WARNING:
 Changes or modifications not expressly approved by King-Fisher Company, inc 
could void the user's authority to operate this equipment. 
 
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital 
device, pursuant to Part 15 of the FCC Rules.  These limits are designed to provide reasonable 
protection against harmful interference in a residential installation.  This equipment generates, 
uses and can radiate radio frequency energy and, if not installed and used in accordance with the 
instructions, may cause harmful interference to radio communications.  However, there is no 
guarantee that interference will not occur in a particular installation.  If this equipment does 
cause harmful interference to radio or television reception, which can be determined by turning 
the equipment off and on, the user is encouraged to try to correct the interference by one or more 
of the following measures: 
¾  Reorient or relocate the receiving antenna. 
¾  Increase the separation between the equipment and receiver. 
¾  Connect the equipment into an outlet on a circuit different from that to which the receiver 
is connected. 
¾  Consult the dealer or an experienced radio/TV technician for help. 
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
