Nearly 30,000 smoke detectors and sensors will be installed at the new terminals of the Indira Gandhi International Airport. A massive modernization plan is underway at the international airport.

These detectors, being purchased from a US company, would automatically send signal to the fire control panel upon detecting smoke and thereafter to the alarm hooter prompting security officials to activate safety and evacuation operations. The whole setup will cost a few lakhs of rupees while the actual cost was not revealed by the company.

The alarm hooter and detectors at the Delhi airport, which is being currently spruced to international standards, will serve to alert the people in the building, including both air passengers and employees.

Since 2002, the market for security and fire protection products has grown up by nearly 47 per cent.
