IS 2189:2006 is the Indian Standard (BIS) for selection, installation and maintenance of automatic fire detection and alarm system. This code establishes the requirements for the planning, design, selection, installation, and maintenance of automatic fire detection and alarm systems in buildings. It provides comprehensive guidelines on detector spacing, zoning, alarm sound levels, and power supply to ensure reliable early warning in the event of a fire.
Provides guidelines for the design, installation, testing, and maintenance of automatic fire detection and alarm systems.
Key limits for detector spacing, manual call point placement, zoning, sounder levels, power backup, and cabling.
| Reference | Value | Clause |
|---|---|---|
| Max Coverage Area (Smoke Detector)— For smooth, flat ceilings up to 5m height. Reduces with height. | 80 m² | Annex C (Table C-1) |
| Max Spacing 'S' (Smoke Detector)— For smooth, flat ceilings. Max side of any bay is 10.7 m. | 9.1 m | Annex C (Table C-1) |
| Max Coverage Area (Heat Detector)— For smooth, flat ceilings up to 7.5m height. Reduces with height. | 50 m² | Annex C (Table C-1) |
| Max Spacing 'S' (Heat Detector)— For smooth, flat ceilings. Max side of any bay is 8.5 m. | 7.5 m | Annex C (Table C-1) |
| Min Distance from Wall (Detectors)— Minimum distance from any wall, partition or obstruction. | 500 mm | Cl. C-2.2 |
| Mounting Range from Ceiling (Detectors)— Sensing element must be within this range below the ceiling. | 25 mm to 600 mm | Cl. C-2.1 |
| Obstruction Rule (Shallow Beams)— If beam depth is less than 10% of ceiling height, it can be ignored. | Depth <10% of ceiling height | Cl. C-2.4 |
| Obstruction Rule (Deep Beams)— If beam depth is more than 10% of ceiling height, treat as a wall. | Depth >10% of ceiling height | Cl. C-2.4 |
| Mounting Height (Manual Call Point)— Measured from the finished floor level to the center of the MCP. | 1.4 m | Cl. D-2 |
| Max Travel Distance (Manual Call Point)— No person should have to travel more than 30 m to reach an MCP. | 30 m | Cl. D-1 |
| Min Sound Level (General Areas)— Or 5 dB(A) above any other noise likely to persist for more than 30s. | 65 dB(A) | Cl. E-2.1 |
| Min Sound Level (Sleeping Areas)— Measured at the bed-head with all doors closed. | 75 dB(A) | Cl. E-2.1 |
| Max Floor Area per Zone— A single fire alarm zone should not cover more than one floor. | 2000 m² | Cl. 6.2.2 |
| Max Search Distance in a Zone— To locate the fire from the zone entry point on the control panel. | 60 m | Cl. 6.2.2 |
| Max Devices per Zone— Maximum number of detectors and manual call points in a single zone. | 32 | Cl. 6.2.2 |
| Min Standby Power Duration— Battery backup must operate the system in quiescent state for 24h. | 24 hours | Cl. 5.3.2.2 |
| Min Alarm Duration (on Battery)— After 24h standby, must power all sounders for at least 30 min. | 30 minutes | Cl. 5.3.2.2 |
| Min Cable Conductor Size— For solid copper conductors used for system wiring. | 1.5 mm² | Cl. 5.4.2 |
| Required Cable Type— Cables should be fire resistant type, conforming to relevant standards. | Fire Resistant | Cl. 5.4.2 |
| Maintenance Frequency (Panel Check)— Check control panel for correct operation and fault indicators. | Weekly | Annex G (Table G-1) |
| Maintenance Frequency (Zone Test)— Test at least one detector or MCP in each zone to check panel response. | Quarterly | Annex G (Table G-1) |
