Fire Alarm System – Hospital Mercy
Excerpt:
“Design, installation, and NFPA testing of an addressable system with 24/7 monitoring in a high-criticality hospital.”
Overview
We implemented an addressable fire alarm system at Hospital Mercy, meeting NFPA 72 and local regulations. The scope included design, installation, commissioning, training, and a preventive maintenance plan.
Location: Miami, FL
Client: Hospital Mercy
Year: 2025
Sector: Healthcare / Institutional
Objective
Protect patients and staff with early detection, clear signaling, and 24/7 monitoring, while minimizing interruptions to clinical services.
Project Scope
- Engineering and zonal design of the addressable system.
- Installation of central panel, modules, power supplies, and peripherals.
- Integration with manual pull stations and sprinklers (supervision).
- Functional testing by area, documentation, and “as-built” drawings.
- Training for maintenance and safety staff.
Installed Components
- Addressable panel with LCD display and event log.
- Smoke and heat detectors (operating rooms, ICU, critical corridors).
- Manual pull stations for activation.
- Horn/strobes placed at strategic signaling points.
- Input/output modules for integration and zoning.
- 24/7 remote monitoring with alerts and periodic reporting.
Challenges
- Work performed in sensitive areas (ICU and operating rooms).
- Migration from the previous system without stopping operations.
Applied Solution
- Night shifts and coordinated work windows with hospital staff.
- Temporary bypass and segmented testing.
- Double verification and NFPA checklist for each floor.
Results
- NFPA 72 compliance documented and approved.
- Response times < 30 seconds for local activation.
- Delivery of “as-built” drawings, manuals, and preventive maintenance plan.
Preventive Maintenance
- Quarterly inspections of detectors and modules.
- Semiannual testing of horn/strobes and manual pull stations.
- Annual consolidated report with recommendations.
Legnasys Technology Inc. implemented an addressable fire alarm system at Hospital Mercy, in full compliance with NFPA 72 and local regulations. The project included design, installation, commissioning, staff training, and a preventive maintenance plan.
The system incorporated a central addressable panel, smoke and heat detectors in critical areas (ICU, operating rooms, corridors), manual pull stations, horn/strobes, and 24/7 remote monitoring.
Through careful planning — night shifts, phased testing, and strict supervision — the migration was achieved without interrupting hospital operations.
Testimonial
“Legnasys’ coordination was impeccable. They completed the work without affecting critical areas, and the system was 100% validated.”
