously connected in the electronics
enclosure.
