Integrating Commercial Fire Alarm, PA & CCTV Systems for Factories in Rajasthan

Scope and Compliance Overview

Factory safety projects in Rajasthan must satisfy National Building Code (NBC) 2016 Part 4. The code mandates addressable fire detection, audible evacuation, and coordinated visual monitoring. KAS Info Tech, ISO 9001:2015 certified and a trusted partner for Rajasthan Police and Indian Railways, delivers end‑to‑end integration that meets these statutory requirements.

1. Addressable Smoke & Heat Detector Loop Wiring

Addressable loops reduce cabling by allowing up to 128 devices per panel while providing zone‑specific fault diagnostics.

1.1 Wiring Topology

• Star‑bus topology for Hikvision DS‑SMD‑A or CP Plus AD‑SM detectors.
• Use Category‑6 shielded twisted pair (STP) for power and data, rated 300 V.
• Terminate each loop at the fire alarm control panel (FACP) with a 24‑bit address module.

1.2 Cable Sizing Example

All cable runs must be placed in conduit or cable trays compliant with IS 3832.

1.3 Cost Snapshot (₹)

• Addressable detector (smoke/heat) – ₹2,200 each.
• STP cable (1 km, 2.5 mm²) – ₹45,000.
• Termination module (24‑bit) – ₹12,500.
• Installation labor (per detector) – ₹800.

Typical 64‑device loop for a 2,500 m² factory totals ≈ ₹3.2 Lakhs.

2. Automated Public Address (PA) Announcements

When a fire zone trips, the FACP sends a relay pulse to the PA controller. KAS Info Tech integrates Matrix M‑PA‑500 units with pre‑recorded multilingual evacuation messages.

2.1 Trigger Logic

1. Detector loop fault → Zone ID sent to FACP.
2. FACP activates zone‑specific relay (24 V DC).
3. Relay energizes Matrix PA input.
4. PA controller plays the assigned audio file (e.g., “Fire in Zone 3 – Evacuate via Exit B”).

2.2 Speaker Placement

• Minimum 85 dB SPL at 3 m distance.
• One speaker per 150 m² floor area; staggered for overlapping coverage.

2.3 Pricing (₹)

• Matrix PA‑500 unit – ₹28,000.
• Ceiling‑mount speaker (4 in) – ₹3,500.
• Wiring (2‑core, 2.5 mm²) – ₹12 per meter.
• Programming & testing – ₹5,000 per zone.

For a 4‑zone factory (≈ 20 speakers) the PA budget is ≈ ₹4.1 Lakhs.

3. CCTV PTZ Preset Call on Fire Sensor Trip

Linking fire detection to CCTV provides instant visual verification. The integration uses a Modbus TCP command from the FACP to the NVR, which then drives a PTZ camera to a predefined preset.

3.1 Device Requirements

• PTZ camera with Modbus support – Hikvision DS‑2DE4A425IW‑DE (₹28,000).
• Network Video Recorder (NVR) with 8‑port PoE – CP Plus NVR‑8‑POE (₹22,000).
• FACP with Modbus output – KAS‑FACP‑X200 (₹85,000).

3.2 Integration Steps

1. Assign each fire zone a unique Modbus address.
2. Configure NVR to map Modbus address → PTZ preset (e.g., Zone 2 → Preset 5).
3. Program FACP to send a single‑coil “ON” command on zone alarm.
4. Test by simulating a detector trip; PTZ should swing to preset within 2 seconds.

3.3 Cost Overview (₹)

• PTZ camera – ₹28,000 each (2 cameras for dual‑zone coverage).
• NVR – ₹22,000.
• Modbus gateway (if required) – ₹9,500.
• Installation & commissioning – ₹1,200 per camera.

Total CCTV‑PA‑Fire loop integration for a 3‑zone plant ≈ ₹6.5 Lakhs.

4. End‑to‑End Project Checklist

1. Obtain NBC Part 4 compliance clearance from local authority.
2. Finalize detector layout and zone mapping.
3. Procure addressable detectors, STP cable, PA units, speakers, PTZ cameras, NVR, and Modbus gateway.
4. Run conduit‑protected cable trays for power & data.
5. Terminate loops at FACP; verify address allocation.
6. Program PA messages in Hindi, English, and regional dialects.
7. Configure NVR‑PTZ preset table linked to Modbus addresses.
8. Conduct functional test: detector → PA → PTZ → video feed.
9. Document as‑built drawings and submit to fire department.
10. Schedule 24/7 monitoring contract with KAS Info Tech (Helpline +91 80581 22233).

5. Real‑World Deployment Highlights

KAS Info Tech recently secured 850+ police stations across Rajasthan, integrated high‑speed surveillance at Alwar Railway Station, and deployed PA‑CCTV‑Fire loops in DMart warehouses. The same OEM partners (Hikvision, CP Plus, Matrix) and ISO‑driven processes ensure repeatable quality for factories.
