Mounting hardware (not provided), four ¼" diameter screws or bolts and/or anchors, type and length
of fasteners depend on the mounting surface.
2.2 Remote Antenna
If the WRI-OTD installation uses the Remote Antenna Module (RAM) option, please refer to the
"Remote Antenna Module Installation" manual before proceeding.
2.3 Determining the Best WPIM and WRI-OTD Locations
Proper selection of WPIM and WRI-OTD module mounting locations insures reliable RF
communications.
The WPIM manual contains a section for determining the best location for the WPIM.
The maximum distance between WPIM and a WRI-OTD is 200' horizontally when installed inside a
building on the same floor that uses normal building construction materials. Never locate the WRI-OTD
or RAM & WPIM & RAM more than one (1) floor apart. If on different floors, limit the maximum
horizontal distance to 100'. Do not locate on different floors if the building's floors use concrete over
metal construction. The maximum distance is up to 1000' for a line of sight installation using the internal
antenna. If an external directional 6 db gain antenna (ANT-REM-I/O+6DB) is used on either the WRI-
OTD or WPIM and properly aimed, then the maximum line of sight distance can be increased to 2000'. If
external directional 6 db gain antennae (ANT-REM-I/O+6DB) are used on both the WRI-OTD and
WPIM and properly aimed, then the maximum line of sight distance can be increased up to 4000'.
This section provides additional application specific help and guidelines to select the best mounting
location for the WPIM and WRI-OTD modules.
NOTE: A WRI-OTD located with a substantial steel barrier intervening between it and the PIM
may require alternate WRI-OTD and/or PIM placement in order to ensure reliable RF
communications. In these applications, mount the PIM remote from the access control panel.
Choose the PIM location to prevent "shadowing" of the WRI-OTD from PIM radio transmissions.
RAMs may be used to get over, under, through, or around obstacles with a limit of 15-20 cable feet
distance between it's WRI-OTD or WPIM and it's RAM.

Outdoor Gate Applications
This section describes the ideal mounting locations for the WRI-OTD and WPIM to control an
outdoor gate (Figure 2-1).
The WRI-OTD has not been evaluated to UL325.
