Chapter 3: Programming the unit
40 LaserSense HSSD-2 Aspirating Smoke Detector Installers Handbook
Valid ranges for all programmable parameter values are displayed in
parentheses below/beside the parameter legend in Figure 29 on page 41 and
Table 3 on page 43.
Note: You cannot save an illegal value. For example, the maximum valid input
for the Fire 1 level is 10. If you enter 99, the programmer displays the Bad value
error message, and prompts you to enter the value again.
After you enter the required value, press the <Enter> key to select the amended
setting. Pressing the Right Arrow key when the cursor is on the right-most digit
has the same effect. If no programming activity is detected for 5 minutes, the
detector displays the legend Access timeout and exits Programming Mode.
Main menu
When the correct access code is entered, the display shows the main menu. The
current selection is always shown with an arrow after it. Press the <Enter> key or
the Left Arrow key to activate the selection.
The choices available in the main menu are, in order:
Setup Menu: Contains all the user-programmable functions.
Log Menu: Displays historical information such as the event log (time and date
of various events such as alarm or fault conditions).
Diagnostic Menu: Contains detector self-tests.
Reset: Clears any latched fault readings or exits from a menu item to its parent
menu. This has the same effect as pressing the <RESET> button.
Isolate: Isolates the detector. This has the same effect as isolating with the
<ISOL> button.
Exit: Exits Programming Mode
Note: When you press the Up Arrow key in the Setup Menu, the main menu
wraps around and brings up Exit, etc.
Navigating through the menus
Press the Up and Down Arrow keys to navigate through the main menu options.
The currently selected item appears at the top of the screen and is identified by
an arrow or a trailing dot.
Figure 28 on page 41 shows how pressing the Down Arrow key scrolls the
screen from the Setup menu (the current selection), to the Log menu.
Alternatively, pressing the Up Arrow retreats to the Exit command.
