some item went tits on control 4 system
the dealer could have the item fixed for 4k, (but you only get 6 months warranty on a repair)
or a new item for 7.5k
when powered off it lost its config, (he'd never bother to look if their was coin battery on the pcb)
the proper monitoring of the alarm dropped by the wayside, I assume a few hundred quid was too dear
I got pissed of with Lenovo thinkpad's, last 2 broke hinges
I have a toughbook tablet thing but prefer a laptop
Work buys a laptop, it gets used at home for year or so, then goes to work when it gets marked then broken, meh.
There already a replacement machine waiting in the wings...
rip it out & put a decent lighting controller it, (but nobodys make anything to compete with it ?)
take the cover off & walk test it (they go opaque with age
swap sensor around to see it the fault follows
work the pots back & forth to see if the lux sense are at a working level
swap a sensor with a new one
fault finding is 2 man job after hours, it cheap to put the lights on timer
the recommenced minimum height is 3m ?
having to stand on a leaded bay was not uncommon
however-
working on this can't ready be done safety off a ladder?
an unsed TS700 with mains on the pcb, vintage....
