Speech Diallers

[james.wilson]

i said id back out but you cant use a dialler and prove a successful transmission. If you could we would all use them instead of digi's

[truesecurity]

All valid points,

The site in question is on an industrial estate, the keyholding company are on the same estate. They could probably hear the sounder from their office !

Is there a dual path dialler available anywhere ? The risk of losing the phone line is the same with a digi, even if you have an auto test call every 24hrs. Ok so the digi will pick up the fact that the customer has not paid the bill for 'that other phone line' that the accounts department weren't told about.

But if the line is cut just before an attempt at burglary, the result is the same whether digi or dialler surely ?

if its at that level of risk then you shouldnt be using a dialler - simple really

[james.wilson]

agreed if the line is at risk or the line is a likly target due to the value of goods etc, then the ra should pickup that a dual path signalling device is needed. The fact you started with a dailler i would hope its a very low risk site

It is a low risk site, they make odd shaped cardboard boxes ! Not too much to steal, unless you're homeless I suppose.

If it was a higher risk site with any chance of a line being cut I would say Redcare at the bare minimum, preferably Redcare GSM.

It was a kinda digi or speech dialler question really.

[kensplace]

Not having used a digi, how does a digi prove a successful transmission?

Is it there a acknowledgment signal sent back to the digi from the arc, if so is that done automatically by the hardware/software protocol or does the operator manually acknowledge reading a successful alert?

[james.wilson]

you get a successful 'kiss off' from the arc reciever, and all that is logged by closed devices etc.

The dualcoms and redcare's have additional logging.

Nothing is dependant upon any manual intervention.

[kensplace]

So after the 'kiss off' your system knows that it has done its job, and any failure to respond is purely up to a problem at the arc end. Sounds like a decent way of doing it.

I guess with a speech dialler, you can only get a manual ack from the receiving end if they are going to bother doing something, so they could always say the could not hear anything, or the line was garbled etc and not bother to acknowledge.

Shame the arc's dont have to record all calls as standard, and monitor the phones on cams (with audio) so it could be proved someone there did not answer the phone, or that if they did, the message was clear and understandable........

[james.wilson]

nacoss gold arc have to record all calls, but not the transmission lines. Yes a panel will log a comms successful with a digi, and also a 'comm fail' This used to remove the 10 min bell delay in days gone by.

But you could use it to activate another signalling path is required. But to be fair a few hundred quid for a dual path comm shouldnt really be an issue for security unless whatever is being protected isnt that important.... then no need for a system at all lol

[arfur mo]

not done often today since redcare and dual com, but digi's can use a 'return path' signalling.

site is set in the normal way but the exit tone did not stop until CS (Central Station back then) acknowledged the setting signal, proving comms and phone line were active both ends. same thing happened when they open up.

was used also to make sure nobody forgot to set the system un-noticed or unauthorisedperson sneaked back with keys and a code as the time window limits were set with 1/2 'grace'.

if you needed to return you had to phone the CS with a password and code prior.

you can set the comms to signal at regular periods, so yes the line could be cut but at least the client would be informed within the the period not longer than the test calls.

might fit the bill if alarm is not for insurrance, but its your risk assesment so get it in writing for client acknowledegemnt and agreement.

before anyone thinks of having a pop saying 'no longer used bypro registered firms' , there was a thread last year where a chain of supermarkets was using digi's, the manager came in here was concerned about comms not received for open/closed.

the above would have resolved it, and setting could also have been confirmed with a text mesage to the keyholder/s - OK!

(you need to advise client of phone call costs)
