【 Weak current College 】 automatic fire alarm system management and maintenance

Automatic fire alarm system is a State-of-the-art technical facilities, fire not only expensive, and the use of performance is strong, so the user upon installation, it is necessary to strengthen the management and maintenance of fire-fighting role to play in full. For automatic fire alarm system management and maintenance are made the following comments.
Automatic fire alarm system is a State-of-the-art technical facilities, fire not only expensive, and the use of performance is strong, so the user upon installation, it is necessary to strengthen the management and maintenance of fire-fighting role to play in full. For automatic fire alarm system management and maintenance are made the following comments.

(A) strengthen the automatic fire alarm system technology management of archival materials.

At present, some use 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, not only to provide information on the fire service, for the "system" and its management and maintenance are important reference value. Care must be taken:

In automatic fire alarm system installation has been completed, the user should be in the design, construction, installation of units in respect of the system of construction drawings and technical data and installation of technical records and system sections test records, reports, commissioning and acceptance report, etc, the establishment of technical files, safekeeping, for the query. At the same time, in the "system" in the opening run before should establish the appropriate procedures, on-duty staff duty, duty to record, display system in the building location plan or simulation, system running form, such as equipment maintenance 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, but you cannot apply by design, the construction sector, the timely replacement. If the room to the kitchen, the boiler house, boiling water, generator room when it should be changed to smoke-detector temperature sensor type detector. As far as determination of smoke-detector environment temperature of around 50 ° c in General, or they can fail; but fixed temperature detector action rated temperature should be higher than the ambient temperature 10 ℃-35 ℃.

To prevent outside interference or accidental damage. For detectors is not only to prevent smoke, dust and similar 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 rack for storing or equipment, partition, separated on the detector and manual alarm button.

For the second place, the decoration is necessary to pay attention to check the original detector and alarm buttons, and so on are intact, if available, the line. If the above issues must be repaired or replaced, otherwise the alarm beep will occur.

Note on the detector of cleaning and the care of spare parts. In order to keep it in good condition, properly, you should run the probe opened two years later, every three years all cleaning again.

(3) alarm device checks.

When the checks are carried out on a fire detector smoke with special tools for hands-on inspection. When fire detectors in after receiving a smoke alarm acknowledgement lights to indicate that the detector is working, at the same time to the alarm controller issued a fire signal. Also check whether there is a clock, no fire time records. Inspection, the person on duty should promptly the silencers, reset in case of long make the device component is damaged.

(4) power check

You can check the automatic fire alarm system of an AC power by and large equipment power together cause fluctuations. When you find the automatic fire alarm system of power supply lines and other use of lighting, power lines and the same loop, measures should be taken to separate settings, ensure that the automatic fire alarm system separate circuit power supply. Check the automatic fire alarm system voltage offset is in the allowed range, the measures to be taken of the surge. Check the main power and standby power supply automatic switching between normal, you can cut off the power, check its can be converted to the standby power supply, if there is failure, measures should be taken. Power check general each quarter to standby power supply for 1-2 times the charge and discharge test, 1 – 3 main and standby power supply automatic switching test.

(5) ensure the coordinated control system's normal operation.

Coordinated control system to protect the building security has a very important role on indoor hydrant systems, automatic sprinkler systems, electric fire doors, fire shutter, ventilation and air conditioning, smoke exhaust equipment and electric fire damper control device actions to guarantee the functioning properly, check 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 check through simulation 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, you 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 doors, fire shutter, changeover switches, alerts, transfer switch, emergency lighting switch, and so is the action.

For check in, staff should be processed in a timely manner to ensure that the entire system is in good condition.
