NX-148E Keypad

New member here......but looks like very knowledgeable people are members,with good answers from what I have seen.
I have a wireless sensor that a friend helped me replace in the fall of 2018. This past week there was a message on the keypad that that zone was lost. I took the cover off the sensor to find that the batteries were corroded.....they were Duracell and had come with the unit when I purchased it, so not sure why they would have leaked when they were in use for less than a year. I replaced the batteries and for 1 day all seemed well......now I am getting a message say LowBatt on that zone. I have changed the batteries 3 times now and still the message returns......and the keypad beeps until the code is entered, sometimes in the middle of the night.
Does that message have to be cleared? Does the system not automatically sense that the batteries were replaced?

If I cannot resolve this issue, is there a way to silence the keypad, at least until my friend gets back and can help me?

If it's the long, narrow transmitter that uses conventional batteries, there is a test button under the cover to press to get the panel to register the battery swap.

If there was corrosion, you may have to clean the terminals. An old style ink eraser works well, or rubbing alcohol and a cotton swap.

Thank you! It is the long narrow unit that uses 2 AAA batteries. I did not think about pressing that button to register the battery swap.
According to my supplier those OEM Duracell batteries that came with it should not have leaked after being installed less than a year ago.....they suspect corrosion may have affected PCB.

The problem with batteries, is that people often don't check how long that they have been sitting on the shelf. Some seller are better about stock rotation than others.

If the transmitter is damaged, it's generally not too difficult to replace with a new one; _if_ you have the installer code.

What _model_ is the system you NX-148 keypad is attached to?

The only other question you need to answer, is what model is your wireless receiver?

There were 3 versions The NX-4x8E models, the NX-548E; and the NX-148E-RF. Each has slightly different programming instructions.

If you have to replace the transmitter, I suggest the NX-650N model instead of the NX-450 that you currently have. Much longer battery life from the lithium battery, and it's more compact.

I think receiver is an NX-548E.....pic attached.
I also know the sensor is in partition 2, location 17.
Something I don’t understand is segments mentioned in programming.

That's a NX-408e, 416e, or 448e. The type of antenna, and the direction the LEDs point is kind of the give away...
