How to choose a handheld Walkie-talkie for the fire department?
2024-07-18
When choosing a handheld walkie talkie for the fire department, you need to consider the following key factors:
1.Use environment:
The fire walkie talkie should have a high protection level, such as IP67, to ensure that it can still work properly in harsh environments.
2.Frequency range:
The frequency range of the fire walkie talkie is usually 400-470MHz, which is the core frequency band of the fire walkie talkie. In addition, the walkie talkie should have the function of manually and continuously adjustable frequency, so that the frequency used by the professional rescue team can be quickly set in an emergency.
3.Transmit power:
The transmit power should be adjustable so that low-power transmission can be used as much as possible to reduce power consumption while ensuring communication.
4.Explosion-proof level:
Fire explosion-proof walkie talkies must comply with the corresponding explosion-proof standards, such as international IECEx, European ATEX, US UL, Russian EAC EX, etc. Choose the appropriate explosion-proof level according to the hazard level and gas category of the use environment.
5.Explosion-proof levels are usually divided into Class, Division, and Group:
- Class: Class I represents volatile gasoline (and other petroleum oil and gas products)/air mixtures; Class II represents dust/air mixtures; Class III represents suspended solids/air mixtures.
- Division: Division 1 refers to places where explosive gas environments exist during normal operation; Division 2 refers to places where explosive gas environments exist during abnormal operation or equipment failure.
- Group: Group A is acetylene gas, Group B is hydrogen, Group C is ethylene, ether, etc., Group D is propane (liquefied petroleum gas), acetone, ammonia, benzene, etc., Group E is metal dust, Group F is carbon dust, and Group G is grain dust.
6.Knob:
It is very important to find a radio with knobs that are easy to use with gloves. It is best to choose a radio with large knobs, which makes it faster and easier to switch channels. The channel knob should be clearly identifiable and have a sense of resistance to let the user know if they are using the correct knob. It is best to test the radio before purchasing to see if you can use the knob easily while wearing gloves.
7.Slip resistance:
As a firefighter, you need to move around a lot. To cope with these situations, it is wise to choose a model with a non-slip rubber texture. Models with slightly more texture are also better because you will be moving around a lot and will be in many emergency situations, and you don’t want to lose your radio. In addition, you want the radio to be sturdy in case of a drop.
8.Reinforced glass screen:
During an emergency, you may be in dangerous environments, so you need a sturdy glass screen. Don’t choose a radio with a screen that can be easily scratched or cracked, otherwise the radio will be meaningless. At the same time, it is best if the screen is large enough to be able to quickly view the information on the radio.
9.High-quality microphone:
The most important thing is to look for a good quality microphone. You need a model with a clear and loud microphone/speaker. Sometimes in situations with a lot of smoke, it is difficult to see which end of the microphone you are talking to. Therefore, you should look for a model with speakers on both ends of the microphone or in the front and back.
These are just some suggestions for choosing the best fire department radio. You need to look for a radio that is sturdy and has features that ensure the safety of firefighters. For more information on different models, you can consult a professional or check the prices.
10.Safety functions:
Some models have useful safety features, such as a large emergency button. This allows you to quickly press the button without having to fumble around on the radio. In dangerous situations, you need to sound the alarm quickly. Another useful feature is the "firefighter down" function, which transmits a signal when a firefighter is immobile for a long time. Some radios even have GPS technology to locate missing firefighters. This is very helpful in emergencies such as forest fires. In addition, emergency call functions, playback functions, positioning functions, etc. are available to improve rescue efficiency and safety. It has a one-button alarm evacuation function, supports full recording and recording file export functions.
11.Battery life:
The walkie-talkie needs to have a long standby time and a long talk time to ensure that it can still be used normally in the event of a power shortage. It is recommended to choose a walkie-talkie with a large battery capacity and a long standby time.
12.Protection level:
