Guest Peter MA Posted June 12, 2005 Posted June 12, 2005 Hello everyone I'm a new member, and I've been searching the various posts for a similar problem to mine. I've been very impressed by the wealth of knowledge you guys have. I haven't been able to find one thats exactly the same as my prob (apologies if someone's already answered the same problem.) I've got an Optima XM alarm (with 3 zones). The key pad was dead when we moved in 18 months ago and we called out an engineer who sorted the problem in minutes. He took the front panel off, fiddled about and the alarm started working again. There was no need for new battery or anything (batt says Nov 2001 on it). But the other week I turned the mains off several times in one evening, once for about 2 hrs. After I'd turned it back on, the key pad was no longer working. We had no bleeps or noises from the alarm when the mains was turned off or back on. Zones 1-3 are now lit red, attack is lit red, and day and power are on. Key pad doesn't respond at all. I've taken off the front panel (hoping it might trip the alarm into life) but nothing happens. I've also turned the mains on and off again but no change. I've had the mains on and off in the last 18 months and the probs happened once before and i called out an engineer that time. he fixed it in minutes (i think, in the same way as he did when we moved in). no need for change of battery or any parts replaced. Apart from this prob, the alarms worked perfectly for the last 18 months (we use it 3 times a day). Is there an easy answer to my probs which might save me another call out. I'm likely to have the mains on and off for the next few months as i'm working on the house - can't afford an engineer call out every other day!! Thanks a lot.
Adi Posted June 12, 2005 Posted June 12, 2005 Check the fuses and fit a new battery. I really can't be ar**** with it anymore.
morph Posted June 12, 2005 Posted June 12, 2005 You also need to check the battery charging circuit to ensure that it has not damaged the main circuit board, do this visually and also check the circuit with a multimeter. ***Switch the mains of before touching anything within the control panel as there is 240volts in there***
bellman Posted June 12, 2005 Posted June 12, 2005 Check the fuses and fit a new battery. 56728[/snapback] Quoted for agreement. Also check to make sure that you have at least 13 volts coming out of the battery leads as duff batteries typicaly fry the charging cct on these panels.

Nova-Security Posted June 12, 2005 Posted June 12, 2005 SOunds like it should have had a new battery when it was checked ! www.nova-security.co.uk www.nsiapproved.co.uk No PMs please unless i know you or you are using this board with your proper name.
Guest Peter MA Posted June 12, 2005 Posted June 12, 2005 Thanks a lot for your prompt responses. I'll try the above and let you know if i'm still befuzzled! Thanks again. Regards Pete
ccchicane Posted July 27, 2005 Posted July 27, 2005 You should check visually behind the keypad as the charging circuit usually burns a resistor behind here...Quite obvious by the naked eye from the back of the circuit board....hope this helps cc
Guest hudengineer Posted July 31, 2005 Posted July 31, 2005 Hi all, I've only just discovered this very relevant forum because our Optima XM has just packed up. An aroma reminiscent of TCP has greeted us in our hallway over the last week or so, and now seems to have been the warning sign that battery replacement was long overdue. Perhaps I could have read warning signs from the occasional alarm activation after one or two power interrupts in the last year or so, on an otherwise reliable unit. I'm embarrassed to say the battery would have been 14 years old by Xmas, but impressed that the Yuasa NP2.6-12 served for so long. Symptoms were: no response to keypad, no PIR LEDs blinking, only the control panel power LED glowing. Upon opening the control panel the bell box alarm went off (demonstrating that the bell box battery is still fit; how many years do they generally last?) and continued for what seemed like half an hour without power applied before I organised a ladder and intervened... As described by others above, I could see a 'stressed' looking resistor (component Id 17) behind the keypad. With power and battery disconnected, I checked the resistance of it (48 ohms), but found that the two short copper tracks that connect to the upper end of the resistor on the reverse of the board had disintegrated and were no longer making contact. I engineered a repair with a bit of stiff wire used as a substitute for the damaged tracks, and with the battery disconnected I reapplied power and the alarm system bleeped into life. With a new battery, and one more trip up the ladder, I hope to have a working system again soon. Andy
Service Engineer Posted July 31, 2005 Posted July 31, 2005 Well done mate, just check the battery charging voltage at the battery leads before attempting to connect your new battery. ........................................................ Dave Partridge (Romec Service Engineer)
JB_ Posted July 31, 2005 Posted July 31, 2005 An aroma reminiscent of TCP has greeted us in our hallway over the last week or so,62960[/snapback] A smell I guess we're all familiar with at a guess. Number of control panels blown up so far in 'career' = 3
