What are the requirements for the installation company to install the fire monitoring smoke rod alarm?

A, ordinary smoke temperature detector

The installation distance between smoke detector and temperature detector should be determined according to the protection area and radius of the detector. Generally, the protection area of smoke detector is 80m2 when the height is more than 6m and less than or equal to 12m, and 60m2 when the height is less than or equal to 6m. The installation height of the temperature detector is less than or equal to 8m, and the general protection area is 20-30m2.

Second, infrared beam smoke detector

The vertical distance from the beam axis of the infrared beam smoke detector to the ceiling should be 0.3- 1.0m, and the height from the ground should not exceed 20m.

The horizontal distance between two adjacent infrared beam smoke detectors should not be greater than 14m. The horizontal distance from the detector to the side wall should not be greater than 7m or less than 0.5m The distance between the transmitter and receiver of the detector should not exceed100m.

Third, the manual fire alarm button

Each fire zone shall be provided with at least one manual fire alarm button, and the distance from any position in the fire zone to the nearest manual fire alarm button shall not be greater than 30m. Manual fire alarm buttons should be set at the entrances and exits of public venues.

The manual fire alarm button should be set in an obvious and easy-to-operate position. When installed on the wall, the height of its bottom edge from the ground should be 1.3- 1.5m, and it should be clearly marked.
