(describe the base station radio board). 5 Personnel Alert: Base Station User Manual The Personnel Alert Base Station The Personnel Alert Base Station (base station) is a wireless alarm notification system that is designed to operate in conjunction with fixed gas detection equipment and/or plant alarm systems. The base station continuously broadcasts to portable alarm receivers (badges). If an alarm condition is received from a fixed gas detection unit or from a plant alarm system, the base station immediately broadcasts the alarm to all badges within the coverage area. For more information about the badges, refer to Badges. Each base station maintains an individual number and alarm acknowledgement information for each badge. This information is used to account for personnel during an alarm response situation, such as an evacuation. Table 2. Personnel Alert Base Station Item 1 2 3 Function 2 dBi dipole antenna Explosion-proof enclosure Cable conduit access 1-256 badges can be monitored on a single base station simultaneously. Up to 999 badge IDs can be recognized by 6 each base station, depending upon the database and configuration of the overall system. Figure 1. Personnel Alert Base Station Control Bay Each base station maintains a control bay that consists of an LCD screen and a low light sensor to provide information to monitoring personnel. Table 3. Control Bay Function Liquid crystal display (LCD) Low-light sensor Faceplate security screw Item 1 2 3 The control bay does not have any manual functions and is used to provide information only. To set parameters and configurations for badges and monitoring coverage areas, refer to Area System Planning and Setting the Badge IDs.

Base Display Elements Item 1 2 3 4 5 Function Transmission signal icon Numeric value of badges being monitored in the coverage area Alarm icon Numeric value of how many badges have acknowledged the alarm Alarm severity level: HIGH, LOW, and SYTEM. Liquid Crystal Display (LCD) The LCD displays information automatically and continuously. It displays the transmission signal icon to indicate that it is broadcasting, how many badges are currently in the coverage area, if there is an alarm, the severity of the alarm, and how many badges have acknowledged the alarm. 8 Figure 3. Base Display Elements The base station continually broadcasts to the badges within the designated coverage area. If a badge is no longer detected after 10 seconds, the base station determines that the worker is no longer in the coverage area. The base station then decreases the numeric value by one and displays the new value on the LCD. When a new badge is detected, the value automatically increases. Badges The alarm receivers are referred to as badges that are carried by personnel to provide immediate notification in the event of an alarm condition. The badges continuously monitor broadcast messages from the base station(s). If an alarm condition occurs, the badges emit audible and visual alarms, and vibrate. The badge LCD also displays the severity of an alarm: HIGH, LOW, and SYSTEM. If alarm notification is received, personnel then use the badge to acknowledge the alarm. A message is immediately sent back to the base station while personnel are evacuating the area. Table 5.

Radio Board The radio board is used to 11 Personnel Alert: Base Station User Manual Mounting Guidelines When mounting the base station, adhere to the following guidelines:
To optimize the radio performance and acquire maximum coverage, install the base station at or near the centre of the selected coverage area. Install the base 4-5 meters (8-10 ft.) above ground level. Ensure that the base station is not obstructed by surrounding objects. Do not install the base station below 6 ft. of the above ground level as the range of the transmitter will be reduced. Do not install the base station directly against a wall, especially a metal wall. To prevent impaired radio performance, ensure the base station is installed with a minimum of 18 inches clearance from the wall. If possible, install the base station in a location where the antenna will have a clear line-of-sight with the badges. Install the base station as far away as possible from other antenna systems to avoid possible radio frequency interference (RFI). Do not locate the base where it can be exposed to electrical shock and/or severe mechanical shock. Note Atmospheric conditions may cause signal loss. aWarning The Personnel Alert Base Station is only certified with the supplied 2 dBi dipole antenna. Do not substitute this antenna with another. 12 Preparation for Mounting the Base From the front view, the base station is equipped with pre-
drilled mounting flanges and a threaded inch National Pipe Thread (NPT) conduit fitting outlet on the left side. Attach the base station to a bracket and mount on a pole using bolts through the two mounting holes. Table 8.

The base station has inputs for high, low, and system alarms. The wetting voltage for these circuits are included with the base. Depending upon the normally open (NO) normally closed (NC) operation of the alarm contacts, each alarm circuit can be configured to be NO or NC by setting dip switch S1 on the radio board. aWarning If the area is classified, the base station must be de-energized before testing alarm contacts. NO alarm contacts 22 NC alarm contacts Alarm conditions that are broadcasted by the base station to the badges can be sent through relay contact circuits. The circuits are connected to the base station and they transfer data using MODBUS. If this option is used, each circuit must be set for either NO or NC. If no alarm contacts are installed, the S1 dip switch can be used to trigger alarms to test the system setup. Open or close a single switch to test.If no alarm contacts are installed, the S1 dip switch can be used to trigger alarms to test the system setup. Note For more information regarding alarm testing and dip switch settings, refer to Manual Alarm Test Settings. Table 13.

Testing Manual Alarms aWarning If the area is classified, the base station must be de-energized before testing alarm contacts. Radio Frequency (RF) Optimization The radio configuration requires that the base station channel hopping pattern be set, and the transmit/receive attenuation levels be adjusted. Channel Hopping Pattern The base station hops randomly to fifty frequencies, continually repeating the transmit-listen-hop pattern. Figure 15. Alarm Relay Contact on Radio Board 24 The hopping pattern for each base station is selected from one of seven channel-hopping algorithms. On the radio board, the hopping pattern can be selected from S2, by configuring the binary representation of channels 0 through 7. Set the binary representation as follows:
bit 0
= switch is closed bit 1
= switch is open Personnel Alert: Base Station Radio Frequency (RF) Optimization Single Base Station System: For systems that require only one base station, any dip switch setting can be used on S2. Multi Base Station Systems: For systems consisting of more than seven base stations, the risk of interference is minimal when using the recommended Honeycomb pattern setup mode. The optimum layout for multi base station systems is the Honeycomb pattern. Refer to Area System Planning and Figure 5.Honeycomb Pattern. The numbers in each hexagon represent the decimal equivalent for the dip switch setting that should be used for switch S2. Maintain a record of the pattern that is selected for each base station to ensure that settings are not duplicated for adjacent base stations. Refer to Table 6 for an example. Table 14. Base Station S2 Dip Switch Setting Example Base Station #

Zoltan 25 Personnel Alert: Base Station User Manual a Caution For multi-base station installations, ensure that adjacent base stations do not have the same hopping pattern, as interference will result. The following Table 7. Frequency Hopping Pattern represents the decimal to binary conversion for the dip switch S2 settings. 0-6 and 7=1 (Zoltan) Table 15. Frequency Hopping Pattern Decimal 1 2 3 4 5 6 7 111 100 101 011 110 010 001 Binary Adjusting the Transmit/Receive Attenuation Levels Area coverage of the base station can be controlled by adjusting the transmit/receive attenuation levels in the base station to match the actual radio coverage area that was determined during the area system planning. The attenuation adjustments are also used to tune the amount of coverage overlap between base stations. Proper operation of the Personnel Alert system requires that robust data transfer in both directions: from the base station to the badges, and from the badges to the base station. 26 The 1 Watt maximum transmit power of the base station can never be exceeded. However, by using the attenuation adjustments, it can be reduced by up to 40dB. Attenuation can also be used to adjust the receive path in the base station to maintain a similar loss in both the receive and transmit links. The transmit power levels and the receive sensitivity are fixed for the badges and cannot be adjusted. To adjust the base station attenuation levels, it is necessary to physically walk with a badge within the coverage area(s) to determine the range of each base station. After establishing the boundaries between the coverage areas, review the site plans to determine if base station power levels need to be reduced. If a coverage hole is revealed, verify if an additional base station is required, attenuation reduction of the neighbouring base stations is required, the mounting height of the base station needs to be increased, or the location of the base station needs to be changed. Note Adjusting attenuation levels requires trial and error to test various settings for optimum transmission. For the base station, initially set both the transmit and receive paths to minimum attenuation levels for maximum power. If overlapping results between base stations, then adjust the attenuation to reduce the span of the coverage area. c) Transmit Rotary Switch: The transmitter rotary switch is used to increase/decrease the base station output power. Figure 16. Transmit Rotary Switch Maximum Power Setting Set the switch to F for maximum output power. Set the switch to E to decrease the output power by 2dB and 0 decreases by 30db.

Receiver Sensitivity Switch. The switch setting for the receiver sensitivity (Rx Gain) should be set the same as the transmit switch (Tx Gain) to balance the transmit/receive path losses. Note If the RR jumper is shorted, it further reduces the receiver sensitivity by 11-12 dB. 28 Table 17. Receiver Sensitivity Switch Rx Chain Attenuation Rx Gain Rotary Switch Setting F

For normal operation (high Tx power/high Rx sensitivity), open the reduced radio range jumper. Note This jumper should only be used when the transmit/receive rotary switches are incapable of providing sufficient signal attenuation for defined small coverage areas. open = only one pin is covered graphic When the reduced range jumper is closed, an additional 10 dB is acquired for the transmit attenuation. The receive sensitivity for the base station is reduced by 11-12 dB. Personnel Alert: Base Station Setting the Badge ID Setting the Badge ID The base station maintains the ID number and alarm acknowledgement information for each badge while in the coverage area. This information is used to account for personnel during an alarm response situation, such as an evacuation. 1-256 badges can be monitored on a single base station simultaneously. Up to 999 badge IDs can be recognized by each base station, depending upon the database and configuration of the overall system. Setting-up Badge ID Numbers The badge ID number is used to identify the employee who is carrying the corresponding badge during an alarm condition. When setting up ID numbers, maintain a log to verify employees and badge ID numbers. Refer to the following table. Table 18. Active Badge Table Employee Name Badge ID#
John Smith Jane Doe 001 002 29 Personnel Alert: Base Station User Manual Setting-up the Badge IDs Read the following procedures prior to accessing the badge ID set-up screen. To set-up the badge ID numbers, complete the following:
Note The badge IDs should be set-up prior to the employee entering the coverage area to ensure proper safety. The NO SIGNAL icon displays during the setup. Receiving broadcasts are not required during the set-up process. The base station will automatically identify any badge that has been set-up. 1. The badge set-up can only be accessed during the start-up process. If required, deactivate the badge. 2. Press C and continue to hold until the badge ID setup screen displays and the side LED flashes once (approximately 10 seconds). 30 The badge emits the audible alarm, flashes, and vibrates the same as during normal start-up. The audible alarm, flashes, and vibrating will stop for 3 seconds. Continue to hold the C button. When the side LED lights, release and immediately press C again. Area System Planning Base stations can be configured to operate as single or multiple notification systems, depending upon the area of the zones, complexity of the area (buildings / obstructions), indoor and/or outdoor installations, alarm/emergency response procedures, number of badges, and the functional requirements of the badges. The base station system can be configured for individual and unique requirements. Note Area system planning and configurations must be performed by qualified personnel only. Personnel Alert: Base Station Area System Planning Note Radio link and capacity can be affected and reduced by radio interference from other wireless sources outside of the Personnel Alert system, as well as other base stations. The base station transmitter default setting is set just below the 1 Watt maximum limit. The badges transmit at a fixed RF power level of approximately 50 mW (17 dBm). Systems without a sufficient number of base stations can experience coverage holes where communication between the base station and the badges is not reliable, therefore placing personnel at possible risk. To resolve the challenge of adequate coverage, use a honeycomb pattern system. Refer to Figure 19. Prior to configuring the base station, an area system plan must be developed. To determine the particular requirements of your system, complete the following sections:
Single or Multiple Stations To determine if single or multiple base stations are required, the overall area must be known. Each base station is designed to accurately broadcast to a radius of 45 metres
(150 ft.). The base station can broadcast to a radius of 150 metres (500 ft.) across open terrain and flat areas. Each base station can accurately broadcast to and track up to 256 badges. Use the following guidelines to determine the system requirements. Area and Radio Frequency (RF) Coverage It is necessary to initially determine how large of an area each base station will be broadcasting to. The base station operates on the 902-928 MHz unlicensed radio band, and is subject to federal regulations that restrict RF to transmit power to a maximum of 1 Watt (30dBm) or less. 31 Personnel Alert: Base Station User Manual Figure 18. Honeycomb Pattern Each number represents the recommended frequency hopping pattern for the dip switch settings. For information refer to Channel Hopping Patterns and Setting the Dip Switch Addresses. 32 To develop a system plan, complete the following:
1. Using a site plan (scale drawing) or an AutoCAD model, design a repeating pattern of seven hexagonal cells in a honeycomb to determine the number and approximate locations of the base stations. The seven cell honeycomb pattern is optimum because it allows for the re-use of frequency hopping pattern algorithms within the same system. 2. To determine the location of a base station, consider where it will obtain optimum transmission with surrounding badges. The final layout will not result in a perfect honeycomb pattern. However, if the base stations are installed within ten meters of the layout location, required coverage will be achieved. 3. When more than one base station is required to adequately cover an area, use the hexagon cell with a distance of 90 m (300 ft.) between opposite corners. Each hexagon equals a radius of 45 m
(150 ft.). Refer to Figure 6. Base Station Broadcast Coverage. Figure 19. Base Station Broadcast Coverage Note Determine system planning by using a 45 m (150 ft.) coverage radius around each base station. Do not exceed the radius as radio transmissions can be compromised. 4. When a honeycomb pattern system has been defined on paper, ensure that the selected physical locations are feasible for installation of the base stations. Personnel Alert: Base Station Area System Planning Identify System Obstruction RF Challenges Radio signals transmit well over flat terrain and open water. However, buildings, metal tanks, and other obstructions can interrupt radio transmissions and will therefore require additional base stations to be strategically placed. Placement of base stations within buildings and structures is a factor as walls, pipes, and plant equipment are obstructions. Additional factors that can reduce area coverage are high levels of electrical noise, large metal structures, and inadequate number of base stations on a system. RF interference, As continuous radio transmissions are essential to ensure effective and constant communication between the base station and the badges, line-of-site placement can effectively resolve obstruction challenges. System Capacity / Badge Requirements Next determine how many badges will be receiving broadcasts from each base station (1-256 per base station). The badges can be used to only notify personnel of alarms, or they can also be used for alarm acknowledgement with ID tracking. 33 Personnel Alert: Base Station User Manual Alarms (TBD) The following table describes the system alarms and shows how the display looks for each alarm.
