FIRE - BK - Catalyst Communication Technologies


Field Incident / Repeater Element – BK Technologies (FIRE™ – BK) provides transportable radio communications, command, and control where radio communications is spotty or does not exist. Typically, these applications include incident command in geographies with poor radio communications, or in-building incidents – especially fire – where radio communications may be compromised. FIRE™ – BK is specifically designed to work with BK Technologies KNG Series Mobile, offered in four frequency bands and two power options, 50 or 100 watt.
FIRE™ – BK provides enhanced graphics and control for radio voice communications across multiple frequency bands and multiple types of radio systems including Project 25, MDC 1200 and conventional. FIRE™ – BK provides essential information for fireground, emergency medical, special rescue, utility restoration and other public safety and critical infrastructure incidents. A single computer, including a laptop, is all that is needed to control up to two mobile radios and provide the control and user interface that can be operated in stand-alone mode or linked back to the agency’s primary radio system and to other radio channels as needed.
This rugged, compact, and efficient solution can be purchased in a robust travel case or installed in a vehicle.

FIRE Front 2 Radios (2)

FIRE™ – BK in a Simplex Fire Ground Application

These units may be configured with two mobile radios. With two radios operational, one radio can be operating in full P25 trunked mobile radio mode. The second radio is operating in simplex mode (single frequency used for TX and RX). In this mode, FIRE™ – BK can allow full featured trunking and simplex operation and can link the two to allow fire ground communications to be linked to the trunked LMR radio system for access by dispatch consoles and other trunked radio talk groups. These units can record all Fire Ground communications locally as well as transfer all communications to the trunked system for capture by the trunked Voice Logging Recorder – essential for subsequent incident review or training.

FIRE™ – BK in a Repeater Fire Ground Application – Enhanced Digital Vehicular Repeater Application

In this application, FIRE™ – BK is configured with two mobile radios. In this operational mode, both of the radios are operational in a “repeater” mode. One radio is operating in transmit only mode (single frequency used for TX) and one radio is operating in receive only mode (single frequency is used for RX). These units use software to route the audio as needed to replicate “repeater” mode for the Fire Talk Group. These units can record all Fire Ground communications locally– essential for subsequent incident review or training.
Especially useful for fire incidents, these units, as a combined digital repeater and incident command, provide for the ability of First Responders to better communicate in a number of important ways:
• Incident Commander outside the building to First Responders in the building.
• First Responders to First Responders within the building.
• First Responders emergency call (via emergency button) both inside and outside of the building to the Incident Commander.
• Support for communications between all Portable and Mobile Subscriber Units on the Fire Ground.
• All communications is recorded, stored, and accessible.

FIRE™ – BK Interface: Manage Local Communications

When fire fighters or other public safety or critical infrastructure officials choose to operate their two-way radios in talk-around or local repeat mode, it can be difficult to coordinate in the absence of communication with the main dispatch center. FIRE™ – BK allows the Incident Commander to monitor voice communications from these radios across the primary frequency bands using one integrated tool. Commanders see a running list of which radio placed each call with a time stamp. Emergency messages are highlighted and saved on the device and can be managed from it. The audio can be recorded, saved locally, and replayed on-scene or later. Pre-programmed alert voice messages or tones can be broadcast with a single press.

Key Features

Key features include powerful local patching to create a Digital Vehicular Repeater or connect multiple agencies, recording of audio and the associated Meta data (Unit ID, Emergency, etc.) with Instant Playback, rapid access to hundreds of channels across multiple frequency bands, and a simple set of graphical controls designed for fire fighters, policemen, and other first responders.

Patch Talk Around to the Trunked Radio System

FIRE™ – BK can link two mobile radios together to patch Talk Around traffic to the local trunked radio system. Catalyst technology dynamically manages the audio flow so that syllables are not lost. Trunked radio systems vary in the amount of time it takes to gain access to a channel. These units can store the audio until the trunked system is ready to receive it and then transmit the audio to the trunked system, the dispatch center, and your primary logging recorder.

Interoperability with Control

Many interoperability solutions in the marketplace provide the ability to patch together one or more radios and link talk groups within those radios. By adding a Dispatch capability to an interoperability solution, an Incident Commander has greater control over radio communications and can modify interoperability patches as needed.

Record & Play Back Local Audio

When public safety officials are operating in talk-around or local repeater mode, their conversations can go unrecorded. FIRE™ – BK provides the option to record the currently monitored channels on each local device. Typically, as much as one week of actual talk time through a mobile radio can be stored on these units, allowing for simple review and sharing during the incident or afterwards.

Additional Features


Two BK Technologies radios can be used to provide interoperability between UHF, VHF, 700 MHz, and 800 MHz as well as Project 25, MDC 1200 and conventional.

Compact and Efficient

A single laptop computer running Catalyst software can control mobile radios, record radio traffic and metadata, and provide a user friendly graphical interface.

Local Repeater

FIRE™ – BK allows the Incident Commander to rebroadcast transmissions from local units at a higher power or on a different frequency so on-scene responders can communicate with one another. BK Technologies radios are available with 50 watt and 100 watt power configurations.

Quickly Respond

Tune FIRE™ – BK to the desired channel of a recent call with one click.

Simple and Intuitive Functionality

Catalyst can configure these units with a custom layout and stage it with your radios so that when you need communications, it will be ready. Just turn it on and immediately enhance your communications and record keeping.
