ERCES Installation: Bringing the Design to Life

ERCES installation transforms your approved design into a working system. Professional installation is critical—improper installation can result in failed inspections, inadequate coverage, and costly rework.

Installation Overview

A typical ERCES installation includes:

1. Donor antenna installation on the roof
2. BDA (Bi-Directional Amplifier) installation in equipment room
3. Cable routing throughout the building
4. Distribution antenna installation on each floor
5. Power and monitoring connections
6. System optimization and testing

Pre-Installation Requirements

Before Installation Begins

Ensure the following are complete:

• AHJ design approval received
• Building permits obtained
• Frequency coordination documented
• Equipment ordered and received
• Installation contractor selected
• Building access coordinated
• Other trades coordinated (electrical, fire alarm)

Site Readiness

The building should have:

• Dedicated electrical circuit for BDA equipment
• Equipment room space with proper ventilation
• Roof access for donor antenna installation
• Cable pathway access (risers, conduits, ceiling space)
• Fire alarm interface ready (if required)

Donor Antenna Installation

Location Selection

The donor antenna should be positioned to:

• Have clear line-of-sight to public safety towers
• Minimize cable run to BDA
• Be accessible for maintenance
• Be protected from physical damage

Installation Requirements

Requirement	Specification
Mounting	Rated for wind/ice loads
Grounding	Per NEC and manufacturer
Weatherproofing	All connections sealed
Lightning protection	Appropriate arrestors
Cable routing	Protected from damage

Common Donor Antenna Types

• Yagi antennas for directional coverage
• Omnidirectional antennas for multiple tower directions
• Panel antennas for specific directional needs

BDA Installation

Location Requirements

BDAs should be installed in:

• Climate-controlled spaces (0-50°C operating range)
• Areas with adequate ventilation
• Accessible locations for maintenance
• Protected from physical damage
• Near electrical service

Installation Best Practices

Mounting:

• Secure wall or rack mounting
• Adequate clearance for airflow
• Accessible for service

Electrical:

• Dedicated circuit as specified
• Proper grounding and bonding
• Surge protection

Connections:

• Proper connector installation
• Cable strain relief
• Labeled connections

Cable Installation

Cable Types

Cable Type	Application	Fire Rating
Coaxial (plenum)	Distribution runs	CMP rated
Coaxial (riser)	Vertical runs	CMR rated
Fire-rated	Survivability areas	2-hour rated
Hybrid fiber	Long runs	Per application

Routing Considerations

Pathway Survivability:

• Follow NFPA 1221 requirements
• Use fire-rated pathways where required
• Maintain proper firestopping

Signal Quality:

• Minimize cable lengths
• Avoid sharp bends
• Maintain separation from interference sources
• Use appropriate connectors

Installation Standards

• Maximum bend radius per manufacturer
• Proper support intervals
• Labeled at both ends
• Tested after installation

Distribution Antenna Installation

Antenna Placement

Distribution antennas are placed based on:

• Design coverage calculations
• Building construction materials
• Ceiling height and type
• Aesthetic requirements

Common Antenna Types

Ceiling-mount omnidirectional:

• Most common for office areas
• 360-degree coverage pattern
• Typically mounted above ceiling tiles

Wall-mount directional:

• For corridors and specific areas
• Focused coverage pattern
• Visible mounting

Public safety DAS antennas:

• Purpose-built for ERCES
• Appropriate frequency coverage
• UL listed components

Installation Requirements

• Secure mounting per manufacturer
• Proper connector installation
• Antenna orientation per design
• Accessible for testing and maintenance

Power and Monitoring

Power Requirements

ERCES systems require:

Primary Power:

• Dedicated circuit(s)
• Appropriate amperage
• Surge protection

Backup Power:

• Battery backup (typically 12-24 hours)
• Proper battery installation
• Charging system

Monitoring Connections

Connect to building systems:

• Fire alarm panel (supervisory)
• Building management system (optional)
• Remote monitoring (if required)

Quality Control During Installation

Inspection Points

Phase	Inspection Items
Rough-in	Cable routing, pathway protection
Equipment	BDA mounting, connections
Antennas	Placement, mounting, connections
Final	Complete system, labeling

Documentation During Installation

Maintain records of:

• Equipment serial numbers and locations
• Cable routing and lengths
• Test results at each phase
• Any deviations from design
• Photos of concealed work

Common Installation Challenges

Challenge: Existing building infrastructure limitations Solution: Coordinate with building management, plan alternative routes

Challenge: Construction schedule conflicts Solution: Early coordination with general contractor

Challenge: Signal interference from other systems Solution: Identify sources, adjust antenna placement or add filtering

Challenge: Aesthetics concerns in finished spaces Solution: Use appropriate antenna types, coordinate placement

Working with Installers

Contractor Qualifications

Look for installers with:

• ERCES-specific experience
• Knowledge of local AHJ requirements
• Proper licensing and insurance
• Manufacturer certifications
• References from similar projects

Installation Timeline

Typical installation duration:

Building Size	Duration
Small (under 50,000 sf)	1-2 weeks
Medium (50,000-200,000 sf)	2-4 weeks
Large (over 200,000 sf)	4-8+ weeks

Factors affecting timeline: building complexity, access restrictions, coordination requirements.

Next Steps

After installation is complete:

1. Contractor performs initial system testing
2. Address any coverage issues
3. Prepare for commissioning
4. Schedule AHJ inspection
