Automatic fire alarm system management and maintenance of fire alarm system is a State-of-the-art technical facilities, fire not only prices high, and the use of performance is strong, so the user upon installation, it is necessary to strengthen the management and maintenance of in fire extinguishing full role. Management and maintenance of automatic fire alarm system please note the following : (a) strengthen the automatic fire alarm system technology archives management of some units overlook on the automatic fire alarm system of the archives of finishing and saved. Late "system" archives of finishing and save a very important role in , not only to provide information on the fire service, for the "system" and its management and maintenance important also. Therefore must be noted: in the automatic fire alarm system installation has been completed, the user should be in the design, construction attire, units surrendered for system construction drawings and technical data and installation technology system records, various parts of the test records, reports, commissioning and acceptance report be whole, to establish technical archives, safekeeping, for the query. At the same time, in the "system" prior to opening of transportation should establish the appropriate procedures, on-duty staff duties, watch records, in display system protected buildings location plan or simulation, system operation in the registration form, repair equipment dimension records to enable managers to observe in their work. (2) trigger device in use common problems and troubleshooting for detecting device for environmental conditions change, not applicable, you should by design, the timely replacement of the construction sector. If the room to the kitchen, the boiler house, boiling water, generator room when they should be changed to smoke-detector temperature sensor type detector. As far as determination of smoke-detector temperature of environment in General 50 ℃ around, or they may be faulty, while exploring the fixed temperature measuring device actions of rated temperature should be higher than the ambient temperature 10 ° c-35 ℃. To prevent outside interference or accidental damage. For detectors is not only to prevent cigarettes, similar to dust and aerosol, small animal intrusion, water vapor condensation, icing, and other external natural factors taken as a result of false positives, but also to prevent man-made factors such as shelves, storage racks or the placing of equipment, partition, separated on the detector and manual alarm button. Decoration for second place, it is necessary to pay attention to check the original detectors and manually , alarm button is intact, if available, the line. If you have this problem you must retake or replacement, or alarm malfunction alarm occurs. Note on probe cleaning and storage of spare parts. Probe inputs after running vulnerable to the ring, the accumulation of dust pollution of the environment, so that reliability reduces false positives or false negatives, and affect the normal operation. Therefore, on its regular cleaning and maintenance is essential and very important. Clear via accumulation is dust or dirt will regain the best sounding effect. If dust and Department of branch dirt surrounded by an ion detector smoke Chamber, the smoke particles may not reach the ionization chamber, this measured only on the device will become less sensitive; if the dust and dirt that radioactive source patch isolation, electric air away from the level decreases, Ion Detector becomes more sensitive and prone to produce false positives. Then such as various photoelectric detector, dust and greasy dirt accumulation will reduce the light intensity in various , light scattering detector will become less sensitive; and various optical attenuation type probe will become more sensitive spirit. For flame Detector sensitivity is also due to the lens on the accumulation of dust and dirt ringing without shadow. All this shows that regular cleaning is necessary. In order to maintain good performance and positiveOften, you should run the probe opened two years later, every three years all cleaning again.
In the automatic fire alarm system construction acceptance "(hereinafter referred to as the" standard ")
Chapter 4, section III" system ", on the fire detector inspection and testing as well as
cleaning done a clear
provisions: 1. quarterly special instrumentation batches of test probes
action and indeed recognize light show.
2. annual applying specialized testing equipment to test the installation of detectors.
3. fire detectors running 2 years after every 3 years all cleaning again,
response and thresholds and other necessary functions test, candidates may continue to use the unqualified
guard who strictly to reinstall.
(3) alarm device
of check in to check on a fire detector smoke with special tools
for practical exercises. When fire detectors in after receiving a smoke alarm acknowledgement lights,
the detection is working properly, at the same time to the alarm controller issued a fire signal. Also check
no clock is, there is no fire time records. Inspection, the person on duty shall promptly
equipment for silencers, reset in case of long make the device component is damaged.
(4) the fire water system
checked fire water system mainly by the fire hydrant system and automatic sprinkler fire
water supply system of two components.
1. fire hydrant system maintenance
management: hydrant systems typically include municipal fire hydrant system and building fire
of suppository water supply system. Its maintenance management should be
: improving citizens ' awareness and legal concepts of fire, no damage, occupy, bury fire hydrant.
This is one of the most fundamental. The FSO People's Republic of China article 29 of regulation
clearly: "all units and individuals are responsible for protecting fire facilities ... To bury
and occupy ... "fire water.
Enhance fire hydrants and fire water pipe of inspection and maintenance, timely and clear
around the hydrant debris, check there is no rust leaking fire hydrant, rubber washer for fire protection design and so has
seal for damage or loss, whether of gate opening hydrant flexibility, time the necessity should
stem and lubricating oil. In addition, on indoor hydrant you should also check the box of water gun fire hydrant, hoses, etc
equipment is not complete, there is no mold rot hose, problems, correct.
Do a fire hydrant winter protection to prevent the fire hydrant water froze and blocked pipeline.
Especially Northern cold areas, winter before shall take the necessary measures of antifreeze.
Maintain the integrity of the hydrant logo stand out. On the parking lot around the outdoor
suppository with fire, you should set aside a certain amount of scope creation flags that prevent drivers will be parked in the fire hydrant
impact at and used underground fire hydrant, its well cover more should have significant signs
to distinguish them from underground pump adapter, avoid fire out of the chaos in the busy.
Sampling of effluent from the fire hydrant at any time. On the important parts of a fire hydrant should
rows one at a time into the water; for non-key parts of the fire hydrant can fire hydrant total 10 per cent of
~ 20% for effluent sampling experiment.
Indoor hydrant system should also be readily observed fire water tank, the tank's water level conditions
found enough time to add. Usually need to strengthen the pump motor maintenance and regular checks of
fire pumps of bottom valve and the outlet pipe valve and the valve is in normal state. Each fire pump shall
per 1 month for a running test to ensure that the water properly.
2. automatic sprinkler fire-fighting water supply system
maintenance management: automatic sprinkler fire-fighting water supply system as the building of one of the fixed fire extinguishing facilities,
must be full of water, fire and periodical checking system maturity level, so as to achieve a perfectly safe.
For automatic sprinkler fire-fighting water supply system of maintenance, should do the following
: doing a nozzle maintenance management. Should store the appropriate number of nozzle for replacement. Fire
spray when system is booted, no matter is the automatic opening of the nozzle or nozzles, unqualified
after fire should replace the corresponding type of sprinkler head. At the same time, the warehouse should have kept the number of spare sprinkler heads shall not
is less than the total number of installed nozzle 1 per cent of all types and different temperature scale number of sprinklers are
should not be less than 10 but not more than 50. To strengthen maintenance management, prevent nozzle rust. When
spray head installed in steam, chemically corrosive gases, moisture concentration of large environments or
nozzles and dissimilar metal contact, nozzle will rustErosion, at this point in time will replace corroded nozzle. Should
only preventing dust buildup in the nozzle, affect the sensitivity of the sprinkler head movements. Check in
nozzles on the heap using Cumulus dust brush out or blown clean. To prevent water distribution pipe and nozzle clogging. Since
distribution mains in easy to sand, debris and other debris, the pipeline passes water blocked,
when these odds and ends when the action is in the head, along with the flow into the nozzle and the nozzle clogging. Should prevent water distribution and
head dripping nozzle. Cause water distribution pipe and nozzle leak was mainly attributable to the pipeline rupture, frozen
sprinkler piping and mechanical damage or nozzle overheated and so on. Therefore, in the high area,
steam room, heating and prone to overheating of the place, to prevent accidental injection nozzles, paying special attention to the
often conducted through the inspection and maintenance.
Periodically checks the entire spray system, ensure the system's integrity. Should keep
observation: the adoption of protective measures for the part is all protection measures; the gate valve open and close the system state
meets the requirements, wet alarm valve, dry alarm valve, valve, preaction valve
of pressure gauges and pressure is displayed with the design requirements; fire water tank, water tanks of water level
whether you want to order, and to do so, each month on the fire pump to carry out a running test, a
operating time as no less than 5 minutes per week on fire pumps, air compressors, fire
electric equipment into line.
(5)
power check to check the automatic fire alarm system of an AC power source is as large
device power in together and cause fluctuations. When you find the automatic fire alarm system of power supply lines and other
lighting use, dynamic lines combined with the same loop, measures should be taken to separate settings, ensure that
fixed fire-alarm system separate circuit power supply. Check the automatic fire alarm system voltage
offset is in the allowable range, or the measures to be taken of the surge. Check the main power and standby power
between automatic switching is normal, you can cut off the power, check its can be converted to the standby power supply,
if the existing fault, the measures should be taken. Power check general each quarter to
standby power for 1-2 times the charge and discharge test, 1 – 3 main and standby power supply automatic switching test.
(6) ensure the coordinated control system
properly coordinated control system to protect the building security has a very important role in
therefore on room within the fire hydrant systems, automatic sprinkler systems, electric fire doors, fire shutter,
ventilation and air conditioning, smoke devices and electric fire damper control device actions to guarantee the functioning,
check checked if the linkage system action properly, signal will feedback to fire control rooms, if
no feedback on device failure, it shall promptly take measures to eliminate.
On halon, carbon dioxide, foam, dry powder, fixed fire-extinguishing system, you can
proposed by mold test.
You should also check whether mandatory fire control center elevator stopped on the first floor.
Fire accident in the test, whether the speaker when the broadcast is working,
should be able to switch to the fire radio channel.
On all fire and evacuation of led lights to test fire control devices can be connected, and whether the normal action.
Check all switch if the power switch, fire switch, smoke,
fire proof doors, fire shutter, changeover switches, alerts, transfer switch, emergency lighting
transfer switch, etc. is not the action.
Is found in the check fails, the staff should be processed in a timely manner to
guaranteed the entire system is in good condition.
(VII) establish strict management system and
system operating procedures developed strict management system and system procedures, for the relevant personnel have
performed, plus strong on part-time firefighters training, enhancing fire safety awareness, establish
post responsibility system, to ensure that 24 hours monitoring at any time someone on duty. At the same time, the clear responsibility to the people,
on the system of inspection and maintenance of the register for verification.
