HOME and car owners were today urged to have security alarms checked regularly after research showed one in three people ignored them if they went off accidentally.
A survey of 1,000 people revealed that many assumed someone else would respond to an alarm, or they didn't want to appear "nosey".
Police also no longer respond to audible alarms.
But officers insist that well-maintained alarm systems are a massive deterrent to criminals.
Pc Chris Green, Huddersfield crime prevention officer, said that 97% of house burglaries in the town were at properties not protected by alarms.
But he admitted: "Complacency is rife when an alarm goes off."
West Yorkshire has 48,000 alarms linked to monitoring stations, which can check if calls are genuine, but tens of thousands more audible alarms, which are the cause of many false alerts.
Det Chief Supt Andy Rennison, of West Yorkshire Police's Crime Division, said: "The alarm response system we have is graded.
"Police will respond immediately to intruder alarms if the alarm system complies with national standards.
" This means the alarm system is able to check itself to see if there is a genuine intruder or if it's a false alarm.
"Obviously we will attend if it is genuine - unless a number of false calls are received, in which case we will reduce our level of response.
"We would encourage people to use a reputable company to install their alarms and make sure they use them when they go out."
In today's survey, two out of three of those polled by finance firm Zurich said they often had their sleep disturbed by alarms, with one in six saying it affected their work.
