5.9 RESETTING FACTORY DEFAULT ACCESS CODES
If a code number is ever lost or forgotten, codes may be reset to factory default settings through
the following procedure:
• Open the main cover of the Detection Unit;
• Remove the three (3) screws that hold the Controller Circuit Board cover;
• With power connected and the unit in its Operate Mode press the Access Code Reset button in
the upper center of the circuit board.
• ACCESS CODE #1 will again be 1234 and ACCESS CODE #2 will be 5678 .
SPECIAL NOTE : For maximum security it is recommended that both Access Code numbers be
changes from the factory default settings and that the numbers be known only to those who use
them. Record the new code numbers on the Access Settings card that accompanied this Owner’s
Manual. It is also suggested that codes be changed periodically, especially when any changes are
made in personnel with access to the codes.
