Hi, I don't know who makes the 9500 keypad. I think the code may be remembered numerically, and then the user remembers it sub-consciously or by muscle memory. The segment spacing looked too tight to be representative of a clock face.
-
I am curious to know what it is because it is rare to see this sort of technology used in public.
-
It is Halifax.
-
The lock was at a bank in 2008. I didn't take a photograph because I didn't think that I would need one, and the staff may not have been comfortable with such action. It is not the one above. The face plate was white and the segments were keys that would be entered to form a code.

I have seen a reader that appears to be a square like plate with a circle of segments going around. The user inputs the code in this format. There are no numbers displayed. Do you know what type of device it would be ... any brands/models in question?
-
What if it is not?
-
Do owners of NSI installations get full control of the systems or are certain features like part sets locked off? A friend uses a system in a commercial premises, and they are required to unarm with RFID and arm with code. What kind of rules apply for both domestic and commercial installations?
-
Hi, If it is +15v, that means that the battery is being overcharged, though, right? I thought on the basis of faults that the spare core might have become unterminated.
-
Our system uses an external keypad. I do have a couple of other questions though. Whilst the panel was in the engineer programme, I had the lid off, which was fine, but when I unscrewed the bar, an alarm condition was triggered, which had to be reset. I connected what appeared to be a loose/spare core into a central junction block, which I think is the global tamper. I then removed it again, and the strobe light now doesn't seem to work. If you are curious why I conducted this action, it was due to the faults referenced earlier in the post, thinking that the loose core might be the problem.

Hi, What is 'the resistor issue'? The Lynteck Nexus 8 has a default routine of just disconnecting power (mains and battery), which has defaulted for having a low battery.
-
The system is unserviced in the house and we don't use it really anymore because people are usually in, with a dog. The battery itself is like from the 90's, and was only giving half of the power needed. There have been faults with the system before where it would suddenly activate and the code would default itself. It only happened once, and was like the day after I defaulted it.
-
It was a refuge smoke alarm at the roadside with the screw, dryline plug, and cut cables on it.
-
I hear these strange noises, and put my head out of the window and they sound like they are coming from the intruder bell. It sounds like a smoke alarm tone, but I have never heard this before. There is a possibility that it could be coming from the roadside or otherwise. I have entered the engineer's programme on The ADE Optima Plus 2, conducted a bell test, turned FCU off, and nothing has changed. There is no battery in the panel, and the bell battery is likely to have worn out (installed in 90's). https://youtu.be/cKWVqqEklCM

Does this means that the fuses have failed to do their job, or are they not protecting that part?
-
about 4.5v for battery itself, and around 14v on the charger wires. Battery is disconnected.
-
That is why I didn't want to change the battery, and did remove it several months ago.
-
I found that there was a metal bar at the top that holds the PCB, and as I was trying to remove it, I thought that if I did, the cables wouldn't reach and get pulled out. It also triggered a case tamper, despite being in engineer mode. I will consider taking it out of the housing at some point and seeing if there are any damaged components on the board. I did probe the two fuses and got negative readings.
-
I appreciate advice on here, but many posts appear to be sales pitches with "throw it away" type of answers. I like to prove that a product is fully deffective before anything gets disposed.
-
Should the battery affect anything else though, or is it purely for the event of a complete mains failure?
-
There was a case tamper full alarm condition (including bell) whilst I was moving the PCB. It was in engineer mode. I had to cancel it with the user code, and couldn't reset or re-enter engineer mode until the lid was closed, and then start again.
-
The battery is giving out about 4.5v, and the charger 14v (decimal something). I used a multimeter. I don't see how the system using LED instead of LCD can affect it's performance, as the modern equivalent is the Honeywell G4, and that is available in both options. The system belongs to the family, and we would like to see what/if the faults are, before any consideration is made about having a new panel. The battery is not connected. The system should work without a battery, as it is just for redundancy isn't it? We don't use the system much as the building is well occupied etc.
-
I will test both the battery and charger in a few. Could this cause any other faults though, such as the bell tamper?
-
The battery itself tested whilst not connected gave about that. It was fitted in the 1990's.
-
There is no way that misprogramming or similar could cause such results, is there?
