Toluene concentration alarm

The product consists of a controller, detectors, signal cables, etc., and is wall-mounted. The controller is strictly designed and manufactured in accordance with GB16808-97 "Technical Requirements and Test Methods for Combustible Gas Alarm Controllers," and has been qualified by the National Fire Electronic Product Inspection Center; the detector is strictly designed and manufactured in accordance with GB15322-2003 "Technical Requirements and Test Methods for Combustible Gas Detectors." The detection element inside the detector uses imported specialized gas sensors, featuring high sensitivity, strong stability, long service life, and low power consumption. This device also has the function of controlling peripheral equipment (such as exhaust fans and safety valves). When an alarm occurs, it can output a signal voltage to turn on the exhaust device and close the safety solenoid valve. After the leakage fault is eliminated, the mute button can be pressed to stop the alarm sound. After pressing the reset button, the safety solenoid valve opens and the system re-enters the monitoring state. Users can select different product models based on the different gases to be detected. It is divided into two specifications based on the number of channels: one to four channels, and four to eight channels. The monitoring environment for each detector is 8-15 square meters. Users can select different specifications based on the area of the monitored environment; if the user's needs exceed the capacity, multiple units can be used in combination. The product has a built-in battery that can automatically switch over in the event of a power grid failure, providing backup power for more than 2 hours.
