CR2 Engineering provides low voltage solutions for complex projects throughout the U.S.
A robust and reliable life safety system is essential to healthcare and public safety operations, and CR2 Engineering’s team has the expertise to deliver a system you can rely on. Our hands-on experience ensures successful life safety projects from start to finish.
CR2 Engineering provides fire alarm, nurse call, mass-notification and emergency-call systems design engineering services for the built environment in cooperation with architects, owners and agencies. Our team of life safety systems engineers also provides planning and programming services.
Intelligent Systems Integration
Most of the systems described here send their information over the data network including computers, telephones, intercoms, video cameras, card readers, speakers and audio visual systems. What previously took a bundle of dedicated cables is now a network connection. This integration saves costs and provides operation efficiency. But, it must be designed properly. A network designed to carry computer traffic will not handle video cameras and other devices without a reduction in speed and efficiency. A well thought out building integration plan is critical to today’s facility design.
As devices continue to become IP compatible and evolve, the demand on the network will increase. Many scenarios see the elimination of dated technologies. For example, fiber based Passive Optical Network [PON] see the replacement of copper cabling and mid-tier switches. PON also saves considerable expense with low power consumption and space requirements.
Fire Alarm & Mass Notification Systems
Recent changes to code have expanded the role of fire alarms. With Mass Notification Systems (MNS), fire alarms now provide emergency voice communications for facilities. This integration takes a fire alarm system from rarely used equipment to a key communications platform — the backbone of risk mitigation in any emergency plan. The deployment of MNS starts with a ‘risk analysis’ used to define the features and functions. CR2 has extensive experience in risk analysis and interfacing with authorities, including fire marshals and insurance providers.
Communication systems have evolved from copper cabling to integrated digital devices. Integrated systems are capable of cutting costs such as fire alarm, mass notification, paging and intercom systems. Typical communication systems include:
- Telephone systems
- Voice mail and unified messaging
- Paging systems
- Intercom systems including:
- Area of refuge intercom
- Elevator intercom
- Emergency “blue phone” intercoms
- Television distribution systems
- Digital signage
- Nurse/patient communications systems
- RTLS (Real Time Location Services) for patients, staff and assets
Audio Visual Systems
Audio Visual presentation systems have become a critical component for many facilities. Healthcare, education, corporate, houses of worship and large assembly venues facilities have increasing A/V needs. These range from conference rooms or classrooms, to large divisible training, ballrooms, stadiums and theaters. Facilities need integration with many factors including lighting, HVAC, motorized shades, centralized scheduling, and digital signage. Our acoustical modeling and acoustical engineering abilities design the system to fit your venue. These systems can include:
- Sound reinforcement
- Visual display
- Room control
- Mobile device integration
Security systems are common in almost every building, facility or campus today. They often incorporate an integration of several systems. The research and development spent on security systems technology introduces new innovations daily. Still, we believe that “technology does not mean security.”
Concepts of the Crime Prevention Through Environmental Design, or CPTED, are key to a security plan. They integrate factors such as lighting, landscaping, and architectural design with security technologies.
Preventing crime instead of detecting crime is an increasing focus that can save lives and property.
Key physical security systems include:
- Video surveillance
- Access control
- Intrusion alarm
- Perimeter detection
- Mobile device integration
Physical Security Information Management (PSIM), identification management, and compliance systems integrate security with HR, management, and organization systems.
The network electronics, wireless components and structured cabling system are the backbone to today’s facilities. Networks control and monitor almost every building system including HVAC control, electrical power systems, and all low voltage systems. Effective design integrates the control of these systems to cut redundant costs in installation and service.
Components of the network infrastructure include:
- Copper cabling
- Fiber optic backbone cabling
- Wireless access points
- Distributed antenna systems
- Network electronics including switches, routers and servers
- Control software
- Raceway and grounding systems
For example, fiber based Passive Optical Network [PON] see the replacement of copper cabling and mid-tier switches. PON also saves considerable expense with low power consumption and space requirements.
