NOTES: 1. While this application note describes specific examples that use a WRI at the access point to control a gate, RF Repeaters can be used to extend the RF range and control any Schlage Wireless Access Point Module: WA5200, WA5600, WA993, WPR, WR!, or WSM. 2. This application noted mentions RF Channel number only as an example. Actual RF channels used should be based on application and environment requirements and conditions. 3. With the exception of Figure 5, the figures used in this application notes are block diagrams intended to show a top level view. They do not show the orientation of how the actual Wireless Access products are to be mounted. Refer to the specific Wireless Access products’ installation manuals for mounting instructions. 4. This application notes does not address using any Wireless Remote Antennae. Wireless Remote Antennae can also be used with Wireless Access Repeaters to improve and increase RF coverage.

Using a Schlage Wireless Access RF Repeater to Increase Range
Introduction: A standard PIM & WRI configuration is shown in Figure 1. This configuration allows for the Panel PIM and Access Point WRI to be up to 200’ apart inside a building and up to 1000‘ apart line-ofsight.
Figure 1 – Standard PIM/WRI Block Diagram A RF Repeater is a device that receives information on one RF channel and retransmits it on another RF channel. Each RF Repeater can increase the RF range by up to 200’ indoors or up to 1000’ line-of-sight. Multiple RF Repeaters can be used in series to increase the RF range even further. A Schlage Wireless Access RF Repeater can be constructed by wiring a WRI-OTD-12VDC and PIM-TD2 together (Figure 2). Local power will have to be supplied to operate the RF Repeater (12 VDC at 600 mA). The use of multiple RF Repeaters in series and proper management of RF channel usage will allow the RF range to be increased indefinitely.

Using a Schlage Wireless Access RF Repeater to Increase Range
Example 1: Suppose you want to control a gate from an access control panel inside the building and that the gate is 1,000 feet from the building. In this case, you can either mount the PIM outside or use a remote antenna. Each of these solutions requires the making of a hole from inside the building to outside. By mounting a RF Repeater on top of the building it can talk directly to the gate at 1,000 feet and also talk to the panel PIM located inside the building within 200 ft of the RF Repeater (Figure 3). The only rule is that each PIM (panel and repeaters) be operating on a different RF frequency. In this case, the RF Repeater PIM could be on channel 8 and linked to the Access Point WRI at the gate and Panel PIM could be on channel 9 and linked the Repeater WRI.
NOTE: Each PIM/WRI RF channel must be linked separately! Figure 3 – Using One RF Repeater (Example 1) Example 2: Suppose, like in example 1, you want to control a gate but the distance between the gate and building is 5000 feet. Accomplish this by adding on to example 1: ♦ Add four (4) more RF Repeaters ♦ Keep each RF Repeater in line-of sight of the PIM and WRI that it must communicate with ♦ Local power must be provided at each RF Repeater location Now this gate can be operated from a distance of 5,000 feet from the building (Figure 4)!! Let’s review the RF channel management; The Panel PIM is on channel 9, Repeater PIM #1 is on channel 8, Repeater PIM #2 is on channel 7, Repeater PIM #3 is on channel 6, Repeater PIM #4 is on channel 5, Repeater PIM #5 is on channel 4. Repeater PIM #5 is linked to the Access Point WRI at the gate. We used 6 channels to cover 5,000 feet plus the distance from the panel PIM to the first repeater. Note: While in theory there is not a limit on the number of RF repeater that can be used, practically each RF Repeater can add up to 250 mS delay before the WRI at the gate receives an access grant to open the gate. This overall time delay must be taken into account when configuring all the WRI’s used in a repeater configuration (i.e. adjusting the setting of the WRIs’ First, Delay, and Retry configuration items). This example of using 5 repeaters could add up to 1.25 seconds delay. Ingersoll Rand Security Technologies 245 W.

Example 3: The first two examples were for outdoor applications but the same techniques can be used to extend coverage indoors. Simply follow the process indicated above but use a distance up to 200 feet (depending on the type of construction). Installing and Wiring the Schlage Wireless Access Repeater: Use the PIM-TD2 and WRI-100 Installation Manuals to mount the Repeater PIM and the Repeater WRI in their desired and RF optimal locations. Use Table 1 to wire DC power to the Repeater WRI and to make the required wiring connections between the Repeater WRI and Repeater PIM. Use wire that meets or exceeds the specifications detailed in the PIM and WRI Installation Manuals. NOTE: Do not use the wiring instructions in the PIM & WRI Installation manuals. DC Connections

Special Considerations: WRI Configuration: The Repeater WRI should be configured with the default settings as shown in Table 2 using the Configuration and Demonstration Tool (CDT) available at www.ir-swa.com. Referring to Table 2, the Heartbeat, First, Delay, and Retry items may need to be adjusted based on the number of repeaters in the RF transmission path. This is discussed in the following sections.

Table 2 – Repeater WRI Configuration Settings Heartbeat Time: Typically there is no need to be concerned about “Heartbeat.” However, if you want something to happen quickly upon a command from the panel, the heartbeat may have to be adjusted to a few seconds. This is not a problem as each “Repeater” has local power. First, Delay, & Retry: Each RF Repeater used increases the response time from card swipe to unlock by about 100 milliseconds. Depending on the number of RF Repeaters being used, the First, Delay, and Retry configurable items for each Repeater WRI and the Access Point WRI may have to be adjusted to make certain that the WRI’s are waiting long enough for a response from the Access Panel. If an access point is not unlocking or occasionally does not unlock even when the Access Panel has granted access, try increasing the Retry value of the WRI’s. The WRI’s closest (in RF path) to the Access Point will experience the greatest delay and therefore they would be the WRI’s to adjust first. Linking: Each PIM/WRI pair must be linked individually (i.e. Panel PIM to Repeater WRI, each Repeater PIM to Repeater WRI, and Repeater PIM to Access Point WRI). The order that they are linked is not important as long as they all get linked. Make certain that the PIM RF Channel Address DIP switch is properly set before linking. Use the linking procedure detailed in the WRI section of the Schlage Wireless Access Configuration and Operating Manual. When linking a PIM, make certain that the Door wired to the Access Control Panel or Repeater WRI is the Door that is being linked. In other words, if PIM Door A is wired to the Access Control Panel or Repeater Ingersoll Rand Security Technologies 245 W.

WRI then link PIM Door A. If PIM Door B is wired to the Access Control Panel or Repeater WRI then link PIM Door B,. Trouble Reporting: When using a RF Repeater, the Panel PIM LEDs and each Repeater PIM LEDs will indicate the trouble for the Access Point WRI or Repeater WRI to which it is linked. So if a trouble is reported to the Access Control Panel, each PIM (Panel or Repeater) may have to be inspected to determine the actual source of the trouble. Access Points: This application note describes only one access point being used per RF Repeater that uses the configuration shown in Figure 2. Each PIM has the capability to control up to two doors. While it is possible to link either another Repeater WRI or any other Schlage Wireless Access Point Module to a PIM, that configuration and application is outside the scope of this application note.
