Ohh yeah we also have panic buttons on the wall...forgot to mention that...basically they press it...I assume a small buzzer goes off in the main office and an LED might light up for the classroom location...then the principal will call and ask or send someone...

I am thinking it is something like the alarm companies already have with many systems they sell in that the homeowner would press thier fob that they have hanging around thier neck and that would alert the security company and they would send someone out to investigate.... but I am not quite sure how that works... and if you have two houses right next to each other, or apartments, and each has that same system, how would the alarm company know which place to go.... it seems like they would have to be matched to thier system somehow...
Cheers!!
Yea I'm thinking that each room would have the fob this way they would know where to avoid or send a response team.This application could also work for the Violent students.
My anunt's School has around seven class rooms but the system would be able to be expnded on.

All the teachers could just carry mobile phones, if there's a terrorist warning the head teacher could just bulk send a warning text message to all the phones.

Thanks for the response but I think it would be hard for a teatcher in trouble to send a text,also keeping it instant and descreat is the key.

Isn't there a way to program it to send a canned text message?

Alright may be not mobile phones but what about PDAs?

Some even use the Linux operating system which is open source so I'm sure there's a way to hack it so when a certain key combination a canned text message is sent to all the other phones.

What about walkie talkies?

Some have a morse code function which could be used a an SoS function.

I was thinking that a key fob would send it to a central security\administration area.... And they could bulk send a message to like a text pager or something.... That way a human is still in "The Loop" assessing the situation... but the main thing is a way to tell which fob was activated so there is a way of telling where the trouble area is... I am still thinking on a solution there...

Do more strict in the gate. Check weapons, Unknown persons, Be vigilant etc…
Call for emergency in a situation like that.Nothing else.

How about allowing some dogs, goats, sheep or the like to roam the hallways? Animals always have a sense for danger. They'll warn the staff of an earthquake, a sudden and deep drop in barometric pressure, a solar eclipse, etc. All that they ask for in trade is some food/water bowls left out for them and a janitor with a scooper and a trash bag. They could also be trained to bark loudly at students lurking about the halls trying to skip class.

walkie talkies are bad ideas. Its too easy to scramble the signal...

Hello
I think I already have a device in mind.I think I will go with the fob and panel.

Like Eric says the difficulty is the strength of the RF. signal so a device like in the link will allow the signal to be carried through the Schools internal wiring-

When the fob is pressed the receiver that will be situated in each room will pick up the signal with no problem it will be then sent via the internal wiring to the receiver that will be situated at the main desk and maybe the headmasters office.

I have drawn up just a little drwg. to show how simple this should look.
The next step is to create a working model.Due to my lack of Electronic experience I would be grateful of any advice and tutorials that will aid me make this up.

Thanks and Regards Mark

Ps. sorry about the simple drawing

Who's gonna make sure the batteries are always working? Or if there are signal reception problems? A couple of Schutzhund trained German Sheperds or Rottweilers roaming the halls will assure compliance from everyone.... even from the lazy janitor that tries to sneak in a snooze after hours!

A key fob souds one of the best solutions offered so far as it's fairly easy to get hold of both of the key fobs and the reciever modules; they are also encrypted to so it's pretty hard to fraud.

The batteries in the fobs would last ages and the transmitter via the internal 240v circuit would eliminate this and help signal strength too.
