Many thanks to all the people that replied to my panic alarm post.
Just to go through the suggestions,
I have an electrical opening and closing security door.
I have CCTV that is connected to an alarm company.
Automobile alarms here are a dime a dozen and go off every time a
loud Harley goes past, so no one reacts. Ever.
Hand held sirens or whistles are not loud enough for what I have in
mind.
I love dogs, but to tell Fido that that nice 'lil ol lady that has
just pulled out a 9 mil snub nose is actually an armed robber is a
bit difficult= … ( I’m kidding, but you get the drift)
Daniel Spirer made a very good and pertinent point.
Generally speaking, panic buttons should be used only AFTER the
criminals have left the shop. If you use one while the criminal is
still in the shop, and the police show up, you are in a hostage
situation suddenly. Similar thing if you have something that goes
off right away. The odds that the criminal will do something far
worse go up dramatically in those types of circumstances.
This is very true.
It goes hand in hand with not making eye contact with the robber,
obeying and keeping your voice down and not acting aggressively.
All these action will increase your chance of survival in a desperate
situation.
In St. Maartin, however, the situation is somewhat different.
One is not allowed to own a gun of any sort.
In fact, a citizen is not allowed to be armed with any type of
weapon, be that a gun, knife or pepper spray.
This obviously puts one at an immediate disadvantage against a
criminal, who does not suffer from those restrictions.**
So when a 5 foot, slightly built women gets attacked by a 200 pound
6 foot 6 knife wielding thug-- to put it delicately— the doodoo has
hit the fan…
And that is when the button must be pressed. There is no hostage
situation to speak of.
It will be used during a violent attack on a person.
The police in St Maarten are incompetent and corrupt.
A joke, compared to the police in America or other western
countries.
They often don’t answer their emergency number, or sometimes late at
night, there is an answering service. (I am not joking)
Press 1 if you have been shot, press 2 if you have been robbed (I
amjoking)
So here is the thing.
Essentially, what I needed was a wireless on/off switch.
I am going to make an independent mains and battery driven alarm
that is switched on only by a hand held alarm button. (I will remove
the off part)
The unit will be mounted in an area, be that outside or near the
ceiling that is not easily accessible.
The off switch will be only accessible on the unit, not from the on
button, so when the button is pressed, the only way to switch is off
is to get a ladder and switch it off manually.
I am going to use one of those air compressor driven fog horns.
I want it to be ear shatteringly loud.
That way there will be no confusion between car alarms and tweety
hand held alarms.
I will do a Hidi on it, and post on my Orchid Blog, so that other
jewelers that are in the same third world situation like me can build
one as well, should they want to.
Thanks to all that responded to my question.
Cheers, Hans
