1. Conventional Smoke and Heat Detectors

　　The installation spacing of smoke detectors and heat detectors should be determined based on the protected area and coverage radius of the detectors. Generally, for smoke detectors, the protected area is 80 square meters when the height is greater than 6 meters and less than or equal to 12 meters, and 60 square meters when the height is less than or equal to 6 meters. For heat detectors, with an installation height of less than or equal to 8 meters, the protected area is typically between 20 to 30 square meters.

　　2. Infrared Beam Smoke Detectors

　　The vertical distance from the optical axis of the infrared beam smoke detector to the ceiling should be between 0.3 to 1.0 meters, and the height from the ground should not exceed 20 meters. The horizontal distance between adjacent pairs of infrared beam smoke detectors should not exceed 14 meters. The horizontal distance from the detector to the side wall should not exceed 7 meters and should not be less than 0.5 meters. The distance between the emitter and receiver of the detector should not exceed 100 meters.

　　3. Manual Fire Alarm Buttons

　　At least one manual fire alarm button should be installed in each fire compartment, and the distance from any location within a fire compartment to the nearest manual fire alarm button should not exceed 30 meters. Manual fire alarm buttons should be installed at the entrances and exits of public activity areas. They should be placed in obvious and easily accessible locations. When mounted on the wall, the bottom edge of the button should be positioned at a height of 1.3 to 1.5 meters above the ground and should be clearly marked.

　　The above are the installation requirements for automatic alarm systems compiled by automatic alarm system manufacturers. We hope this information is helpful to you. For further information on automatic alarm systems, please feel free to contact us.
