Introduction The STAR Radio Fire Alarm (KFCi #99952) is a self-contained Auxiliary Signaling Device that responds to contact closures from standard fire panels, emergency switch devices, supervisory switch devices and auxiliary switch devices to generate an alarm message in a standard King-Fisher KFRA-C receiving processing unit format and transmits that message by radio. The STAR is contained in a NEMA-1 cabinet and derives power from a 120VAC circuit. It maintains a backup battery, periodically checking its status and supplying charging voltage to keep the battery fully charged. The STAR can operate from its battery in standby mode for 96 hours following a power failure. The STAR will generate a trouble message if it detects loss of AC power, disconnection of the battery, a battery that does not hold a charge, or a break in any of the input connections. To prevent spurious trouble messages, a confirmation wait time of 60 sec is applied. If the fault exists for at least 60 sec only then is a trouble message transmitted. This prevents excessive trouble message signals during normal maintenance, such as changing a battery or short duration power failures. There are two basic units that make up the STAR subsystem. An Interface circuit controls the power subsystem and monitors up to six Class B monitored inputs. It applies debounce logic to signals on these inputs to prevent responding to external noise, such as that due to lightning strikes in the area. When an alarm is warranted, the interface triggers the radio transmitter control circuitry to initiate the transmission of the alarm message. The radio circuitry monitors input signals and builds an alarm message that it transmits on a preselected VHF radio frequency channel. Several alarm message formats that conform to an
King-Fisher Company, inc. STAR User Manual Page 3 of 14 KFCi #75952, Revision 3 existing King-Fisher messaging standard can be selected. Message format specifics are selected by the alarm technician using a laptop computer.

It is recommended that conduit not be connected through the top wall of the cabinet. There are several basic connections: AC Power 120V AC power, single phase, with a separate ground wire, is connected to the cabinet at a terminal block in the upper left corner of the subplate. Hot, neutral and ground wires should be inserted to the appropriately marked terminals and screwed down tightly. Wires can be any size up to 10 AWG and can be either solid or stranded copper. Antenna There are two ways to connect an antenna to the STAR. All antennas and feedlines must be 50Ω. The STAR is shipped with a coaxial jumper wire connecting the transmitter output to a BNC connector mounted in the upper right surface of the cabinet. A BNC (or BNX) antenna or feedline can be attached to this connector. Alternately, a 50Ω coax feedline can be brought in through a conduit attached to the sides or bottom of the cabinet and connected directly to the BNC connector in the upper right corner of the STAR Transmitter board.
King-Fisher Company, inc. STAR User Manual Page 5 of 14 KFCi #75952, Revision 3 Alarm Wiring Supervised alarm wiring is connected to a terminal block on the left side of the STAR Interface board. Termination requirements are described below. Battery A backup battery sits in the bottom of the cabinet and connects to the STAR Interface board with a 3-pin Amp connector in the lower right corner. Different backup battery types may be used but the basic requirements are as follows: a sealed lead acid battery must be used with a minimum capacity of 2.5 A-Hr. The battery should be rated for both discharging and charging over the full temperature range that the STAR cabinet will be subjected to. Typically, this is rated from -40°C (-40°F) to +60°C (+140°F). Note that most gel cell sealed lead acid batteries are not capable of operation over this temperature range. STAR Interface Module The STAR Interface Module (KFCi #66951) provides monitored contact closure inputs for up to six connections. Monitoring is based on a 10kΩ EOL resistor, which must be installed across the contacts. If an input is unused, an EOL resistor must be installed across those input terminals. A seventh input can be used to monitor a local energy master box input. This input allows connections to an existing FACP’s L.E. Box trip circuit, if desired. Jumper JP1 on the interface module selects whether or not the local energy input is used. If not, the jumper must be in the Disable position; otherwise it must be in the Enable position. Each input is translated to a function code that is recognized by the King-Fisher KFRA-C console. There are 10 possible function codes and each of the inputs causes one of those function codes to be transmitted. There is no limitation on the translation and it is possible that every input causes the same function code to be transmitted. A programmable debounce time, measured in milliseconds, is also customizable for each input. System Power Supply The Interface module controls the power source for the STAR unit. AC line power is supplied to the Interface after being fused and reduced in voltage by a transformer to 14-35 VAC. The Interface module converts this to regulated DC, whose voltage is adjustable with potentiometer R76. The desired operational voltage of the STAR is based on what is required to properly charge the battery. The Interface module monitors AC voltage and switches the DC power source from the AC-to-DC power supply to the battery when it detects either a brownout condition or total loss of AC voltage. Upon detecting these conditions the yellow Power Fault LED flashes every second. When on battery power, the interface module continues to monitor both the AC voltage, to look for return of AC power, and the DC voltage, to insure that the battery does not become so depleted that it is damaged. There are two operational battery levels that are acted upon by the STAR subsystem. When the battery reaches the Low Battery threshold, all messages sent by the STAR are encoded to also report a Low Battery condition. Later, when the battery is further
King-Fisher Company, inc. STAR User Manual Page 6 of 14 KFCi #75952, Revision 3 depleted and its voltage reaches the Battery Cutoff threshold, the STAR shuts itself down to prevent excessive depletion of the battery (Note that even after the battery is not being drained by the STAR, its internal resistance causes it to continue to lose charge slowly. It is important to recharge the battery soon after shut down to prevent damage to its cells). In this condition the trouble contacts are closed and can be used to indicate to the associated panel that the STAR is no longer operational. When AC is present, every two minutes the STAR removes the battery charging voltage and tests to see if the battery is holding a charge. If not, the implication is either that the battery is faulty and needs to be replaced or that the battery has been removed, one of its wires has broken, or the battery fuse is blown. Any of these conditions requires attention and the STAR indicates power trouble with the flashing Yellow LED and also transmits a trouble message to the KFRA-C after the desired debounce delay has passed. Connecting Alarm Inputs A 12-position pluggable terminal strip connector on the left edge of the Interface module is used to connect to dry contacts from a fire panel. Each pair of contacts should be connected to the two sides of one dry contact. There is no preferred polarity to this connection. There are six such “zones” in the 12 connections. Two indicator lights are located immediately to the left of each pair of contacts on the pluggable terminal strip connector: Red indicates when the input is in an Alarm condition (dry contact closure), Yellow indicates when the input is in a Trouble condition (wire breakage or ground fault). Ground faults are detected individually by each input zone. All input zones must be connected to a 10 kΩ termination resistor. The termination resistor must be placed at the dry contacts. If the input zone is not used the termination resistor leads must be inserted directly into the pluggable terminal strip connector. If no termination resistor is connected to an input that zone will be in trouble. All of the trouble indications are combined to create a single input trouble condition. That can be transmitted as any function in the wireless system with a response delay of up to 65 seconds. Thus, the Interface module can be programmed not to respond to a trouble condition unless it remains in trouble for a period of time. This feature serves to prevent spurious trouble messages when work is being done on the system. A separate two-contact pluggable terminal strip connector adjacent to the input connector gives access to a dry contact trouble relay that can be wired back to an input on the fire panel. This contact closure occurs when the STAR is in power trouble. It is normally-closed so if all power to the STAR is lost, both AC loss and a dead battery, the panel will be able to detect this. Another two contact pluggable terminal strip connector is used to connect to a Local Energy Master Box trip circuit. There is no preferred polarity to this connection. When a Local Energy Master Box connection is used, a jumper must be placed across the center and right hand posts of J9. Alternately, if this connection is not used, the jumper must be moved to the center and left hand posts of J9 to disable it.
King-Fisher Company, inc. STAR User Manual Page 7 of 14 KFCi #75952, Revision 3 Zone Programming The response to a zone alarm can be programmed to elicit many responses on the KFRA-C receiving console. To customize the parameters of the interface board it is first necessary to connect to the programming interface of the card. The computer is connected to the STAR Interface module via an available COM-port, using a King-Fisher programming cable (KFCi #57950). For computers that only have USB ports and no COM ports, a commercial USB-to-COM port converter can be used. Any program that allows users to read and enter characters that pass through a computer’s COM port can be used to perform simple programming functions for the STAR Interface. Once such a program is initiated and connected to the proper COM port press the PROGRAM button on the STAR transmitter board until the green light on the board is illuminated. Once this occurs press the ENTER key on the computer and the terminal emulator window should respond with a log-on message: King-Fisher Company Interface Programmer Enter password to continue: After entering the password followed by the ENTER key, you see the menu: Fware Vers 1.06 Batt Mon 173 (> 87) Zone Tone Debounce(msec) 0 (TRB) 7 20000 1 0 200 2 1 200 3 2 200 4 3 200 5 4 200 6 5 200 7 (LE) 6 200 8 (BAT) 7 30000 9 (PWR) 10 60000 A.

A special tone 10 generates a two-tone sequence that is usually used to indicate power trouble. Any zone can be programmed to send any tone. o Zone 0 is the generic zone for all input troubles. o Zones 1-6 are the input zones on connector J5. o Zone 7 is the local energy input on connector J7. o Zone 8 is activated when there is battery trouble. o Zone 9 is activated when there is AC power trouble. ¾ Store Chnges in Interface – once the changes to the timing and zone definitions are completed, the “S” function must be executed to make them permanent. ¾ Xmit Test Msg – transmits a test message through the transmitter, which send the number of rounds defined for testing. ¾ Quit – when you are done looking at or updating the interface specifications this returns the interface to operational status and the yellow LED goes off. When in the menu if you do not type anything for 60 seconds, the interface times out and you see the message: Inactivity Abort - Returning to Normal Callbox Operation If you want to continue programming interface options you should simply press the ENTER key and log in again if this occurs. STAR Radio Transmitter Module The STAR Radio Transmitter module (KFCi #66950) is a microprocessor-controlled device that responds to contact-closure style inputs, generates an appropriate alarm message and transmits the message in a desired protocol on a software-generated VHF frequency. Programming the Transmitter Most of the specific details of the transmission format are selected from a software screen that is run in a PC-compatible computer running Windows 98 or higher operating system. The computer is connected to the Radio Transmitter module via an available COM-port, using a King-Fisher programming cable (KFCi #57950). For computers that only have USB ports and no COM ports, a commercial USB-to-COM port converter can be used. There are two software interfaces available for both the Interface and the Transmitter boards. The simple interface uses any terminal emulator, such as HyperTerminal, which is included with most Windows®-based computers. Simple Interface Any program that allows users to read and enter characters that pass through a computer’s COM port can be used to perform simple programming functions for the STAR Transmitter. Once such a program is initiated and connected to the proper COM port press the PROGRAM button on the STAR transmitter board until the green light on the board is illuminated. Once this occurs

The Time-of-Day Clock (set with the “C” function) and the Test Time (set with the “T” function) determine when this transmitter will send its periodic test. The unique Box Address (set with the “A” function) should also be set into each transmitter. A Test Message can be sent, using the “X” function to confirm that this transmitter’s signal is seen by the receiving console. If you do not type anything in this menu for 60 seconds, the interface times out and you see the message: Inactivity Abort - Returning to Normal Callbox Operation When this happens, you need to log on again to continue programming the board. The timing information that is programmed into the clock circuit is maintained by a backup capacitor, which will allow the information to be kept for approximately 3 days. Over longer periods of time the time-of-day and test time will have to be re-entered. Hardware Errors Three hardware errors are monitored by the microprocessor and when detected will prevent the transmitter from operating. When any of these hardware errors is detected the transmitter shuts down all circuitry that it can and sends a continuous stream of characters out of its serial port. It
King-Fisher Company, inc. STAR User Manual Page 10 of 14 KFCi #75952, Revision 3 does so infinitely until the problem is corrected by human intervention. Connecting a terminal program to the serial port, as describe above, will show text that indicates the specific problem that was detected. When the transmitter is first started up, or reset, it scans the entire program memory and compares a checksum of the values in it to the checksum that was calculated when the device was originally programmed. If these are different the program memory is assumed to be corrupted and the processor prints the message: “Bad Checksum” repeatedly until the problem is corrected. Every time the transmitter is called upon to transmit an alarm, trouble or test message it sets up the RF circuitry with the proper parameters. It then reads back the RF programming and if there is a discrepancy the processor stops trying to transmit and prints the message: “RF Circuitry Error” repeatedly until the problem is corrected. After the transmitter sets up the RF circuitry but before it transmits anything it checks to see if any RF energy is being sent to the antenna. If so, this indicates a hardware error that would cause the transmitter to tie up the frequency when it is not meant to send a message. In this case, it shuts down power to the RF circuitry and prints the message: “Unintended RF Transmission” repeatedly until the problem is corrected. King-Fisher Transmitter Programmer A higher level software package that is used to program the transmitter is started by double-clicking on the “KF Transmitter Programmer” icon on the desktop or alternately by selecting the same software under Start - All Programs - King-Fisher – Transmitter Programmer. Before the program starts, a small screen that asks for a password appears on the display. The Transmitter Programmer has three functional levels: Factory, Maintenance, and Field. The parameters that can be adjusted are different for each level (see Table 1 and Figures 1, 2 and 3). Prior to using the Transmitter Programmer, it may be necessary to identify which COM port is used to connect to the Transmitter. This is performed by clicking on the Tools menu on the top line of the program screen and then clicking on COM port. A list of COM ports (COM1 through COM8) is displayed. Click on the appropriate COM port number for your hardware. A check mark will appear next to the selected COM port, which will stay set unless it is purposely changed to another port. Once the cable is connected between the PC and the transmitter, the Radio Transmitter module must be put into program mode to affect its programming. This is done by pressing the PROGRAM button located on the Radio Transmitter module and then clicking on the “Connect to Transmitter” button on the PC programmer screen. A successful connection will refresh the Firmware Version number and power supply monitor voltages along the right hand side of the program window with information obtained from the transmitter. When the Radio Transmitter is in Program mode it is not able to function as an alarm transmitter. In case the Program button is pushed accidently or Program mode is not exited, a timer in the
King-Fisher Company, inc. STAR User Manual Page 11 of 14 KFCi #75952, Revision 3 transmitter automatically exits from Program mode and returns the transmitter to normal use if there is no activity over the COM port connection for 1 minute. Be aware that this may also occur before programming is complete and it will be necessary to put the transmitter back into program mode and reconnect the program to the transmitter as described above if this happens. Table 1: STAR Transmitter Parameters Accessibility is from the three different functional levels, each accessible with a different password. “S” means that the parameter can be set from a given level. “V” means that the parameter can be viewed from a given level but not changed. A blank field means that the parameter cannot be changed or viewed at that functional level.
