- Q:How do you connect air sampling, smoke detectors and fire engines?
- Air sampling smoke detectors (Standard Name: air breathing smoke detector) can generally form a network of their own
- Q:Who knows the distance between the smoke detector and the shower head?
- The smoke detector is by monitoring the concentration of smoke to achieve fire prevention, smoke detectors, the internal use of ion smoke sensor, ion smoke sensor is a kind of advanced technology, stable and reliable operation of the sensor, is widely used in all kinds of fire alarm system, fire alarm performance is far better than the gas sensing resistance type.
- Q:What is the cumulative depreciation of smoke alarms?
- (1) the double declining balance method is a method of calculating fixed assets depreciation according to the book balance of fixed assets and double linear depreciation rate at the beginning of each period without considering the residual value of the fixed assets. This is a method of accelerated depreciation:Annual depreciation rate = 2 / depreciation period * 100%Monthly depreciation rate = annual depreciation rate of 12.Annual depreciation = book value of fixed assets * annual depreciation rateWhere the fixed assets are depreciated by double declining balance method, the net value of the fixed assets shall be averagely amortized within two years before the depreciation period of the fixed assets.(2) sum of years methodAlso called the total life method, is the original value minus net fixed assets net value after multiplied by a year by year reduction in annual depreciation score calculationAnnual depreciation rate = total number of years of useful life / expected service lifeAnnual depreciation rate = (estimated service life - useful life) / estimated service life * (estimated service life -1) /2*100%Monthly depreciation rate = annual depreciation rate /12Monthly depreciation (= fixed assets - the expected net salvage value) * month depreciation rateUsually use average method like Shenzhen smoke alarm, relatively simple.
- Q:What's the smoke alarm in the house every few seconds?
- From the internal principle, the smoke alarm is by monitoring the concentration of smoke to achieve fire prevention, such as internal Long Xin smoke alarm by ion type smoke sensor, it is a kind of advanced technology, stable and reliable operation of the sensor, is widely used in all kinds of fire alarm system, fire alarm performance is far better than the gas sensing resistance type.
- Q:Installation method of Gulf smoke alarm
- Drill two holes at two holes.Insert two plastic waist nails into the two holes, then close the mounting support to the wall.Plug in and fasten the mounting screws until the mounting bracket is firmly removed.
- Q:Can the fire smoke alarm be sealed? Don't want it to call the police. It's too noisy
- Three is the switch / relay smoke sense (multi line smoke sense, /4 line smoke feeling), mainly used for security system matching (anti-theft, monitoring, fire rolling system, etc.).This kind of smoke sense factory manufacturers are usually with a buzzer, and if you do not need sound, you can ask manufacturers to remove the buzzer. In fact, such products are also exported without a buzzer.
- Q:What's the difference between a gas alarm and a smoke alarm?"
- Smoke alarm, a kind of alarm, common in life, the world's most commonly used smoke alarm, is the photoelectric smoke alarm and ionization smoke alarm.
- Q:How can I makeHow can I make the smoke alarm not alarm? the smoke alarm not alarm?
- You're carrying a cigarette smoke detector. It's really smart, but you can try to cut off its power cord so you don't call the police when you smoke.
- Q:Which is a good home fire alarm?
- Rapid alarm: in the detection of fire within 5 seconds, fast treble sound and light alarm, to remind the sleeping family, get up quickly, fire, deal with, to prevent small fire cause big accident;
- Q:Can smoke detectors be self checking?
- Generally depends on where your smoke detector is installed, and if it is in the room, its range is your entire room, it has a wide range, as long as there is smoke detected, it will alarm.
