2.2.6
PROGRAM
When this touchpad is pressed, the settings for Program and Sensitivity will appear on the LCD dis-
play.
SPECIAL NOTE:
The above touchpad functions will be available to operators of the detector at all
times. Additional functions such as program and sensitivity settings and other adjustments neces-
sary only at installation time may be selected by pressing the
ACCESS
touchpad and entering a
security code.
2.2.7
ACCESS
The
ACCESS
touchpad will be used only by supervisory management personnel. It permits chang-
ing the Program and Sensitivity codes and also is used to control such functions as synchronization
of multiple units, pulse frequency, tone, etc. (See Section 5.3). The unit further protects security of
control settings by maintaining a non-resettable sequence code that indicates any attempt at seek-
ing access to the settings. When this touchpad is pressed, audio of the system will “chirp” and
ENTER CODE will be displayed on the LCD, prompting the operator to enter an access code. If no
attempt is made to enter a code, the unit will continue chirping for ten (10) seconds and return to
Operate Mode. If the operator enters an incorrect code, audio will sound a Tamper Alarm and
ACCESS DENIED will appear on the LCD for five (5) seconds. An asterisk (*) will appear on the
Sequence Counter indicating that an unsuccessful attempt has been made to access the Installation
or Program/Sensitivity Modes of the unit.
Operator’s should never touch this control. If an operator should inadvertently press the
ACCESS
touchpad, no further action should be taken and the unit will return automatically to the Operate
Mode in about ten (10) seconds.
