Product Description

Products Description

  In automatic mode, when any detector senses a fire, it immediately transmits a signal to the control panel. The control panel then activates the audible and visual alarm devices, starts the exhaust fans, disconnects non‑essential power supplies, and sends a command to recall all elevators. If a person discovers the fire, they can press a manual call point to trigger the same sequence.

  For areas protected by a gas‑based fire suppression system, the release sequence begins only after two independent detectors have been activated. Once this condition is met, a pre‑determined delay timer starts. After the delay elapses, the extinguishing gas is released, and the release indicator lights illuminate to clearly warn people not to enter the protected area. All these functions work together to ensure fast fire detection and safe occupant evacuation.

1. Detection Layer (Sensors)

The detection layer acts as the sensory system of the fire alarm installation. It includes smoke detectors, heat detectors, and combined smoke‑and‑heat detectors.

  • Smoke detectors sense changes in air caused by combustion and are ideal for offices, hotels, and corridors.

  • Heat detectors monitor temperature increases and are well suited for kitchens, car parks, and plant rooms.

  • Combined detectors use both smoke and heat sensing to reduce false alarms, making them a preferred choice for hospitals and premium commercial buildings.

  • Beam smoke detectors are recommended for large‑volume spaces such as warehouses, atriums, and sports stadiums.

  • Flame detectors should be used in high‑risk areas, including oil depots, fuel storage zones, and chemical plants.

2. Input Layer (Manual and Monitoring Equipment)

This layer enables manual initiation and external equipment monitoring. It consists of manual call points, input modules, short‑circuit isolators, and fire telephone sockets.

  • Manual call points are installed near exits, staircases, and common areas, allowing anyone to manually trigger an alarm.

  • Input modules receive status signals from external devices, such as water flow switches, pressure switches, and control valves.

  • Short‑circuit isolators automatically disconnect faulty sections of the loop, ensuring the rest of the system remains operational.

  • Fire telephone sockets enable direct communication between firefighters and the central control panel during an emergency.

3. Control Layer (The “Brain” of the System)

The control layer is the central intelligence of the entire fire alarm system. Its main components are the Fire Alarm Control Panel (FACP) and the Gas Suppression Control Panel.

  • The FACP receives signals from all detectors and modules, decides when to generate alarms, and activates all connected field devices.

  • The Gas Suppression Control Panel is specially designed for FM200, IG541, CO₂, and other clean agent systems. It supports functions such as delay before releasemanual/automatic mode selection, and pressure switch monitoring.

  • Additional control devices include repeater panels for displaying alarms on different floors and fire broadcast control panels for playing pre‑recorded or live evacuation messages.

. Execution Layer (Alarm and Action Equipment)

The execution layer carries out the commands issued by the control panel. It includes alarm sounder‑strobes, output modules, fire alarm bells, and gas release indicators.

  • Alarm sounder‑strobes produce high‑audibility sounds and flashing lights to clearly alert occupants to evacuate.

  • Output modules control external equipment such as exhaust fans, fire dampers, power cut‑off relays, and elevator recall units.

  • Fire alarm bells offer a cost‑effective solution for conventional or smaller systems.

  • Gas release indicators are mounted at the entrance of each protected area. They illuminate when gas is about to be released or has already been discharged, providing a clear visual warning not to enter.
