I have a Yale HSA6200 wireless alarm. It seems to work fine but the control panel is showing weird symbols in place of the date etc. I can reset the alarm but then the symbols come back (not always the same ones). How can I get rid of these?
 
I think the liquid crystal display is probably degraded with age, or possibly damp. I don't think you will be able to repair it. I presume you are keeping it well charged. The batteries also degrade with age, and you can buy replacements.

This often happens with old devices such as calculators and cordless phones. Usually when they are old enough to be sent to recycling.

That Yale range is perfectly adequate for most homes, I used to use them, I preferred the HSA6400 which could be plugged into a phone socket and call you in the event of an alert. It is a direct swap for the 6200 panel. If you have a house crammed with gold jewellery or other portable valuables, a professional who knows how can defeat them, but the average teen crack head has neither the knowledge nor the tools.

If you are happy with it, keep an eye on Ebay. Used ones crop up quite often. You can get the instructions online if yours are lost. You can fit an extra siren, for example indoors upstairs where you will hear it, or at the back of the house, there is no limit to the number of sirens you can have, or extra sensors if you find a cheap seller. Alkaline batteries last a couple of years and are cheap. The later, modern models are not compatible.

If you ever need to install these, I find it a great advantage to lay out all the components on a table, with the siren wrapped in a blanket, to learn them in and test them. This is much easier than trying to fiddle with them once they have been screwed into place and you need to climb ladders.
 
Thank you for your response.
It is connected to the mains so not batteries. It is also connected to the phone and will ring me up. Its just that I get funny symbols instead of letters (such as * ! %").
 
It has a standby battery inside, accessible through a hatch on the back. Coloured green. I suppose they last about ten years. Keeps the system running in a power cut or if charger is unplugged.

If yours has the telephone connector I think it is a 6400, not a 6200.

I don't know how old yours is.
 
Thanks again.
It is definitely a 6200.
I am not sure about the hatch on the back? I unscrewed the whole of the back and inside there looks like what are 6 aaa batteries sealed in green plastic and attached to the alarm by red and black wires. I did not try to access these as they are clamped in by a metal strip held in by two screws. Should I be looking for a small cell battery?
 
No, the green pack is rechargeable batteries, with a connection lead attached, as a standby in case of loss of mains power.

But if, as I think, the fault is in the LCD, it is probably not fixable. Tbe display itself will not stop the system working, but makes it awkward to use. I was wondering if low battery voltage might be the trouble, but provably not.

I occasionally had one run down after a power cut. Can't remember, they might have had a 20 hour standby, so would go flat o or a weekend. If one ran down quickly, I fitted new batteries. I think the ones I got were Tamya or something like that, for toy cars.

It's a long time ago, and the Yale systems have since been revised. Used to be about £180 and very popular. I thought the phone-dial out was a very good feature.

Do you know how old yours is?
 
The Siren batteries are "D" size and last years. Maybe 5? I write the date on them as a guide for next time.

Just as well, because many people fit them where you need a ladder.

I prefer accessible from an upstairs window.

I'd have thought yours is the old type.
 
I see I was using them around 2009-2015.

And I made a note the siren batteries lasted around 3 years.
 
As a last resort, you can do a "factory reset" on it. This will lose all the user data like PIN codes, telrphkne numbers, and learned-in sensors. So I would only try it if I was on the verge of binning the control panel. Everything else can be used with a new control panel, provided it is of the same generation.
