Disabling a portion of an armed system

[Guest]

Is it possible (which panel?) to have a system where the alarm can be
activated, but through a wireless system, just the external passive (for
example) can be disabled allowing one o approach the front door where the
usual routine of typing in the code to disarm happens.

Thanks
Michael

You must live in an area were the local authorities haven't had enough of
the false alarm problem yet or they have had enough and are not responding
anymore.

Huh? Neither.

I just want to have the ability for my tennt who rents the cottage to
disable a portion of the externl security to gain access to the cottage,
without being able to do anything else....

I quess I should of asked if this is a monitored system. Monitored systems
with exterior protection are systems that will generate false alarms or
should I put it as "creating unnecessary dispatches" since the system is
doing what you intented it to do, by detecting someone approaching your
home. My only suggestion would be to put that particular device on a delay
in order to give the user time to disarm the system. Most panels will not
allow for customization, of any features, while in the armed postition.
Depending on the panel, some of the wireless keyfob devices have a mulitude
of programming options. There may be one with an exit feature giving you
time to exit (or enter) through a delay door. (two minutes lets say) Then
again, the same keyfob would probably have a disarm feature anyway. The
trick would be to have the range of the wireless greater than that of your
protection. Some of the more techy design guys on the NG may be able to
answer which products are available, if any. Sorry about throwing a curve on
the orginal post. I am just not a big fan of exterior protection on a
monitored system where the general public may have access i.e. paperboys,
mailman, delivery (FedEx, UPS), lawn service, neighbors pets, etc. Let us
know if you come up with something.

Good luck

Monitored or not... what happens when the alarm goes off? Sirens only?
Believe it or not, someone hearing it may call the cops, you don't want to
do that. If it's a cottage, the thing must be going off all the time what
with critters and all. If all the "alarm" does is notify you by phone or
pager, then fine, false dispatches are unlikely but Bob is right, we need
more details... what happens when the alarm is tripped?

 

[Guest]

hehehe... I see some more explanation is required... this is good ol'
Johannesburg South Africa... where petty theft is a way of life, bank heists
far too common, and general law and order a largish problem... hopefully it
is improving though.

My home, as are all homes around me, and in all the suburbs around me, is
totally enclosed. I happen to have a steel palisade fence, and many others
have walls, always situated where the pavement (sidewalk?) ends and my
property begins. Almost everyone has an electric fence on top of their wall.

Insurance companies demand that their clients have (a) good home security
(b) and alarm system and (c) are linked to an armed response. I happen to be
linked to ADT.

False dispatches do happen of course, though it will never be the police...
always the security company (ADT, Chubb, Stallion, etc). The police are
never part of the loop...more important things to do I suppose.

So... back to the question...

My tenant has a remote that will open my (automatic) gate. before he does
so, I would like him to be able to disable a portion of the alarm that
affects directly him, only. like the beam across the driveway.

Does that help?
Thanks
Michael

 

[Guest]

Oh yes... the tenant has a cottage which is a totally separate building on
the same property, set to one side and behind the main house.

Thanks

Great. I have a locally produced gate motor called a "Centurion D5" which
certainly has the capabilities to be integrated with... that part doesn't
worry me. For he alarm system side, I am considering purchasing a DSC 832,
which I believe does have the partitioning features.

The only part I don't quite understand is ... if I have an 832 panel all set
up right, then what would happen is that the tenant would press a wireless
control, and that would open the gate, which would simultaneously "tell" the
panel to disarm a specific partition. The panel would then re-arm the
partition 5 minutes (or whatever) later.

Is this right?

Thanks
Michael

Marvellous.

I'm happy to consider other makes.... what makes you say that Napco
provides a better way than DSC?

Thanks
Michael

 

[Mark Leuck]

1. He once installed them
2. Its about the only panel he knows
3. He wants you to buy one from him as well as the octal relay (the biggest
reason)

5. Every panel out there can do relays, Napco doesn't do it any better or
worse than the others
6. I'd stick with DSC myself if given the choice, easier to program

 

[Mark Leuck]

For one thing, Napco is infinitely more flexible than DSC. Each zone has
more than 60 individually selectable features -- none of which are "global."
That is, you can program any zone (sensor loop) completely differently from
every other zone. With DSC there are far fewer options. Even the most
basic selection, EOL resistor choice, is global with DSC. That which
applies to one zone necessarily applies to the rest.

There have been numerous reports of failed DSC power supplies. I don't mean
the plug-in transformer; the on-board circuitry fails. Frankly, problems
and returns seem to have increased since Tyco bought them out and one
wonders if there's a correlation there.

The power supply problem started long before the Tyco buyout

Napco's RB-3008 octal relay board is also more configurable than the 4-relay
add-on boards from DSC. I've used them to completely control both the alarm
and peripheral systems based on multiple schedules and event detection. The
Napco software allows an end user to assign user codes and then specify
during what times of which days the codes can be used and on which
partitions they will function.

So will Ademco and ITI will over the Internet

True, but I have noticed a higher incidence of problem DSC boards lately. I
just had one last week. I was glad to have a spare with me since I was 2
hours from the nearest supply house. I think RHC might be right about the QC
issues.

Not that I'm ready to jump ship just yet, but I have started looking at
other controls. I received my first Caddx NX8E today, and I'll play with it
this weekend. One thing I like right off is the heavier can, and the 2 amp
power supply.

I'm trying out the NX8E, 148 LCD keypad, 8 point wireless receiver, and 4
different door/window transmitters. The little transmitters look good.

I'm not saying the problem stopped with Tyco just that it started before the
buyout.

The ITI transmitters are excellent, I suggest avoiding the SAW sensors and
go for the Crystal for longer battery life, sensor tampers and 2 reed
switches and external switch terminals.

I still can't get the hang of programming Caddx wireless but I don't get
many with it, the vast majority of Caddx installs are hardwired. I haven't
heard of any power problems with Caddx yet, in fact I haven't heard of any
problems period with them and many people left DSC for the brand for THAT
reason

 

[Frank Olson]

I suspect you're going to be pleased. Caddx has improved quite a bit since
the older style "Ranger" panels. IMO their wireless is significantly better
made than DSC's.

Speaking of wireless, there's another issue with DSC that rankles me and
quite a few other dealers. As a cost saving measure (according to a DSC
insider) they decided to drop support for tens of thousands of existing 900
mHz wireless systems. DSC dropped the 900 mHz in favor of cheaper to
produce 433 mHz. That's understandable enough, but they stopped providing
new 900 mHz parts entirely while many existing installations were only a
year or two old. This effectively obsolesced the existing systems of
thousands of dealers all over the US and Canada.

Uh-huh... and you *still* offer their products for sale on your website...
along with Ademco contacts (which you neither use or recommend)... Most dealers
(who feel as you do) drop the offending product line...

Tsk...
