i've done dozens of rooftops over the last few weeks, all new, and quite a lot had " this door is alarmed 24hrs a day - exiting/opening will trigger alarm " type warnings. Only twice has an alarm actually sounded and both times the alarm stopped the second the door was closed ie the circuit was closed again. Neither time did anyone come to check. And at least once when through the other side of the door i could see the cord leading to the reed switch had been cut disabling the system altogether..which was great because actually it was the best rooftop i've done in terms of rewards.
flipside is some friends did a rooftop recently and when they reached ground floor door seccers were waiting on the other side for them, silent alarm. that's the real trick, the reed switch or sensor that you don't spot. all ended well, but the moral here is it's what you can't see that can screw you.

| | | | As an alarm installation tech, I can't tell you how many people (including large businesses) try to save money with a "DIY" alarm project. In a majority of cases, the installers are not well versed with electrical circuits and alarm programming. As a consequence, these systems may generate false alarms, or even fail to function at all.
Unfortunately (or fortunately - depending on which side you're on), with a professionally installed system, it is difficult to defeat the technology itself as they are generally "cross zoned" to prevent false alarms.
As far as the exit doors are concerned, once the circuit is broken, a relay should active an external power supply and siren to prevent it from discontinuing when the door is closed again.
I would love to talk alarms with you all some day!

| | | | Also used to be an alarm installer. If I alarmed it, you wouldn't be just getting it open.
Many of the exit alarms are standalone "crash bar" type alarms. I believe they have both methods of operation, switched with a key... off/alarm only when opened/alarm latches on when opened. As stated above, your situation may vary with DIY type stuff. You don't want to see my idea of DIY alarm systems.

Security done right is never easy to get past. I've had my own ideas about DIY alarm systems - especially ones for tunnel systems that look around corners.

| | | | Only when stupid people DIY... lol... if I wanted to keep you out, believe me, you'd stay out.
For example, appropriately designed trip lasers are almost impossible to bypass, and can be wired to a siren which will stay on, or even to play a prerecorded message over a phone line. (some dtmf tones to dial perhaps?)

| | | | I hope you're joking about the trip lasers. Those are so difficult to install, align and maintain that they are not worth the effort. An entire room full of laser beams can be replaced by one strategically placed dualtech motion detector at a fraction of the setup cost, and with practically zero maintenance.
Now, if you were talking about a DIY laser system with a 50W CO2 cutting laser that would dice intruders as they stick body parts into particular openings, now we're talking sensible! Also applies to 12KV bus bars just inside of window openings, shotguns pointed at door openings, etc.

| | | | haha, a 5mw infrared laser, and a cellphone camera... high tech mann... it's just a matter of making mirrors stay solidly. 
of course the more fun approach is to use a crappy computer, a webcam, and an arduino to attack intruders with airsoft pellets.... and yes, there are good ways to identify whether the thing moving is human. If I weren't so damn lazy I'd be dicking around with an ardy right now...

| | | | LOL! You and me both on the Arduino. Got one for Christmas, but haven't had the time to break away from all the other crap I gotta do to stay afloat financially.
Would be pretty awesome to set up a solenoid in a building to knock at the structure once in a while to spook the hell out of people. Maybe a couple of them that would listen for each other and start up a conversation in morse code.
Airsoft... bah... paintball. Much more fun.

|  | | | Got a question for you alarm geek-types. The below image is of a sensor that being used in an vacated power station. I was wondering if anyone knows the manufacturer
(Note:Images cannot post, file size to large.)
