2.2.1  Internal keyboard 

The table below describes the keys of the internal keyboard of the control panel and their function. An icon on the front panel of the 
control panel is associated to each key. Just for convenience, a name is associated to each key as well. These names will be  used 
throughout the document to refer to each key.

If the passwords are enabled, the user is required to enter the level 2 password. 
The usage of this key leads to the storage of an event in the event log. 

 

SKIP DELAY 

This key zeroes the running activation delay of the siren outputs. 
By  pressing  this  key,  the  zones  for  which  the  delay  is  running  switch  immediately  to  the 
alarm condition with siren output ON. 

 

SILENCE/REARM 
SIRENS 

This key silences the active siren outputs and rearms the siren outputs previously silenced. 
If the passwords are enabled, the user is required to enter the level 2 password. 
The usage of this key leads to the storage of an event in the event log. 

 

MASTER ALARM 

This key triggers a master alarm condition. 
If the passwords are enabled, the user is required to enter the level 2 password. 
The usage of this key leads to the storage of an event in the event log. 

 

TEST LAMP 

This key starts the test lamp procedure, which activates the buzzer and turns all the LEDs 
ON simultaneously, for a period of 3 seconds.

screen which makes it possible to regulate the sharpness of the display. 

 

GLOBAL RESET 

This  key  starts  the  “global  reset”  procedure.  This  procedure  clears  any  alarm  and  fault 
event and restores the outputs and relays in idle state. 
 
If the control panel is in the monitoring phase and the passwords are enabled, the user is 
required to enter the level 2 password. 
The usage of this key leads to the storage of an event in the event log. 
 
If before pressing the GLOBAL RESET key there was any alarm or fault and the causes of 
these events are still present after the reset, the events will be detected again.
