Recently this popped up in IPVM's Facebook feed:
Is this true? Are ADT alarms usually delayed by 45 seconds before the dialer sends the alarm? When would this be the case?
Especially for cell backups, what is common delay between local alarm and monitoring station notification?
I thought most alarms had a delay to give the user time to enter a code/disarm the system.
Certain modes and types of alarms might include a 'user' delay.
For example, an alarm from the front door contact might include a delay, but if a motion sensor upstairs trips, or any other sensor, there is no delay.
Also 'Home' vs. 'Away' arm states can be a factor. If armed to 'Home', the alarm has no delay. If 'Away', there might be one.
But in either case, that's pre-alarm activity. Not a delay after an alarm is already triggered.
I can't speak for every area, but all the ADT takeovers I did when I worked residential alarms had a dialer delay programmed in. Applied to all signals. So once the bell goes off, in the case of a burglar alarm, system waits 45 seconds before attempting to dial. If the system is turned off in that time, no signal sent. That's 45 seconds ontop of any entry/exit delay, which I've seen some people ask for ridiculously long entry delays, just in case "I forget something".
Can't speak for Vivint, but their predecessor, APX, had dial delay built into the Honeywell Lynx systems they installed in my area. Once they changed their name to Vivint and started using 2gig, I don't know. We didn't even attempt to take those over, since most of the time customers canceled quickly, and the equipment was taken by Vivint.
With no dialer delay built in, it's still not instant transmission. On a POTS line, usually took about 35 seconds from start to end for a single signal. So that's the panel picking up the phone, dialing the number, reaching the receiver, giving the information and getting the kiss off.
I only really work with alarmnet for cell communicators, it's faster, but still not instant. Same with internet monitoring through alarmnet.
I mean you can go further, then you have the delay of the signal going from receiver to software (usually hardly anything) and the "delay" of how long it takes the operator to fetch the alarm, go over instructions and start calling. And that just varies by how busy the monitoring center is. I'd say a good average response time from alarm trip to phone call, with no built in delays, probably 3 minutes. But I'm just guessing, and that will vary per company, and even per operator.
Alarms all have zone's that are instant alarm and those that are programmed with an entry exit delay.
Outside of the entry exit zones with a delay, all other zones would be instant alarm.
aside from that, in the instructions, for an given account (insert integrator name here) may right into the dispatching instructions that they do not call the customer or key holder for a certain period of time. While at my last employer we ran into an issue that JCI would every once in a while not notify us of an alarm for 30 minutes. Somehow they would every once in a while include do not notify for 30 minutes into our customer profile. We would have a burglary alarm go off and be told 30 minutes later. This would happen every so often.
I can also say that when TYCO IS (prior to JCI) did away with their online account monitoring system (forget the name), the system prior to the existing platform Datasource, and moved to Datasource, the alarm history was delayed by 15 - 30 minutes in some instances. When speaking with TYCO IS representatives they stated that it was for a legal reasons and the new platform Datasource was intentionally programmed with a delay in the reporting or populating alarm history/activity due to the liability if they provided real time alarm info to customers.
There are different delays on an intrusion system like the posters above have brought up. Most alarm panels (I haven't touched burg in over 5 years so I'm out of touch) have the option for dialer delays for various signal types like alarm, entry/exit doors, or single trip fire alarm. Some signal types would bypass a dialer delay though, like duress, panic, or confirmed-fire/gas alarm.
Local cities banded together to create what they named a "F.A.R.T." (False Alarm Reduction Team) with local police, dispatch centers, and alarm installers. The reason for the dialer delay deployment was due to so many users triggering the alarm through operator error and only knowing the alarm was set once the siren went off. The PD's were disregarding most call center alarm calls because of this and then imposing large fines to the users. I remember having to start setting delays to 30 seconds beyond the entry time in certain areas or the city would not issue an alarm permit for responding.

You're joking, right?!
That is the acronym they wanted to use.
i find it amazing that some people continue to make puerile fart jokes well into middle-age without shame.
they just let'em rip!
I am a noob when it comes to alarms, but why wouldn't the system use some type of verification method?
IE:
Any zone goes off. The alarm establishes connection receiver.
If: Code entered in X time send 'all clear' to receiver.
Else: No-code entered in X time, or lost connection with alarm panel. Confirm alarm and pass information to central station.
That's basically what the delays are doing. Entry/Exit delay is saying "No code in x time, turn on siren, send alert". Dialer delay is added ontop of that, shifting the alert period. So Entry/Exit now says "No code entered in x time, turn on siren, start dialer delay". Dialer delay, the siren is going off, and it's going "No code entered in x time, send alert".
Receivers are built to receive. It can't sit there with an active connection established, but not receiving any data, it's pointless. It would be like you getting a phone call and it's just silent for like a minute. You're going to hang up.
Ahh. So I assume the receiver is dumb in this instance and can't hold 59 ticks of 'OK Clear" and 1 tick of "Not OK Alarm" to get rid of the dialer delay.
Thanks for the clear explication Daniel.
that's what the old systems with a dial-up modem do:
Event 1: the door with a delay assigned tripped - start the timer
Event 2: timer = 0, no code entered - the panel starts dialer delay timer (could be set to 0 sec) and activate the siren
Event 3: dialer delay timer = 0 - start dialing the monitoring station.
The newer panels with the digital comm channels have some protection mechanisms, like APL from Honeywell, for example. After event 3 + APL delay timer the Honeywell server will send an alarm to the monitoring station if there were no signals received from the panel. But there's nothing you can do to protect the old ADT system. The intruder will have a delay (30-120 sec typically) + dialer delay (45 sec) + connection/transmission time (5 sec at least) to find a panel and unplug/cut the wires.
Why do they do it? They want to decrease the load on the call-centers, as >90% of the calls are false alarms.
Most Central Stations have a cancel period, it's usually 60 seconds. This means that even if they get an alarm, if a proper code disarmed the panel within 60 seconds of receiving an alarm, no Operator Action is required. If you add in the Entry/Exit time of (typically) 60 seconds, that means that you have a delay of 120 seconds from door opening until dispatch.
Factor in that some panels can be programmed to delay dialing out for 45 seconds, and you have a recipe for disaster!

I wouldn't say disaster. I mean in most areas you're lucky to get a quick police response for a burglary alarm. Yeah I guess every second counts, but in my area unless it's some high security area, by the time the police show up, the person causing the alarm is long gone.
Or if they only trip a door, you won't even get cops in my area. Need to have two separate zones triggered.
One of my biggest worries is a thief who knows enough about alarms (which is to say, the basics) such that they enter and locate the panel within the entry time and vandalize it before it can send an alarm signal.
We just completed a camera install along with an alarm for the NVR room. The building is in a bad neighbourhood with a very high incidence of crime and vandalism. The room is small enough that we had nowhere to hide the panel, so we set both the PIR and door contact as "perimeter" alarms with no delay. If the alarm isn't disarmed BEFORE entering it will immediately send an alarm signal. We expected the keypad would get vandalized too so it's inside the room and all arming/disarming is done exclusively with fobs. This is the second such building we've set up this way and found it works well, with the building owner keeping a fob, a trusted on-site caretaker with another, and however many spares they care to pay for.
For buildings like this we usually recommend IP monitoring with a GSM backup. It's an easy sell when you remind them how much hardware they have to protect in there. I'm all for repeat business but I'd rather not get it on account of them having been victimized.
You could try a box within a box kind of thing. A russian doll of alarm panels. I know it sounds like a joke, but Alarm Panels are usually pretty weak, even with a key and screws it's easy to get into.
But perhaps putting it inside of a slightly larger box made from a stronger material, with a key, or security screws...would make it tougher to disable when you cannot hide the panel in any other way.
We had thought of that, and we mounted a lockable rack for the NVR and UPS but there wasn't enough room left to stuff the alarm in there as well. I think for this particular installation the instant-alarm is enough of a deterrent; in the few times the alarm has gone off for other reasons the perps have vacated right after, and I suspect anyone breaking into the room is not expecting a 30W siren immediately going off right above their head. :)
