Description
1. Fire alarm control panel
The fire alarm control panel is used in the fire alarm system to receive, show and transmit fire alarm signals, and can send control signals to other control indicating equipment.
2. Fire detector
Fire detector is a device that checks and detects fire in the conventional fire alarm system. The fire detector is the “sensory organ” of the system, its function is to monitor whether there is a fire nearby. Once there is a fire, the detector will convert the physical characteristics of fire, such as heat, smoke, gas and radiant light, into electrical signals, and immediately send them to the fire alarm control panel.
According to the ways to collect fire on the site, the fire detectors can be divided into:
2.1 Smoke detector
Smoke detector is a fire detector that uses a small smoke sensor to respond to the smoke aerosols (solid or liquid particles) flowing in the surrounding air resulting from combustion or pyrolysis. According to its working principles, the smoke detector can be divided into ionic type and photoelectric type.
