Hi all im fozzy and have just found this site im looking for a bit of advice after taking a new roll in a company im from a maily fire back ground,

access and cctv, but this role involves alot of security systems in which ive worked on quite a few systems but installing not the fault finding side.

one of the things ive noticed is:-

im getting alot of false activaions from PA`s when i check them out none in several locations have been actived

any hints or tips would be good

fozzy

false alarms on a deliberate devices, very easy to work out

measure device form panel end, should be stable & quite close to the readings taken on commissioning check for short to other cores

if eol you may want to pair in panel & take measurement from button

terminations should be secure including any resistors used, also the button should not be loose on the surface its mounted on ect...

the internal of the device should not slopping around either

so as with most faults its one or more of device, panel, cable or terminations

Replace the user and try again...

^^ Most common false alarm cause sadly.
