Chapter 3 - Connecting and Installing Your Impulse
3-7
C. Connecting an IDC Keypad
Two versions of IDC keypads can be used with the
Impulse drive. The FP100 works only with the
Impulse, while the FP220 can be used with the Impulse
as well as IDC’s Smart Drives (see keypad-specific
information below).
The COM PORT on the front panel of the Impulse is
used for connecting either version of keypad.
Power is applied to either version of keypad when
power is connected to the Impulse.

Connect the FP100 Keypad to the Impulse with the
cable supplied with the keypad.
