Arming Devices and Systems

Many types of explosive devices (both improvised and manufactured for use in military “ordnance” items), contain a single device or a system that temporarily blocks detonation. It is referred to as an arming device if it is a single component or arming system if it is multiple components.

Arming devices may be set to initiate/detonate the explosive (“become armed” and thus on standby) manually, or by some other means, such as time delay.

The various mechanical, electrical, electronic and chemical devices we offer in our inert product line clearly demonstrate to students how arming devices work and the hazards inherent in many of the improvised types.

CLOTHESPIN/CIGARETTE DELAY
Order Sku: ITA-100
Clothespin/cigarette delay. Clothespin is modified into electrical switch, which closes as twine burns through from cigarette.

Price: Request Quote

MOUSETRAP/SOLDER DELAY
Order Sku: ITA-101
Mousetrap/solder delay. Same principle as ITA-98. However, this device uses a powerful torsion spring that can close a switch as well as fire a percussion-initiated bomb.

MOUSETRAP/CIGARETTE DELAY
Order Sku: ITA-101A
Mousetrap-cigarette delay. Operates on burn-through principle. Same principle as ITA-100.

ELECTRONIC DELAYED ARMING, RADIO-CONTROLLED IED
Order Sku: ITA-102
Electronic delayed arming, radio-controlled IED. This device is a modified command detonation bomb model which can not be detonated at the exact instant the joystick control is operated. The joystick control simply starts an electronic automatic arming sequence. This is a safety feature to prevent (or at least attempt to thwart) electronic countermeasures jamming by a scanning transmitter moving up and down the radio frequency channels. Once the firing sequence has been started by the bomber, the bomb will detonate only after the electronic arming delay has set itself; the delay is variable and is set by us at the factory to the user’s request (typically 8-10 seconds to thwart a sweep by E.C.M. equipment). Transmitter is handheld, portable, with range variable from 1/4 mile to 1 mile. Receiver uses dual servos for redundancy, contains detonator and simulated dynamite or plastic explosive, LED, and whistle.

TEMPERATURE SENSITIVE RISE
Order Sku: ITA-107
Temperature sensitive Rise. Demonstrates that a rise in temperature can be used to initiate an IED. Device is connected to relay and uses two power sources.

Price: Request Quote
Quantity
TEMPERATURE SENSITIVE DROP
Order Sku: ITA-107A
Temperature sensitive Drop. Demonstrates that a drop in temperature can initiate an IED. Can be used in refrigerators and air conditioners.

LIGHT INTENSITY FALLING
Order Sku: ITA-111
Light intensity falling. Operates in same manner as ITA-110; however, the unit uses a different photocell and the logic unit is wired to sense change in resistance through a drop in light intensity

Price: Request Quote
Quantity
INFRA-RED LIGHT SENSITIVE
Order Sku: ITA-112
Infra-red light sensitive. Contains special photocell particularly sensitive to infra-red light.
Note: This device works particularly well with infra-red output sources, but it also functions acceptably with many types of visible light.

HUMIDITY SENSOR
Order Sku: ITA-116
Humidity sensor. Uses commercial humidity sensor and is designed to initiate detonator as relative humidity changes.

Price: Request Quote
Quantity
Arson IED using Propane Tank with Kitchen Timer Delay
Order Sku: ITA-117
Built around plastic gasoline container, propane tank, oxygen tank kitchen timer (see ITA-148 & ITA-150).

Price: Request Quote
