Sampling method for engineering installation of inspiratory smoke fire detector

The inspiratory smoke fire detector has been used more and more because of its high sensitivity, flexible construction and installation, and breakthrough in some concepts of applicable places.

However, as a special type of smoke detector, its installation and use has its own particularity.

Sampling on the ceiling, the sampling pipe is concealed, and the pipe can not be seen when the head is raised in the space. This kind of installation is beautiful, with ceiling and easy to implement at the initial stage of equipment installation. What we actually look up at is a one dollar coin size logo sampling head. The sampling head and the sampling pipe are connected by hose.

Pipe laying sampling method is more common, the advantage is that the construction is convenient and simple, and there is no need for other accessories, and the sampling hole can be directly opened on the sampling pipe.

Return air sampling. Because of the air flow, the smoke will follow the air flow to the return air port. The sampling pipe is arranged at the return air port, and the smoke can be collected and detected quickly. Smoke can be detected quickly by air flow. If there is air circulation in the site, it needs to be set.

The under floor sampling is suitable for the space detection of the under floor line of the elevated floor. Because of the relative sealing under the floor, the smoke is not easy to be detected. When the sampling pipe is arranged under the floor, the smoke anomaly in this area can be detected effectively.

Due to the height and barrier of the space, other types of smoke detectors are not suitable for the elevated warehouse. More and more high-rise warehouses have begun to use the inspiratory smoke fire detector because of its flexible step pipe method and high sensitivity.

The elevated warehouse adopts layered pipe layout, and layered step pipe can solve the problem of high smoke dilution in space or large dilution in space.

The inspiratory smoke fire detector has been used more and more because of its high sensitivity, flexible construction and installation, and breakthrough in some concepts of applicable places.

However, as a special type of smoke detector, its installation and use has its own particularity.

What we actually look up at is a one dollar coin size logo sampling head. The sampling head and the sampling pipe are connected by hose.

The installation height of the inspiratory smoke detector is suitable for the convenience of installation, inspection and maintenance.

There is a great fire risk in the electrical cabinet, and because the electrical cabinet is relatively sealed, when the traditional point type smoke fire detector detects and alarms, the fire has often spread to multiple electrical cabinets. Inspiratory smoke fire detector can effectively detect the potential fire hazard of the electrical cabinet, and it is a real early warning, which is often detected when the cable is abnormally hot.
