Matters needing attention in purchasing fire alarm
1. Determine whether the gas alarm products to be purchased have product qualification. This is a necessary document for future inspection by the Safety Supervision Bureau. The alarms or detectors produced by regular manufacturers have relevant product qualifications, including product type approval certificate, explosion-proof certificate, measuring instrument certificate, etc. And there are inspection reports. All alarm manufacturers generally have relevant inspection reports.
2. Make clear whether the required product is a gas alarm or a detector, both of which can detect flammable and toxic gases and give an alarm to prevent the occurrence of danger. The difference lies in the way they are used. Combustible toxic gas alarm is fixed and installed, which is divided into two parts: controller and detector. The controller and the detector are connected by cables. The branch alarm needs to be connected by three-core wire, and the bus type needs to be connected by four-core wire. According to the site situation, it depends on whether the cable needs to be sheathed with pipe fittings. If sleeve is not needed, it is recommended to use shielded cable.
The working voltage of the controller is 220 volts AC, and the working voltage of the detector is 24 volts DC, which is directly powered by the controller. The combustible toxic gas detector is portable and portable. According to different product models and different power supply methods, it can be roughly divided into built-in rechargeable batteries and replaceable ordinary alkaline batteries or liquid batteries.
