NOTE:  Up to four (4) keypads may be added to this panel. The 49-452 and
       49-484 are the only acceptable keypads for this panel, as this 
       keypad uses a PROPRIETARY data protocol to communicate to the panel.
       Keypad Addressing:

Keypad Addressing:

Keypad #1:  SW1 Off,SW2 Off 
Keypad #2:  SW1 On, SW2 Off 
Keypad #3:  SW1 Off,SW2 On 
Keypad #4:  SW1 On, SW2 On 

Keypad Note:  The alarm center recognizes all connected keypads when it is
              first powered up, and then responds ONLY to those keypads. 
              All keypads must have a unique address.

Changing Pass Code:  With panel DISARMED, and no zones violated press and
                     hold the "*" on the keypad until the LOOP indicator
                     slowly flashes.

Within 30 seconds, enter the old password (default is 1234), the LOOP
indicator will go out, then enter the new pass code.  The LOOP indicator
will go on again.
