defusing with button (models AST-3XX)

button nr. 1 (the left one) has to be pushed for as long as it has been set (5 to 30 seconds)

defusing with key only (models AST-311 and AST-321)

the device can only be activated or defused if the player has the key to enable the buttons

defusing with wire only (model AST-321)

the device can only be defused using the 3 wires but, in this case, there is a chance that the device will go off ("explode")

defusing with key OR wire (model AST-321)

the device can be defused either if the player has the key to enable the buttons OR using the 3 wires but, in the latter case, there is a chance that the device will go off ("explode")



for models AST-3XX

If countdown sound is eliminated, the device can be used as a simple timer that does not need to be defused. (In models featuring the key switch option, the buttons can be disabled by the key switch if required in order not to let anyone try to stop the countdown.) This feature can be used when all you need is to know when a certain amount of time has passed (in a time-limited game or round, for instance).


for models AST-3XX

the following parameters can be modified:

countdown time between 1 and 99 minutes in the following increments: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95 and 99 minutes

defusing time between 5 and 30 seconds in the following increments: 5, 7, 10, 12, 15, 20, 25 and 30 seconds

game mode (for model AST-321): button only OR wires only OR button or wires

sound settings (for models AST-3XX): sound alert upon explosion, defusing and countdown

economy ON/OFF: economy ON makes the countdown numbers disappear from the display after 15 seconds, but they can be brought back anytime by pushing either of the buttons

DEFUSING THE DEVICE USING THE 3 WIRES (stopping the countdown)

only for model AST-321

When defusing using the 3 wires, there is always a risk that the device goes off ("explodes") as it is not known which wire will execute the explosion, the defusing or making the countdown twice as fast, because the wires change order at every newly started game.


for models AST-311 and AST-321

The key switch performs a very simple task, it disables the two controlling buttons by breaking the circuit when set to zero (red) position.

Models that feature the key switch (models AST-111, AST-311 and AST-321) are always delivered with 2 keys (one for each team).

If you play a game in which the keys are in use, both the activating player and the defusing player have to use their key in order to access the device. This is a hardening element during the game and it also means that these players need to be well taken care of by the fellow players so as not to be hit, otherwise the teams cannot achieve their tasks. © 2010
