basisGB50493-2019standard,In order to better protect the safety of life and property,Our group company specializes in developing a measurement intelligent area combustible and toxic gas sound and light alarm control system, which is an on-site device.
Flammable on-site/Toxic gas detector,On site installation of a certain area,The installation location is relatively concentrated12Road gas detector,Information input into this system device. The intelligent area alarm control device is installed on the edge of the main channel or around the area, as well as on the periphery of the workshop and central control room. When the gas concentration exceeds the limit on site, the device will trigger a secondary alarm,Quickly evacuate the on-site staff as soon as possible. At the same time, it can push mobile terminal alarms. Effectively control the occurrence of accidents,Protecting the safety of life.
When a traditional workstation or control room detects an accident alarm,Only intelligent area alarm control device,Can evacuate quickly and directly.(Because the central control room does not know which workers are inspecting the equipment at which location,Notification is also not fast and accurate)
characteristic
When the signal from the combustible and toxic gas sensor is input to the local device, 12/8/4/1When the concentration in the channel and other circuits exceeds the hazard standard,The control system outputs a signal to the corresponding indicator light on the control box of this device,Activate the explosion-proof area sound and light alarm,issue118DBintenseAlarm soundandRed flashingWarning lights, repair technicians immediately eliminate the leakage of flammable and toxic gases on site according to the circuit indicator lights, effectively controlling the occurrence of accidents.
The maintenance specialist arrived at the site and turned off the sound alarm,To avoid affecting the work of other personnel, the red flashing warning lightAfter the accident has been eliminated,The controller can only be reset,Red flashing warning lightAutomatic release.
The equipment has tests/Self checking function, capable of detecting the quality of the system and equipment itself.
The alarm signal sound level of the regional alarm should be higher than110dBAAnd away from the alarm1mThe total sound pressure value shall not exceed120dBA.
Regional alarm system access1、4、8、12The on-site gas detector in the road channel provides contact signals4-20Milliampere signalRS485、Wi-Fi、5GIt is also acceptableGDSSystem signal.
Multiple output modes: twelveRoad channel analog quantity4-20mA、RS485、4G(5G)、Wi-FiAnd wireless ad hoc networks, Internet of Things, local area networks, and wired networksRJ45,Remote network monitoring is possible.
