Signpost – Installation Manual and User Guide Guard RFID Solutions Inc. Page 2 of 7 Introduction Tag Reader is a device that is designed to operate in conjunction with a Tag and a Signpost. Basic Tag Reader functionality is shown in diagram below: The Signpost generates modulated RF signal at 125 kHz frequency, which is detected by the Tag. Upon detection of Signpost signal, the Tag transmits its own signal on 434 MHz frequency to one or more Tag Readers. Tag Readers process information and based on internal database, they activate outputs while simultaneously passing information to the Server computer which is running application software. There are two types of tag Readers: Tag Reader Door Controller and Tag Reader Receiver. Tag Reader Receiver is used when only to collect all the messages from the Tags and pass them toi the Server. Tag Reader Door Controller has the same functionality, but additionally, it is used for perimeter protection by controlling the door it is assigned to. Installation Position The main function of a Tag Reader is to receive RF communication from Tags. It is important to select carefully mounting location of the Tag Reader which will not interfere with a capability of the device to receive RF messages from the Tags. This is accomplished by avoiding mounting in the proximity of metal objects, cables, electrical devices, etc. Signpost 125 kHz Tag Tag Reader 434 MHz Ethernet Network
Signpost – Installation Manual and User Guide Guard RFID Solutions Inc. Page 3 of 7 Due to a nature of RF communication, it is hard to predict communication range between a Tag and a Tag Reader. This is heavily dependent on surrounding ambient, architecture, even people and equipment movement. However, in order to install the system, the assumption of certain communication range has to be made. To achieve complete RF coverage of a typical office style area (including typical healthcare facility), good starting point is to position Tag Readers in a grid pattern with 25-foot centers. During system testing this assumption may need some adjusting (accomplished by moving Tag Readers in either direction), but in majority of cases, it is proven to be a good general rule of thumb. Locations in which Tag Reader is shielded by metal tiles or walls should be avoided, or density of Tag Readers should be increased. Wiring Tag Reader requires 3 types of wiring to be fully functional: - Power Supply: o 12VDC power supply which is capable of delivering 0.3A of continuous current. AWG-18 or heavier wire should be used (depending on wire length). - Networking: o Ethernet CAT-5 cable with RJ-45 should be used for communication between a Tag Reader and the Server. - Peripheral: o This is applicable To Tag Reader DC only. It includes wiring for Door Switch Input, Bypass Input and Relay Output. Door Switch and Bypass Inputs can use AWG-20 or heavier wire, but Relay Output should use AWG-18 or heavier wire. All Tag Reader’s wiring connections are accessible without opening the enclosure. Configuration Tag Reader configuration is accomplished via 3-position DIP switch located inside the enclosure. The functionality of these switches is as follows: - Switch 1: Communication to Host disabled. o “0” Æ Communication enabled o “1” Æ Communication disabled - Switch 2: Mode of alarm operation o “0” Æ Continuous Alarm (Tag Reader will continue alarming after the Tag has left Signpost field until the alarm is acknowledged by Bypass) o “1” ÆNon-Continuous Alarm (Tag Reader will stop alarming when the tag leaves the Signpost field) - Switch 3: Alarm Buzzer enabled o “0” Æ Alarm Buzzer disabled o “1” Æ Alarm Buzzer enabled

Tag Reader Receiver should always have Switch 3 in position ”0” (Alarm Buzzer disabled). User Guide Functionality The functionality of Tag Reader Receiver is just tom receive messages from Tags and pass them to the Server. The functionality of Tag Reader Door Controller is more complex as it includes interaction between Tag, Signpost and peripheral door controlling hardware. Tag Reader Database The Tag Reader has a local database that enables it to function without any interaction with the Host Server. This database has default set of rules for different Tag types which are used if no rule is stored for a particular Tag. Tag Rules for individual Tags are downloaded from the Host Server whenever the tag is assigned to a person or asset. Tag Rules specify what action should be taken by the Tag Reader upon detection of a particular Tag and in what time period (e.g. activate alarm if the tag is detected between 2:00PM and 2:30PM) Tag Reader database is volatile and it has to be downloaded every time after reset. Alarm and Pre-Alarm When the Tag is detected in a Signpost field and Tag Rules database specifies that it should generate alarm condition, the door state defines is it Alarm or Pre-Alarm condition. If the door is closed, the Tag Reader will lock the door and signal Pre-Alarm (short “chirping”). When the Tag moves out of the Signpost field, Pre-Alarm is stopped and the tag Reader reverts back to Idle mode of operation (note that Switch 2 has no impact on Pre-Alarm). While in Pre-Alarm, the Tag Reader can be bypassed by activating Bypass Input (shorting it) or by sending a command from the Host Server. If the door is open, the Tag Reader will not activate the maglock, but it will signal Alarm condition by beeping long beeps. Switch 2 defines what happens when the tag moves out of the Signpost field; the tag Reader either reverts back to Idle mode (Switch 2 = “1”), or the Tag Reader remains in Alarm Mode until Bypass is started (Switch 2 = “1”). Bypass Bypass can be started by either shorting Bypass Input and Com terminals or by receiving the command from the Host Server. In either case, the Bypass is indicated by 3 short “chirps” every 1 second. While in Bypass, the Tag Reader will not enter Alarm or Pre-Alarm state, but rather it will remain in Bypass state. If the Tag Reader is already in Alarm or Pre-Alarm state, it while exit this states and go into Bypass state. Anti-piggybacking feature: All new Tags entering the field 10 seconds after the Bypass has been started will generate the Alarm or Pre-Alarm.
Signpost – Installation Manual and User Guide Guard RFID Solutions Inc. Page 5 of 7 The Bypass state will last until either all the Tags leave the field or until the door is opened and closed. If the Bypass is terminated by opening and closing the door, the Tag Reader will ignore Tags that were already in the field for 5 seconds (this is Post-Bypass state), after which time it will revert to Idle state and be able to detect all the Tags again. Note that while in Post-Bypass state the Tag Reader will enter Alarm or Pre-Alarm state for all the new Tags entering the field. Audio-Visual Indication There are 4 LEDs and the buzzer which provide information about Tag Reader state: - NET LED is red and is blinking while there is no communication established with the Host Server. The LED goes solid when Tag Reader establishes communication with the Host. - RF LED is red and flashes briefly whenever a massage from a Tag is received. - HCI LED is yellow and flashes briefly whenever a message has been sent to the Host Server. - PMI LED is not used. Tag Reader buzzer is used for indication purposes and annunciation of Alarm, Pre-Alarm and Bypass states. System Verification Guard RFID systems are designed to assist staff in providing a high degree of safety for people and assets and therefore should only be used as a component of a comprehensive security program of policies, procedures, and processes. As with every security system, Guard RFID highly recommends regular system operational checks to verify functional integrity.
