Is the keypad protected against damage caused by discharge of static electricity?
A. Yes! The STORM keypad not only protects itself and the host system from static discharge damage, it also protects the user. As a potential user walks toward a terminal he/she may be generating static charge. Non-conductive flooring, clothes of man made fibers, even dry atmospheric conditions can combine to create this hazard. Charged with upwards of 50,000 volts the unsuspecting user reaches out with their hands to operate the keypad. If the keypad is simply ‘grounded’ to wick away the charge (as most vandal resistant keypads are) the user will experience a severe if momentary electric shock . The user’s perception is usually that he/she has received an electric shock from the terminal (rather than having just given the terminal a shock). To reduce this risk STORM keypads feature keytops (usually the first point of finger contact) that are held in isolation from other conductive and grounded components. This does not completely eliminate the risk of static discharge however it does
