lol,
its supports a single wireless expander, 8 zone + 8 keyfobs, reports, alarms tamper, low battery ect...
the digi works as speech dialler,
its not a bad product, but gardtec quirky with cheap looking rkp
if you do if for a living its easy enough
the fault with normally be, cable, device or controls
is their power at every keypad ?
no = check power is provided for the keypads at the controls / power supplies
then check wiring & the data line is terminated with 680omhn (or whatever) ect..
should the wiring prove okay, put each 1 keypad on data bus at the panel on short length of wire with 680omhn resistor (or whatever) to terminate the data , if every keypad don't work its probably the controls
if you can afford a dog & home / property big enough for 4 keypads, you be in position for the maintainer of your security system to pop along during the week & short it out for you ?
nowt, I used to do this & the other building opposite for the landlord.
The one is the pic is a 1st & 2nd floor HMO, Shop & the building on the corner is a Pizza shop
I'd priced to replace a Newlec with a Kentec panel + add 2 repeaters some years ago.. he told me how much he 'd been quoted & asked me to match it...
It was something laughable
The other premises has is similar, 2 shops + HMO. Haes controls which I rather liked.
cool, usual thing of cable, device or controls
if the cable is laid under the boards in a manner its trapped or damaged by a pipe, walking around on the floor above it may send the alarm batshit,
something drawing lots of current, eg too much stuff on small controls may send the alarm batshit
something odd is happening , check all the fuses are the correct rating eg-
some mong may have a 5amp fuse where a 1amp belongs & when it draws too much current it batshits the alarm & does not blown the fuse
with the tamper tied down gently press parts of the endstation pcb to see if it goes batshit
check both continuity of all the all cables & then take them apart & check there is no shorts on every pair ?
or change you mobile no. & find a new friend with a working alarm ?
default & reprogram,
if it does it again , replace controls after check the cables....
is this just a system just a single EWD, 1 keypad, 1 speaker & a handfull of pir ?
