Hidden Display Mode
The Matrix alarm panel incorporates a hidden display (confidential mode) feature, that can be enabled /
disabled by your installation engineer.
This feature basically hides all of the panel information from the LCD keypad display if the keypad has not
been used for the last 20 seconds. In hidden display mode only the time & date will be displayed on the LCD
screen and only the supply LED will operate. On all other keypads only the supply indicator is operational.
If there are any latching alarms present (Denmark, Norway, Finland & Sweden only), then the keypad will
not go into hidden display mode. You must reset the latching alarm before hidden display mode will be
allowed to hide the display.
The keypad will remain in hidden display mode until a valid user code has been entered on the keypad.
Depending in which state the alarm panel is currently in, the first valid user code entry whilst in hidden display
mode will have the following effects on the panel:
When Disarmed
If there are no system faults then the panel will come out of hidden display mode and automatically start
the arming process.
If there are any system faults pending then the keypad will drop out of hidden display mode and allow
the system fault to display. The panel will not start the arming process until you re-enter your user code
again.
When Armed
The panel will come out of hidden display mode and start the disarm process. For single partition
keypad/user combinations this will result in a full panel disarm.
When In Alarm
The panel will come out of hidden display mode and drop into First To Alarm (FTA) mode.
When In First To Alarm (FTA) Mode
If the keypad is allowed to drop back into hidden display mode whilst in FTA mode, then simply enter
your user code again to re-display the FTA information.
