A fixed switch (such as S2309TP-EI-DC) can record alarms but not logs after a loop detection-enabled interface detects a loop. The configurations are as follows:
In V100R005 and V100R006, you can run the snmp-agent trap enable feature-name ldttrap command to enable the alarm function for loop detection. If snmp-agent trap enable has been configured globally, the alarm function has been enabled.
Loop detection and loopback detection have been available since V200R001. You can run the snmp-agent trap enable feature-name ldttrap command to enable the alarm function for loop detection and run the snmp-agent trap enable feature-name lbdt command to enable the alarm function for loopback detection.
You can run the display trapbuffer command to view alarms.

How to configure Ring Check of the MA5800?

The Ring Check feature enables the device to send the Ring Check packets periodically and monitors the Ring Check packets received on the user-side, cascade-side, and network-side to detect whether a loop occurs on the network of the carrier. If a loop occurs, the MA5800 deactivates the subscriber port on the loop and reports the corresponding alarm to the NMS. This ensures that the device runs in the normal state and that legal users are not affected.
Run the ring check enable command to enable the user-side ring network detection.
Run the ring check uplink detection enable command to enable the network-side ring network detection.
Run the ring check cascade detection enable command to enable the cascade-side ring network detection.

Hi there, my Motorola Hubble is pointing out of my window to my car and front door but it’s not sending me notifications of movement ie when postman put mail in letterbox ?

Change Cameras' Placement or Pointing Angle Security cameras with built-in PIR motion sensor, such as Arlo cameras could see cameras do detect motion but fail to record or capture movement. Or cameras can't detect or record motions through glass or window glass panel.
In such cases, avoid placing motion detection security cameras behind the glass window especially cameras with a PIR motion sensor; do place wireless motion sensor security cameras closer to a WiFi router or hotspot.
The object from afar is relatively easier to be miss out, so don't expect security cameras to pick up every movement within its field of view. Focusing on strategic areas for motion detection helps achieve maximal peace of mind as well as reducing unwanted false alarms.

Why does the gate open on its own during the day with nobody home?

There are several ways a gate will open. You need to check each of them but the most common issue we find when repairing gates is the exiting vehicle detection device is opening the gate.

There are two main types. The best type will be a loop embedded in the driveway. These normally open the gate by driving over them. A sensor in the operator sends an electrical wave through the loop. A vehicle affects this wave and the sensor detects it, flips a switch and opens the gate.

If the installer used standard PVC wire, and the driveway cracks to let water sit on the wires, they could change the wave occasionally and open the gate. Water can take days to soak through and remain around for days. So while you do not have rain or sprinklers going the day the gate opens, it could still be the cause.

The sensor inside the operator could also be going out. Usually, they have lights showing when they are active. If you have one, and the detection light is on, turn off the machine, disconnect and reconnect the sensor and see if the detection light comes back on.

Next check the loop wires. Physically, look at the wires wherever you can. Check the driveway for exposed wires. If you find them, call a pro to replace them. Once this is done, you need an ohmmeter. Plunge a screwdriver deep in the ground. Set the dial on the ohmmeter to measure how much resistance there is between one wire in the loop and the screwdriver in the ground. Make sure you are not touching the leads or wires with both hands since you will be measuring your bodies resistance and not the short between the ground and the wires you are looking for.

If you find anything but an open circuit, there is a problem with the loop wires and you will need to replace them. If you have a completely open circuit, then change the detector. Ideally, you have another detector for the safety loops and can switch them to see if the problem moves to the safety loops. If it does, replace the detector.

The second type of exit device is called an exit wand or exit probe.

These are overly sensitive and don't last as long as the loop detector. Your dogs collar can set it off as can a bicycle or even a workers steel-toed boots. Add to this, the propensity to fail, and if you have one of these, you have likely found the problem.

The fix for these is to pull the probe up, look for nicks or cuts in the wire and fix them, dig a deeper trench, cover the wire with PVC pipe to prevent more cuts and finally bury the wand itself at least six inches deep. By the way, if the probe cable runs next to other electrical lines, they can make the probe react too. I have heard this can be prevented by using copper pipe instead of PVC pipe.

Other causes could be a remote in someones purse or pocket going off as it bumps around, a switch used to open the gate shorting out, a call box getting signals and in general anything used to open the gate breaking down or being set off inadvertently.

Rarely, and I mean very rarely, a control board, the big circuit board controlling the gate motor itself, will go out and cause this sort of problem. Out of everything, this is the least likely.

Good luck.

Hello, I have found a Sansui DA-T550 music-system with AM/FM stereo tuner, integrated amplifier, cassette deck and turnable/gramophone (placed separated). It seems like the system is working OK. My...

Hi!

I have the same deck. Did it come with rammophone or are you using your own grammophone?
I have it with original grammophone and I don't need a remote control, I don't even have it. You just turn on your grammophone and it is automatic, just place the needle on record and it should switch and play automatically. That is if you have connected the wires right (two wires for sound, one for automation, all in the same area).

If you have separate grammophone, I am assuming you just need to place two wires into the separate phono channels and it should work. There is just no automatic detection, so you have to swithc to mono manually: There is a button on the right, beside Volume control "tape to CD" or something.

To play the tape, just simply push the play button on the bottom, should work, or you could try tape to cd button off and see if it detects automatically when tape is inserted.


Currently I have it taken apart and there is tape detection system apparent. Its quite automated reciever, which sucks, because all kinds of problems appear and it is difficult to fix.

On my Sansui, the tape player starts winding slowly when pressed play button. And the tape motor seems to be on always, even when the tape is not used, and the motor is really loud. --Need to find a solution to this problem. And I hate it switch to radio/FM every time the record stops. Plus the original grammophone doesn't work correctly, it is supposed to take off the needle when record reaches an end, but it just pushes the neelde to the holder... over the record..... "screeeeech".

Engine code p1309 P/S advice on repair

The definition of this code is:
P1309 Engine Misfire Detection Monitor not enabled

It's a problem with the detection circuitry, not a detection of a engine misfire condition. I found this quickly on the net:
Diagnostic Trouble Code (DTC) P1309 indicates Misfire Detection Monitor is not enabled.

Breakout box installed, PCM disconnected. Connect digital multimeter between PCM test pin 85 and test pins 51 or 103. Bump engine in short burst with the starter without starting engine for at least 10 engine revolutions. Answer this question: Does digital multimeter reading switch between low (less than 2.0 volts DC) and high (greater than 8.0 volts DC)?

If Yes, Verify correct installation by referring to the Powertrain/Engine Group in the Workshop Manual. If the CMP is installed properly, REPLACE PCM. RESTORE vehicle. RERUN Quick Test.

If no, REPLACE CMP sensor. RESTORE vehicle. COMPLETE Misfire Monitor Repair Verification Drive Cycle. RERUN Quick Test.

The CMP sensor is the Camshaft Position Sensor.

My alarm goes off randomly

Many alarms have a mercury tilt switch for motion detection, and if it is set too sensitively, a good gust of wind can set it off.
You need to adjust its sensitivity setting.
