Alarm system - too clever by half

[fred]

I've just installed a clever alarm with 2 stage shock protection on the main door (it's a flat). A whack on the door sets off the sounder for a few seconds and giving it a kick sets off the main alarm, or that's what I had intended.

To ice the cake there's a 120dB sounder by the door to make sure a would be intruder gets the message, it's the sort that modulates, creating a rapid whok - whok - whok sound that makes your head feel like it is being whok

- whok - whoked with a baseball bat.

Unfortunately it's so loud that the shock sensor thinks WW3 has been declared and it causes the alarm to latch up and sound continuously.

After a while, I laughed. Stage 1 shock protection is disabled until I sort out my workaround :-)

A friend of mine who used to live in an upper floor flat in Birmingham decided he wanted to fit a very loud burglar alarm.

He managed to track down the company that produces nuclear melt down warning sounders for nuclear power stations.

He installed this sounder in his flat.

I've never seen it in action, but he said that the sound was so loud that you wouldn't venture any further than the front door.

I like it, just my kind of philosophy :-)

Allegedly some spoilsport has legislated limits on the output level of sounders but I'm doing my best to find the ones that have slipped by the limit.

Given the way most go off through faults etc rather than break ins, it's likely you will be the one to have your hearing damaged...
