This section describes the ideal locations to mount the WRI-OTD and WPIM to control a typical
cabled hoist elevator (Figure 2-2) or a typical hydraulic elevator (Figure 2-3).
Figure 2-2 – Cabled Hoist Elevator Installation
2.3.2.1 Cabled hoist machine installations with upper machine rooms (Figure 2-2)
Mount the WPIM inside the secured portion of the premises. For example, mount the WPIM
within the secured elevator machine room, and mount remote WPIM antenna inside the shaft, on
the ceiling of the shaft. Keep in mind that the remote antenna has a cable length of 15 feet, so
locate the WPIM enclosure so that the antenna cable reaches. Mount the assembly such that the
WPIM antenna has a direct line of sight to the WRI-OTD throughout the entire shaft. No
structural members should obstruct its view to the WRI-OTD.
Mount the WRI-OTD on top of the cab, lying down if possible (Figure 2-2).
2.3.2.2 Cabled hoist machine installations with lower machine rooms (Figure 2-3)
If the machine room resides at the bottom of the shaft, install the components per section 2.3.2.3,
like hydraulic machines. Use the Remote Antenna Module with the WPIM to prevent
contamination of the WPIM from settled dust, oil, and debris.
2.3.2.3 Hydraulic Machine Installations (Figure 2-3)
Locate the WPIM enclosure in a secured area of the premises, outside of the shaft pit, where it
will be free of contamination from oil. Use the Remote Antenna Module with the WPIM. Mount
the Remote Antenna Module horizontally in the shaft pit, at a height where oil leakage and
debris cannot submerge it. For reliability of communications, the Remote Antenna Module must
have a direct line of sight to the WRI-OTD throughout the entire shaft. No structural members,
including the ram, should obstruct its view of the WRI-OTD.
Mount the WRI-OTD on the underside of the cab.
