Early am had a large thunderclap above the house. Alarm box (intellisense ag8) sounder triggered in battery mode. No Strobes. The keypad for galaxy panel showed no alarm status. Only way to silence was to remove battery link from the sounder box and kill power and disconect battery at the panel. sounds like a new sounder box to me is this a common occurance.

It could still be the panel locked up, may be an idea to have someone come and check the alarm over for you.

Lightning is causing more severe problems than ever, it is not uncommon for a complete system to be wiped out - even if ancilliary equipment appears to work fine, lightning can cause damage to chips that only shows up months down the road.

tell me about it.....................

last time round i was mopping up cctv systems - casmeras, muxes etc for weeks

We are a North West based company give us a call and we will callout and repair it for you.

yeah your galaxy survived but the bell didnt, lesser panels would probably have keeled over too, but lighting is so powerfull you dont know how much damage it will do. Not common but lighting does indeed damage intruder alarms, cctv, routers, sky boxes tv.'s... etc etc

Thanks for the info, are some bell boxes more sensitive than others? my easy option is to replace like with like but if you know of any more robust options let me know

i think all bells(if struck by lightning)would'nt be that robust at all!!!!!!!!!!!!!!!!!!!!!

id go for a lightning proof decoy model lol.

Nothing can take lightning not even the ground

i would go for the decoy model as well...it will never give you a false alarm

imo if above 12 feet from ground best to avoid matal clad or metal shielded ones, as they atract more lightning hits pro-rata than mainly plastic sirens.

many systems damaged in storms are not as a result of a direct hit, but the induced high voltage's in cables or metal covers after a local strike, this is what fries the eletronics.

the direct hits are easier to diagnose, sniff for an ackrid smell, and look for the sight of a pile of ashes on the floor below, where once was the control panel on te wall.

My experience is that by far the majority of lightning problems come down the telephone line.
