Flawless ARCS for First Responders from the ERRCS Experts
HiRiseTech provides Developers, Building Owners, GCs, CMs and Low Voltage Contractors with turnkey ERRCS solutions, specifically configured for each structure. We successfully design,install and maintain each system while meeting the most stringent building code requirements in regard to public safety radio communications.
The HiRiseTech solutions for ARCS and ERRCS systems are the product of decades on hands-on experience in dealing with in-building wireless emergency communications.We offer an absolutely reliable product developed for First Responders working in the most harsh and difficult environments.
HiRiseTech has designed a reliable, fully compliant, easy-to-install,easy-to-use very cost-effective system.
Before considering installation of an ERRCS in an existing building or a building under construction, a comprehensive site survey is conducted in order to assemble all the information needed to ensure successful system customization and deployment.
HiRiseTech has substantial experience in the installation of ERSS systems in New York City including the World Trade Center.
Since the HiRiseTech solution basically involves wireless Installation it can be integrated into both existing structures and buildings under construction in a very short time with minimal aggravation.
As part of the turnkey project and during deployment, HiRiseTech takes full responsibility for control, and closure of all facets of the work involved and ensures that the system fully meets all contractual requirements.
HiRiseTech offers customers a comprehensive maintenance program which includes preventative maintenance, on-going monitoring and rapid repair carried out from a local maintenance center. On-going system support service packages can be customized to meet individual customer needs.
HiRiseTech’s innovative patented technology was developed by a team of competent developers and entrepreneurs with dozens of years of experience in the realm of wireless communications and business development. HiRiseTech employs the team’s accumulated experience in the fields of consulting, development, project management, installation and maintenance to successfully deliver turnkey design built projects.
HiRiseTech’s works hand-in-hand with the construction industry to ensure that new and existing high-rise construction projects fully comply with NFPA 1221 and other standards for First Responders Radio communications.
The HiRiseTech patented invention for an ERRCS fully complies with and covers all the New York City Buildings Department and NFPA Fire Code requirements while being a cost-effective and simply-deployed solution.
Present technologies offer expensive, time-consuming and tedious solutions.
In buildings in which the HiRiseTech ERRCS is deployed, firefighters continue to use their Standard Portable Radios to maintain effective communications from any point on any floor in any building – no matter how high or how complex it is.
The system is composed to two standard ground-floor Consoles for full Channel 11 and Channel 12 activation. A cable connects each Console to the Central Control Unit (CCU) in the Fire Control Center (FCC) of the Building. The CCU is, in turn, connected to a single RF Riser which distributes signals to an array of Smart Splitters – one on each floor – each connected to at least two antennas.
A voice signal from a Firefighter, as received by multiple antennas, is processed by the CCU in real time and returned to the whole building via the Smart Splitters and RF Riser, thus achieving full building coverage.
Automated control of strength of output power per antenna depends on the structure of the building.
The system includes a built in Cyclic Health mechanism that continuously monitors the system health up till the level of each antenna. In the event of a malfunction of a system element, the system raises an alarm on the Console display.
The system is completely passive with power required only by the CCU in the FCC.
The HiRiseTech solution has been deployed in several building in New York City including the World Trade Center.

Schematic Drawing of System
The following drawing provides an overview of the system.
Regulatory requirements for two-way Emergency Communication Systems (ECS) are specified in National Fire Protection Association NFPA 1221®: Standard for the Installation, Maintenance, and Use of Emergency Services Communications Systems. NFPA dictates the deployment of Auxiliary Radio Communication Systems (ARCS) or Emergency Responders Radio Coverage Systems (ERRCS) in thousands of high-rise buildings in order to provide radio coverage for First Responders.
Reliable emergency communications are critical to effective emergency response by First Responders – fire services, law enforcement, emergency medical services, and others. NFPA 1221® addresses service delivery – from receiving calls to dispatching emergency units to the correct location in the defined period of time.
Such a system must integrate with existing portable radios used by First Responders to ensure total and seamless communications during an emergency.
Many public-safety and building-code officials realized that an effective national standard for ARCS was needed to ensure uniformity, guarantee effectiveness and encourage widespread adoption. Toward that end, the NFPA 1221® was developed. It provides safety provisions to meet fire detection, signaling, and emergency communications demands. One of the goals is to make available a structured approach for the development and implementation of emergency communication strategies.
Section 9.6 (Two-Way Radio Communications Enhancement Systems) provides a comprehensive, integrated approach to fire code regulation and hazard management and offers specific recommendations for performance, testing and monitoring of the radio enhancement system.
The following elements are required:
The system must operate without causing interference to other parts of the public-safety radio system (section 18.104.22.168)
Critical areas of buildings must have 99% coverage and general areas must have 90% coverage (sections 22.214.171.124 and 126.96.36.199).
Minimum inbound and outbound signal strengths of DAQ 3.0 for either analog or digital signals (section 188.8.131.52)
The system must be capable of retransmitting all relevant public-safety frequencies (section 9.6.10).
At least two independent and reliable power supplies must be included (section 9.6.12).
A 12-hour battery backup ensuring 100% system operation is necessary (section 184.108.40.206).
An automatic-monitoring system with a dedicated panel in the fire command center of the building is mandatory (sections 220.127.116.11 and 18.104.22.168).
Ability to add system frequencies (section 22.214.171.124).
Fire Department of New York Standards
On December 31, 2014 the Fire Department of New York adopted the provisions of NFPA 1221® under Promulgation Details for 1RCNY 3616-04).
The FDNY has adapted NFPA 1221® with the following very strict and complex requirements:
Dedicated Radio Console fire command center with handset or headset , visual display, fire department standard key (#2642)
In-Building Auxiliary Radio Communications System (ARCS)
Must cover 100% of building critical areas
Must cover 95% of total floor space
Minimum inbound signal strength of -95 dBm.
Minimum outbound signal strength of -95 dBm.
Perimeter: building’s limits
Frequencies: all public safety frequencies (UHF)
Signaling: rebroadcasting to all receiving radios
Power Supply: in accordance with section 760.41 of the NYC Electrical code.
Emergency transmission interrupt
Retransmit or display firefighter’s IDs
Ability to withstand 90o C heat
Should a building fail to meet the necessary coverage requirements, NYC building code requires either a repeater channel system or a simplex channel system.
The HiRiseTech First-Responder Radio System (FRRS) solution fully meets the requirements of NFPA 1221® and the FDNY.
