Barometric and Altimeter Armed/Initiated Devices

IEDS have been made and used in a number of bombings where the initiating system was based on a modified barometer or altimeter.

Securesearch offers several such inert training devices that function electronically based on change of air pressure / change of altitude of an aircraft.

Some such devices are armed by one barometer and fired by a second barometer or altimeter.

As these instruments are commonly available, security personnel—particularly airport luggage screeners—must be trained to recognize them as IED components, or their place in assembled IEDs.

ALTIMETER SWITCH INITIATED IED
Order Sku: ITA-115
Altimeter switch initiated IED. Built around functioning aircraft altimeter on 2’ X 2’ display board, with stand. Uses small electric (120 volt) vacuum pump to exhaust air from altimeter; simulating a rise in altitude, as if installed in an aircraft which is ascending from ground level. Where available, we also attach to the board a set of working parts from the inside of an altimeter to illustrate their appearance and demonstrate their functioning.

BAROMETRIC ARMING / INITIATING DEVICE
Order Sku: ITA-142
Barometric arming/Initiating Device.
First barometer arms the device by triggering an indicating fuse. At later change of air pressure, second barometer initiates a detonator.
