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.
|
|
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.
|
|
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.
|
|
. 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.
