Does the fire controller not have the alarm function if the main power supply fails?

The gas fire extinguishing controller should be equipped with a fault indicator, which should be lit when there is a fault. When the following faults occur, the gas fire extinguishing controller should send out the corresponding fault sound and light signal within 100s, so the fault sound signal should be able to be eliminated manually, and when there is a fault signal input, it should be able to start again; The fault optical signal should be maintained until troubleshooting. The connection line between the gas extinguishing controller and the audible and visual alarm is broken, short-circuited, and functionally affected grounding.

The connection between the gas extinguishing controller and the driving components, on-site start and stop buttons (buttons), etc., is broken, short-circuited, and affects the grounding of the function. The connection between the charger charged by the backup power supply and the backup power supply is disconnected or short-circuited. The connection line between the standby power supply and its load is broken or short-circuited.

The main power supply is undervoltage. Where the fault of the item ) should indicate the location of the fault of the item ) the fault should indicate the type. The fault signal of the gas extinguishing controller is after troubleshooting.

2. There may be a problem with the connection between the main power and the fire control cabinet, resulting in a power outage Usually because the fire fighting equipment needs a double circuit power supply to ensure that there is electricity available in the event of a fire, the fire control cabinet is divided into main power and standby power, and the main power is displayed after the main power is stopped, and it will be immediately switched to the standby power (the standby power is usually a battery, or the second power supply). When the main power failure is displayed, it is necessary to find out the cause as soon as possible, check the equipment, and restore the power supply. The fire-fighting electrical equipment is double-circuit power supply.

2. The fire control cabinet you refer to should be the fire alarm linkage controller. 3. The fire alarm linkage controller adopts mains power supply and the controller's own floating battery pack for power supply. 4. Now the controller reports the main power failure problem as follows:

There is a shortage of electricity in the mains. The main electric fuse of the power supply panel of the controller power supply is blown out. The controller power supply is partially faulty.

1. Yes, because there is a backup power supply that can be taken to work normally.

2. The function of the fire controller will not be affected when the backup power supply is provided.

The main power supply is faulty, is there still power in the circuit? How can you call the police if you don't have electricity?

Summary. Hello, the following is a little sister to solve your doubts for you, I hope it can help you.

Dear, the reasons for the failure of the fire alarm controller are: 1. The backup battery is damaged and cannot be charged. 2. The charging circuit of the power panel of the alarm is damaged and cannot be charged, resulting in the battery voltage being too low and reporting a fault.

3. There should be a fuse when the battery is connected to the power panel, check it to see if the fuse is blown out. (Look at how many years the alarm has been running, if it is long, the battery damage surface is large).

I really hope I can help you, and I wish you happiness every day!

The fire alarm controller has a backup power failure.

Where is the battery ready? How to change?

Kiss, 1The first method: the battery is directly at the bottom of the alarm, just like changing the battery of the remote control, there is a slide cover at the bottom like a side push to open, and then the battery poles are OK.

2.The second method: Twist the bottom cover clockwise (think of screwing a soda bottle) until it reaches a certain position and feels like it is stuck in a certain slot, and then pull it down to remove it.

Battery failure is a problem and how to solve it.

Only the battery can be replaced.

1. Common faults of fire detectors (1) Fault phenomenon: the fire alarm controller sends out a fault alarm, the fault indicator light is on, and the printer prints the fault type, time, and location of the detector. (2) Cause of failure:

The positive and negative poles of the alarm bus on the base terminal are reversed; The detector and the base fall off and have poor contact; Poor contact between the alarm bus and the base; Short circuit caused by open circuit of alarm bus or poor grounding performance; damage to the detector itself; Detector interface board failure; The device type in the host is incorrect. Common inducing causes: water seepage, decoration breakdown pipeline, loss, loosening or oxidation of the line wiring, type error in the main engine, etc.

3) Elimination method: re-calibrate the positive and negative poles of the bus and connect them; Re-tighten the detector or increase the contact area between the base and the detector circlip; Re-crimp the bus so that it is in good contact with the base; Faulty bus locations are identified and replaced; Replace the detector; repair or replacement of interface boards; Correct the type of device in the host. 2. Common faults of main power supply (1) Fault phenomenon:

The fire alarm controller sends out a fault alarm, the main power failure light is on, and the printer prints the main power failure and time. (2) Cause of failure: mains power outage; Poor contact of the power cord; The main electric fuse wire is fused;

Summary. Hello, when the main power of the fire linkage controller fails, the alarm sound is issued in the standby working state to eliminate the method: 1. The general fault of the linkage fire alarm controller probably includes the main and standby power failure and the bus fault.

When a fault occurs, you can press the "Silence" button to terminate the fault alarm sound. 2. If the main power is power-off, the standby power supply is used, and the standby power in the full state can maintain the controller to work for more than 8 hours until the standby power is automatically protected; After the automatic protection of standby power, in order to remind the user that the fire alarm system has been turned off, the controller will prompt the fault sound for 1 hour (the requirement of GB4717-2005); After using the over-backup power supply, you need to restore the main power supply as soon as possible and charge the battery for 48 hours to prevent the battery from being damaged. 3. If the system fails, it should be repaired in time, and if it needs to be shut down, it should be recorded in detail.

4. If the on-site equipment fails, it should be repaired in time, and if the fault cannot be eliminated in time due to special reasons, the equipment shielding function provided by the system should be used to temporarily shield the equipment from the system, and the equipment should be restored by using the unshielding function after troubleshooting.

Hello, when the main power of the fire linkage controller fails, the alarm sound is emitted in the standby working state to eliminate the method: 1. The general fault of the linkage fire alarm controller probably has the main fierce withering power backup fault and bus fault. When a fault occurs, you can press the "Silence" button to terminate the fault alarm sound.

2. If the main power is off, the standby power supply is used, and the standby power branch can maintain the controller working for more than 8 hours until the standby power is automatically protected; After the automatic protection of standby power, in order to remind the user that the fire alarm system has been turned off, the controller will prompt the fault sound for 1 hour (the requirement of GB4717-2005); After using the over-backup power supply, you need to restore the main power supply as soon as possible and charge the battery for 48 hours to prevent the battery from being damaged. 3.

Hello alarm sound has been wondering what is the reason.

Have you checked all the things you sent?

Dear, hello, I am glad to answer for you the fire linkage controller when the main power failure in the standby working state to send out an alarm sound so that elimination, if the main power failure, the use of standby power supply, in a full state of standby power can maintain the controller work for more than 8 hours, until the standby power is automatically protected; After the automatic protection of the backup power, in order to remind the user that the fire alarm system has been turned off, 1The fire alarm keeps ringing, usually if there is a fire, then we can eliminate the fire. If it is a false positive, then we can press and hold the reset key of the controller host.

2.If the host of the alarm controller keeps ringing, then we need to check whether the prompt message is faulty or really fire. When there is a failure, it is necessary to solve the fault, such as the problem of the line out of the wheel, and the equipment is damaged.

3.If it's a false positive, resetting it will do.
