Anyone who might have an unwanted/broken/leftover alarm siren from a 355 or 550. I would like to have a shot at fixing it I will happly pay postage and document everything I did and post here with pics. Thanks, Dave Numbers on it are : 980731 F005U00088 ( hard to read, a guess) 177148 Ver. 1.0 I believe a 360 siren will not work on a 355 so I would have no way to test a 360 siren.
I believe I may have located a source for the batteries in the USA, however I need a dead siren to work on as the PC board in mine is toasted. Will know more in a day or two.
