Fire Alarm System

Fire causes destruction. Only effective and timely safety measures will ensure that our site will remain protected and safe. We must use fire alarm systems to avoid fire hazards. The system is used to detect and warn people through visual and audio appliances when smoke or fire is present. These alarms may be activated from smoke detectors and heat detectors. They may also be activated via Manual fire alarm activation devices such as manual call points or pull stations. We at Limra, partner with leading manufacturers to provide various fire alarm solutions across a variety of industries. We coordinate closely with owners, architects and contractors to ensure the best solution for reliability and survivability, all on time and on budget.

Our Fire Alarm And Detection Solutions Include

Smoke Sensors:
A detector or a sensor that senses smoke and acts as an indicator of fire. It basically issues an audible or a visual signal to the fire alarm control panel in case of fire.

Heat Sensors:
A heat detector is a device designed to respond when thermal energy of fire increases the temperature of heat sensitive element.

Multi-criteria Detectors:
Multi-criteria devices use multiple sensors to detect multiple conditions and sense a wider range of fires with greater accuracy.

Optical beam smoke detector:
A device that uses a projected beam of light to detect smoke across large areas, typically as an indicator of fire. They are used to detect fires in buildings where standard point smoke detectors would either be uneconomical or restricted for use by the height of the building.

Manual Call Point:
Manual alarm call points are designed for the purpose of raising an alarm manually once verification of fire or emergency condition exists by operating the push button or break glass to raise an alarm signal.

Fire Alarm Hooter:
The Fire Alarm Hooter is a device which produces sound when the sensor senses any kind of fire activity.

Addressable Fire Alarm Panel

Every device connected to the addressable system has its own unique address. When a fire is detected, the device’s address shows up on the main control panel, telling us exactly which device has been activated. This will enable us to find the exact location of a fire and extinguish it quickly. Addressable fire alarm control panels include some of the following:

NFS-320: It is designed specifically for small applications with features that minimize installation time, enables faster response times, and simplify maintenance and usability.

  • Intelligent Devices: 3180 total devices (159detectors/159modules) per SLC
  • Voice Evacuation available
  • 6amp total system power

Cconventional Fire Alarm Panel

  • With a conventional system, there is no way of pinpointing the exact location of the fire.
  • By wiring your building into different zones, one can get a general idea of where the fire is.
  • For instance, if you have two floors, you could wire the first as ‘zone 1’ and the second as zone 2. So if a fire occurs in zone 1, you know that the fire is somewhere on the first floor.

Conventional fire alarm control panels include some of the following:
