Bhuj Multi-Specialty Hospital — Addressable Alarm Upgrade
A multi-specialty hospital in Bhuj with 120 beds across four floors faced Fire NOC renewal rejection due to an obsolete conventional fire alarm system installed 14 years earlier. The existing system could not identify fault or alarm locations beyond a floor-level zone — when a detector faulted, maintenance staff searched entire floors to find the defective unit. Horn-only notification on patient floors lacked voice evacuation capability required by Gujarat fire authorities for healthcare occupancies. Emergency lighting on the third and fourth floors had multiple failed battery units discovered only during the fire officer's renewal inspection. The hospital needed a complete alarm upgrade without evacuating patients or closing clinical services — a requirement that ruled out single-phase demolition and replacement.
Systems Installed
- •Addressable fire alarm panel
- •Smoke detectors and MCPs
- •PA/VA voice evacuation
- •Emergency lighting coordination
Challenge
The upgrade had to proceed floor-by-floor while maintaining partial fire protection coverage on all occupied floors at all times. Patient floors with bedridden and post-surgical occupants could not tolerate full-building alarm testing during daytime hours. Night work was required on clinical floors to install devices and run cables without disrupting outpatient services and diagnostic procedures on ground and first floors.
Voice evacuation messaging needed Gujarati and English announcements per fire authority guidance for healthcare facilities — pre-recorded messages directing staff to evacuate patients by zone rather than triggering building-wide panic. Integration with the hospital's existing PA system was evaluated but rejected due to reliability concerns; a dedicated PA/VA fire voice system was specified instead.
The conventional system's existing wiring infrastructure — over 3 km of cable routed through ceiling voids shared with medical gas piping and HVAC ducting — required careful survey before reuse versus replacement decisions. Reusing viable cable routes reduced installation time and ceiling void disruption in occupied clinical areas.
Solution
Rachna Fire & Safety installed a new addressable fire alarm panel with four-loop architecture in the ground floor security room, allowing phased cutover one floor at a time. Each floor received addressable smoke detectors in corridors and rooms, manual call points at nurse stations and stairwell landings, and voice evacuation speakers replacing horn-only sounders on patient floors.
Phase 1 (ground floor and basement diagnostics) was completed and tested during a weekend closure of outpatient services. Phase 2 (first floor — ICU and OT) required night installation over two weeks with daily testing before morning clinical sessions. Phases 3 and 4 (second and third floor patient wards) followed the same night-work pattern. Each phase was signed off with functional testing before proceeding — maintaining at minimum conventional system coverage on non-upgraded floors throughout.
Emergency lighting remediation ran parallel — replacing 38 failed battery units on upper floors and adding photoluminescent exit signage at corridor intersections identified as deficient during our initial gap audit. Voice evacuation was configured with zone-specific Gujarati and English messages: general alarm on ground floor, patient evacuation guidance on upper floors, and staff-only alert in ICU during initial alarm verification phase.
Outcome
Fire NOC renewed successfully with full addressable coverage, functional voice evacuation demonstrated to the Bhuj fire authority inspector, and emergency lighting passing power-failure simulation on all floors. The entire upgrade completed in nine weeks without a single day of clinical service interruption or patient transfer.
Hospital enrolled in Rachna Fire & Safety AMC with quarterly detector testing, annual panel battery certification, and voice evacuation message verification. Maintenance staff now receive exact device location on the addressable panel display — reducing fault investigation time from hours to minutes.
The hospital administrator reported improved staff confidence during the first post-upgrade fire drill, where voice evacuation messages in Gujarati enabled orderly patient movement to safe zones within four minutes — compared to 12 minutes with the previous horn-only system during the prior year's drill.
Technical Details
Building: 4-storey multi-specialty hospital, 120 beds, 8,500 sq.m total floor area. New panel: addressable 4-loop fire alarm control panel with 600-point capacity, battery backup 48 hours standby / 30 minutes alarm. Devices installed: 186 addressable smoke detectors, 32 manual call points, 64 voice evacuation speakers, 12 interface modules for fire door release and lift homing.
Voice evacuation: dedicated PA/VA amplifier system with pre-recorded Gujarati and English messages, zone-selective broadcast capability. Emergency lighting: 38 battery unit replacements (90-minute rated), 24 new photoluminescent exit signs at corridor decision points. Cable: approximately 1.8 km new cable installed; 1.2 km existing cable reused after insulation resistance testing.
Phased cutover: 4 phases over 9 weeks, all night work on patient floors (10 PM – 5 AM). Testing: each phase functionally tested before next phase commencement. Final witnessed test: full-building alarm activation with voice evacuation, fire door release, and lift homing verified in presence of Bhuj fire authority inspector.
