Double push panic attack button (PA)

This is a small box shaped device, with two red buttons on one end.   If you want to set off your alarm (even when it is unset) simply press the two red buttons in together (using two fingers simultaneously).  Some alarms are programmed to have a silent PA button which means there is no sound whatsoever at the site if the button is pressed.  Other sites have the sounders activate immediately the button is pressed, and some have a delay before the sounders activate.  Each site is different depending on the needs of those that might have to press the button to summon help. 

If you have a look at the picture you will notice a small red-filled hole in the top.  This is usually green/yellow and it turns to red once the button has been pressed.  After the panic button has been pressed the alarm panel cannot be set until the panic attack button has been reset.  To reset it a small key is used (see the keyhole in the device on the picture).

Response to a panic attack button being pressed can: ring the siren outside, call the keyholders, or call the Police.  All this even when the system is not set.  Similar devices can be used to summon medical help for elderly, ill or disabled.
