Connecting an alarm system to the IP Office 1

[jimbo1007]

A customer currently has an alarm which is connected up to an analogue line. The analogue line is being decommissioned and they have asked me to connect the alarm to the phone system so that if an intruder breaks in a call is made through the phone system rather than the analogue line.

I was thinking if I disconnect the two wire analogue cable going into the analogue line and place these wires into points 2 and 5 in a cat5 plug then place this into one of the analogue ports on the bri combo card, will this work?

Does anyone have any experience of doing this? Is there any configuration that needs to be done on the phone system?

Thanks in advance,

With the caveat that its not a good practice to run an alarm through a phone system unless it is on a UPS - it should work fine. I've done it several times temporarily. You will have to set up a hotline on that analogue extension so it can grab a line directly and the alarm people may not like it if there is no way to DID into that extension.

I think analogue lines for alarms should be actively discouraged now. GSM diallers tend to be more reliable as they can poll regularly as a heartbeat so you know everything is still alive.

Thanks ics, I did mention the GSM diallers but they wanted to save money.

Please could you break down how you would set this up as a hotline. This is a first for me so if you could break it down into a very simple process that would be great.

Thanks in advance,

Its ok...just had a brainwave. Using the shortcodes ?D

 

[jimbo1007]

However, can I just confirm that when *d is entered in the short codes for this extension the system will automatically dial the chosen number. It was my understanding that this only worked when there was an actual extension used and not just a dummy extension?

Just setup the analogue extension port as if you connect a phone to it and in the user shortcode list of the the user add a shortcode ?D/line access code/dial/Line ID = 0
When the alarmsystem wants to dial a number it will get a line and it can dial any number it needs.
As a alternative you can monitor to see what number it dials and add that to the users shortcode list :
12345678/<line access code>12345678/Dial Emergency/Line ID

Don't do it. That's it.

As per hold music
DONT!
connecting an alarm system through any equipment (PBX of GSM dialer) is a total No-No.

IPGuru, a GSM dialer is a prerequisite as backup these days.
But it must have a dedicated isdn line.

BAZINGA!

I'm not insane, my mother had me tested!

Like previously stated, no. If they insist, make them sign a disclaimer.

I don't see the problem.
The insurance company will force them to have a proper connection but if it is not part of a insurance contract the customer can do what he think that suits him.
It might as well be a analog port from a PBX, it is not what I would advice but it is the customers risk, not mine. The one who pays the bill decides. period.

Not sure in which part of the world you are but I also discourage the hookup of an alarm (or worse Elevator) line to the phone system.
Alarm systems are connected before anything else on that line and will take over even if the phone line is busy. If your system gets as many calls as your system has and someone intrudes your alarm system will not be able to dial out. Someone runs into the building (let's assume that there is a lot of money to get and the burglars are actually smart) they have 30 seconds (or whatever your entry delay is) to get to the phone system and pull the power plug.

Not a lot of time but enough if you know the locale or cut the power outside and wait 2 hours until the UPS dies.
As an analog backup for a digital alarm line ok, they can also upgrade their alarm system to get monitored via the Internet which they already have and which is also supervised but if they are too cheap to pay for a phone line that they can also use for fax, etc, then they will probably not pay for a new alarm system.
Get them to sign a waiver and be happy, it is at the end their problem and as long as you cover your behind YOU should be fine.

In my country we get this situation a lot. Usually the analogue line goes through the Alarm system before entering the PABX. This way if the Alarm is triggered ti takes over the line and has a direct connection.

 

[jimbo1007]

Thanks for all the responses here previously but I am still having issues with this.
I know many of you have advised putting an alarm through the phone system is not the way to go but the customer is still insisting despite repeating it is not the way to do this.

Please could someone explain how to get round the following issue;

Currently the mobile number is pre-programmed into the alarm system and this then gets dial tone and calls out through a BT analogue line. A two wire BT telephone cable is fed through from the alarm to the back of the BT analogue box and then crimped down onto two of the pins on the phone socket which then dials out to the mobile.

The issue is what to do next?? I am thinking if I take the two wires out of the back of the phone socket and crimp this down onto an RJ45 somewhere?? (Any advice on that would be great as there is only two wires but 6 places they could go)then plug that RJ45 into port 7 or 8 of the Avaya combo card that would then connect the line to the phone system. But then there is the issue that the alarm is tring to dial a mobile number? So surely this would create an issue when the Avaya tries to call the hotline??

Any ideas on how this could be achieved would be great.

Thanks inadvance;

You said there are 6 places they could go. Do you mean the pin out on the RJ45 (although there should really be 8 places)? If you do, put the 2 wires on/in the center pins (pins 4,5). If the system is using an auto-dialer, just have it so that when the extension picks up it goes to your ARS table.

So under User for your analog extension (create one if it's not already there) go to your short codes tab and enter

code --------- ?D
feature ------ dial
Tel No ------- .
Line Group --- 50 (or whatever your ARS is)

You can also do it like

code --------- ?D
feature ------ dial
Tel No ------- N
Line Group --- 1 (or whatever your outgoing trunk group is is)

There are lots of variations, but hopefully you get the gist.

Hope that helps

In all my cases where a trunk is being used for an alarm panel and a PBX we install a RJ 31X (alarm jack) where the dial tone feeds into the jack first and then in return it runs back out to your systems trunk port. I'm also in the US so I'm not sure if it's the same process in the UK.?

Same in Oz norstar.

Dude alarm line work is basic stuff. It's also called a mode 3 connection. You might get results searching security socket in the cabling forum.

So a wobble on the ipos kettle cord and you're alarm's f*cked too?
Power surge? Ginger kids at the switchboard? 'What f*ckwit did that?' they'll say.
Analogue extension for premises alarm. NONONO NEVER. NEVER. NEVER

(twitches eyelid)

or as Aacon once quoted Back away not today disco lady.
Use a mode 3 socket
