4. Introduction
The STAR-ELT Radio Fire Alarm (KCi Model 99320) is a self-contained Auxiliary Signaling
Device that responds to contact closures from fire panels (FACP), emergency switch devices,
supervisory switch devices and auxiliary switch devices to generate alarm messages in standard
Kingfisher receiver format, and transmits those messages via radio to a compatible Kingfisher
receiver. The STAR-ELT is a microprocessor-based device that utilizes state of the art software
defined radio techniques to generate an appropriate alarm message and transmit the message on a
software-generated VHF frequency.
The STAR-ELT is housed in a NEMA-1 cabinet and derives power from either an FM approved
FACP 24VDC auxiliary power output or from an optional 120-240VAC power supply. When
the optional AC supply is used the STAR-ELT also requires a backup battery. It has the
capability to monitor the status of the optional battery and supply charging voltage to keep the
battery fully charged. Depending on the type of battery installed, the STAR-ELT can operate
from its battery in standby mode for 96 hours following a power failure. The STAR-ELT will
generate a trouble message if it detects loss of AC power, disconnection of the battery, a battery
that does not hold a charge, a charger that cannot properly charge the battery, or a break in any of
the input field wiring connections. To prevent spurious trouble messages, a programmable
confirmation wait time of up to 99 sec can be utilized to prevent 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-ELT panel. The main board can be powered
from a 24VDC FACP aux power output, and regulates this down to its required operating
voltage. When powered from a FACP, a standby battery is not required as the FACP aux power
source is battery backed up. The main board monitors four Class B inputs. It applies debounce
logic to signals on these inputs to prevent responding to external noise. When an alarm
transmission is warranted the radio circuitry builds an alarm message based on the input
activation which is transmitted on a preselected VHF radio frequency channel. Several alarm
message formats that conform to an existing Kingfisher messaging standard can be selected.
Message format specifics are selected by the alarm technician using a laptop computer. An
optional AC power supply provides power and standby battery maintenance when the STAR-
ELT is not powered from a FACP auxiliary 24VDC output or other FM approved 24VDC
source.
The Kingfisher STAR-ELT alarm transmitter is compatible with the following Kingfisher
receiving equipment:
