Re: Comfort installation problems...

["Andrew Roberts" <andrew@xxxxxxx>]

Dear Paul,
All panels are verified as operational following assembly and then shipped
from us in Chester,
keypads are not tested in the UK, so there is scope for a possible faulty
keypad.

It is very possible to introduce many problems and even damage a PCB upon
installation,
so an inflicted hardware fault can't be ruled out.  It is essential to
strip
the installation down into logical blocks.

To verify that the panel is still ok now,  you must detach it from all low
voltage wiring that could still be introducing a fault
eg. zones, outputs, bellbox and phones but keep the keypad connected and
doorphone and ringer. The terminals all unplug, so a screwdriver is not
required. Make sure each block is labelled with it's zone/output numbers
before you do this.

1. Power it down from mains and battery.

2. Make sure all the zones are in the Non-EOL position with the jumper
towards the terminals on each zone.

3. Any 24 hour zones may need links in them and so does the bellbox Tamper
Return and 0v at the bottom of the PCB(link in the   two right hand
terminals).

4. Check data polarity for the RS485 comms, do not connect the PC interface
(this can disable the RS485 and kill the keypads)
If you get Communications Failure 65 you may have the RS485 polarity the
wrong way round or Comms Failure 49 is the Doorphone?

5. Power Up the panel and attach the Lead Acid Battery. You should hear
'Security Off' from the keypad if wired correctly.
Test the keypad works as it should, enter *code#, check the menus can be
navigated. You may get a 'phone trouble' reported depending on how the
system is programmed with Locations 40 and 7.

6. If it passes this test, then the house wiring is at fault, if it doesn't
pass, then the PCB is damaged and will need replacement.

7. If ok, wire the Analogue port of the highway(check your handbook for the
correct terminals, if you have an RJ45 socket, it is pins 2 and 5 which
correllates with the two outer cores of a flat 4-core cable), direct to
Comforts TEL-IN terminals using a flying loose cable(Do not use the house
telephone cables in case they have a fault).

8.  Now wire the TEL-OUT on Comfort to a loose 'tel master socket' using a
short lead so you can attach a local phone to the system(do not use a DECT,
this introduces more 'unknowns' into the equation). Digital Analogue ports
can have a lower ring voltage and may not drive as many phone ringers(REN).

9. Measure the TEL-IN terminals on Comfort to check there is 49V DC coming
into Comfort.

10. Reset the system again, when you hear 'Security Off' again pick-up the
local phone and press STAR within 4 secs followed by 1234 #. You should
hear
the menus again.

Hopefully you will get this far, and if so, it points to wiring related
problems, which will involve adding each circuit gradually to the system
verifying at each stage that the keypad and operations are ok. Usually
adopting this approach, identifies the problem circuit as soon as it is
added to the system making it very simple to identify.

I would always recommend, setting-up a Comfort system on a bench BEFORE
actual installation, that way you can verify to yourself which elements
operate correctly and which do not. It's even easy to introduce faults in
programming, or setting a keypad jumper wrongly. Then when you start to
install, you can logically fault find installation errors because you have
the knowledge that if it worked fine on the bench then the problem is to be
found in the actual installation rather than the hardware which helps you
from following 'red herrings' or wrongly suspecting hardware which is may
be
ok.
