FIX800, an installation type oxygen concentration meter for safety use in closed spaces in disaster prevention rooms of public institutions

Received order for FIX800 3SET installation type gas meter for worker safety in disaster prevention room (closed space) in public institution in Paju City. It is a set with electronic display board so that the status of disaster prevention room can be viewed at the entrance.

The FIX800 product is a custom-made gas meter that can be equipped with a single to up to five gases simultaneously according to user requests. You can immediately check real-time measurement values ​​through the external display.

There is an installation hole on the back of the product so it can be mounted directly on the wall.

When measuring multi-gas, a separate bracket is required for installation due to the size of the sensor unit. However, in this case, for the convenience of future maintenance, a bracket was ordered together even though it is a single gas. Maintenance refers to a situation that requires inspection by an expert, such as product calibration or sensor replacement. Since the product must be separated and sent to the engineering department, the convenience of attachment and detachment was increased by using a bracket rather than installing directly on the wall.

This is a custom-made status board that corresponds 1:1 with FIX800. FIX800 includes relay operation, analog output (4-20ma), and digital communication (RS485) without additional options. This order is a case of transmitting data to the status board using RS485 communication for communication stability, and 485 is used in the majority of sales.

The color of the text on the status board changes when the gas concentration changes according to user designation or laws. You can add sound, light, and warning lights by adding the option.

The wiring between the meter and the electronic sign board is very simple. If you supply 220V to the electric sign board, the electric sign board provides 24V power to the meter. In other words, it works right away by connecting only 4 wires of 4WIRE (communication AB power +-). We provide a wiring and installation manual as shown in the photo below.
