Hi guys, welcome everyone! Maybe you'll have any idea?

 

Risco Lightsys 2, no issues over last 5 years. I assume the battery just died (due to its age) and this is what happened then:

 

1. Power outage in my house

2. Alarm can't boot - it turns on for 0.5sec and resets again and again

3. I disconnected all the sensors - it boots

4. Connected the sensors again - still up and running

5. I replaced the battery, just in case

6. Another power outage

7. Alarm is not booting anymore:

• If I disconnect the sensors - it's booting for up to 0.5 sec and resets
• If I disconnect the sensors and battery - it's booting slightly longer (maybe 2 sec) and resets again

 

I managed to boot it once and it showed an "AC failure".

 

It seems that the motherboard is broken - do you have any idea what else could I check before I'll start looking for a new one?

 

Thanks!

Do you have a multi meter? what happens if you boot on battery only?

if it's all wired sensors.....

 

throw the controls away & buy something better

 

if you have various radio sensors & radio bells...

 

see above & replace them too

 

 

I haven't got much patience with Risco stuff, especially the Lightsys, they do odd things.

Really you would need to pull all field wiring and just wire the keypad on 1m of cable to prove the panel.

As 6 pull everything and tin a local keypad. If that fails then get something better
