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.

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. Demonstrates that a rise in temperature can be used to initiate an IED. Device is connected to relay and uses two power sources.

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

Humidity sensor. Uses commercial humidity sensor and is designed to initiate detonator as relative humidity changes.
