Enter Key (ent)

The ent key accepts and processes entered data. Valid actions are performed and the next option is accessed.

Escape Key (esc)

The esc key aborts the current option to return to the previous option level. Any option modification made prior to the option being aborted is erased. Successive pressing of the esc key returns the user to the start display (known as the BANNER).

The esc key also aborts the setting routine if pressed during the exit time.

Hash Key (#)

The # key is used to display additional choices for certain options, e.g. ADVANCE/RETARD the time in the Time/Date option.

This key is also used as the user duress key (by pressing twice following a valid code entry).

Star Key (*)

The * key is used to provide additional features for certain options, e.g. printing the event log or deleting entries.

Power LED

The green power LED remains lit whenever the keypad is connected to a mains power supply. A mains power failure is indicated by the LED flashing slowly. The LED flashes rapidly if the battery voltage falls below the minimum threshold or if one of the fuses on the control panel PCB blows.

Banner

The banner is the display shown on the keypad, e.g. Galaxy 520 V5.00 (with the time and date on the bottom line). This is shown at all times when the system is unset, unless the menu is being accessed or an alarm or help message is on the display. The banner can be changed by the engineer. In the set condition the banner is normally blank.

User Codes

The user code is a unique PIN (Personal Identification Number) of at least 5 digits in length. The PIN identifies the user to the Galaxy Alarm panel and allows operation of the system.
